Method, apparatus, and system for encoding and decoding side information for multimedia transmission
First Claim
1. A method comprising:
- encoding input data in accordance with a first encoding standard to generate encoded data;
encoding the input data based on a reconstruction of the input data to generate encoded side data; and
transmitting the encoded data over a first channel and the encoded side data over a second channel to a destination.

Abstract
According to one aspect of the present invention, a method and apparatus is provided in which input data (e.g., input video data) is encoded in accordance with a first coding standard (e.g., MPEG-4) to generate encoded data. The input data is also encoded based on a reconstruction of the input data to generate encoded side information associated with the input data. The encoded data are transmitted to a destination (e.g., a decoding subsystem) over a first channel and the encoded side information are transmitted to the destination over a second channel. The encoded data and the encoded side information are decoded and combined at the destination to generate output data.
