| Abstract: | An effective method was presented to improve dual - mode wireless video transmission of TD - SC- DMA and CDMA20001 x, solving the problem of framing error phenomenon caused by asynchronous receiver of time delay differences when dual - mode wireless video are transmitted and of scheduling problems caused by the inconsistence of dual - mode network bandwidth. The method includes to sign flag on initial terminal for pack preconditioning and to combine synchronous on receiving end. It also designs team working of wire- less communication channels and dispatching management of video data transmission. The software design and implementation of dual - mode wireless video transmission terminal system were introduced. At last, the video compression algorithms and dual -mode wireless video transmission were tested. |
