    摘要： The video signal input is converted to high-speed reproduction data by a high-speed reproduction data encoder 1. The video signal input is converted to high-speed reproduction data by a formatter 2, which formats the high-speed reproduction data so that the same data is recorded to n tracks. After the recorded data is input to an error correction encoder 3, it is decoded by a decoder 4 and recorded by a recording head 5 to the magnetic tape 6. During reproduction, the recorded data is reproduced by reproduction head 7 from the magnetic tape 6, and decoded by decoder 8. The decoded data is then error corrected by an error correction decoder 9, and then input to a deformatter 10. The deformatter 10 separates the normal reproduction data from the high-speed reproduction data, and separately outputs both data types. During normal reproduction, the normal reproduction data is output by a switch 13; the high-speed reproduction data is decoded to video data by a high-speed reproduction data decoder during high speed reproduction, and output.

    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 data source has a data converting part for converting inputted data to predetermined data packets. A data buffer stores the data packets. A descriptor list stores a descriptor to which predetermined addresses are added, where a method of sending the data packets is described. A FIFO stores the predetermined addresses in a first-in first-out mode. A data sending part receives start instructions from the data converting part, refers to a predetermined address in which reference is not made yet in the FIFO, fetches data packets corresponding to the descriptor from the data buffer in accordance with a method of sending the descriptor indicated by the predetermined address, generates a send packet from the data packet and outputs the data packet. An end-of-send notice to the data converting part is also send when the output of the send packet is ended.

    摘要： In a digital signal recording and reproducing apparatus, digital input data is transmitted in a transmission packet format and is recorded in a recording packet format. In a recording stage, an auxiliary signal generator (3) generates an auxiliary signal for special reproduction in the transmission packet format, and the digital and auxiliary signals are converted into respective recording packets by means of recording signal converters (5, 6). Recording means (9, 10) performs a specific recording process on the recording packets and an identification signal for identifying between the recording packets of the digital signal and of the auxiliary signal. While in a reproducing stage, reproduction signal processing means (14, 15) performs a specific reproduction process on the reproduction signal to thereby reconstruct the recording packets and the identification signal. A packet selector (16) detects the reconstructed identification signal to determine whether the recording packet is of the digital signal or of the auxiliary signal, and then the digital signal or auxiliary signal is reconstructed by a signal reconstructor (17) in the transmission format using the selected recording packet, whereby a high quality image output conforming to the transmission format used in the normal reproductions mode is also obtained during the special reproduction modes.
