A 3G video phone solution for mosaic fast recovery
Gao Yongqing, Chunlai Zhou, Ping Yucai · 2010
This paper analyzes the causes leading to mosaic phenomena for current 3G video phone. A 3G video phone solution for mosaic fast recovery is proposed. The solution proposed in this work mainly consists of software components, according to which hardware needs to be selected. It also gives the video phone terminal structure, block diagram for H.324 M video phone terminal, the main software functional blocks and the overall work flow chart of the designed solution. The mosaic phenomena of video phone is fast restored by adding user interface module, encoding quality control module, decoder reporting & processing module. As well as by the use of software enabling video decoder to dynamically send I-frames of the algorithm according to current decoding status.
