Recording and playback apparatus and method, program storage medium, and program

Abstract

A recording and playback apparatus and method, a program storage medium and a program by which AV signals of a program being recorded can be converted into AV signals of another format are disclosed. First, it is discriminated whether or not a recording process is started. If it is discriminated that a recording process is started, then coded data being currently recorded are read out and converted into coded data of another format. Thereafter, the coded data obtained by the format conversion are recorded onto a hard disk.

1 . A program for causing a computer, which encodes inputted AV signals to produce coded data and records the coded data onto a randomly accessible recording medium and further plays back and decodes the coded data recorded on the recording medium, to execute:
 a production step of encoding the inputted AV signals using a first coding system to produce first coded data;   a first recording step of recording the first coded data produced by the process of the production step onto the recording medium;   a supervision step of supervising the process of the first recording step;   a readout step of reading out the first coded data recorded on the recording medium by the process of the first recording step from the recording medium;   a conversion step of converting the first coded data read out from the recording means by the process of the readout step into second coded data corresponding to a second coding system; and   a second recording step of recording the second coded data converted by the process of the conversion step onto the recording medium;   the processes of the readout step, the conversion step and the second recording step, respectively, being executed simultaneously with the process of the first recording step based on a result of the supervision by the process of the supervision step.
