    摘要: A video data transmission method and apparatus for transmitting video encoded data with intra-coded video data portions therein suitable for selective high speed reproduction. A first entry point is detected in the encoded data which corresponds to the position of a first intra-coded video data portion. At least one packet is generated on the basis of the decoded first entry point that includes position information relating to at least one second entry point and at least one additional information relating to the video encoded data. The second entry point exists in a forward direction or in a backward direction relative to the first entry point and corresponds to position of at least one second intra-coded video data portion. The packet is multiplexed at a predetermined position of the video encoded data, wherein the multiplexed video encoded data is suitable for selective high speed reproduction of the intra-coded video data portions.

    摘要: A data demultiplexer for separating multiplex data including at least coded video data, coded audio data, timing data indicative of a video decoding start time, timing data indicative of an audio decoding start time, and timing data indicative of a system clock reference time. The demultiplexer comprises a circuit for separating the multiplex data into the component data, and comparators for comparing input data with the reference timing data. When the timing data indicative of a video decoding start time is inputted and detected, the video data is written in a video code buffer at the maximum transfer rate. During such time period, the reference timing data indicative of the current time is monitored, and the operation of decoding the video data is started when the reference timing data has become equal to the video timing data. A similar operation is performed with regard to the audio data as well, so that the video and audio data can be inputted fast to consequently enhance the responsivity at the start of reproduction.

    摘要: A data recording method is provided in which video data and plural channels of language data are divided into packets as units, and the video data and the plural channels of language data are recorded on a record medium along with the control information containing a flag designating a reproducing channel of the language data matched to a reproducing pattern of the video data. Thus it becomes possible to record video data and plural channels of language data on a record medium so that a reproducing channel for the language data matched to the reproducing pattern of the video data will be selected and the plural channels of language data matched to the reproducing pattern and the video data will be reproduced by a reproducing system.
