Abstract: An arrangement for enhancing an image corresponding to a television signal including a digital component includes a variable bandwidth filter and a control unit for controlling the bandwidth of the filter in response to the bit error rate (BER) of the digital component of the television signal.

In one embodiment, the control unit is responsive to both the BER and the "darkness" of the image represented by the television signal so as to restrict the bandwidth more for relatively dark areas than for relatively light areas.

Abstract: When transmitting an audio signal by multiplexing in a synchronous period of a video signal, a buffer memory for time axis adjustment of the audio signal is controlled. The number of audio signal samples in the buffer memory is detected in every n fields (n being a positive integer) of video signal, and when it is different from a specific value, the read or write address of the buffer memory is preset, so that the number of audio signal samples in the buffer memory is kept constant at the moment of inspection in every n fields. Besides, by inspecting the number of audio signal samples in the buffer memory in one field or more, a line providing a maximum or minimum value of the number of samples is stored, and thereafter the number of audio signal samples in the buffer memory in that line is kept constant, so that the buffer memory capacity may be utilized effectively.
