Abstract

The invention relates to a power-save method controller of digit image player and relative method, wherein for example, when DVD player and digit portable camera are connected via IEEE 1394 interface, the A / V data of digit portable camera is received by DVD player and stored into disc; DVD player sends opcode of AVC (voltage optimize control) command added with power-save-disable command, to forbid the camera into power-save mode, when camera transmits A / V data into DVD player. Therefore, the invention can avoid A / V data storage being stopped illegally.

Description

technical field [0001] The present invention relates to a power-saving mode control device of a digital image playback device and a method thereof. Especially refers to: the digital camcorder outputs A / V data, which is received by the DVD player and stored in the optical disc, which can prevent the digital camcorder from entering the power saving mode (Power Save Mode) The power saving mode control of digital video playback equipment Apparatus and method thereof. Background technique [0002] Now, various digital image playback apparatuses capable of playing back high-quality video data and high-quality audio data, such as DVD-Recorders and DV-Camcorders, have been widely used. The above DVD player can process and compress the A / V data stream according to the MPEG method, and store it into a rewritable DVD (DVD-RW, DVD+RW, DVD-RAM) or a single-shot DVD (DVD-R, DVD +R) etc. [0003] In addition, the above-mentioned digital camcorder can perform signal processing on the rec...
