The Nucomm Messenger system enables broadband IP connectivity between an ENG/OB/SNG truck or news bureau and the Broadcast Studio. With the deployment of video editing systems into the remote vehicles or bureau, the traditional workflow is rapidly shifting. In the new workflow, stories can be edited in the field and delivered to the studio over alternative networks. With an IP network in place, other applications can also run between the studio and the ENG vehicle, such as tools for remote cueing or remote truck control. The Nucomm Messenger can be used in either Opportunistic Data Insertion (ODI) mode or broadband mode. In ODI mode, live video is sent using the MPEG encoder, reducing the IP traffic to a rate in the range of 100 Kbps to 1 Mbps. The ODI mode does this by replacing null packets within the MPEG transport stream with IP packets. In the broadband mode, nearly the entire link is dedicated to IP traffic. The user either turns off the MPEG encoder or removes the video source to the encoder, creating a transport stream nearly full of null packets. In this mode, the encapsulator responds automatically to the changing network conditions. IP Microwave Transmission from the Field
IP data from the news gathering vehicle to the studio flows through the existing ENG/SNG infrastructure. The outbound IP traffic enters the Messenger IP Intelligent router and a decision is made on the availability of back haul interfaces. If a broadband interface (ENG/SNG Link) is available, IP packets are routed to the MPEG encapsulator destined for the studio. The IP traffic is encapsulated into the MPEG stream from the MPEG Encoder in the ENG/SNG transmitter. The resulting ASI stream, containing the IP data and video data, returns to the ENG/SNG transmitter, where it is transmitted back to the studio. If the backhaul is unavailable, a rule can be defined to reject the traffic 1or route it through lower speed interfaces. IP Reception in the Field
IP traffic in the field is received through multiple connections including over-the-air VSB or COFDM, cellular networks or Wifi 802.11 b/g. (continued on back)
Messenger IP File Transfer System Nucomm has developed an intelligent multi interface network router that keeps track of the active connections and route traffic accordingly. When using a over-the-air VSB or COFDM backchannel, IP for the truck is encapsulated onto the over-the-air MPEG transport stream. A VSB/COFDM receiver located in the Messenger receives the signal, de-encapsulates the IP Traffic from the studio, and routes it out the Ethernet port to the network inside the truck. An alternative way to accomplish the return channel is by utilizing the cellular network or Wifi 802.11 b/g. An advantage to this method is that a bidirectional IP connection is constantly maintained.
Messenger Media Transfer Server (MMTS)
The Messenger has a optional media transfer server integrated into the product. This media transfer has a sync folder that media files can be transferred into and transferred seamlessly back to the studio video server or media server. MMTS has been specially designed to cope with poor quality or high latency asymmetric data links. When a link goes down, the file transfer is paused until the link is reestablished. After the momentary link error event, lost packets or packets containing errors are re-requested for transmission. Using MMTS the Messenger utilize 98% of the uplink bandwidth with as little as a 7kbps back channel. When compared to a standard FTP application MMTS achieved 10x faster transfer rate.
