Patent ID: 7206502

Claim:
An apparatus for recording and reproducing digital data, comprising: receiving means for receiving first compressed data composed of a plurality of packets, said first compressed data including a plurality of programs multiplexed in a time division manner; data separating means for extracting specific compressed audio/video data corresponding to a desired program from the first compressed data received by the receiving means; record control means for generating second compressed data including the compressed audio/video data extracted by the data separating means; recording means for recording the second compressed data generated by the record control means in a same order in which the first compressed data is received by the receiving means; data reproducing means for decoding the compressed audio/video data included in the second compressed data simultaneous with additional second compressed data being recorded in the recording means; reproduction control means for reading the second compressed data from the recording means and transmitting the second compressed data to the data reproducing means in a same order in which the second compressed data is recorded in the recording means; time division control means for controlling the transmitting and reading of the second compressed data to and from the recording means in a time division manner and for controlling the record control means and the reproduction control means in a time division manner; switching means for switching between transmitting the compressed audio/video data extracted by the data separating means to the data reproducing means and transmitting the second compressed data from the reproduction control means to the data reproducing means, said switching means being disposed between the data separating means and the data reproducing means, said switching means being disposed between the reproduction control means and the data reproducing means, wherein the time division control means is disposed between the record control means and the recording means with respect to the second compressed data being transmitted to the recording means such that the time division control means is directly connected to both the record control means and the recording means, wherein the time division control means is disposed between the recording means and the reproduction control means with respect to the second compressed data being transmitted from the recording means such that the time division control means is directly connected to both the recording means and the reproduction control means, wherein an output of the data separating means is directly connected to an input of the switching means, and wherein an output of the switching means is directly connected to an input of the data reproducing means.
