ABSTRACT:
A MUSE encoder converts a HDTV signal into a MUSE signal and supplies the converted MUSE signal to a digital recording circuit 52 of a digital VTR. The supplied MUSE signal includes audio data and additional information, each being a ternary signal. A state of a ternary signal at one sampling point is discriminated by a ternary discrimination circuit 102, with the result thereof being indicated as a two-bit digital signal by a two-bit indicating circuit 103. Accordingly, the number of bits required for the audio data at one sampling point can be compressed from eight bits to two bits. In addition, by converting two successive discriminated results by the ternary discrimination circuit 102 into a binary signal by means of a ternary/binary converting circuit 104, the number of bits required at two sampling points can be reduced from 16 bits to three bits. As a result, a recording bit rate for the MUSE signal, to be digitally recorded on the magnetic tape, can be reduced.
