Problems solved by technology

[0003] 1. The existing technology can only protect the block but not the pixel level. OSD can only be a simple figure composed of rectangles and cannot be a circle or an irregular shape (such as a square with rounded corners), otherwise it will Because the exact location of the OSD cannot be known, there is no way to fully protect the OSD during motion estimation / motion compensation processing;
[0004] 2. In the prior art, the location of the OSD is obtained through a transmission interface different from that of the Low Voltage Differential Signaling (LVDS) transmission interface. Different transmission interfaces have different frequencies and cause time gaps, so now Some OSDs cannot be moved, slid, scrolled or quickly changed shape;
[0005] 3. After two-dimensional (2D) to stereoscopic (3D) image processing, the OSD may be deformed and not within the predetermined protection range;
[0006] 4. The stereoscopic OSD cannot be fully protected in the stereoscopic frame sequential mode (Frame Sequential Mode), because the position of the OSD in each frame is different;
[0007] 5. The 3D OSD cannot be fully protected when changing the 3D Depth

Embodiment Construction

[0032] see figure 1 , which shows a system architecture suitable for executing the display method for displaying information on a screen proposed by the embodiment of the present invention. Such as figure 1 As shown, the LVDS transmitter 100 receives externally input image data and sends it to the data processor 102 for processing such as scaling (Scaling), image quality (Picture Quality, PQ), etc. to generate control information and display data, and the display data and control The information is sent to the LVDS transmitter 106, and then the LVDS transmitter 106 sends it to the LVDS receiver 120 through the LVDS transmission interface according to the LVDS transmission protocol. Here, the display data generated by the data processor 102 may include specific display content defined by control information, such as OSD, pointers to left and right eye images, pointers to multi-view images, sub-pictures of picture-in-picture, trademarks (Logo) or subtitles etc., and the contro...

Abstract

The invention relates to a display method for displaying information on screens. According to the method, display data and control information are generated. Then the display data and the control information are transmitted to a display device via the same transmission interface according to transmission protocols and the display device contains images containing specific display contents according to the control information. According to the invention, the control information and the specific display contents are transmitted via the same transmission interface so as to realize the pixel-level identification of the specific display contents. Therefore, the display content can be completely protected without being damaged.

Description

technical field [0001] The invention relates to the technical field of image data transmission, and in particular to a method for displaying information displayed on a screen. Background technique [0002] According to the existing motion estimation / motion compensation (Motion Estimation and Motion Compensation, MEMC) technology, because it is impossible to know whether the received image contains an on-screen display (On-Screen Display, OSD), it must be transmitted by the transmitter I2C bus and other transmission interfaces tell the position of the motion estimation / motion compensation chip OSD in the form of coordinates, and the motion estimation / motion compensation chip can use this to protect the OSD from being damaged due to motion estimation / motion compensation processing. The disadvantages of the technique are: [0003] 1. The existing technology can only protect the block but not the pixel level. OSD can only be a simple figure composed of rectangles and cannot be ...
