Abstract

Embodiments of the disclosure provide a method and apparatus for setting the transparency of an on-screen display so as to address the drawback in the prior art of impossibility to transmit Alpha data in a data transmission format in which transmission of the Alpha data is not supported. The method includes: a data transmitter and a data receiver preset data bits in which Alpha data are transmitted; the data transmitter transmits OSD data including the Alpha data transmitted in the preset data bits to the data receiver; the data receiver receives the OSD data and identifies the Alpha data transmitted in the preset data bits, to the OSD data.

Claims

1. A method for setting the transparency of an on-screen display, OSD, comprising:

presetting data bits in which Alpha data are transmitted;

transmitting OSD data which comprises the Alpha data transmitted in the preset data bits;

receiving the OSD data;

identifying the Alpha data transmitted in the preset data bits, in the OSD data; and

setting the transparency of the on-screen display according to the Alpha data.

2. The method according to claim 1, wherein the transmitting the OSD data comprises:

transmitting the OSD data using RGB data bits..

3. The method according to claim 2, wherein the Alpha data are transmitted using any two data bits among data bits for each component in the RGB data.

4. The method according to claim 1, further comprising:

superimposing the OSD data for which the transparency of the on-screen display is set, onto a received external video signal, and transmitting them to a display screen for displaying.

5. The method according to claim 1, wherein the transmitting the OSD data comprises:

transmitting the OSD data with the HDMI protocol.

6. An apparatus for setting the transparency of an on-screen display, OSD, comprising:

at least one processor; and

a memory communicably connected with the at least one processor for storing instructions executable by the at least one processor, wherein execution of the instructions by the at least one processor causes the at least one processor to;

preset data bits in which Alpha data are transmitted;

transmit OSD data which comprises the Alpha data transmitted in the preset data bits;

receive the OSD data;

identify the Alpha data transmitted in the preset data bits, in the OSD data; and

set the transparency of the on-screen display according to the Alpha data identified.

7. The apparatus according to claim 6, wherein that transmit the OSD data comprises:

transmitting the OSD data using RGB data bits.

8. The apparatus according to claim 7, wherein the Alpha data are transmitted using any two data bits among data bits for each component in the RGB data.

9. The apparatus according to claim 6, wherein the at least one processor is further caused to superimpose the OSD data for which the transparency of the on-screen display is set, onto a received external video signal, and to transmit them to a display screen for displaying.

10. The apparatus according to claim 6, wherein that-transmit the OSD data comprises:

transmitting the OSD data with the HDMI protocol.

11. A non-transitory computer-readable storage medium storing executable instructions that, when executed by an apparatus, cause the apparatus to:

preset data bits in which Alpha data are transmitted;

transmit on-screen display, OSD, data which comprises the Alpha data transmitted in the preset data bits;

receive the OSD data;

identify the Alpha data transmitted in the preset data bits, in the OSD data; and

set the transparency of the on-screen display according to the Alpha data identified.

12. The non-transitory computer-readable storage medium according to claim 11, wherein that transmit the OSD data comprises:

transmitting the OSD data using RGB data bits.

13. The non-transitory computer-readable storage medium according to claim 12, wherein the Alpha data are transmitted using any two data bits among data bits for each component in the RGB data.

14. The non-transitory computer-readable storage medium according to claim 11, further cause the apparatus to:

Superimpose the OSD data tor which the transparency of the on-screen display is set, onto a received external video signal, and transmitting them to a display screen for displaying.

15. The non-transitory computer-readable storage medium according to claim 11, wherein that transmit the OSD data comprises:

transmitting the OSD data with the HDMI protocol.
