Video playing system capable of generating line by line scanning and interlaced scanning visual signal together

Abstract

The invention relates to image playing system. It includes main frame processor, interleaved signal reconstruction module and view information coding module. The main frame processor is complied with the image signal transmitted from the image storage to generate the corresponding non-interlaced main frame signal. The non-interlaced main frame signal can be generated the non-interlaced format signal by the pre-determinate image processing program at the follow-up. The interleaved signal reconstruction module can be received the non-interlaced format signal, and used the parity interleaving temporary storage form to selectively store the non-interlaced format signal to gain it. The view information coding module is complied with the view information standard of the image display unit to code the non-interlaced format signal and the non-interlaced format signal each to the non-interlaced view information signal and the non-interlaced view information signal accorded with the view information standard of the image display unit. Thus the image display unit can supply the non-interlaced view information signal and the non-interlaced view information signal together to the corresponding image display unit to do image display.

Description

technical field [0001] The invention relates to an image playing system capable of generating progressive scan and interlaced scan video signals together. Background technique [0002] Known dynamic images are continuously played one by one, utilizing the persistence of vision of the human eye to generate the effect of dynamic images. The playback of each screen starts from the upper left of the screen, draws a horizontal line horizontally to the right, and then starts the next horizontal line. This is the "scanning line". For example, in the known NTSC standard, 525 scanning lines constitute a screen, and the effective scanning number of the screen is 483 lines. [0003] When an image display device such as a TV, a projector, or a computer screen plays an image, it can usually be divided into two scanning methods, one is an interlace scan technology, and the other is a progressive scan (progressive scan) technology. technology. Interlaced scanning technology has been dev...

Problems solved by technology

[0011] Compare image 3 and Figure 4 The video playback system 30 and figure 2 It can be seen from the embodiment of the video playback system 10 that when it is necessary to form a progressive scan video signal 31, the video playback system 30 does not need to use an external interlaced progressive conversion circuit 13, thereby reducing manufacturing costs, but the video playback system 30 only Can selectively play progressive video signal 31 or interlaced video signal 11, but cannot play both together
