EQUIPMENT AND METHOD FOR RECORDING AND REPRODUCING IMAGE AND SOUND

摘要

PURPOSE: The equipment and method is provided to be memorized to an another recording equipment independently of each video and sound signals. CONSTITUTION: An AV server comprises of; a processor section(30) for conducting various signal proceedings including the compression and expression; a video RAID section(21) for storing video signals; a audio RAID section(10) for storing sound signals. The processor section(30) has a plurality of I/O boards(32n) and manage channels as many as I/O boards. Signals(Avin) including the video and sound signals is input to each I/O boards and is output from each I/O boards. Individual I/O boards supply a sound signal and a video signal to the audio RAID section(10) and the video RAID section(21), respectively, have a audio RAID interface section(33) and a video RAID interface section(34) which receive individually a sound and video signal to the audio(10) and video RAID section(21). The video RAID section(21) reproduce the writing and reading of video sound signals in use of a hard disk, has the RAID-3 structure. The audio RAID section(10) reproduce the writing and reading of sound signals in correspondence with each of a plurality of sound signal channels independently of the video RAID section(21) in use of a hard disk memorizing sound signals.
