    Abstract: Apparatus for decoding a transmitted digital signal includes a receiver, such as a recorded tape (31) and a playback head (32), for receiving the transmitted digital signal, a filter (34) for limiting the frequency of the output of the receiver to below a predetermined cut-off frequency which may be the Nyquist frequency of the digital signal, a generator (36, 37) for generating a clock signal with a frequency (fs) equal to the transmitted rate of the digital signal from the output of the receiver, and a converter (35) for sampling the output of the filter (34) by the clock signal and for converting the same into a binary signal. A processing circuit (39a to 42) is arranged to process the output of the converter (35) to decode the transmitted digital signal according to a predetermined method, such as a class IV partial response method, in which case the processing circuit may include a transversal filter (39a to 41).

    Abstract: A TELEVISION RECEIVER APPARATUS (3) HAS LARGE VERSATILITY TO ADAPT ITSELF TO NEWLY OFFERED SERVICES OR NEW MODES OF USE. AN EXTERNAL MEMORY ELEMENT (100) LOADED WITH A FLASH MEMORY (34) IS CONNECTED TO THE RECEIVER APPARATUS THROUGH AN EXTERNAL MEMORY INTERFACE (45) HAVING A CONNECTOR AND AN INTERFACE CIRCUIT. THE EXTERNAL MEMORY ELEMENT (100) STORES INFORMATION SUCH AS A PROGRAM FOR IMPLEMENTING AN ADDITIONAL FUNCTION OR DATA SUCH AS VIDEO AND AUDIO DATA. THE INFORMATION STORED IN THE EXTERNAL MEMORY ELEMENT IS TAKEN UP BY THE RECEIVER APPARATUS (3) THROUGH THE EXTERNAL MEMORY INTERFACE (45). THE INFORMATION FROM THE EXTERNAL MEMORY ELEMENT (100) IS PROCESSED BY A CONTROLLING PORTION (30) OF THE RECEIVER APPARATUS (3) SO AS TO BE SUBJECTED TO USE.

    Abstract: A method of dubbing compressed digital video signals (32) adopted for an apparatus (1-15) for efficient coding and subsequent recording/playback of video signals. In the method of dubbing compressed digital video signals, on a playback unit side (8-15), after padding error data by an error processing circuit with respect to an error uncorrectable in error correction by an ECC circuit (10) of playback, the digital video signal is provided with a parity for transmission by a parity generating circuit (6) and is then transmitted to a recording unit side (1-7). On the other hand, on the recording unit side (1-7), after padding error data by an error processing circuit with respect to an error uncorrectable in error correction by an ECC circuit (10) of transmission, the digital video signal is provided with a parity for recording by a parity generator (6) and is then recorded in a recording medium.
