  • receiving, at a television tuner in a serving node, said single wide band signal, a plurality of channels contained within said single wide band signal, each of said plurality of channels differentiated by a code, said code received at said television tuner from a video stream source, said television tuner in said serving node further configured to obtain said codes on request for each of said plurality of channels, said serving node further having a database;

    receiving a first request from a first user device for a first channel among the plurality of channels, said first user device in connection with said serving node over a first network connection, said serving node having a database containing information about a display capability of said first user device;

    receiving a first code for said requested first channel and said television tuner is using said first code to extract and demux said requested first channel from said plurality of channels for transmission via a first video stream to said first user device from said serving node;

    receiving a second request from a second user device for a second channel among the plurality of channels, said second user device in connection with said serving node over a second network connection, the database containing information about a display capability of said second user device;

    receiving a second code for said requested second channel and said television tuner is using said second code to extract and demux said requested second channel from said plurality of channels for transmission via a second video stream to said second user device from said serving node, wherein extraction of said requested first channel and said requested second channel from said plurality of channels is performed simultaneously by said television tuner; and

    providing the first video stream corresponding to said requested first channel to said first user device, said first video stream transcoded for said first user device based on the display capability of said first user device, transrated based on a type of said first network connection, and multiplexed with a first advertisement, and providing the second video stream corresponding to said requested second channel to said second user device, said second video stream transcoded for said second user device based on the display capability of said second user device, transrated based on a type of said second network connection, and multiplexed with a second advertisement.
