Abstract

Stereoscopic video coding research has received
considerable interest over the past decade as many 3D
displays have been developed. Unfortunately, the vast amount
of multimedia content needed to transmit or store a stereo
image pair or video sequence has hindered its use in
commercial applications. As H.264 offers significantly
enhanced compression and a “network-friendly” feature, we
have used a H.264 compliant stereoscopic video codec [9] to
compress stereo video. The data partitioning (DP) mode in
NAL unit of the H.264 codec is exploited for the use of joint
source and channel coding (JSCC) taking channel qualities
and reliabilities into account. In this paper, we propose a
framework of using unequal error protection (UEP) based
JSCC scheme on the H.264 compliant stereoscopic video
transmission for additive white Gaussian noise (AWGN)
channel. Different levels of error protection are assigned to
different partitions based on their decoding importance.
Performance comparisons are made against equal error
protection (EEP) schemes. Results from the simulation show
that using UEP schemes, the overall quality of the decoded
main and auxiliary video sequence were clearly improved in
comparison with the EEP scheme at good SNR but EEP
schemes outperformed UEP schemes at low SNR values.
