Abstract:
|
The International Telecommunication Union (ITU) approved the multimedia conferencing standard H.324 on March 1996. The Moving Picture Expert Group (MPEG) a working group under International Standard Organization/International Electrotechnical Commission (ISO/IEC) also released its MPEG-4 audio-visual coding standard in 1998. The author presents a general overview of two multimedia standards H.324 and MPEG-4. In addition, GSM High Speed Circuit Switched Data (HSCSD) service and the Wide band Code Division Multiple Access (WCDMA) for the third generation mobile phone systems are discussed to illustrate how mobile video telephony systems work via the network. The author presents H.263 lowbit rate video coding as one main element of the H.324 standard, where the author has implemented and tested the variable length coder and the optional deblocking filter using fixed-point digital signal processor. The testing results, analysis and optimization ideas for the implemented parts are presented. /Kir10 |
