摘要： A plurality of digital signals having total data rates of n bit/s or less are input to a digital recording device recording digital signals having a data rate of n bit/s. The digital signals are subjected to format-conversion for the digital recording device to be recorded therein. Furthermore, signals having a data rate of n/i.sub.1 bit/s or less are subjected to format-conversion to be recorded i.sub.1 times in the digital recording device. In the case where the data rate of the digital signals to be input is n/j bit/s, the digital signals are subjected to format-conversion so that the amount of data capable of being recorded per unit time is decreased by i/j; thus, the digital signals are recorded for a long period of time under the condition that the data recording time is prolonged j times. Furthermore, when input data to be recorded on a magnetic tape at a normal data rate by using a magnetic head mounted on a rotary cylinder is recorded, the recording device of the present invention makes it possible to select a plurality of types of track angles generated by the rotation number of the cylinder, the tape traveling speed, and the like.

摘要： A reproduction apparatus is designed to select and decode speech and subtitles (characters) in a given language from a disk on which various types of information are recorded in different languages. This system arrangement makes it possible to standardize the manufacture of disks and reproduction apparatuses world-wide, resulting in a reduction in production cost. In a disk 100, various types of information are recorded in different languages along with video information. A reproduction apparatus selects information in a given language from the reproduced information using a data string processing section 203, a system control section 204, and an operator section 205, and supplies the selected pieces of information to each of a video processing section 206, a subtitle decoder 211, and an audio processing section 213.

摘要： A digital video/audio recording and reproducing apparatus comprising a video signal high-efficiency encoder having a variable reduction rate, an audio signal high-efficiency encoder having a variable reduction rate, and a controller for controlling the reduction rates in both of the high-efficiency encoders. The reduction rates in both of the high-efficiency encoders are controlled in such a manner that the sum of the information amount of the video signal and that of the audio signal, after high-efficiency encoding, is maintained constant. When recording multi-channel audio signals, the reduction rates in both of the high-efficiency encoders are controlled according to the number of audio signal channels to be recorded. The high frequency components of the high-efficiency encoded video and audio signals are recorded at the end portions of recording tracks on a magnetic tape, while the low frequency components thereof are recorded in the central portion of the recording tracks.

摘要： An electronic apparatus wherein a light receiving window is formed in a cabinet for passing therethrough an input command signal supplied from a remote commander to execute various control actions, so that desired operations can be performed by manipulating the remote commander. The window is formed in a blank portion of and/or between characters/figures inscribed on the cabinet or on a logo plate attached to the cabinet. A light sensor or a light emitter is disposed in a stage posterior to the light receiving window. When the apparatus is applied to a television receiver or a projector embedded in a wall by user's customization in a manner that only a display screen and a frame thereof are seen on the wall, the external design is not spoiled while the command signal from the remote commander can still be inputted properly.

摘要： A video recording medium, video signal processor, and method are provided. The video signal processor includes a transcoder for receiving a video input signal comprising a plurality of input signal frames, each of the input signal frames including at least one of intraframe data and interframe data, and for constructing a corresponding plurality of system frames from the input signal frames, each of the system frames having a fixed length and including a first portion, having a first fixed length, including intraframe data and excluding interframe data, and a second portion, having a second fixed length, including interframe data and excluding intraframe data. By using a fixed system frame length, by using fixed lengths for the intraframe and interframe data segments, and by appropriately positioning these segments on respective recording tracks, the recording heads record only intraframe data from the sequential recording tracks as the heads diagonally traverse the tracks along their trick mode head trajectory during trick mode operation. The intraframe data thus read can be used directly to produce a display of a TV image which, although imperfect, is acceptable to the viewer.
