Problems solved by technology

However, it is impossible for all current analog TVs to be turned off in a short period of time. Moreover, most of the existing TVs are analog TVs or digital TVs with a single signal source, or they can be played by adding a set-top box on the analog TV. The function of digital TV channels tends to take up too much space, and in terms of operation, users must switch between different machines, which is extremely inconvenient

Embodiment Construction

[0015] The implementation of the present application will be described in detail below with reference to the accompanying drawings and examples, so as to fully understand and implement the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects.

[0016] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the...

Abstract

The invention discloses a television signal receiving module and method. The module comprises a digital-analog-integrated tuner, a system chip SOC and an audio-video switching chip. The method includes: radio frequency signals are converted into intermediate digital signals or analog signals through the digital-analog-integrated tuner; the intermediate digital signals are demodulated and decoded into analog video signals and analog audio signals through the system chip SOC; the analog signals or the processed analog video signals and audio signals are switched and allocated with programs through the audio-video switching chip. Accordingly, the television signal receiving module has both a digital signal receiving and processing function and traditional analog signal receiving and processing function.

Description

technical field [0001] The present application relates to the field of televisions, in particular to a television signal receiving module and a receiving method. Background technique [0002] With the development of communication technology, traditional analog TV is gradually unable to meet people's demand for increasingly rich TV programs. Compared with traditional analog TV, digital TV has a higher level of image and sound quality, and can receive more TV programs and other digital information, therefore, digital TV has been gradually integrated into people's daily life. [0003] The current global digital TV broadcasting system is roughly divided into several standards, such as Digital Video Broadcasting (DVB), Advanced Television Standards Committee (ATSC), Integrated Services Digital Broadcasting (ISDB) and Digital Television Terrestrial Broadcasting (DTMB). However, it is impossible for all current analog TVs to be turned off in a short period of time. Moreover, most ...
