Video and audio data demultiplexer having controlled synchronizing signal

摘要: When the decoding of video data is repeatedly started and interrupted, a demultiplexer prevents synchronizing signal from being discontinued hence displayed image disturbed immediately after decoded. demultiplexing start time SCR DTSV are read multiplexed bit stream, an initial STC value: -- calculated according to equation: initial.sub.-- STC=SCR-(Pp-((DTSV-SCR)+VIDEO.sub.-- DECODE.sub.-- DELAY)% Pp) where VIDEO DECODE DELAY represents time, which known, display image, Pp frame period vertical signal, % operator indicative remainder produced by division previous value subsequent value. The whose measured in synchronism with signal. equalized SCR, started. DTSV,
