SVP 5500 HEVC Encoder
1.2.1
Overview The Ericsson SVP 5500 series Encoders are versatile audio/video processing platforms designed for encoding and transcoding of audio and video signals for IPTV, Mobile TV (3G, DVB-H, ATSC M/H) and Web TV markets (Flash, WMF). They feature flexible input configuration baseband encoding and transcoding. The SVP 5500 HEVC Encoder is capable of accepting uncompressed SDI video, or either compressed MPEG-2 or MPEG-4 AVC transport stream over an IP input. Processing can include audio and/or video codec change, frame size change, frame rate change, video/audio bit rate change, etc. The output media is compressed audio/video: MPEG-2, H.263, MPEG-4 SP, MPEG-4 AVC, or WMV. The SVP 5500 Encoder can output streams using MPEG-DASH segmentation. Dynamic Adaptive Streaming over HTTP (DASH) simplifies and standardizes the adaptive delivery of video to consumer devices, ensuring a better quality of service, and greater efficiency. An option is available whereby the HEVC stream can also be stored as file for later transmission.
1.2.2
Maximum Number of Profiles Number of independent audio/video programs that a single unit is able to process. For instance, Maximum Number of Profiles is four if the user can set the unit to encode or transcode four different programs, with different codecs, and different bit rates. A device might be able to deliver four profiles but ingest only two feeds. This means that a maximum of two input streams may be processed in a total of four different ways. Also, a device might be able to handle four profiles, but allowed to handle only two, depending on the license configuration. If this is the case, the user may upgrade the license to handle more profiles, until the maximum device capacity is reached.
1.2.3
Summary of Features

Frame only
Setting for encoding stream only with frames, no fields
Should be used only for non interlaced inputs
Slide show mode
In show mode, each GOP is encoded with the same picture.
Often with a low frame rate, like a slide show.
Key frames alignment
Enable the IDR alignment between video profiles
Enable frame interpolation
When upsampling the frame rate, frame interpolation creates the missing frames between already existing frames
No B frames
Forbid B-frames in encoding, only I-frames or P frames

Auto colour enhancement
Performs an automatic setting of the brightness, contrast, gamma and saturation parameters
Brightness
Brightness makes the video darker or brighter
The value can be set from -100 to 100. It affects all pixels linearly, unlike the Contrast filter which makes dark pixels become darker and bright pixels brighter
Contrast
Contrast adjustment makes the dark pixels darker and the lighter pixels lighter
Be careful not to increase the contrast too much as the lighter pixels have a tendency to become a white blur. By lowering the contrast, the image will become more flat or greyish.

Description
Notes
Gamma
Gamma is probably the most common filter to use and might be the most important correction to do
Gamma compensates for the differences between different display technologies and devices, such as when encoding for handheld devices and terminals, targeting Mac/PC, etc. Gamma is a non-linear filter. It only affects the midrange tones but leaves the darkest and lightest parts unchanged. This is useful for darkening or lightening a picture without the risk of distorting the white areas. Positive numbers (1 to 100) make the image lighter. Negative numbers (-1 to -100) make the image darker
Saturation
Saturation changes the intensity of the color
Moving the slider to the right(increasing the values), intensifies the colors, and vice versa. The value can be set from -100 to 100

AFT provides automatic redundancy for a server's network connection. If the primary adapter fails, the secondary adapter takes over. All team members must be connected to the same device.
-
SFT provides a failover relationship between two adapters when each adapter is connected to a separate switch. Spanning Tree Protocol (STP) must be enabled when a team is created in SFT mode.

FAQs
How is an Output Frame Rate of 23.97fps configured? From Video Encoding pane, set Output Frame Rate to Custom = 24000/1001.
Figure 6.2 Video Encoding – Set 23.97 fps
What is the GOP size? The GOP size is the time period between two I frames.
What is an IDR frame? An IDR frame is a special type of I-frame in H.264. An IDR frame specifies that no frame after the IDR frame can reference any frame before it.
What is Key-Frame Alignment parameter? Key-frame alignment parameter allows to generate H264 streams IDR aligned. It is mandatory for ABR (Adaptive Bitrate Rate).
What is the difference between Aspect ratio conversion and Aspect ratio signaling? Aspect ratio conversion allows output aspect ratio to change while preserving the input aspect ratio.
Note:
6-4
If source aspect spect ratio is 16/9, and Aspect ratio conversion is set to 4/3, black bars will be encoded at the top and at the bottom (letterbox) to preserve source aspect ratio.
EN/LZT 790 0027/1 R1A
Encoding
Figure 6.3 Aspect Ratio Conversion - Letterbox Output Aspect ratio signaling allows to change output aspect ratio, but without preserving input aspect ratio. This tuning may be helpful to correct a misdeclared aspect ratio into the source. Note:
If Aspect ratio signaling is not correctly configured, the output stream may be deformed. Recommended value is pass-through.
Which bit rates and resolutions to use? If there is doubt as to what bit rates and resolutions to use, or have no specific requirements for that, then it is suggested to define bit rates and resolutions as a geometric progression. For instance, if it is required to use a maximum bit rate of 3000 kbps, and minimum bit rate of 400 kbps, and four levels in-between (i.e. five intermediate levels, six levels in total), then the ratio between each bit rate shall be equal to exp(ln(3000/400)/5) = 1.49. In our example, the six bit rates are: 400 kbps, 599, 896, 1340, 2005, 3000 kbps. The same rationale applies for resolutions: if a maximum resolution of 1280x720, and minimum resolution of 320x176, and still four levels in-between is required, then the ratio between each resolution is equal to exp(ln(1280/320)/5) = 1.32 horizontally. In the example, the six horizontal resolutions are: 320, 422, 557, 735, 970, 1280 px. As there are multiples of 16, the following horizontal resolutions: 320, 416, 560, 736, 976, 1280 px can be used. If square pixels in a 16:9 display aspect ratio are required, then the six vertical resolutions are: 180, 234, 315, 414, 549, 720.

FAQs
What is the duration of service interruption when a Main unit failure is detected? A Hot-Spare unit starts up in 5-10 seconds after a Main unit failure. The observed total blackout time is 20 seconds (startup time + connection to streaming server + device decoding time).
Can I configure the spare unit to start if Main unit's output stream is no more delivered? No, sparing feature was designed to prevent hardware failures. Sparing is triggered when a Main unit is not responding (ping request).
Introduction The SVP 5500 device may be configured for device level redundancy. The basic principle is that one device can be a redundant spare for the other device. So-called Hot-Spare units and Main units are strictly identical, but configured in a different way. A Hot-Spare unit can be configured to monitor one or several Main units. When one of the monitored Main units fails, the Hot-Spare unit starts working, running with the Main's last known parameters. The Hot-Spare unit generates an SNMP trap to signal it has started. The operator must then have a manual action: checking what's wrong with the Main unit, fixing it, then restarting it and stopping the Hot-Spare unit. One same Main unit may be monitored by several Hot-Spare units. If this Main unit fails, only one Hot-Spare unit will start; the other Hot-Spare units will continue monitoring the other Main units they have to monitor.
8.3
Configuration
Configuration is completely flexible, allowing any N+P redundancy scheme.
One same Main unit can be monitored by none, one, or several Hot-Spare units
One Hot-Spare unit may monitor and spare one or several Main units (at least one)

Operation
8.4.1
Introduction A Hot-Spare unit scans each Main unit, getting configuration, and checking if the Main unit is still responding. This checking is done by a ping-like command. Notes: Life checking is done every two seconds by the Hot-Spare unit. Hot-Spare unit gets the Main unit's configuration every 20 seconds An operational network is needed for carrying the life signal. Most of the time, it is the data out network.
8.4.2
Input Configuration When a Hot-Spare units starts, it needs to have the same input data than the device it is sparing. If the input audio/video stream is carried on Ethernet, this is quite easily achieved by connecting the Hot-Spare unit on the same video network as the Main unit. If the input audio/video stream is carried on SDI, the Hot-Spare unit must be connected to the same SDI source as the Main unit. If this requires external electrical operation such as grid switching, this operation needs to be handled separately.
8.4.3
Sparing Steps Main unit failure: Main unit failure is detected by Hot-Spare unit. Hot-Spare unit starts the Main unit's encoding services with its last known configuration. Note:
EN/LZT 790 0027/1 R1A
Hot-Spare unit status is changed from Monitoring to Sparing.
8-5
Redundancy and Spare Units
Hot-Spare device parameters (IP configuration, time synchronization settings) are not modified when spare unit starts. From a network point of view, Hot-Spare unit is not strictly identical to Main unit, since it has different MAC addresses and IP addresses. Main unit issue is fixed and server is restarted: Main unit goes back to life, but its encoding services are not started to avoid double publication (keep in mind that HotSpare unit is still running) Note:
Main unit status is Standby to avoid double publication.
Stop sparing: To stop sparing and transfer services to the Main unit, press the Stop Sparing button on the Hot-Spare unit.
Figure 8.4 Redundancy Tab – Stop Sparing Notes: Main unit status is changed from Standby to Running. Hot-Spare unit status is changed from Sparing to Monitoring. If channel settings are changed on the Hot-Spare unit, modification won't be applied to the Main unit when clicking Stop sparing.
8.4.4
Sparing and SFT Teaming If the lifesign is carried by a SFT teamed network, when the primary cable of the hotSpare unit is disconnected, the lifesign tries to go from the secondary team connector on the network, to the secondary connector of the team on the Main unit. Problem: Since the Main unit works properly, the secondary port of its team remains in standby and does not respond to the lifesign, which results in an erroneous start of the Hot-Spare unit. Solution: For this not to happen, we recommend to inter connect the two switches, so that the lifesign can go from the secondary connector of the Hot-Spare unit, to the primary port on the Main unit.

Overview REST is a style of software architecture that provides a convenient and consistent approach to requesting and modifying data. The term REST is short for Representational State Transfer. In the context of SVP 5500 Low Level API, it refers to using HTTP verbs to retrieve and modify the configuration of SVP 5500. A client sends a request that the device perform a particular action (such as creating, retrieving, updating, or deleting a configuration item), and the transcoder performs the action and sends a response. In SVP 5500's RESTful APIs, the client specifies an action using an HTTP verb such as POST or GET. It specifies a resource by a globally-unique URI of the following form:
9.2
http://address/objects/device/{configurationItem}
http://address/objects/channels/{channelId}/{configurationItem}
Data Format The data format used by the Low Level API is JSON. JavaScript Object Notation (JSON) is a common, language-independent data format that provides a simple text representation of arbitrary data structures. For more information, see json.org.
9.3

Channel Coding
A way of encoding data in a communications channel that adds patterns of redundancy into the transmission path in order to improve the error rate. Such methods are widely used in wireless communications.
Chrominance
The color part of a TV picture signal, relating to the hue and saturation but not to the luminance (brightness) of the signal. In a composite-coded color system, the color information (chrominance, often referred to as chroma) is modulated onto a high frequency carrier and added to the monochrome-format video signal carrying the luminance (Y). In a component-coded color system, the two color-difference signals (R-Y)(B-Y) usually referred to as CRCB (digital) or PRPB (analogue), are used to convey color information. When CRCB (PRPB) is added to the luminance (Y), the complete picture information is conveyed as YCRCB (YPRPB).
Closed Captioning

CODE
Create Once Distribute Everywhere.
Codec
The combination of an Encoder and a complementary Decoder located respectively at the input and output of a transmission path.
COFDM
Coded OFDM: COFDM adds forward error correction to the OFDM transmission consisting of Reed-Solomon (RS) coding followed by convolutional coding to add extra bits to the transmitted signal. This allows a large number of errors at the receive end to be corrected by convolutional (Viterbi) decoding followed by RS decoding.
Composite
CVBS Video Signal, 1 V pk-pk
Compression
Reduction in the number of bits used to represent the same information. For the purposes of a broadcast system, it is the process of reducing digital picture information by discarding redundant portions of information that are not required when reconstituting the picture to produce viewing clarity. Compression allows a higher bite-rate to be transmitted through a given bandwidth.
Compression System
Responsible for compressing and multiplexing the video / audio / data bitstreams, together with the authorization stream. The multiplexed data stream is then ready for transmission.
C RC B
Digital Color difference signals. These signals, in combination with the luminance signal (Y), define the color and brightness of each picture element (pixel) on a TV line. See: Chrominance
CRC
Cyclic Redundancy Check: A mathematical algorithm that computes a numerical value based on the bits in a block of data. This number is transmitted with the data and the receiver uses this information and the same algorithm to ensure the accurate delivery of data by comparing the results of algorithm and the number received. If a mismatch occurs, an error in transmission is presumed.
CVBS

dB
Decibels: A ratio of one quantity to another using a logarithmic scale, to give results related to human aural or visual perception. dB is a ratio of two quantities. dBm, for example, is an absolute power level, quoted as a ratio to a fixed power of 1 mW (0 dBm), typically terminatedinto 50 Ω (RF) or 600 Ω (audio). 0 dBmV is 1 mV across 75 Ω.
DCE
Data Communications Equipment: Typically a modem. It establishes, maintains and terminates a session on a network but in itself is not the source (originator) or destination (end receiving unit) of signals (e.g. a computer, see DTE). A DCE device may also convert signals to comply with the transmission path (network) format.
DCT
Discrete Cosine Transform: A technique for expressing a waveform as a weighted sum of cosines. Raw video data is not readily compressible. DCT is not in itself a compression technique but is used to process the video data so that it is compressible by an encoder. DCT processes the picture on an 8x8-pixel block basis, converting the data from an uncompressible X Y form (as displayed by an oscilloscope) to a compressible frequency domain form (as displayed by a spectrum analyzer). Can be forward DCT or inverse DCT.
DDS
Direct Digital Synthesiser.
Decoder
The unit containing the electronic circuitry necessary to decode encrypted signals. Some Decoders are separate from the receiver but in satellite TV broadcasting, the term is often used interchangeably as a name for an Integrated Receiver Decoder (IRD). The term IRD, or IRD / Decoder, is usually associated with satellite TV broadcasting while Cable systems are based on Converters or on Set-Top Boxes / Converters.

Materials
B.11
Overview Ericsson products are designed and manufactured in keeping with good environmental practice. Our component and materials selection policy prohibits the use of a range of potentially hazardous materials. In addition, we comply with relevant environmental legislation.
EN/LZT 790 0027/1 R1A
B-9
Technical Specification
B.12
For the European Union We comply with the EU RoHS Directive 2011/65/EU on the restriction of the use of certain hazardous substances in electrical and electronic equipment. We also comply with the WEEE and REACH Directives.
B.13
For China For product sold into China after 1st March 2007, we comply with the “Administrative Measure on the Control of Pollution by Electronic Information Products”. In the first stage of this legislation, content of six hazardous materials has to be declared together with a statement of the “Environmentally Friendly Use Period (EFUP)”: the time the product can be used in normal service life without leaking the hazardous materials. Ericsson expects the normal use environment to be in an equipment room at controlled temperatures (around 22°C) with moderate humidity (around 60%) and clean air, near sea level, not subject to vibration or shock. Where Ericsson product contains potentially hazardous materials, this is indicated on the product by the appropriate symbol containing the EFUP. For Ericsson products, the hazardous material content is limited to lead (Pb) in some solders. This is extremely stable in normal use and the EFUP is taken as 50 years, by comparison with the EFUP given for Digital Exchange/Switching Platform in equipment in Appendix A of “General Rule of Environment-Friendly Use Period of Electronic Information Products”. This is indicated by the product marking:
It is assumed that while the product is in normal use, any batteries associated with real-time clocks or battery-backed RAM will be replaced at the regular intervals. The EFUP relates only to the environmental impact of the product in normal use, it does not imply that the product will continue to be supported for 50 years.
