Abstract

The present invention provides computer software or 'codes' for editing a first digital signal such as a constant bit rate digital signal in a cable headend. The invention has memory for storing these codes. These codes include a first code directed to receiving a first constant bit rate information stream, where the first constant bit rate stream is made of at least a plurality of variable bit rate streams. Each of the variable bit rate streams corresponds to a program, e.g., television program. The invention also includes a code that removes one or more of the variable bit rate streams from the first constant bit rate stream, and a code that transfers the first constant bit rate stream, without the one or more variable bit rate streams, as a second constant bit rate stream, which may include an additional television channel, to a user location. These codes can be stored in computer memory including memory of integrated circuit devices.
