Apparatus and methods for multi-stage multiplexing in a network |
摘要 |
Methods and apparatus for performing multiplexing of video or other content (e.g., programs) within a network using feed-back from a subsequent digital program insertion stage, and/or feed-forward information from a prior multiplexing stage. In one embodiment, the network comprises a hybrid fiber coax (HFC) cable network having headend and hub-based statistical multiplexing stages, and communication between the two stages is used to improve the visual quality performance and bandwidth utilization of the output multi-program stream during conditions where downstream content is inserted into the transport stream. Business methods associated with the various multiplexing features described above are also disclosed. |
