摘要： A slow decode control part divides a reference clock generated by a VCXO at a ratio of a slow speed to a normal speed. An STC circuit counts the divided clock. A time for starting decoding by an MPEG video decode part is decided by comparing a DTS included in MPEG data with the count of the STC circuit. A display time determination part determines a timing for outputting decoded data by comparing a PTS included in the MPEG data with the count of the STC circuit. Decoded data temporarily held in a frame buffer is output in response to a signal generated in a determination part on the basis of frame frequency information included in the MPEG data. Thus, slow reproduction is implemented with a high degree of freedom not limited to an integer-fractional speed without requiring a complicated circuit structure.

摘要： In a communication system in which a transmitting device transmits a video signal to a receiving device, one or both of these devices includes a beacon analyzer that analyzes beacon signals transmitted by other wireless systems operating in the same frequency band and predicts periods during which beacon transmission is expected. During these predicted periods, video transmission is suspended and the video signal is stored in a buffer in the transmitting device. At the end of each predicted period, the stored video signal is read from the buffer and transmitted without horizontal and vertical blanking periods until the buffering delay is made up. The receiving device displays the received video signal with standard video timing. A normal unbroken video picture is thereby obtained despite beacon interference.
