Abstract

The present invention relates to a power-saving mode control device and method for digital image playback equipment. For example, a DVD player and a digital camcorder are connected together through an IEEE 1394 interface. In this state, the A / V data output by the digital camcorder is The DVD video player receives and stores it in the disc, and the DVD player adds an instruction equivalent to prohibiting entering the power saving mode (Powersave_Disable) in the instruction operation code (Opcode) of the AVC (Voltage Optimizing Control) command sent by the DVD video player to the digital camcorder. When the digital camcorder is transmitting A / V data to the DVD player, it enters the power saving mode. Therefore, it is possible to effectively prevent the process of storing A / V data from being abnormally terminated.

Description

technical field [0001] The invention relates to a power-saving mode control device and method for digital image playback equipment. In particular, it refers to the power saving mode control of the digital image playback device that can prevent the digital camcorder from entering the power saving mode (Power Save Mode) during the process of outputting A / V data from the digital camcorder, receiving it from the DVD player, and storing it into the disc. Apparatus and method thereof. Background technique [0002] Now, various digital image playback devices capable of playing high-definition video data and high-quality audio data, for example, DVD video disc players (DVD-Recorder) and digital camcorders (DV-Camcorder) etc. have been generally used. The above-mentioned DVD player can process and compress the A / V data stream according to the MPEG method, and store it in rewritable DVD (DVD-RW, DVD+RW, DVD-RAM) or single-burn DVD (DVD-R, DVD +R) etc. [0003] In addition, the abov...
