Patent ID: 8917776

Claim:
A computer-implemented method of determining, in an encoder, a bit rate for use in encoding video data for joint decoding, said method comprising: generating an approximation of the video data as frequency coefficients by compressing the video data for later use as side information during a process of joint decoding; determining, in the encoder, a bit error probability for a bit plane of the approximation; determining, in the encoder, a conservative bit rate and a minimum bit rate, each of the bit rates being determined according to the determined bit error probability; and selecting, in the encoder, either the conservative bit rate or the minimum bit rate as the bit rate for encoding the bit plane in accordance with an importance of a frequency coefficient band of the frequency coefficients of the approximation, the determined bit rate being stored in a computer-readable medium, wherein the conservative and minimum bit rates each represent an amount of parity bits for use in decoding the encoded bit plane, the conservative bit rate representing a larger amount of parity bits as compared to the minimum bit rate.
