Research And Design Of DVB+OTT Platform Based On Catv Network

With adaptive bitrate streaming feature, HTTP Live Adaptive Streaming, dynamic coding technology matures, the Internet television has been extraordinarily rapid development. Internet TV content-rich, independent and strong, interactive, excellent service, from space, time constraints, etc. more and more customers, subscribers increased year by year trend.
