HYBRID MPEG/IP DIGITAL CABLE GATEWAY DEVICE AND ARCHITECTURE ASSOCIATED THEREWITH |
摘要 |
A novel cable gateway system and architecture incorporating a hybrid digital video transceiver. The digital cable system architecture combines reception of legacy video such as MPEG-TS based DVB-C streams with that of original IP video over DOCSIS channels. The system comprises a hybrid DVB/IP cable gateway STB capable of receiving both legacy DVB-C video and original IP video streams. The cable gateway device performs the front-end functionality (including QAM receiver, tuner and broadband connection) while the back-end functionality of video decoding and display is performed by one or more standard IP-STBs connected to the cable gateway device over a network (e.g., home LAN). Legacy MPEG-TS based DVB-C video is captured and encapsulated into packets for distribution over the network to the IP-STBs. The cable gateway distributes the original IP video received over the CATV source and the encapsulated legacy video as video over IP packets over the network. |
