Multimedia Application WCDMA in Video Processing (Video Codec)
This note is intended to show an example of the implementation of a wireless video codec (encoder and decoder) that includes pre-processing of the captured data to interface with the encoder and post-processing of the data to interface with the LCD panel. The video codec is compliant with the low bit rate codec for multimedia telephony defined by the Third Generation Partnership Project (3GPP) in the specifications 3G TS 26.110, 3G TS26.111 and Recommendation 3G TR 26.911.
The baseline CODEC defined by 3GPP is H.263 and MPEG-4 Simple Visual Profile is defined as an optional. The video codec implemented supports the following video formats.
SQCIF or 128 x 96 resolution
QCIF or 176 x 144 resolution at Simple Profile Level 1
CIF or 352 x 288 resolution at Simple Profile Level 2
64 kbits/s for Simple Profile Level 1
128 kbits/s for Simple Profile Level 2
