  • Patent number: 7698728
    Abstract: An automated playlist chaser (APC) improves the recovery time and robustness of playlists to component failures and/or human errors in a content sourcing and editing environment. Following detection and correction of an error in a content sourcing subsystem controlled by a playlist, the APC retrieves a last known good playlist from a playlist archive and automatically builds a new playlist for resynchronization of the subsystem. Building the new playlist involves iteratively solving for the first new program segment entry in the new playlist and the new “on-air time,” “start-of message,” and “duration” attributes for the entry as a function of a reference time (e.g., the present time of day), the original on-air time for the entry, the subsystem recovery time, the APC processing time, and the queuing delay of the audio-video source for the program segment.

    Abstract: One or more upstream line cards each include a digital or analog multiplexer front end circuit for a Cable Modem Termination System. Each upstream line card has only upstream receivers and allows a CMTS to share one or more receiver chips to receive and recover data from a larger number of input cables coupled to the front end multiplexer. A control circuit for the multiplexer uses MAP data and burst assignment data and upstream mini-slot counts for each of the input cables to determine when a burst is about to arrive on a cable and cause appropriate switching by the multiplexer or crossbar switch. In some embodiments, there is only one RF channel circuit coupled to the output of the multiplexer, so the multiplexer is controlled to couple the input cable upon which the burst is expected to the single RF channel.
