Digital television receiver compatible with multiple data connecting interfaces

Abstract

The invention relates to a digital television receiver compatible with multiple data connecting interfaces. The digital television receiver compatible with multiple data connecting interfaces comprises a first demodulation processing module, a second demodulation processing module, a digital image filtration module, a digital program channel switch module, a user input module, a controller module, a display module and a unified data interface module, wherein digital image filtering is carried out on digital program data output by the first demodulation processing module by the digital image filtration module, the digital program channel switch module is connected with the display module and the unified data interface module, the controller module is connected with the digital program channel switch module and the user input module, and then digital program data output by the digital image filtration module or the second demodulation processing module are switched to the display module or the unified data interface module according to the selection of a user. According to the digital television receiver compatible with multiple data connecting interfaces, digital programs treated with filtering processing or not treated with filtering processing can be selected for a display or external equipment flexibly according to requirements of the user.

Description

technical field [0001] The invention relates to the field of television reception, in particular to a digital television receiver compatible with multiple data connection interfaces. Background technique [0002] Television is an important entertainment and monitoring tool for people. With the rapid development of TV technology, the TV types are transitioning from analog TV of black and white TV and color TV to digital TV. Digital TV has the unparalleled advantages of analog TV. It can transmit more program content in a limited frequency band, and the clarity of the program content it transmits is also greatly improved. Therefore, although at the present stage, analog TV still has certain market, but various types of digital TV is the direction of future development and research. [0003] However, the existing digital TV receivers often can only receive and play one digital TV program, but cannot play TV signals on the display and play TV signals on the external equipment ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing digital TV receivers often can only receive and play one digital TV program, but cannot play TV signals on the display and play TV signals on the external equipment when using an external interface to connect to external equipment. At the same time, the external interface is relatively simple, and can only send and receive signals in one of the formats of DVI, HDMI or DisplayPort, which cannot meet the needs of users with various peripherals to play digital TV programs.
