Patent ID: 7254316

Claim:
A data recording, editing and reproducing method for recording, editing and reproducing video and/or audio data (DV data) in the DV format, said method comprising the steps of: receiving DV data through an IEEE 1394 Interface; temporarily storing the received DV data into a DV data storage region of a buffer memory; separating and reading out audio data and/or video data from the DV data stored in the DV storage region of the buffer memory and writing the read out audio data and/or video data into audio and/or video data storage regions of the buffer memory; recording the DV data stored in the DV storage region of the buffer memory into a DV storage region of a disc means; recording the audio and/or video data stored in the audio and/or video data storage regions of the buffer memory into audio and/or video storage regions of the disc means; transmitting post recording audio and/or video data into the post recording data storage region on the buffer memory; recording the post-recording audio or video data stored in the post-recording audio or video data region of the buffer memory into post-recording audio or video data regions of the disc means; editing the audio and/or video data stored in the audio and/or video data storage regions of the disc means by replacing the audio data and/or video data by the post-recording audio and/or video data stored in the disc means, and reproducing the edited audio and/or video data on the disc means by storing the edited audio data and/or video data and the DV data on the disc means into the respective data storage regions of the buffer memory, multiplexing the stored audio and/or video data with the stored DV data and sending out multiplexed audio and/or video data and DV data as DV data.
