摘要： A keyless entry system comprising a transmitter and a receiver. The transmitter increases a first number stored in the volatile memory according to rules, and transmits the first number by radio. The receiver receives the first number, and if the first number is greater than a second number stored in a memory, outputs a signal to indicate being authenticated as correct and updates the second number to the first number. Further, each time increase in the first number becomes a multiple of a predetermined number, the transmitter writes into a non-volatile memory a third number equal to the predetermined number plus the first number. When the first number in the volatile memory is erased due to the exchange, etc., of the battery, the transmitter reads out the third number from the non-volatile memory and writes the third number as the first number into the volatile memory.

摘要： When transmitting encoded video data and audio data, a transmitter 201 also transmits a decoding method 107 generated by decoding-method generation means 203. In the case of a receiver 202, decoding control means 111 controls decoding means 208 in accordance with a received decoding method 113 and thereby, decodes video data and audio data 115. Thus, it is unnecessary for the receiver 202 to previously prepare all of a plurality of decoding methods and the transmitter 201 does not need to encode video data or audio data in accordance with the decoding method owned by the receiver 202.

摘要： A image signal processing apparatus and method for static image display are provided. Deformation at an edge of an image can be reduced by eliminating a temporal factor and vertical resolution can be retained even after data supplementation. In the process of compressing and decompressing interlace-scanned image data, one of two fields of a frame is selected by a field selector, image data is supplemented and reproduced based on the selected field data by a supplementor, and image data is outputted as a static image without deformation. As a result, more bits can be allocated for encoding by selecting and compressing one field data only and it leads to a higher quality image display. Furthermore, display deformation can be reduced by supplementing high frequency components as zero in the decompression processing.

摘要： An apparatus serving as a digital videocassette recorder (VCR) for recording analog video and audio signals as digital signals. The apparatus serves also as a digital data storage drive. The digital VCR and the storage drive share common circuitry and a common magnetic recording medium. This reduces the cost and enhances the efficiency at which tracks are used. The apparatus has a large storage capacity. The apparatus divides input digital data into two parts and performs error correction encoding for each of these two data parts to form sync blocks. These sync blocks are recorded in an audio signal recording area and a video signal recording area, respectively, on the recording medium. Error correction codes used during reading of digital data are the same as those used during recording of video and audio signals. The same track structure and the same sync block structure are used for these two modes of operation.

摘要： A pilot signal is superposed and recorded on data at the beginning of each track. The beginning portion of the track is constituted only of codewords having a disparity of each 10 bits which is +2, 0 or -2. Also, the cumulative value of the disparities of every 10 bits may fluctuate in a period coinciding with the period of the pilot signal to be superposed. Therefore, the frequency spectrum in the beginning part of the track has a peak at the frequency of pilot signal, and using this peak as the pilot signal, tracking is controlled during reproduction.

摘要： A data word of 8 bits is code-transformed into a code word of 12 bits, for an 8/12 code which is suitable for high density recording such as d=2 and k=10, two kinds of synchronous pattern which never appear in data can be respectively provided for the video and audio uses while keeping the limitation with respect to d and k. Accordingly, decision error between the video data and audio data resulting from reproducing error can be significantly decreased, leading to an improvement in error probability and yet it is realizable with an extremely practical circuit structure. In addition, a pilot signal can be generated digitally with an extremely simple circuit, being suitable for home-use digital VCRs or the like which requires a stable pilot signal. As a result, the error rate of a super high density recording apparatus such as, for example, a digital VCR can be significantly decreased, and thus, its practical effects are very large.

摘要： A specific section provided in a track is set in a DC free state, and during reproducing, accurate tracking is conducted on the basis of the crosstalk from the pilot tone superposed in the adjacent tracks in this DC free section. Alternatively, a pilot tone is generated only in a specific section provided in the track, and when reproducing, accurate tracking is effected on the basis of the crosstalk of the pilot tone in the tracks adjacent to this section. As a result, the redundancy required for tracking is notably reduced.
摘要翻译：设置在轨道中的特定部分被设置为无DC状态，并且在再现期间，基于来自叠加在该DC自由部分中的相邻轨道中的导频音的串扰进行精确跟踪。或者，仅在轨道中提供的特定部分中产生导频音，并且当再现时，基于与该部分相邻的轨道中的导频音的串扰进行精确跟踪。结果，跟踪所需的冗余显着降低。
