摘要： In a high definition television system (HDTV), a video signal is recorded on and reproduced from oblique and successive parallel tracks on a magnetic tape, and an audio signal is recorded on and reproduced from a plurality of parallel tracks extending in a longitudinal direction of the tape. The tape is transported in its longitudinal direction during recording and reproduction. A tape position adjuster adjusts the position of the magnetic tape in its transport direction, and first and second transducing heads located at positions separated by a predetermined distance which may vary slightly because of manufacturing tolerances are employed for respectively reproducing and recording the audio signal. When the tape is edited, a processor connected to the first transducing head processes a reproduced audio signal and supplies it to the second transducing head, which records it accordingly. A controller responsive to an output signal of the adjuster controls the processor so as to shift the recording timing of the second transducing head as may be necessary to prevent the accumulation of recording timing errors during successive edits of the tape.

摘要： In a method for recording and/or reproducing digital data, such as digital audio signals recorded simultaneously with video signals, dividing sampling data composed of a plurality of bits into higher order bits and lower order bits, constituting error correction coding blocks by only the higher and lower order bits of the sampling data of a plurality of samples respectively, thereby making it possible to easily realize adaptive error checking in the course of the block-by-block error checking in association with, for example, data criticality.A sync word and a block address are affixed to the error correction coding block constituted in that manner. Since one block address is formed using the address data of two or more blocks, a broader address space can be obtained even when the bit number of the address area of each block is few. At least one flag bit(s) are provided in each sync word to use said flag bits in the blocks bearing specified block addresses as edit flags to set the edit flags in association with each edit point of digital signals, thereby facilitating discrimination of the editing points to reduce the rate of data discarding.
摘要翻译：在用于记录和/或再现与视频信号同时记录的数字音频信号的数字数据的方法中，将由多个比特构成的采样数据分成高阶比特和低阶比特，仅构成纠错编码块和多个样本的采样数据的低位比特，从而使得可以在与例如数据临界性相关联的逐块错误检查的过程中容易地实现自适应错误检查。同步字和块地址被附加到以这种方式构成的纠错编码块。由于使用两个或更多个块的地址数据形成一个块地址，所以即使当每个块的地址区的位数很少时，也可以获得更宽的地址空间。在每个同步字中提供至少一个标志位以使用具有指定块地址的块中的所述标志位作为编辑标记来设置与数字信号的每个编辑点相关联的编辑标志，从而便于识别编辑指向降低数据丢弃率。

摘要： A line number LN is extracted from serial data corresponding to BTA S-004 standard. The line number LN is placed as LN0 and LN1 to each of a luminance signal Y and color difference signals Pr/Pb of a 4:2:2 signal. The 4:2:2 signal is converted into a 3:1:1 signal by a bandwidth-compressing means. In addition, the 3:1:1 signal is re-arranged to two-channel signals Ch0 and Ch1 with the same format at a transmission rate of 46.40625 MHz. Thereafter, the, signals are processed at the transmission rate of 46.40625. The line number LN is placed as LN0 and LN1 at the beginning of one horizontal interval.

摘要： Reproducing heads reproduce signals from a tape in advance of recording heads for a time period equivalent to a system delay. An ECC decoder corrects an error of a signal received from each reproducing head. A BRR decoder decompresses and decodes the signal received from the ECC decoder. A concealing circuit interpolates the signal received from the BRR decoder. An output signal of the concealing circuit is sent back to a selector of the recording system. The selector switches between a signal received from an input terminal and the reproduced signal at the end of each field. An intra-field encoding process or an intra-frame encoding process can be selected as an compressing and encoding process. Information that represents the selected encoding process is recorded on the tape.

摘要： A digital audio and video signal recording system and method wherein erasure of a channel has no major effect on adjoining audio signals in the case of high density recording. The same channel of audio signals are recorded arranged in blocks in a direction orthogonal to the helical track of the magnetic tape. There is a possibility of the occurrence of error at the two outside tracks due to narrowing of the tracks at the time of editing of a channel, but preferably an outer code is added to enable erasure correction.

摘要： In a time base corrector incorporated in a VTR, if a time during which a vertical synchronizing signal is written in a memory unit exceeds one horizontal period segment, the video signal stored at the first address of the memory unit is dropped out during data reading operation. To overcome the above problem, a write address designation signal is initially latched in response to a vertical synchronizing signal; a predetermined number is subtracted from the latched address number; the subtracted address number is loaded in a counter in response to a reference vertical synchronizing signal and is incremented in response to a reference horizontal synchronizing signal in order to shift the read start address, thus preventing video signals stored in the memory unit from being dropped off.

摘要： An industrial X-ray tube formed by accommodating a cathode and anode in a container having an evacuated interior, in which electrons emitted from the cathode are caused to strike the anode and X-rays are emitted from the anode. The cathode is formed from graphite. The graphite is a layered crystal obtained by layering a plurality of carbon hexagonal planes. The graphite is cut based on crystal axes of the carbon hexagonal planes. The resulting cut surface is caused to function as an electron-emitting surface. For example, directions of an a- and b-crystal axis may be set so as to be arbitrary between each of the layers of the carbon hexagonal planes, the graphite may be cut along a surface parallel to the c-axis, and the resulting cut surface may be caused to function as an electron-emitting surface. The graphite may also be cut along a surface orthogonal to the c-axis.
