Embodiment Construction

[0016] Please refer to FIG. 2 , which is a schematic block diagram of the playback device 10 of the present invention. The playback device 10 includes a receiving module 12 installed on the housing for receiving externally input image signals and audio signals. A storage module 14 can be a read-only storage device, such as a DVD optical drive or a VCD optical drive, or a flash storage device, such as a memory in formats such as CF, SD or MMC, or a hard disk drive device, such as a hard disk Devices such as computer or Micro driver, which are used to store the data to be played. An input module 16 is used for inputting the control parameters of the playback acceleration of the data stored in the storage module 14 .

[0017] The input module 16 includes an acceleration switch 18. When the acceleration switch 18 is activated, the playback device 10 will play audio and video at the acceleration corresponding to the state acceleration of the acceleration switch 18. When the accele...

Abstract

The present invention relates to a data playback method for playback device. It is mainly characterized by that the data of storage medium mounted in said playback device can be played back at an acceleration.

Description

technical field [0001] The invention relates to a method for playing data on a playing device, in particular to a method for playing data at an acceleration on a playing device. Background technique [0002] With the vigorous development of audio-visual multimedia technology, various audio-visual playback devices are gradually popularized in every family, such as traditional video recorders to the popular digital video recorders (digital video recorders) and so on. Although the technologies of various audio-visual playback devices have become more and more mature, such as the improvement of audio-visual quality, the improvement of storage media, etc., the flow control of their audio-visual playback has not changed much. [0003] Generally speaking, the audio-visual playback process control is composed of three basic control elements: play / pause, playback speed control, and playback direction change. In terms of playback speed control, the known playback speed control is con...
