Abstract: A system and method are provided for providing both static and dynamic IP multicasting. When a router receives a PIM message or an IGMP message, the router determines whether the group specified in the message is within the multicast Static-Range. If the group pertains to a static multicasting group, the router does not propagate the message to upstream routers and only connects or disconnects interfaces internal to the router. If the multicast group address in the message is not within the multicast Static-Range, the router implements PIM or IGMP protocols. If the invention is used for broadcasting TV, the low end of TB channels or commonly used channels can be created as static IP multicast. This way, a user can access or leave such channels without an entire shortest path tree being created or torn down, improving access time and channel surfing for a user.

Abstract: An initiating viewer identifies a multimedia channel and submits a request to share the multimedia channel with at least one recipient viewer at another viewer premises. This request is processed by the multimedia receiver of the initiating viewer so as to generate a channel change request for submission to a service provider. In response to the channel share request, the service provider queries the recipient viewer to determine whether the recipient viewer accepts or rejects the offered multimedia channel. If the recipient viewer accepts the multimedia channel, the multimedia channel can be provided to the multimedia receiver of the recipient viewer either for storage for later playback or for immediate playback concurrent with the provision of the multimedia channel to the initiating viewer. Billing for costs associated with the shared multimedia channel is conducted based on billing feedback provided by the initiating viewer.

Abstract: Logical content is defined by start/end times into a VoD media offering. The calculation of byte-range markers corresponding to the start/end times is distributed among the STBs to first request the particular logical content. Upon receiving an initial request for a logical content offering, an IPTV AS returns a VoD media file URL, start/end times, and null values of byte-range markers corresponding to the start/end times. In response to the null values, the initially-requesting STB downloads the entire VoD media file from a Download Media Server, and calculates the byte-range markers by comparing the start/end times to timestamps in non-encrypted headers in the VoD media file. The non-null byte-range markers are transmitted back to the IPTV AS, which provides them to STBs subsequently requesting the same logical content. The subsequently-requesting STBs may download only the logical content by providing the non-null byte-range markers to the Download Media Server.

Abstract: A technique for managing the distribution of digital video content to multiple end-user devices is disclosed. The technique involves statistically multiplexing multiple VBR encoded video streams into an access channel, such as a data over cable service interface specifications (DOCSIS) bonded group, and utilizing quality of service capabilities of an edge device, such as a cable modem termination system (CMTS) or an edge quadrature amplitude modulation (QAM) device, to buffer and schedule IP packets, which carry the VBR encoded video streams, so that packets are not dropped during periods of congestion. Utilizing the quality of service capabilities of an edge device makes it possible to statistically multiplex VBR encoded video streams in a narrowcast application such as Video on Demand (VOD) or Switched Digital Video (SDV) while eliminating the need for process intensive transrating/transcoding operations.

Abstract: As additional channels are added to a communication system for applications, such as standard density (SD) and eventually high density (HD) Video on Demand (VOD), additional capacity can be realized by reducing the time required to transmit content. A reduction of transmission time (or an increase of the transmission rate) can be achieved by bonding chancels of the communication system. The bonded channels typically provide a statistical multiplexing gain because the additional bandwidth is treated as a large single channel for the download. Bonding channels of the communication system can provide high speed downloading of content, such as video content, far in excess of the playback rate. Using bonded channels can relax the Quality of Service (QoS) requirements of a data stream, such as a video stream, over an internet protocol (IP) network.

After receiving a selection of one URL, the mobile terminal parses the selected URL to retrieve a channel identifier, and automatically switches to a channel corresponding to the channel identifier. The mobile terminal connects to a wireless AP on the channel to retrieve a corresponding type of the multimedia content from the multimedia server.

Abstract: A method and apparatus for identifying an appropriate video signal path is provided for delivery of video-on-demand (VOD) data to a subscriber in a VOD system. The signal path may be a portion of an hybrid fiber optic and cable (HFC) network so that other signal paths in the HFC network may service subscribers in other areas. Because each path need not service every area, the total bandwidth provided by the VOD server need not be provided to every area so that the bandwidth provided to each area can be commensurate with the needs of that area. When a subscriber requests VOD programming, the identification received by the subscriber's terminal from the VOD server is returned to the server along with the request. From the identification, the VOD server may determine the area in which the requesting subscriber is located and the VOD server may then transmit the requested programming to the area in which the subscriber is located for reception by the subscriber.
