High capacity surveillance system with fast search capability

摘要: A surveillance system having a plurality of MPEG compressed data streams each originating from separate video/audio source. The is stored on hard disk and streamed to tape in real time with set markers readable independent the video signal. partitioned tape, partition including blocks, block synchronized frames stream, stream map, telemetry information, roster information positioning data. Each includes duplicate map directory, within information. Set marks fast forward or rewind mode, are placed every second position just before file mark duplication directory. cassette an EEPROM, which holds directory redundant useful for searching. In case error, automatically restores itself when inserted into deck.
