Claims
- 1. In a cable television network system, said system including a cable head end comprising a system using memory, said memory comprising:
a first code directed to receiving a first constant bit rate stream comprising a plurality of variable bit rate streams, each of said variable bit rate streams corresponding to a program; a second code directed to removing one or more of said variable bit rate streams from said first constant bit rate stream; and a third code directed to transferring said first constant bit rate stream without said one or more variable bit rate streams as a second constant bit rate stream to a user location.
- 2. The system of claim 1 further comprising a code directed to inserting one or more second bit rate streams into said first constant bit rate stream to provide said second constant bit rate stream.
- 3. The system of claim 1 wherein said first constant bit rate stream comprises multiple first constant bit rate streams, each of said multiple first constant bit rate streams comprising a plurality of variable bit rate streams.
- 4. The system of claim 1 wherein said user location includes a digital television.
- 5. The system of claim 1 wherein said second constant bit rate stream comprises multiple constant bit rate streams, each of said multiple constant bit rate streams comprising a plurality of variable bit rate streams.
- 6. The system of claim wherein said second constant bit rate stream comprises an MPEG-2 transport bit stream.
- 7. The system of claim 1 wherein said first constant bit rate stream comprises an MPEG-2 transport bit stream.
- 8. The system of claim 1 wherein said cable head end is a digital cable headend.
- 9. The system of claim 1 wherein said second code directed to removing includes a code directed to transcoding said first constant bit rate stream.
- 10. The system of claim 1 wherein said second code directed to removing includes a code directed to remultiplexing to provide said second constant bit rate stream.
- 11. The system of claim 1 wherein said second constant bit rate stream comprises a local channel.
