Abstract: When the low bit rate coding is effected in a recording system 1A, a signal is coded and recorded in a hierarchical structure. On the reproduction side, the type of a recorded signal (the low bit rate coded signal of the hierarchical structure, non-hierarchical structure, conventional analog recording or the like) is determined by a determination system 1E and the operation modes of a digital signal processing system 1G and an analog signal processing system 1F are set. The analog signal processing system processes a reproduced signal when it is analog signal. The digital signal processing system processes a reproduced signal when it is a digital signal or when a reproduced output from the analog signal processing system is processed in a digital manner.

Abstract: An apparatus for reproducing image signals has a code arranging device that adds a flag to a data signal so as to produce a coded data signal. The apparatus also has a recording device that records the coded data signal onto the magnetic tape and a reproducing device the reads the magnetic tape and reproduces the coded data signal. In addition, the apparatus has a flag detecting device that detects the flag within the coded data signal. A decoding device is used to decode the coded data signal. The apparatus has a recording position presuming device that presumes a position where intra-frame coded data is recorded on the magnetic tape. A reproducing control device controls the speed at which the reproducing device operates. Further, the apparatus has a device for outputting, at a cycle that is based on a speed multiplying coefficient, a decoded signal, which is based on a reproduced data signal.

Abstract: According to a high efficiency coding signal processing apparatus of the present invention, in order to suppress error propagation, effectively correct errors, and reduce a signal deterioration upon repetitive coding processing, a bit rate reduction circuit quantizes a video signal and outputs the resultant signal to low-and high-frequency encoders. A first transmission sequence packet circuit outputs low-frequency components at a predetermined period. A second transmission sequence packet circuit sequences and outputs high-frequency components. Since the low-frequency components and the high-frequency components are separately sequenced and transmitted, the low-frequency components are free from the influence of errors caused in the high-frequency components.

Abstract: A light transmitting type display plate 5 is arranged above a cell 2 such as an EL element or a solar cell or the like, and the display plate 5 is fixed to the support member 4 through the engagement of a positioning section 5b formed on the light transmitting type display plate 5 with a positioning section 4b formed on a support member 4. In the case where the light transmitting type display plate is a transparent plate 5, a spacer 6 or the like forms a gap 7 between the cell 2 and the transparent plate 5.

Abstract: A digital image signal is coded into an intra-picture component I, a forward predictively component P, and a bidirectionally predictively component B. These components are then time divisionally multiplexed. A process flag is attached to the intra-picture component to identify it, and then recorded. The recorded tape is scanned during reproduction so as to read the coded data at either a normal operating speed or a higher operating speed (equal to the normal operating speed multiplied by a speed multiplying coefficient). During reproduction, when the process flag is detected, the speed at which reproduction occurs is adjusted so as to assure that at least the intra-picture component of the image signal will be accurately reproduced. The reproduced data can then be output in a fixed period in correspondence to the speed multiplying number that determines the current operating speed of the apparatus.

Abstract: An apparatus for decoding edited coded data for video signals where the decoding apparatus is capable of preventing a disturbance of a video image at the editing point. During editing of video signals, an edit header is added before and after the editing point, indicating a valid data portion and an invalid data portion on the video signal. A data start/end detector detects when an invalid data portion occurs on a coded video signal. The decoder decodes the video signal according to the edit header, but inhibits decoding of the invalid data portion such that decoding begins again at the next valid data portion. By inhibiting the decoding of unnecessary data corresponding to the invalid data portions, disturbance of the video image is prevented at the editing point.
