DETAILED DESCRIPTION

[0022] In order to make the objects, technical solutions, and advantages of the embodiments of the present application more apparent, the technical solutions according to the embodiments of the present application will be described below clearly and fully with reference to the drawings in the embodiments of the present application, and apparently the embodiments described below are only a part but not all of the embodiments of the present application. Based upon the embodiments here of the present application, all the other embodiments which can occur to those skilled in the art without any inventive effort shall fall into the scope of the present application.

[0023] As illustrated in FIG. 1, a method for setting transparency of a screen menu according to an embodiment of the present application includes the following steps:

[0024] In the step S101, screen menu data is received.

[0025] In the step S102, the transparency of an area to be adjusted in the received screen menu data is set as a preset transparency, and the received external video signal is superimposed onto the screen menu data in which the transparency has been set, and the superimposed data is transmitted to a display screen for displaying.

[0026] Herein, the preset transparency is a transparency other than opacity.

[0027] Thus if the area to be adjusted is a menu area, the screen menu displayed on the display screen has certain transparency without shielding all the displayed external video signals, thus improving the experience of a user.

[0028] FIG. 2 is a schematic diagram of a screen menu, and as can be apparent from FIG. 2, a menu displayed according to screen menu data typically includes two areas, i.e., an area A defined by the white line, and an area B beyond the white line, where the area A is different from the area B in that there are menu options and the background in the area A, and there is only the background in the area B. Thus the color of the background in the area A can be set to a first color so as to define the area A as a first area to be adjusted, and the color of the background in the area B can be set to a second color so as to define the area B as a second area to be adjusted, whereby a method for setting transparency of a screen menu according to an embodiment of the present application includes the following steps as illustrated in FIG. 3:

[0029] In the step S101, the screen menu data is received.

[0030] In the step S301, the transparency of a first area to be adjusted in the received screen menu data is set as a first preset transparency, and the transparency of a second area to be adjusted in the received screen menu data are set to a second preset transparency, and a received external video signal is superimposed onto the screen menu data in which the transparencies has been set, and the superimposed data are output to a display screen for displaying, where both the first preset transparency and the second preset transparency are transparencies other than opacity.

[0031] Since there are menu options in the area A, the transparency of the area A, i.e., the first area to be adjusted in the screen menu data can be set to the first preset transparency which is a transparency other than total transparency and opacity, i.e., a semi-transparency, where the transparency is set to an Alpha value at levels 0 to 255 with 0 representing total transparency, and 255 representing opacity, so the Alpha value of the semi-transparency lies between 0 and 255. Since the area A is semi-transparent, a video displayed according to the external video signal can be seen through the area A.

[0032] Here since there are no menu options in the area B, the transparency of the area B, i.e., the second area to be adjusted in the screen menu data can be set to the second preset transparency which can be total transparency, so the video displayed according to the external video signal can be seen through the area B.

[0033] Here the first area to be adjusted is a menu area in the screen menu data, and the second area to be adjusted is an image area other than the menu area in the screen menu data.

[0034] If a method for setting transparency of a screen menu according to an embodiment of the present application is applied in reality, an application scenario of this method can be as illustrated in the schematic structural diagram in FIG. 4, where screen menu data can be output by a processor 41 of an audio and video playing device in any data format, e.g., the HDMI format, and On-Screen Display (OSD) data output by the processor 41 of the audio and video playing device can be converted by a data conversion chip 42 into OSD data that can be identified by a Frame Rate Conversion/Motion Estimation and Motion Compensation (FRC/MEMC) chip 44, and a video format conversion chip 43 can convert a received external video signal in any format into a video signal that can be recognized by the FRC/MEMC chip 44, for example, if the FRC/MEMC chip 44 can identify a video signal in the V-by-One format, the video format conversion chip 43 will convert a received external video signal in some format, e.g., the HDMI format, into a video signal in the V-by-One format, and output it to the FRC/MEMC chip 44. The FRC/MEMC chip 44 sets the transparency of an area to be adjusted in the received OSD data to a preset transparency, superimposes the external video signal converted in format by the video format conversion chip 43 onto the OSD data in which the transparency is set, and outputs the superimposed data to a display screen for displaying. Alternatively if the color of the background of a first area to be adjusted, i.e., a menu area, in the OSD data received by the FRC/MEMC chip 44 is a first color, and the color of the background of other area than the menu area, i.e., a second area to be adjusted, is a second color, the FRC/MEMC chip 44 will set the transparency of the first area to be adjusted in the received OSD data to a first preset transparency, and the transparency of the second area to be adjusted in the received OSD data to a second preset transparency, superimpose the external video signal converted in format by the video format conversion chip 43 onto the OSD data in which the transparencies of the background are set, and output the superimposed data to the display screen for displaying.

[0035] If a method for setting transparency of a screen menu according to an embodiment of the present application is applied in reality, an application scenario of this method can be as illustrated in the schematic structural diagram in FIG. 5, where screen menu data can be output by a processor 41 of an audio and video playing device in any data format, e.g., the HDMI format, and OSD data output by the processor 41 of the audio and video playing device can be converted by a data conversion chip 42 into OSD data that can be identified by a video format conversion chip 43. The video format conversion chip 43 sets the transparency of an area to be adjusted in the received OSD data to a preset transparency, superimposes a received external video signal onto the OSD data in which the transparency is set, and converts the video signal superimposed onto the OSD data into a video signal that can be identified by an FRC/MEMC chip 44. Alternatively the color of the background of a first area to be adjusted, i.e., a menu area, in the OSD data received by the video format conversion chip 43 is a first color, and the color of the background of other area than the menu area, i.e., a second area to be adjusted, is a second color, the video format conversion chip 43 will set the transparency of the first area to be adjusted in the received OSD data to a first preset transparency, and the transparency of the second area to be adjusted in the received OSD data to a second preset transparency, superimpose the received external video signal onto the OSD data in which the transparencies are set, and convert the video signal superimposed onto the OSD data into a video signal that can be identified by the FRC/MEMC chip 44. For example, if the FRC/MEMC chip 44 can identify a video signal in the V-by-One format, the video format conversion chip 43 will convert an external video signal in some format, e.g., the HDMI format, into a video signal in the V-by-One format, and output it to the FRC/MEMC chip 44. The FRC/MEMC chip 44 compensates for and output the received video signal to a display screen for displaying.

[0036] Here the processor of the audio and video playing device can be connected with an Ethernet module, a Wireless Fidelity (WiFi) module, a Bluetooth module, a power management module, a storage module, an audio system, etc.

[0037] That is, if the external video signal is superimposed by a chip onto the OSD data output by the processor of the audio and video playing device, the transparency of the area to be adjusted in the OSD data will be set by this chip. The external video signal above refers to a video signal output by an externally connected video signal source instead of a video signal output by the processor of the audio and video playing device.

[0038] Based upon the same inventive concept, an embodiment of the present application further provides an apparatus for setting the transparency of a screen menu, and since the apparatus addresses the problem under a similar principle to the method above for setting the transparency of a screen menu, reference can be made to the implementation of the method above for an implementation of the apparatus, and a repeated description thereof will be omitted here.
