摘要： PROBLEM TO BE SOLVED: To provide a radio communication system that can stably transmit and receive a signal, and a transmitter and a receiver which can achieve the radio communication system.
SOLUTION: A video signal transmitter 2 constituting the radio communication system is provided with a transmitting side beacon receiving part 12, a self-machine reception beacon analyzing part 13 and a transmission output level changing part 14. When the transmitting side beacon receiving part 12 receives a radio LAN beacon signal that is periodically transmitted at the same frequency band as a radio frequency band used when the transmitting side communication part 11 transmits a video signal, the self-machine reception beacon analyzing part 13 analyzes the radio LAN beacon signal and acquires beacon period information. The transmission output level changing part 14 estimates a transmission period of the radio LAN beacon signal on the basis of the beacon period information and receiving time information of the beacon signal, and increases a transmission output level to instruct the transmitting side communication part 11 to transmit the video signal during the transmission period.

摘要： PROBLEM TO BE SOLVED: To provide an MPEG recording/reproducing apparatus whereby the conveniences of the viewers of a program present in the course of its reproduction can be so improved that the associative pieces of information with the program can be given necessarily to the viewers at least in some form. SOLUTION: In the MPEG recording/reproducing apparatus, when recording its MPEG data, the associative pieces of information with a program are so collected and processed that a program-information collecting unit 14 changes the collection methods of the associative pieces of information in response to the inputted routes of the MPEG data. The associative pieces of information with the program which are obtained thereby are so recorded as to be disposed in the different locations from the ones of the recorded MPEG data wherein the former and latter are recorded on the same track. When reproducing the recorded associative pieces of information with the program, they are so outputted as to superimpose them on the analog video signals subjected-off to MPEG decodings.

摘要： PROBLEM TO BE SOLVED: To provide flexible reproduction in slow motion not to be limited to speed divided by integer without requiring complicated circuit structure. SOLUTION: A slow decoding control part 12b divides a reference clock generated by a VCXO 12a according to ratio of slow speed to normal speed. A STC circuit 9 counts divided clock. Start time of decoding by a MPEG video decoding part 10a is determined by comparison DTS included in a MPEG data with a count value by the STC circuit 9. A displayed time determining part 11a determines when a decoded data is outputted according to comparison between PTS included in the MPEG data and the count value by the STC circuit 9. The decoded data is stored on a frame buffer 19 temporarily and outputted in response to a signal from a determining part 16a according to information of frame frequency included the MPEG data.

摘要： PROBLEM TO BE SOLVED: To resolve such a problem that special reproduction is not realized only by data which is encoded by inter-frame prediction since a special reproducing method or picture quality are greatly different in between two cases, i.e., when data to be sued as special reproduction data is encoded without using inter-frame prediction and when the data is encoded by inter-frame prediction. SOLUTION: Data obtained by encoding compression animation data without using inter-frame prediction and data encoded by inter-frame prediction are recorded as a special reproduction digital signal together. One of data encoded without using inter-frame prediction for the case of speed change reproduction and data encoded by inter-frame prediction is selected. Then it is recorded by multiplexing with normal data so as to be recorded at a fixed position in a direction along a recording rack on a recording medium.

摘要： PROBLEM TO BE SOLVED: To provide a satellite broadcast receiver equipped with a means for estimating a change factor of the reception environment and informing the riceaeer of it when a change occurs in the receiving conditions. SOLUTION: A received power discrimination part 4 detects a received power of a reception carrier, a peak detection part 12 detects and stores a peak value of the received power. Then, in an environment change estimation part 13, the peak value stored in the peak detection part 12 is compared with a present received power detected by the received power discrimination part 4. When the present received power is dropped and the difference between the peak value and the present received power exceeds a threshold, it is estimated that reception environments have changed, and the audience is informed by the environment change estimation part 13 or by using a video and/or a voice.
