Proxy-based error tracking for real-time video transmission in mobile environments
First Claim
1. A method for error tracking in wireless video communication comprising:
- sending a main video stream to an intermediate network node;
sending a side information of video stream to the same intermediate network node; and
performing the function of the requested error correction in the intermediate network node.

Abstract
This invention provides an efficient method of error tracking which quickly recovers the error packet of data. A side information is sent along with a normal video stream that can be used by an intermediate network node in order to improve the quality of the video transmission. The intermediate node receives the original video stream as well as the side information and uses the side information to reduce the error propagation. The error tracking is signaled from the intermediate node to the mobile phone device and the intermediate network node functions the error correction. The side information can then be used to refresh or update those areas that are affected by error concealment and error propagation.

10. A method of error tracking in error correction comprising:
-
a node of video stream is connected by a wired Internet node;
another node of video stream is connected by a wireless mobile Internet;
sending a main video stream; and
sending a side information to the same intermediate node which is a second bit-stream that encodes Macroblocks with respect to a different reference frame. - View Dependent Claims (11, 12, 13, 14)
