| | | Abstract
The latest video coding standard H.264 has been recently approved
and has already been adopted for numerous applications including
HD-DVD and satellite broadcast. To allow interconnectivity between
different applications using H.264, transcoding will be a key factor.
This paper assesses the existing requantization techniques developed
for previous MPEG standards once adapted to H.264 together with
a new technique. The proposed transcoding algorithm is based on
a mixed requantization technique which gives a good compromise between
complexity and quality. Those tests were used to define a plausible
approach for a consumer-oriented transcoder. |
