Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] The technical idea of ​​the digital TV set-top box of the embodiment of the present invention is as follows:

[0023] a) HD / SD set-top box public module and proprietary module division

[0024] Division principle: the interoperable module must meet the requirements of HD module and SD module at the same time, and the redundancy of the interoperable module circuit should be as small as possible to reduce the cost increase caused by redundancy.

Abstract

The invention provides a digital TV set-top box and a manufacturing method of the digital TV set-top box. The digital TV set-top box includes a base plate, a connection mechanism and a module card, wherein: the base plate has a channel module, a peripheral module, an audio and video output processing module and a connection Mechanism female socket, used for TV RF signal reception, analog audio and video output and data serial input / output channel; module card, which is a high-definition module card or standard definition The HD module card or SD module card is connected to the backplane by plugging and unplugging, and the decoding and analog output of digital TV HD programs or SD programs are performed to realize the application service based on the digital TV network; among them, the female socket of the connecting mechanism and the male socket of the connecting mechanism The header is used to realize the physical connection and signal transmission between the functional modules of the backplane and the module card. The invention realizes the upgrade of the function of the digital TV set-top box with a modular structure, reduces the upgrade cost and reduces hardware waste.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a digital television set-top box and a manufacturing method of the digital television set-top box. Background technique [0002] Set-top box hardware usually consists of four parts: channel module, decoding SOC (System on chip, system-on-chip, also known as system on chip) and its supporting circuit module, peripheral module, audio and video output processing module; [0003] The channel module includes: tuner, demodulation chip and peripheral devices.
