Method and system for staggered statistical multiplexing

摘要

In a multi-channel video transmission system in which channel video segments are operated on by corresponding channel video encoders to encode the video segments into frames organized into groups of defined frame types, an apparatus and method to cause a temporal staggering for the processing of a specific frame type among the various channels. In one preferred embodiment, the apparatus includes a frame counter to synchronize reset signals associated with the corresponding channel video encoders and a means for providing a timing offset to channel video encoders corresponding to a selected frame stagger for a particular corresponding channel.

1. In a multi-channel video transmission system in which video segments are encoded into a plurality of frames organized into frame groups having a structure of a sequence of different frame types, a method for arranging frame transmission alignment among a plurality of channels concurrently transmitted via a common transmission medium, the method comprising:
identifying a specified frame type in each of said plurality of channels; and causing ones of said specified frame type to be arranged so as to avoid temporal alignment with other ones of said specified frame type in corresponding other ones of said plurality of channels, wherein in each channel each video segment comprises a same length of the frame group and each frame group comprises the same sequence of different frame types.
