发明名称 Recording and reproducing digital video data.
摘要 <p>A digital video tape recorder (3), which operates to receive an advanced television (ATV) signal to be recorded, provides a portion such as a low-band coefficient of an intra-coded frame of the ATV signal as variable-speed data, and records the digital video data and the variable-speed data in a main area (A1) and a marginal area (A2), respectively, of successive tracks on a record medium in which the marginal area is located on each track at a position which is reproducible in a fast-speed reproducing mode. The digital video tape recorder reproduces the recorded data in the fast-speed reproducing mode by reproducing the portion of the signal stored from the marginal area of each track which is located at specific reproducible areas. &lt;IMAGE&gt;</p>
