About Adaptive-CBR™
The H.264 standard admits a wide variety of tools to manipulate the compression of the video. These tools are specified in the standards profile. The ENC-400™ encoding engine uses some of these tools of advanced algorithms to get the best quality with lowest bitrates possible. For the user, Teracue’s Adaptive-CBR algorithm enables a proximity bitrate for complex scenes by saving bandwidth in order to achieve the highest quality with less data rate. This gives the user the safety that the bitrate is not going to overload the max. Bandwidth of a data link, but also does not dissipate bandwidth if it will not be required. The nature of constant bit rate (CBR) is to use the same amount of data for every video frame, regardless if even less complex scenes does not require that load of bitrate. The nature of variable bitrate (VBR) is to use only the amount of data for a predefined quality, which results in the fact that the bitrate could be less or more.
Figure 21 Video Bitrate
With our Adaptive-CBR™ bitrate control, we combine the best of CBR and VBR modes. We limit the amount of data in complex scenes to the maximum defined bandwidth of the data link, but reduce the bitrate if not required to accomplish the best quality. Adaptive-CBR™ gives you the highest quality but do not overload your data link and saves bandwidth if not needed.

ENC-400™ H.264 Encoder User Guide V1.4 The Pro-MPEG-FEC feature is an additionally option which must be purchased separately. The ‘SYSTEM SETTINGS’ menu shows whether your encoder has FEC license enabled, see chapter 3.7.1. With the FEC feature (Forward Error Correction) the encoder creates check sums which are sent to the destination. If a packet loss occurs, the destination can reconstruct the lost packet via the check sums. Therefore FEC creates a packet matrix at the encoder side. This packet matrix consists of FEC rows and FEC columns from which row check sums and column check sums will be generated (FEC algorithm = XOR). For detailed information about Pro MPEG-FEC, please see the free of charge specification www.pro-mpeg.org/documents/wancop3.pdf. .!.
The FEC settings of the ENC-400™ are set: 1 Dimensions 20 Rows 5 Columns.
If FEC is used, the encoder sends always additional data to enable the reconstruction of lost data, regardless if needed or not. This overhead leads to some increase in the data rate. In the case of ENC400, 2d-FEC creates overhead of +25% but on the other hand no return channel is needed. This is similar to other FEC used e.g. on DVB-S,-C,-T transmissions (ReedSolomon, Viterbi, BCH, LDPC). FEC is only specified on MPEG-TS via RTP transmissions. The performance of the FEC is always a tradeoff between latency, overhead and error correction capabilities. FECs with large dimensions, e.g. 20x5, 10x10 provide less overhead (+5%, +20%), but have larger latency and slightly inferior correction capabilities compared to FECs with smaller dimensions. The additional FEC data are transmitted over the same Ethernet link and the same IP address like the MPEG-TS data. But the port number of the FEC data is different from the MPEG-TS data. At 1D-FEC, the FEC data are transmitted 2 port numbers over the port number of the MPEG-TS data. At 2D-FEC, the FEC data are transmitted 2 and 4 port numbers over the MPEG-TS port number. For example, the port number of MPEG-TS data is 4444 then the port number for the FEC data is 4446 at 1D-FEC or 4446 and 4448 at 2D-FEC. So also decoders without FEC capabilities are able to receive the stream, of course without the possibility to reconstruct lost packets. FEC induces additional latency in the transmission. If a FEC packet matrix of 20x5 is chosen, a latency of approximately 260 msec. is additionally added. Smaller sized FEC packet matrixes and transmissions with higher bitrates will add less delay. Overhead in data rate, added by 2D-FEC, can be calculated by following formula: 2𝐷-𝐹𝐸𝐶 𝑂𝑣𝑒𝑟ℎ𝑒𝑎𝑑 𝑖𝑛 % =
(𝑟𝑜𝑤𝑠 + 𝑐𝑜𝑙𝑢𝑚𝑛𝑠) ∗ 100% (𝑟𝑜𝑤𝑠 ∗ 𝑐𝑜𝑙𝑢𝑚𝑛𝑠)
Overhead in data rate, added by 1D-FEC, can be calculated by following formula: 1 ∗ 100% 𝑟𝑜𝑤𝑠 On real networks there is no 100% probability, that a packet reaches its desired destination, that means: the probability that a packet gets lost is >0%. The worse the network is the higher is the probability of lost packets. 1𝐷-𝐹𝐸𝐶 𝑂𝑣𝑒𝑟ℎ𝑒𝑎𝑑 𝑖𝑛 % =
If you transmit a MPEG-TS with 8 Mbit/sec data rate without FEC, each lost packet could cause visible/ audible effects. With FEC, you would expect one unrecoverable packet approx. all 2 weeks. The DEC-300 auto configures itself to the FEC parameters used in the incoming stream. Only ‘RTP/FEC’ as transport protocol, the used ‘FEC Dimension’ and the source IP-address with port must be set on the DEC-300.

Output HLS
Also called HTTP Live streaming is an HTTP based media streaming protocol invented by Apple Inc. It works by breaking the overall stream into a sequence of small HTTP-based file downloads, each download loading one short chunk of an overall potentially unbounded transport stream. If a client connects to the encoder using HLS streaming, it downloads the m3u8 index file the encoder provides. It contains information how to stick together the segmented files to have an ongoing video stream. As it is a file based streaming, off course it has higher latency compared to other protocols. .!. .!. .!.
HLS is a good choice for Wireless transmission. HLS delay of ENC-400™ is between 5 s and 30 s related to the client. Encoder must set to Low Delay for HLS streaming.

Menu: Network/ SNMP (Simple Network Management Protocol)
The Simple Network Management Protocol enables you to monitor and/ or configure network attached devices like the ENC-400™, made possible by the installed SNMP agents. Every ENC-400™ since Firmware Version 2.09_w90 is delivered with an SNMP agent. All you need are the MIB (Management Information Base) files. With these MIB files you can use all advantages of SNMP associated with the ENC-400™. You can find the appropriate MIB files, ‘TERACUE-ENC400-MIB.txt’ and ‘TERACUE-SNMP-MIB.txt’ on the Teracue website IPTV Support Area, or contact
[email protected]. With these MIBs and a SNMP manager, you have the possibility, to monitor the ENC-400™ status (by SNMP traps) or remotely configure every function of the ENC-400™ similar to the normal access via your web browser. There are various SNMP management-tools available to issue SNMP based commands to the appliance (Software not supplied by Teracue). .!.
Set your SNMP manager to SNMPv2.
Teracue uses the MIB Browser by iReasoning to monitor andset up the ENC-400™. iReasoning offers a free version of the MIB Browser under www.ireasoning.com, which is useful to read the actual status or setting up the ENC-400™. See further information about the MIB Browser of iReasoning in chapter 3.5.3 on page 47. .!. SNMP uses the following standard ports: Port 161 and port 162. Port 161 is used by the SNMP manager and the agent to send the requests and their responses. Port 162 is used by the SNMP agent to send TRAPs to the SNMP manager. Make sure that these ports are not blocked in your network. The following operations are possible with SNMP: GET: Read out the management information. GETNEXT: Read out the management information iteratively, this is useful when you want to read the information down the MIB tree step by step. GETBULK: Read out the management information of the complete list/ tree. SET: Change/ set the management information. TRAP: Start the Trap receiver in your SNMP manager to get alerts of the managed system. E.g. the encoder was started / stopped. To use the ENC-400™ SNMP features, you have to set up the encoder, to establish access with your SNMP manager.

The fields ‘Location’, ‘Contact’ and ‘Name’ describe the common SNMP-parameters (sysLocation, sysContact and sysName) supported by every SNMP device. These details help you to find and identify SNMP devices like the ENC-400™ in a network. The SNMP elements use traps as SNMP base messages to report changes in status or alarm conditions to remote SNMP management entities. Normally traps are used to alarm network administrators of possible equipment problems or other important events. There are two types of information sent by the trap device: ‘Events’ and ‘Alarms’. ‘Event’ traps will be sent if a monitored event occurs. These traps have only one state. ‘Alarm’ traps are events that have two states: Active and Clear. An ‘Active’ trap will be sent if an alarm condition will be detected. The alarm will be kept active until the condition cleared and a ‘Clear’ trap was send. The ENC-300™ has the following trap alerts: Trap Name: Enc400InputLockStatus: Enc400GpioStatus:
Description: This trap is sent when the ‘Input locked’ status of the ENC-400™ has changed. The trap contains the new status variable (yes/ no). This trap is sent when the ‘GPIO’ status of the ENC-400™ has changed. The trap contains the new status value (1/0).

Sub Menu: Comport
The ‘Comport / Settings’ menu defines the parameters for the ENC's integrated comport/serial port. ENC-400™ encoders are always comport servers while DEC-200™ and DEC-300™ decoders are always comport clients.

Mode:
Bitrate: Data Bits: Parity: Stop Bits:
Description: Specifies the Comport Mode. ‘Console’ enables access and control of the ENC-400™ configuration via the com-cable. ‘Passthrough’ enables the comport setting to a serial mode. RS-232 devices can be connected and controlled via comport. This is useful, for example when cameras or other non-IP, non-network devices need to be remotely controlled. RS-232 commands can be tunneled and sent via TCP/IP to comport server, where they will be returned into native RS-232 commands. When a connection is opened from the client (e.g. decoder) to the IP-address of the encoder at port 7777, the serial function in the ENC-400™ is activated and any data (string) is passed straight to the connected RS-232 device. Once the connection is established, this also works the other way for information coming back from the RS-232 device. Specifies the used Bitrate in bits per second. Specifies the data bits. You can choose between ‘7’ and ‘8’. This field is only available when the comport mode ‘Passthrough’ is chosen. Specifies the Parity. You can choose between ‘none’, ‘odd’ and ‘even’. This field is only available when the comport mode ‘Passthrough’ is chosen. Specifies the value of used stop bits. You can choose between ‘1’ and ‘2’. This field is only available when the comport mode ‘Passthrough’ is chosen. Set and save the settings

Each ENC-400™ has a unique, self-generated certificate for HTTPS Internet access to the user interface. Since the ENC-400™ certificate is not known to any certification authority, or to the computer's local certificate administration; the web browser displays a certificate warning when you try to access the ENC-400™ with HTTPS. The certificate warning only means that the browser cannot verify the authenticity and integrity of the ENC-400™. Even if the browser claims that the connection is insecure, opening the ENC-400™ user interface does not pose a security risk! You can avoid the certificate warning by downloading the unique certificate generated by the ENC400™ itself and importing it to the computer's certificate administration.

Remote Control
This chapter describes the remote control of the ENC-400™ for media controls like Crestron or AMX. To control the ENC-400™, the telnet protocol is used at the port number 2323, furthermore no login needed. To test the ‘remote control’ with windows, use either a Terminal program like Putty or the ‘windows terminal client’ have to be installed under ‘program and features’. To open a new commando prompt press WIN+R write ‘cmd’ in the text field and hit ‘Enter’ or click the ‘OK’ button.

ENC-400™ H.264 Encoder User Guide V1.4 For starting a telnet session type: telnet
<2323>, e.g. ‘telnet 172.16.20.100 2323’, and press the Enter button. See Figure 79. The value ‘2323’ specifies the used TCP/IP port number for the telnet session of the remote control test. The IP-address should correspond to the ENC's IP-address.
Figure 79: Starting a telnet session for the remote control test
Figure 80: Session to test the remote control of the ENC-400™
After the session is successfully established SDECRP is displayed, see Figure 80 The command ‘help’ will display a list of all available options. The ‘ls’ command, shows all available directories and options, in the current directory. To change the current directory, write ‘cd directory name’, e.g. ‘cd status’. To move back up a level use ‘cd ..’:. If you enter the command ‘exit’, the telnet session will close. Wildcard * is possible, e.g. cd co* to change to directory ‘configuration. If you want to enter the value of an option, you must use the ‘put’ command followed by the correct values. Afterwards use the ‘apply’ and ‘save’ commands to apply and/or save your changes. .!.
Example: E.g. for changing the destination TS IP-address of Stream 1, you need to type the following: put /configuration/outputs/ts/streams/stream1/destination 239.252.20.100 apply save
.!.
Figure 81 provides an overview over the telnet navigational and directory structure to test the remote control. This overview is useful to find the correct configuration settings when navigating in telnet mode. For instructions and descriptions on the individual settings, please see the corresponding chapters for web based configuration. This overview is not exhaustive

Glossary Description Audio Codec (Advanced Audio Codec) is an audio coding standard for lossy digital audio compression. AAC generally achieves better sound quality than MP3 at similar bit rates. There are different AAC profile most used ones are: LC-AAC (Low complexity) for medium to High Bitrate HE-AAC (High efficiency) Hi efficiency is optimized for low Bitrate (32-80 kbit/s) With the 128 bit AES Encryption the TS is complete encrypted with all PID`s, but is recognized as a Transport stream. With Teracue Tools the encrypted TS can be recorded and playout with a constant Bitrate (iCue Pump Lite), but only MC-Route is able for decrypting. The Delay between Input and output is < 1 Frame. The ‘Asynchronous Serial Interface’ is a streaming data format which carries an Transport Stream (MPEG-TS). An ASI signal can carry one or multiple SD, HD or audio programs that are already compressed, as opposed to an uncompressed SDI Signal. In digital transmission (DVB), the number of bit errors is the number of received bits of a data stream over a communication channel that have been altered due to noise, interference, distortion or bit synchronization errors. The ‘bit error ratio’ is the number of bit errors per time. The number should be very small like 0.0e-8 or better 0.0e-9 The ‘Basic Interoperable Scrambling System’ is a simple scrambling system. BISS-1 transmissions are protected by a 12 digit hexadecimal "session key" that is agreed by the transmitting and receiving parties prior to transmission. The key is entered into both the encoder and decoder, this key then forms part of the encryption of the digital TV signal and any receiver with BISS-support with the correct key will decrypt the signal. BISS-E (E for encrypted) is an variation where the decoder has stored one secret BISS-key entered by for example a rights holder. This is unknown to the user of the decoder. The user is then sent a 16-digit hexadecimal code, which is entered as a "session key". This session key is then mathematically combined internally to calculate a BISS-1 key that can decrypt the signal. The ‘carrier-to-noise ratio’ closely related to the EB_NO, and is an important parameter in digital communication or data transmission (DVB). This ratio between Signal and noise should be high like 12.0 dB or better 14.0 dB The ‘conditional access module’ is an electronic device, usually incorporating a slot for a smart card, which equips an Integrated Digital Television or set-top box with the appropriate hardware facility to view conditional access content that has been encrypted using a conditional access system. Constant Bitrate used in Encoding and in Multiplexing. In Encoding difficult content will result in lower quality to have nearly a constant output. In Transport stream additional packets are added to the stream to have a constant stream. These Packets are called padding or stuffing packets and are thrown away from the decoder. The ‘Common Interface’ allow to insert an CAM. The ‘Digital Video Broadcasting’ is a suite of internationally accepted open standards for digital television. DVB standards are maintained by the DVB Project, an international industry consortium with more than 270 members, and are published by a Joint Technical Committee (JTC) of the European Telecommunications Standards Institute (ETSI) mostly used are: DVB-C – Cable DVB-T or DVB-T2 - Terrestrial DVB-S or DVB-S2 - Satellite The ‘energy per bit to noise power spectral density ratio’ closely related to the C/N, and is an important parameter in digital communication or data transmission (DVB). It is a normalized signal-to-noise ratio. This ratio between Signal and noise should be high like 9.0 dB or better 11.0 dB

Description The ‘Event Information Table’ can deliver different information’s: Present/following - actual and next TV Program Other - event schedule information up to 30 Days Needed for EPG, without EIT the EDID Data cannot be decoded. The ETSI EN 300 468 standard contains detailed information about EIT The ‘Electronic program guide’ deliver information about the running and upcoming TV Program. That a Decoder is able to decode EPG following Tables have to be included in the Transport Stream: EIT TOT/TDT An elementary stream as defined by MPEG communication protocol is usually the output of an audio or video encoder. ES contains only one kind of data, e.g. audio, video or closed caption. An elementary stream is often referred to as “elementary”, “data”, “audio”, or “video” bit streams or streams. The format of the elementary stream depends upon the codec or data carried in the stream, but will often carry a common header when packetized into a packetized elementary stream. Can be Unicast and Multicast Flooding Multicast Flooding happen in Network environments they are not, or wrong configured. As result a multicast is send to all Network Ports, This can be controlled with Network Sniffer like Wireshark. UDP Flooding is also a result of misconfigured Network Environments. Packets sent to a Unicast IP-Address who is not available will also sent to all Network Ports. On most switches the configuration can be found in menu IGMP Snooping, please refer the Switch manual. Is a Video Codec. While the ITU-T called it H.264 the Moving Picture Experts Group called it MPEG-4 Part 10, Advanced Video Coding (MPEG-4 AVC) H.264 generally achieves better video quality than MPEG2 at similar bit rates. While same quality result in around 40% lower bitrate. Or also called HTTP Live streaming is an HTTP based media streaming protocol invented by Apple Inc. It works by breaking the overall stream into a sequence of small HTTP-based file downloads, each download loading one short chunk of an overall potentially unbounded transport stream. The Internet Control Message Protocol is part of the Internet Protocol Suite Ping is Part of ICMP The Internet Group Management Protocol is a communications protocol used by hosts and switches on Ipv4 networks to establish multicast group memberships. IGMP is an integral part of IP multicast. IGMP is used for one-to-many networking applications. Specifies the interval of intra frames. Intra frames (= I-Frames) are total independently coded and are used as references frames. At the ENC-400™ the data volume of a P-Frame amounts between 5% and 20% of an I-Frame. This assumed of an average data volume of 10%, it means that for one IFrame or ten P-Frames the same data volume is needed. The H.264 standard allows long GOPs. More P-Frames at the same data rate means also a better quality. But more P-Frames have two disadvantages: 1) The decoder can start the decoding process not until the decoder get an I-Frame. That means at a GOP of 500 frames, the decoder waits in worst-case 20 seconds before a picture is displayed. 2) In occurrence of network errors (high packet loss), Frame gaps of up to 20 seconds can occur. The lower the GOP, the higher are the robustness and the faster can be decoded. M-JPEG is an intra frame only compression scheme. M-JPEG imposes lower processing and memory requirements on hardware devices than H.264, but result in compression ratio 1:50.

Description IP multicast is a technique for one-to-many communication over an IP infrastructure in a network. The destination nodes send join and leave messages, IP multicast scales to a larger receiver population by not requiring prior knowledge of who or how many receivers there are. Multicast uses network infrastructure efficiently by requiring the source to send a packet only once, even if it needs to be delivered to a large number of receivers. The nodes in the network take care of replicating the packet to reach multiple receivers only when necessary. The most common transport layer protocol to use multicast addressing is User Datagram Protocol (UDP). By its nature, UDP is not reliable—messages may be lost or delivered out of order. If you use Multicast in you Network separate the different Multicast by the Multicast-IP and not by the Port. Because only the Client separate the Port, Switches do not. Means if you send several stream to same Multicast IP but different Ports, clients will receive them all when they request one of them. The Network Information Table can be part of a TS. This optional table may group transport stream identifiers into a network, providing access parameters and other details. Program Association Table The PAT is assigned PID 0x0000 and table id of 0x00. The transport stream contains at least one or more TS packets with PID 0x0000. Some of these consecutive packets form the PAT. At the decoder side, the PSI section filter listens to the incoming TS packets. After the filter identifies the PAT table, they assemble the packet and decode it. A PAT has information about all the programs contained in the TS. The PAT contains information showing the association of Program Map Table PID and Program Number. Quality of Service, or Differentiated services DiffServ uses a 6-bit differentiated services code point (DSCP) in the 8-bit differentiated services field (DS field) in the IP header for packet classification purposes. The DS field and ECN field replace the outdated IPv4 TOS field. Routers and switches can be configured to prefer packets with a DSCP value. Other packets have to wait until the QOS packets are sent. QOS do not work in public Internet. The Program Map Table is Part of a TS and contains PID numbers of elementary streams associated with the program and it has information about the type of these elementary streams (video, audio, etc.). Real Time Messaging Protocol or also called Flash ) was initially a proprietary protocol developed by Macromedia for streaming audio, video and data over the Internet, between a Flash player and a server. Macromedia is now owned by Adobe, The Real-time Transport Protocol is a network protocol for delivering audio and video over IP networks. In addition to UDP, it add a counter and time information. While for TS this information are unnecessary, it is important for RTSP/RTP transmission for ES. The Real Time Streaming Protocol is a network control protocol designed for use in entertainment and communications systems to control streaming media servers. The protocol is used for establishing and controlling media sessions between end points. Clients of media servers issue VCR-style commands, such as play and pause. The Transmission itself is done via UDP RTP as Transport or Elementary stream. Round Trip Time = Ping Time= Time to receive answer from another node. See TCP Window Size The Session Announcement Protocol (SAP) is a protocol for broadcasting multicast session information. A SAP listening application can listen to the well-known SAP multicast address and construct a guide of all advertised multicast sessions. SAP was published by the IETF as RFC 2974. According to this specification and standard SAPs are sent on the multicast address 224.2.127.254 on port 9875. SAP is used to label a stream to guarantee an effective workflow. Streams with SAPs can easily be located, selected and viewed – due to their description. Please see the figure below to get an overview of all the properties that can be defined.

Description The ‘Serial Digital Interface’ used in Broadcast environment, transporting uncompressed Video and Audio Signals. There are different Standards like: 3G-SDI Bitrate 2,970 GBit/s 6G-SDI Bitrate 6 Gbit/s 12G-SDI Bitrate 12 Gbit/s The Service Description Table can be part of the TS and describes services that are contained in a particular transport stream. Such services are the service name and the service provider. The ETSI EN 300 468 standard contains a detailed information about SDT. Signal Strength by DVB receiver. Mostly critical by DVB-C receiver can be even to big and need a attenuator to reduce the signal strength Transmission Control Protocol is a connection-oriented protocol, which means that it requires handshaking to set up end-to-end communications. Once a connection is set up, user data may be sent bi-directionally over the connection. TCP Receive Window also called RWIN RWIN (Send buffer) is limiting the Bandwith, max Bandwith = RWIN/RTT. In doubt bigger RWIN is better than a small RWIN If ping time is higher than 30 ms only lower Bitrates (> 4Mbit/s) are realistic. MPEG transport stream (MPEG-TS, MTS or TS) is a standard container format for transmission and storage of audio, video, and It is used in broadcast systems such as DVB, ATSC and IPTV. Transport Stream is specified in MPEG-2 Part 1, TS specifies a container format encapsulating packetized elementary streams. Teracrypt is a proprietary encryption used on ENC-300™ and ENC-400™ The output is not usable for any other Video Device. They will not even recognize it as a Transport Stream. It is also not usable for recording. Best practice are Multicast Destination. You can decrypt this Stream only with Teracue: DEC-300 FW 2.10 or higher X-Player Version 4.0.0.125 or higher The ‘Time Offset Table’ and ‘Time and Date’ Table carries the UTC Time and Date information and the TOT added with the Time offset. Needed for EPG, without TOT/TDT the EPG Data can not be decoded. The ETSI EN 300 468 standard contains a detailed information about TOT and TDT User Datagram Protocol is a simpler message-based connectionless protocol. Connectionless protocols do not set up a dedicated end-to-end connection. Communication is achieved by transmitting information in one direction from source to destination without verifying the readiness or state of the receiver. Unicast might be the standard communication between Nodes one to one. Every Web browser or Mail communication is a Unicast communication. ENC-400-HDMI™ is also able in for Unicast communication. More efficiency is the Multicast communication. Variable Bitrate will result in lower delay than CBR and save resources in Network communication and recording space. But result in more difficult decoding engines. Also on leased lines with maximum bitrate VBR should not be the choice.
