Example Embodiment

[0045] see Figure 5 , Figure 5 It is a block diagram of the video playing system 50 of the present invention. The video playback system 50 includes a main picture processor 52 , an auxiliary picture processor 54 , a mixer 56 , a pre-processor 58 , an interlaced signal generation module 60 and a video encoding module 62 . The auxiliary picture processor 54 includes a sub picture decoder 66 and a video control display menu processor 68 . The front-end processor 58 includes a low-pass filter 72 , a brightness adjuster 74 , a hue adjuster 76 and a contrast adjuster 78 .

[0046] The image playing system 50 is used for generating a progressive video signal 31 and an interlaced video signal 11 together to at least one image display device for image display.

[0047] like Figure 5 As shown, the main picture processor 52 can generate a corresponding progressive main picture signal 80 according to the video signal 22 transmitted from the video memory 20 . If the video signal 20...

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...
