Abstract
A method, system and apparatus for improving network transmission efficiency using MDS and Fine Granular Spatial coding is disclosed. In accordance with the method, a video image is partitioned into a plurality of information item frames, each frame is independently layer encoded into a base layer and an enhancement layer, at least one channel of the communication is then selected, each of the base layers are associated with one of the selected communication channels, and each base layer is transmitted over the associated communication channel. In other aspect, a residual bandwidth is determined on each associated channel and a level of an associated enhancement layer comparable to the residual bandwidth is transmitted over the associated channel.
Claims17
A method for improving transmission efficiency of video images over a network having a plurality of communication channels, comprising:
- encoding each information item frame of the video images using layered encoding, wherein said each information item frame is encoded into a base layer and an enhancement layer;
- associating a first base layer with at least a first communication channel of the plurality of communication channels;
- associating a second base layer with at least a second communication channel of the plurality of communication channels, the second communication channel being different from the first communication channel;
- and
- transmitting the first and second base layers over the associated communication channels.
A system for improving transmission efficiency of video images over a network having a plurality of communication channels, comprising:
- a transmitter that is configured to transmit information items over at least a first and second communication channel, the transmitter including at least one processor in communication with a memory that is configured to execute code for:
- encoding each frame of information items of the video images using layered encoding, wherein each of said information item frames is encoded into a base layer and an enhancement layer;
- associating at least one base layer with the first communication channel, and at least one other base layer with the second communication channel;
- and
- transmitting the base layers over the associated communication channels.
A method for improving transmission efficiency of video images over a network having at least one communication channel, comprising:
- partitioning each of the video images into a plurality of information item frames corresponding to predefined areas of the video images;
- encoding each of said information item frames using layered encoding, wherein each of said frames is encoded into a base layer and an enhancement layer;
- selecting at least one of the at least one communication channels;
- associating each of the base layers with at least one of the selected at least one communication channels;
- and
- transmitting the base layers over the associated communication channel.
