Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] In the present invention, an expansion interface is added to the main module of the digital module, and then the expansion module is connected to the expansion interface to realize the power supply of the main module to the expansion module, and the main module is equipped with a multi-channel signal processing module according to the host requirements of the all-in-one TV. Integrate the multi-channel signals of the main module and the expansion module, and finally realize multi-module control.

[0020] Such as figure 1 As shown, the digital module extension method of the all-in-one TV in the present invention is realized by the following steps: a. an expansion interface is added on the main module of the digital module, and an expansion module is connected through the expansion interface, and on the main module Add a multi-channel signal processing module, and...

Abstract

The invention relates to the technical field of digital televisions, in particular to the method for expanding digital modules of integral televisions, which solves the problems of integral televisions in the prior art that the digital modules can not be expanded, and the operation is inflexible. The main points of the technical solution of the method can comprise that an expanding interface is added on a main module of a digital module, the main module is connected with an expanding module through the expanding interface, a plurality of signal processing modules are added on the digital module, when a mode I is selected, only the main module receives and decodes signals, the expanding module stands by, when the mode II is selected, the expanding module receives and decodes the signals, when the mode III is selected, the main module and the expanding module simultaneously receive and decode the signals, and process the decoded signals according to the specific display mode through a plurality of the signal processing modules. The invention has the beneficial effects that the expansibility of the digital module is increased, the multiple-module control can be realized, the operation is flexible, and the method is suitable for integral televisions.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a digital module extension method of an all-in-one television. Background technique [0002] The digital TV all-in-one (referred to as all-in-one TV) mostly adopts the method of digital TV module, that is, the digital TV all-in-one is composed of two parts: the TV host and the digital module, and a unified interface is used for control, power supply and signal between the two parts. Information transfer. At present, the digital TV module has only one interface to connect with the TV host. If you want to replace the module, you need to remove the current module and connect a new one, and it does not support the simultaneous work of two or more modules. It does not have scalability and is not flexible in operation. If a cascading interface is added to the digital TV module, and a corresponding control module is added to the TV host and the module, the expandability of t...
