A method, system and devices for delivering a switched digital video (SDV) channel to a network element, such as an end user set-top box, based on the decoding capabilities of the network element. The system determines whether to deliver the SDV channel in a first format, such as MPEG-4, or a second format, such as MPEG-2. When only network elements capable of decoding MPEG-4 content are tuned to the SDV channel, the system can realize bandwidth savings by delivering only the MPEG-4 version of the SDV channel. When legacy network elements capable of decoding only MPEG-2 content tune to a particular SDV channel, the system delivers only the MPEG-2 version of the SDV channel. The methods and devices can be used in headends, including those that deploy switched digital video, and other appropriate locations within the content distribution system, such as within the edge devices in the distribution hub.
A method for providing a switched digital video (SDV) channel of digital content from a content source to at least one service group, wherein the at least one service group includes a plurality of end user network elements, wherein the method comprises the steps of:
A switched digital video (SDV) system, comprising:
A computer readable medium storing instructions that, when executed on a programmed processor, carry out a method for providing a switched digital video (SDV) channel of digital content from a content source to at least one service group, wherein the at least one service group includes a plurality of end user network elements, comprising:
