摘要： An apparatus for reproducing digital information from a recording medium having a plurality of parallel tracks and digital information recorded thereon as n-channel (n being an integer greater than or equal to 2) digital signals. The n-channel digital signals are reproduced by n-reproducing heads. The digital information contained in the reproduced signals is stored in a storage device. Discriminating data is obtained for determining which of the n-channel digital signals reproduced correspond to the reproducing heads. The timing of an access device, accessing the storage device for performing a predetermined processing of the digital signals stored in the storage device relative to the reproducing timing of the digital information reproduced by the n reproducing heads, is controlled in accordance with the discrimination data.

摘要： An information recording apparatus records data, which is in the format of packets received by broadcast, on a recording medium having a write/read capability. If the received data contains any unnecessary items of data that can be reproduced later, these items of data are eliminated at the time of recording on the recording medium. At playback, the eliminated items of data are restored and appended to the data read in from the recording medium. The resulting data, which is substantially the same as that in the packets received by broadcast, is outputted to a playback apparatus capable of reproducing the broadcast.
