摘要： When a packet data is transmitted, a sync pattern comprising ‘q’ words (‘q’=m+n) is added to the data. The ‘q’ words is formed by combining a fixed pattern comprising ‘m’ words (‘m’ is an integer greater than 0) with plural types of variable patterns each comprising ‘n’ words (‘n’ is an integer greater than 1). In this case, a bit structure included in at least two consecutive packets should include different types of variable patterns.

摘要： A transmitting method serializes two series of signals into one series of signals, and transmits thereof. The two series of signals are produced through this way: a total number of bits of a luminance signal of an HDTV signal to be transmitted within a frame is divided into units corresponding to a total number of scanning lines ‘K’ per frame of one channel of an SDTV signal. Then K pcs. of transmission units per frame including a luminance signal and a color signal are produced in two series. Among the transmission units, at least the following data are inserted into the units corresponding to active scanning lines: (a) a given word of the control signal, (b) a signal comprising samples of N timed by a number of words of luminance signal within a given period of one horizontal scanning period of the SDTV, which includes a luminance signal and color signal of the SDTV, and (c) words corresponding to a given level. A transmitter realizing this method is also provided. A receiver and a receiving method automatically detect the source format of the video signal transmitted through the transmitting method using a digital sync signal and a line number. These receiver and method of receiving are also provided.

摘要： Disclosed is a digital data transmission system comprising a transmission apparatus and a reception apparatus. The transmission apparatus generates error location information at which an error occurs in each block, in accordance with a data signal including a video signal composed of a first number of words and generated for each block, and an error information signal indicating presence or absence of an error corresponding to the data signal, multiplexes the generated error location information and the data signal into a multiplexed signal, and then, transmits the multiplexed signal through a transmission line. On the other hand, the reception apparatus receives, through the transmission line, a transmission data signal including a data signal including a video signal composed of a predetermined first number of words and generated for each block and an error pointer signal indicating error location information corresponding to the data signal, demultiplexes the received transmission data signal into the data signal and the error pointer signal, and generates error information indicating presence or absence of the error corresponding to the data signal, in accordance with the error pointer signal. The data signal is decompressed in accordance with the generated error information, and this leads to reduction of occurrence of errors.

摘要： A standard reproduction model for ensuring real time reproducing on a disk-shaped information recording medium, includes a pickup (102) that reads the real time data from the information recording medium, a buffer memory (103) that temporarily stores the real time data read by the pickup, and a decoding module (104) that reads the real time data from the buffer memory (103) and processes the read real time data. An access time Tacc of the standard reproduction model is expressed by the following formula, Tacc=A·dN+Trev+B where dN is a difference in rotational speed of the disk-shaped information recording medium, Trev is a rotation waiting time at a target access position, A and B are constants.

摘要： A number of outer parities to be added to an audio data is changed responsive to a ratio of frame frequencies of a video signal (e.g. 24 Hz or 30 Hz) before the data is recorded. Comparing with a first format, a recording bit rate is increased in a second format. Audio 4 channels (audio sectors 5-8) are additionally recorded maintaining a video data format (video sectors 1, 2) of the first format and an audio data format (audio sectors 1-4) of the first format.

摘要： To improve the convenience of a record medium and allow a reproduction process to be more easily performed than before. When a reproduction process 123 that reproduces material data recorded on a disc 32 is executed, a disc information file management section 63 references a reproduction history of a disc information file held in a disc information file hold section 52 and starts reproducing material data from a position according to the reproduction history. When the reproduction process is completed, the disc information file management section 63 updates the reproduction history of the disc information file held in the disc information file hold section 52. A disc information file record control section 82 records the updated disc information file on the disc 32.
