  • Patent number: 8544051
    Abstract: Methods and apparatus are disclosed for offering broadcast IPTV solutions over cable (HFC networks). Rather than bypass the CMTS, a reduced number of downstream ports are utilized for video streams. Each input video stream is streamed to a multicast group address. In one embodiment, several RF channels are configured so that they are RF spanned across all the Fibernodes in the CMTS service area. In an embodiment, an STB sends a service request for a desired video stream using an IGMP request, and the CMTS responds by issuing a DBC request to tune the corresponding CM to the RF channel that is carrying the requested stream. Preferably, the CMTS ports that carry the static multicast streams are RF spanned across all the Fibernodes, or a selected subset.
