Background
The television has become the first choice of the household audio-visual products due to the characteristics of large screen, high resolution and the like, and is generally applied nowadays. In order to adapt to the resolution of the tv set to obtain the best picture output, the set-top box may support switching of multiple resolutions, such as 2160P, 1080I, 720P, etc. However, when the resolution set by the set-top box is higher than the maximum resolution that the television can support, the television will have no picture output; when the resolution set by the set-top box is lower than the maximum resolution which can be supported by the television, the television picture cannot achieve the best effect, and the resource is seriously wasted. The problem of adapting the resolution of the set-top box to the resolution of the television becomes critical. In the prior art, the adaptation with the resolution of the television can be performed by manually setting the system parameters of the set-top box. The manual setting method requires the user to remember the maximum resolution supported by the tv, and in the case of having multiple tvs or frequently replacing tvs, the manual setting method is cumbersome to operate and is prone to output the resolution not supported by the tvs, which results in a black screen of the tvs.

Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
The embodiment provides a method for self-adaptive output resolution suitable for an intelligent set top box. The method comprises the following steps:
step S1, connecting the set-top box to the television and obtaining the highest resolution supported by the television; in this embodiment, after the set top box is connected to the television through an HDIM connection line, Extended Display Identification Data (EDID) of the television is acquired, and all resolutions supported by the television, including the highest resolution supported by the television, are acquired according to the EDID information of the television.
Step S2, the set-top box is connected to the network and receives the first video signal, and analyzes the resolution of the first video signal; in this embodiment, the set-top box is connected to a network through a network cable, so as to receive a video signal from a network end.
Step S3, the set top box converts the obtained first video signal into a second video signal according to the highest resolution supported by the television and the obtained resolution of the first video signal, and sends the second video signal to the television, where the resolution of the second video signal is not higher than the highest resolution supported by the television.
Specifically, when the highest resolution supported by the set top box is not lower than the highest resolution supported by the television, if the resolution of the first video signal is not higher than the highest resolution supported by the television, the resolution of the second video signal is equal to the resolution of the first video signal. For example, when the maximum resolution supported by the set top box is 2160P @25Hz and the maximum resolution supported by the television is 2160P @25Hz, if the resolution of the played video source is 2160P @50Hz, that is, the resolution of the first video signal is 2160P @50Hz, the resolution of the second video signal is 2160P @25 Hz.
Specifically, when the highest resolution supported by the set top box is not lower than the highest resolution supported by the television, if the resolution of the first video signal is higher than the highest resolution supported by the television, the resolution of the second video signal is lower than the highest resolution supported by the television. For example, when the maximum resolution supported by the set top box is 2160P @50Hz and the maximum resolution supported by the television is 2160P @25Hz, if the resolution of the played video source is 2160P @50Hz, that is, the resolution of the first video signal is 2160P @50Hz, the resolution of the second video signal is 2160P @25 Hz.
Specifically, when the highest resolution supported by the set top box is lower than the highest resolution supported by the television, if the resolution of the first video signal is not lower than the highest resolution supported by the television, the resolution of the second video signal is lower than the resolution of the first video signal. For example, when the maximum resolution supported by the set top box is 2160P @25Hz and the maximum resolution supported by the television is 2160P @50Hz, if the resolution of the first video signal is 2160P @50Hz, the resolution of the second video signal is 2160P @25 Hz.
Further, when the set-top box receives an instruction of manually switching the resolution, which is input by a user, and if the resolution selected by the user is the resolution which is not supported by the television, the set-top box feeds back a corresponding prompt signal and transmits the prompt signal to the television. The prompt signal comprises voice prompt information, text prompt information or image prompt information.
In summary, the method for adaptively outputting the resolution suitable for the intelligent set top box according to the embodiment can realize that the set top box automatically switches the resolution of the output video signal according to the resolution condition supported by the television and the resolution of the video signal by acquiring the resolution supported by the television, so that the television picture effect reaches the best.

For example, when the maximum resolution supported by the set top box is 2160P @50Hz and the maximum resolution supported by the television is 2160P @25Hz, if the resolution of the played video source is 2160P @50Hz, that is, the resolution of the first video signal is 2160P @50Hz, the resolution of the second video signal is 2160P @25 Hz.
In this embodiment, when the highest resolution supported by the set top box is not lower than the highest resolution supported by the television, if the resolution of the first video signal is higher than the highest resolution supported by the television, the resolution of the second video signal is lower than the highest resolution supported by the television. For example, when the maximum resolution supported by the set top box is 2160P @50Hz and the maximum resolution supported by the television is 2160P @25Hz, if the resolution of the played video source is 2160P @50Hz, that is, the resolution of the first video signal is 2160P @50Hz, the resolution of the second video signal is 2160P @25 Hz.
In this embodiment, when the highest resolution supported by the set top box is lower than the highest resolution supported by the television, if the resolution of the first video signal is not lower than the highest resolution supported by the television, the resolution of the second video signal is lower than the resolution of the first video signal. For example, when the maximum resolution supported by the set top box is 2160P @25Hz and the maximum resolution supported by the television is 2160P @50Hz, if the resolution of the first video signal is 2160P @50Hz, the resolution of the second video signal is 2160P @25 Hz.
