Appeal No. 2003-2057
Application No. 09/201,865
BACKGROUND
The invention relates to video coding-decoding (CODEC) method and apparatus
that, according to appellants, provide greater resilience against channel error in
comparison with the prior art. Representative claim 1 is reproduced below.
1. A video coding-decoding (CODEC) method for coding video data to
generate a video data packet and for decoding the packet, comprising the steps
of:
(a) partitioning a header data part (HDP) bit region, a motion vector data
part (MVDP) bit region and a discrete cosine transform data part (DDP) bit region
from each macro block of the video data in an error resilient mode;
(b) variable-length-coding the partitioned bit regions;
(c) reversible-variable-length-coding the bit regions selected from the
variable-length coded bit regions according to a predetermined priority for
recovery; and
(d) inserting markers into the variable-length coded or
reversible-variable-length-coded bit regions.
The examiner relies on the following reference:
