Appeal No. 2003-2092
Application 09/046,285
accumulated number of the bits reaches the limit. See page 9 of
Appellants’ specification. The VLE unit then discards the
remaining coefficients of the block and finishes its encoding of
the block by outputting an end of block code. See page 10 of
Appellants’ specification.
Independent claim 1, present in the application, is
representative of Appellants’ claimed invention and is reproduced
as follows:
1. A method for encoding digital video picture data,
comprising the steps of:
partitioning the video picture data into a group of blocks;
quantizing the video picture data;
selecting at least some of the blocks, one block at a time;
encoding each of the selected blocks in a variable length
encoder to form encoded coefficients having varying numbers of
bits;
for each of the selected blocks, and in a given sequence of
the selected blocks,
i) transmitting quantized data for the block to the
encoder,
ii) outputting from the variable length encoder the varying
bit coefficients encoded from the block,
iii) accumulating a sum of the number of bits in the varying
bit coefficients output from the encoder,
iv) comparing said sum to a predefined block limit value,
