Rebroadcast Internet Streaming To Local CATV

In recent years, video service providers have made significant investment to build video delivery infrastructure based on IP streaming protocols in order to serve Internet-connected devices. On the other hand, service providers still rely on legacy networks, such as QAM-based networks and closed-circuit networks to deliver video content for their customers. The networks using IP video streaming protocols will run parallel to legacy closed networks in the near future.

Traditionally, video services provided on legacy networks include locally generated video content and remote programming delivered via satellite, terrestrial or fiber transport methods. With the increasing availability of video content by Internet streaming, service providers can get abundant of video sources from the Internet using IP video streaming. Therefore, a simple solution is needed to convert Internet streaming media to UDP streams to be rebroadcasted in legacy networks.

DIBSYS Internet Streaming to Local Broadcast Gateway (DCM750M) is enabling the replacement of expensive satellite, terrestrial and fiber links that deliver compressed video to service providers, as well as links between facilities. The dcm750m hardware with build in middleware work with MiniMod provides a simple, low-cost solution for rebroadcasting Internet content in a local legacy network.

Use Case 1: Convert Internet OTT Streams to UDP Streams

The dibsys Internet Streaming to Local Broadcast Gateway (DCM750M) converts input IP streams using the HLS, RTMP, RTSP, and SRT protocols to MPEG-2 TS over UDP streams. The Gateway receives input streams via IP NIC, re-multiplexes video and audio data packets and creates a multiplexed TS and then outputs the TS in the form of UDP steams. The output UDP stream is single-program variable bit rate (VBR) or constant bit rate (CBR) TS.

Output UDP channels can be created using multicast or unicast IP addresses. A single UDP output stream can be generated from multiple input source streams that are played out according to a preconfigured time schedule. Both live input streams and VOD streams can be used as input source for UDP stream output. The playout time can be scheduled in advance with repeat options.

The software can generate up to 20 HD (Bitrate:3Mbps)or 40 SD(Bitrate:1.5Mbps)simultaneous output UDP streams in a single system with  CPU, memory and NIC configuration.

Use Case 2: Transport Live Video over the Internet using SRT

Secure Reliable Transport (SRT) is a UDP based media transport protocol with low-latency and ability of re-transmission of lost packets. The DCM750M Gateway provides a solution for transporting media using SRT. In a typical configuration, two Gateway systems can be used as two end-points. One is used as a transmitter which converts various input streams such as UDP streams to SRT streams, and the other one is used as a receiver which receives the SRT streams and convert them back to UDP streams. If a stream processor on the remote site can receive SRT streams directly, it can also be used as an end-point. In addition to UDP streams, other type of input streams including RTP, RTMP, RTSP can also be converted to SRT streams for media transport.

The dcm750M use FPGA tech ,with linux os inside that can run 24x7 unattended once the input sources and output channels are fully configured. The Device  is very easy to use and maintain.Work standalone ,dont need any other hardware.

About the miniMod,MiniMod IP to RF Gateway and Modulator is an ideal solution for environments where you have a large number of displays over almost any distance such as Small and Medium Scale of  Digital TV broadcasting System.It supports 192 IP (SPTS/MPTS) inputs over UDP/RTP with 10Ethernet FE ports and 2 GE port, and 1 TS in from an USB disk.After multiplexing, scrambling(for 5*DVB-C only) and modulating process, it gives 5/8/12 DVB-C or DVB-T (developing) carriers output through one RF output interface.
