Satellite digital simulation color television receiving system

Abstract

The invention provides a satellite digital simulation color television receiving system comprising an infrared receiving module, a digital signal processing unit, a simulation signal processing unit, an image and sound signal processor and a microcontroller. The microcontroller carries out the identification processing for remote control infrared signals received by the infrared receiving module and controls the digital signal processing unit or the simulation signal processing unit according to the identification processing results. The invention carries out the identification processing for key control signals or the remote control infrared signals received by the infrared receiving module and controls the digital signal processing unit or the simulation signal processing unit according to the identification processing result through the microcontroller so as to achieve the purposes of outputting the images and sound; the invention can realize the control of the digital signal processing unit or the simulation signal processing unit only through the microcontroller, and can achieve the corresponding effect by only requiring a remote controller correspondingly, thereby reducing the cost and facilitating the use of the users.

Description

Technical field: [0001] The invention relates to a satellite digital analog color television receiving system. Background technique: [0002] At present, TV signals have not been completely converted into digital signals. The TV signals sent by some TV stations are analog signals, while other TV stations are sending digital signals. Therefore, for users who have already purchased analog TV sets, they can only purchase an additional set-top box in order to watch digital TV, which will undoubtedly increase the user's use cost. [0003] For the convenience of users, TV manufacturers have begun to produce TVs that can receive digital and analog signals, but this kind of TV simply combines the software and hardware of the set-top box with the software and hardware of the TV, and generally uses the TV as the main On the control end, the software and hardware of the set-top box are used as an input channel of the TV. Although this realizes the reception of digital and analog signals on ...

AI Technical Summary

Problems solved by technology

Although this realizes receiving digital signals and analog signals on a TV, it only puts the set-top box into the TV from the outside of the TV, not a complete all-in-one machine, and this TV needs to be equipped with two remote controls , one controls the set-top box, and the other controls the TV, which is very inconvenient for users to use

[0004] The disadvantage of the prior art is that two remote controllers need to be operated when using the existing TV set capable of receiving digital signals and analog signals, and the operation is more complicated, which brings inconvenience to the user, and in the process of use , there will also be a phenomenon that the set-top box screen menu display overlaps with the TV screen menu display, which affects the user's use
