A multichannel recording and reproducing apparatus

摘要

A multichannel recording and reproducing apparatus is disclosed which includes: an input and output circuit (103); a buffer (104) for temporally storing multichannel of video data through inputting and outputting circuit; a disc unit (106) for storing the video data; a disc interface (105); a user interface circuit (110) for receiving recording and reproducing commands and a corresponding file name from a user; a control circuit (109) responsive to the user interface (110) for obtaining one of N video channel circuits of the input and output circuit (103) for inputting and outputting video data and receiving recording and reproducing commands; a filing circuit (107) controlling files and determining first and second address data of the disc unit (106) according to the recording and reproducing commands respectively; an access control circuit (108) for accumulating the recording and reproducing commands and supplying each of the accumulated recording and reproducing commands when the disc interface (105) is in a non-operating condition with priority provided to either of the recording or reproducing command according to priority data. The inputting and outputting circuit (103) may include a digital satellite broadcasted video data receiver and a separater for separating the multiplexed digital satellite broadcasted video data into a plurality of sets of digital video data. <IMAGE>
