Abstract

The invention relates to the field of digital televisions. The invention solves the problem that the prior integrated digital televisions do not have expansibility, and provides a integrated digital television and an expansion method thereof. The invention has the technical proposal that the integrated digital television comprises a main unit , a digital television module and an extension module,wherein the digital television module comprises a main interface, an expansion interface and a multi-path signal processing module; the digital television module is connected with the television mainunit by the main interface; the multi-path signal processing module is connected with the expansion interface and the main interface; and the expansion module is connected with the digital televisionmodule by the expansion interface on the digital television module. The integrated digital television is convenient for users, and the expansion method is suitable for integrated digital televisions.

Description

technical field [0001] The invention relates to digital television technology, in particular to the technology of a modular digital television integrated machine. Background technique [0002] Most of the existing digital TV all-in-ones adopt the method of digital TV modules, that is, the all-in-one digital TV is composed of two parts: a TV host and a digital TV module, and a unified interface is used to transmit information such as control, power supply and signals between the two parts. 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. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a digital TV integrated machine and its expansion method in order to ...
