Embodiment Construction

[0041] The implementation of the present invention is described below with specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments.

[0042] see figure 1 , figure 1 It is a schematic diagram of the system architecture of an embodiment of the audio and video drive system of the present invention. As shown in the figure, the audio and video driving system 1 of the present invention includes a video driving module 10 , an audio driving module 11 and a low output linear voltage regulator module 12 . The video driver module 10 is used to receive a video input signal S1, and is used to output a video output signal S2 to an output load (not shown); the audio driver module 11 is used to receive an audio input signal S3, and is used to output an audio output signal S...

Abstract

The invention discloses an audio and video drive system, and the system comprises a video drive module and an audio drive module, which are used for receiving input signals and outputting output signals. The system also comprises a low-output-linearity voltage stabilizer module which is used for converting external power and supplying a default voltage to the video drive module and the audio drive module. The video drive module is also used for detecting whether the input signal is received or not and whether an output load is connected or not: starting the video drive module and the audio drive module if the input signal is received and the output load is connected, or else enabling the video drive module and the audio drive module to be in a standby state.

Description

technical field [0001] The invention relates to an audio and video driving system, especially an audio and video driving system having both a video driving module and an audio driving module. Background technique [0002] Generally speaking, in the existing audio and video driver solutions, the audio driver chip and the video driver chip are designed as separate chips and packaged separately, wherein the audio driver chip and the video driver chip are respectively controlled by the main chip, and the There is no logical relationship between them. However, such a solution not only increases the area of ​​the PCB circuit board and the cost of repeated packaging, but also ignores the inevitable logical relationship between the audio driver and video driver chips. [0003] Therefore, how to provide an audio and video driver system that integrates the audio driver and the video driver so as to reduce the area of ​​the PCB circuit board and reduce the cost of repeated packaging i...
