Embodiment 1

[0022] This embodiment provides a method for adaptive output resolution suitable for a smart set-top box. The method comprises the steps of:

[0023] Step S1, the set-top box is connected to the TV and obtains the highest resolution supported by the TV; in this embodiment, after the set-top box is connected to the TV through an HDIM cable, the Extended Display Identification Data (Extended Display Identification Data) of the TV is obtained , EDID), obtaining all resolutions supported by the TV according to the EDID information of the TV, including of course the highest resolution supported by the TV.

[0024] Step S2, the set-top box is connected to the network and receives the first received video signal, and analyzes the resolution of the first video signal; in this embodiment, the set-top box is connected to the network through a network cable to receive the video signal from the network.

[0025] Step S3, the set-top box converts the obtained first video signal into a sec...

Embodiment 2

[0032]This embodiment provides a system for adaptive output resolution suitable for smart set-top boxes. The system includes a reading analysis module, a signal transceiving module, a resolution switching module, a manual setting module and a prompt module. The reading analysis module is used to connect to the TV and obtain the highest resolution supported by the TV; the signal transceiver module is used to connect to the network and receive the first received video signal, and analyze the first video signal resolution; the resolution switching module is respectively connected to the reading analysis module and the signal transceiving module, and is used to obtain the resolution of the first video signal according to the highest resolution supported by the TV and the obtained first video signal converting the first video signal into a second video signal, and sending the second video signal to the TV, the resolution of the second video signal is not higher than the highest reso...

Abstract

The invention discloses a method and system applicable to a set top box and capable of adaptively outputting resolution. The method comprises the following steps of S1, connecting the set top box to atelevision and obtaining the highest resolution supported by the television; S2, connecting the set top box to a network, receiving a first receiving video signal, and analyzing the resolution of thefirst video signal; S3, using the set top box to convert 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 sending the second video signal to the television, wherein the resolution of the second video signal is not higher than the highest resolution supported by thetelevision. Therefore, the set top box automatically switches and outputs the resolution of the video signal according to the condition of the resolution supported by the television and the resolutionof the video signal by acquiring the resolution supported by the television, so that the best picture effect of the television is achieved.

Description

technical field [0001] The present invention relates to the technical field of digital television terminals, in particular to set-top boxes, and more specifically, to a method and system for adaptive output resolution applicable to set-top boxes. Background technique [0002] Television sets have become the first choice for family audio-visual products because of their large screen and high resolution, and are now widely used. In order to adapt to the resolution of the TV to obtain the best picture output, usually the set-top box can support switching of multiple resolutions, such as 2160P, 1080P, 1080I, 720P and so on. However, when the resolution set by the set-top box is higher than the maximum resolution the TV can support, the TV will have no picture output; when the resolution set by the set-top box is lower than the maximum resolution the TV can support, the TV picture will not be able to To achieve the best results, resulting in a serious waste of resources. Theref...
