Channel adaptive video transmission system for use with layered video coding and methods for use therewith

摘要

A video transmission system includes a transceiver module that transmits a video signal to a remote device over at least one communications channel wherein the video signal is transmitted as at least one separate video layer stream chosen from, an independent video layer stream and at least one dependent video layer streams that require the independent video layer for decoding. A control module determines at least one channel characteristic of the at least one channel and chooses the at least one separate video layer stream based on the at least one channel characteristic of the at least one channel.

主权项

1. A video transmission system comprising:
a transceiver that transmits a video signal to a remote device over a plurality of communication channels; a controller, coupled to the transceiver, that determines at least one channel characteristic of at least one channel of the plurality of communication channels, wherein the controller further selects, based on the at least one channel characteristic of the at least one channel, one of: a first mode of operation, and a second mode of operation; and a video encoder, coupled to the transceiver and the controller, that adaptively encodes the video signal, wherein the video signal includes:
in the first mode of operation, an independent video layer stream; andin the second mode of operation, the independent video layer stream and at least one dependent video layer stream that is dependent upon the independent video layer stream for decoding; wherein the controller selects the first mode of operation when the at least one channel characteristic compares unfavorably to a threshold, and wherein the controller selects the second mode of operation when the at least one channel characteristic compares favorably to the threshold.
