Bandwidth can be reduced by MUSE (Multiple Sub –Nyquist Sampling Encoding) system MUSE stands for Multiple Sub-Nyquist sampling encoding and is an HDTV bandwidth compression schemedeveloped by NHK. It uses the fundamental concepts of performance exchange in the spatio-temporal ( transitory transformation) domain along with motion compensation to reduce the transmission bandwidthdown to near 10MHz. The processed HDTV signal can then be transmitted using a single DBS channel. In MUSE the luminance andcolour information are sent by Time-multiplexed components (TMC). In Muse the luminance and colour information are sent by timemultiplexedcomponents. The colour information is sent sequentially with a time compression offour.
MUSE stand for MUltiple Sub-Nyquist Sampling Encoding and NHK (Nippo Hoso Kyokol) is Japanese company develop encoding system for HDTV. In this system the luminance and colour information are sent by Time Multiplxed component Colour information is sent sequentially with time compression of four. So bandwidth is reduced. Muse system has 1125 interlaced scanning line. It has 60 Hz frequency with 5/3 aspect ratio. The pre compression for Y signal is 20 MHz and chrominance signal is 7Mhz. MUSE digital Audio system is called DANCE (Digital Audio Near-Instantaneous Compression and expansion).
