Method and apparatus for storing MPEG-2 transport streams using a conventional digital video recorder

Abstract

A method and apparatus for storing an MPEG-2 transport data stream with a conventional digital video (DV) recorder is described. The packetized MPEG-2 transport stream data is inserted into a data block of a digital video (DV) frame. The digital video frame is stored on the storage medium of the DV recorder. The DV frame may be inserted into an isochronous data transfer packet for transfer to the recorder over an IEEE 1394 serial bus. On the other hand, the MPEG transport stream data may be transferred to the recorder over the IEEE 1394 serial bus before the data is inserted into the DV frame for storage. For playback, the stored DV frame can be copied into an IEEE 1394 packet for transfer to the television receiver where the MPEG data is extracted from the frame, decoded and presented. On the other hand, the MPEG data may be extracted from the stored DV frame before transfer to the receiver over the IEEE 1394 bus.
