Cable

Cable On Demand Solution

There are different ways to design a VOD solution for cable which supports a DOCSIS1/3 based broadband connection to hybrid STBs with a DVB-C connection for digital broadcast MPEG2/4 video and either having a built in DOCSIS1/3 modem or external modem with an Ethernet connection.

In smaller cable networks it can be possible to run the IP VOD traffic within the DOCSIS network. In this perspective the VOD solution is then very similar to the above "Classic" IPTV solution with the main difference being the broadcast traffic which would be running separately over DVB-C. In larger cable networks this architecture would not scale and therefore the fibre backbone of the cable networks would possibly need to be extended in order to have QAM capacity/channels available for VOD traffic to run on DVB-C. The Quative SDP platform supports a Session Resource Manager which then brokers between an on demand IP video server connection and a free QAM port on a case by case bases. This would allow to divert the VOD traffic from the limited DOCSIS IP network capacity out band into the DVB-C network and keep the low bandwidth VOD control traffic (e.g. RTSP for trick play), VOD catalog data download and application traffic such as VOD purchase transactions in band within the DOCSIS network.
