Abstract
A method for unscrambling a multiplicity of television channels, comprises: receiving a first request for a first channel; receiving a first code for the first channel; extracting and demuxing the first channel from a plurality of channels, using the first code; receiving a second request for a second channel; receiving a second code for the second channel; and extracting and demuxing the second channel from the plurality of channels, using the second code, where the extractions of the first channel and the second channel are performed simultaneously. The method further comprises: providing a first video stream corresponding to the first channel, the first video stream being transcoded, transrated, and multiplexed with a first advertisement; and providing a second video stream corresponding to the second channel, the second video stream being transcoded, transrated, and multiplexed with a second advertisement.
