摘要： A video signal input-output circuit and a recording-reproduction apparatus in which a digitally compressed video signal input in packet form can be recorded and reproduced efficiently and in stable fashion. In this apparatus, a clock reference is detected from a packet signal containing the clock reference and a digitally compressed video signal, a time stamp for a packet is generated using a clock signal in phase with the clock reference and added to the particular packet, and the packet signals with the time stamp added thereto are recorded closely to each other in a data storage element such as a magnetic recording medium. At playback, the packet interval is output by being restored to the original length on the basis of the time stamp added to the packet in store.

摘要： A method of transmitting timing critical data via an asynchronous channel without changing any datum to be transmitted. The timing critical data can be an MPEG transport stream. The asynchronous channel can be a computer or telephone network, a digital storage media such as a digital VCR, or a digital interface. The method involves tagging each transmission unit of the data stream, before inputting to the channel, with timing information, and using the timing information at the output end of the channel to recreate the proper data timing. Various schemes are described for packing the timing information tags with each or a plurality of transmission units.

摘要： A recording apparatus, a recording method, and a recording medium, which allows a search operation based on a second segment information signal representing finely divided segments of a recording signal even in a player which can perform only a searching operation of a first segment information signal representing large segments of the recording signal. When a change of the second segment information signal of a signal to be recorded is detected, the first segment information signal being formed is updated and the first segment information signal is recorded together with an audio signal. That is, the second segment information signal of the signal to be recorded is converted into the first segment information signal and recorded together with the audio signal.

摘要： When a recording condition judgement section (28) determines a recording condition of the recording of data onto a disk, and the recording is discontinued in response to the decision, a recording speed setting section (29) switches a recording speed to a speed one step slower than the previous recording speed. With this arrangement, when the recording condition is inferior, the recording is discontinued to thereby avoid a recording failure. Moreover, the recording speed is corrected stepwisely so that a disk adaptable recording speed can be set. Further, a recording start position at which to start additional writing is detected by the recording start position detection section (26), and the recording data is synchronized with the recording data by a synchronism setting section (27) to ensure successiveness before and after the recording data connection due to additional writing to the disk, before the recording is resumed
