Abstract: 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.

Abstract: A receiving device (50) is provided to allow appropriate clock regeneration even for a VBR TS when a stream including video and audio data, such as an MPEG2 TS, is transmitted or received in real time through a network having jitter. When the received packet data is stored in a memory (53) and the packet data is output in accordance with time information added to the received packet data, a clock frequency deviation between a sending device and a receiving device is calculated on the basis of the integration result of the amount of the received packets temporarily stored in the memory (53), the number of the received packets which have been processed, and the measurement result of the integration time used for integrating the amount of the received packets. A read timing offset of the received packet is obtained on the basis of the calculation result of the clock frequency deviation.

Abstract: An MPEG recording and playback device is provided which can provide pertinent information on a program being played back to viewers at least in certain forms with certainty, thereby facilitating viewers' convenience. In this MPEG recording and playback device, during recording of MPEG data, a program information collecting unit (14) collects pertinent information on program responsive to an input path of the MPEG data by changing a method of collection, and the pertinent information on program is recorded in a different location of a track from that for the MPEG data. During playback, recorded pertinent information on program is outputted after being superimposed on an MPEG decoded analog image signal.

Abstract: An MPEG data recorder comprises an interface means for receiving a data packet from a digital transmission line transmitting MPEG data in real time, and extracting a predetermined MPEG data from a received packet to output it as a data signal; a data rate detector means for determining a data rate of MPEG data based on a valid data period, during which the data signal is outputted from the interface means; and a recording mode selector means for selecting a recording mode based on the determined data rate. According to such a configuration, the data rate of MPEG data can be detected without a necessity of analyzing the MPEG data, which would require an MPEG system layer decoder, and thereby an MPEG data recorder can be obtained, in which MPEG data are recorded efficiently in a proper recording mode, with a simplified circuit configuration.
