DIGITAL VCR WITH NON-STANDARD SPEED PLAYBACK

摘要

As depicted in the figure above, the instant invention provides a "trick play" method for recording MPEG compatible advanced television (ATV) signals. The system comprises an ATV decoder (100), a "trick play" processor (200) and an SD DVCR (300). "Trick play" processor (200) compresses image signals from decoder (130) to form a "trick play" data stream (251). The "trick play" data stream is multiplexed, in sector constructor (340), with the received data stream, from block structurer (330) to form a record signal. Multiplexer (340) ensures that "trick play" data stream (251) is recorded at specific track locations by recording system (350), these specific track locations facilitate "trick play" reproduction at a plurality of speeds in both forward and reverse directions. The video processor (150) provides a selection function for switching between ATV and "trick play" video images.
