A recording apparatus of the present invention comprises a compressed data processing unit for performing compression processing of second definition data to generate compressed data, a system data generating unit for generating system data including at least time code, an extended track number generating unit for generating extended track number on the basis of inputted second definition data, a memory unit for storing compressed data and system data, a read-out unit for reading out compressed data and system data which are stored in the memory unit, a control unit for controlling the read-out unit so as to read out, at a predetermined timing, the compressed data and the system data which are stored in the memory unit on the basis of the extended track number, and a recording unit for recording, into second sector, compressed data which has been read out from the read-out unit, and for recording, into third sector, along with extended track number, system data which has been read out by the read-out unit.

Recording apparatus and method

There are provided the delay coarse adjustment circuit , the delay fine adjustment circuit , and the inverter circuit . The delay coarse adjustment circuit stepwise varies a delay amount based on the delay coarse adjustment signal S and supplies the input oscillation signal S with a coarse delay. The delay fine adjustment circuit stepwise varies a delay amount based on the delay fine adjustment signal S and supplies the input oscillation signal S with a fine delay which is smaller than a delay amount supplied by the delay coarse adjustment circuit . The inverter circuit inputs the oscillation signal S from the delay coarse adjustment circuit or the delay fine adjustment circuit . The delay coarse adjustment circuit coarsely adjusts delays. The delay fine adjustment circuit fine adjusts delays. The coarse and fine adjustments provide a precision delay to generate the oscillation output signal S . The delay coarse adjustment circuit , the delay fine adjustment circuit , and the inverter circuit are connected in a ring for stepwise controlling an oscillation signal's oscillation frequency.

Oscillator and oscillator adjustment method with stepwise delay

A picture reproducing device in which a still picture can be recorded/reproduced to high picture quality without requiring a dedicated still picture processor or a RAM configured for storing picture data for processing by the dedicated still picture processor. Input video signals are all processed with DCT in a DCT/IDCT processor 4 as a continuous frame picture from one transform block to another and quantized by the quantizer/dequantizer 5 so as to be then recorded on a recording medium. Reproduced signals from the recording medium are dequantized by the quantizer/dequantizer 5 to give coefficient data which are processed with inverse DCT by the DCT/IDCT processor 4 to generate playback video signals. Responsive to the coefficient data based results of motion detection effectuated from one transform block to another, the playback video signals are outputted as playback video signals from the blocking shuffling/deblocking deshuffling processor 2. At this time, still picture blocks are outputted as a frame, while moving picture blocks are outputted as twice-outputted single-fields.

Recording/reproducing of video signals, with video signals played back as a frame or a twice-outputted single-field depending on whether the recorded signals are directed as still or moving pictures
