Abstract
The invention belongs to the technical field of video conversion systems and particularly relates to a high-definition video conversion system. The high-definition video conversion system is low in cost, easy to achieve and convenient to upgrade software and hardware. The high-definition video conversion system comprises a video player, an HDMI (High-Definition Multimedia Interface) receiver, an FPGA (Field Programmable Gate Array), a display panel and a video buffer unit. The structural key points of the high-definition video conversion system are that the FPGA is connected with the HDMI receiver, the display panel and the video buffer unit; and the HDMI receiver is connected with the video player.
Description
Technical field
the invention belongs to video conversion system technical field, relate in particular to a kind of HD video converting system.
Background technology
3D shows that (stereo display) is considered to the main flow Display Technique of future generation after high definition shows.In fact,, from 2010,3D shows that product has been full of consumer electronics market rapidly.But the disunity of 3D television video transformat becomes the main obstruction of 3D TV market development for a long time.HDMI1.4a standard is the digital facility interface standard that HDMI association issued in March, 2010, than early version, the change of redaction maximum is exactly the support having added 3D video format, especially the explanation of mandatory 3D television video form is laid a good foundation for the video format unification of 3D TV market especially.Existing HD video converting system cost is high, realization is difficult, software and hardware upgrade is all inconvenient.
Summary of the invention
the present invention is exactly for the problems referred to above, provide a kind of cost low, realize easily, all HD video converting systems eaily of software and hardware upgrade.
to achieve these goals, the present invention adopts following technical scheme, the present invention includes video playback apparatus, HDMI receiver, FPGA, display floater, video buffer unit, its structural feature FPGA is connected with HDMI receiver, display floater, video buffer unit respectively, and HDMI receiver is connected with video playback apparatus.
as a kind of preferred version, HDMI receiver of the present invention adopts ADV7612 chip.
as another kind of preferred version, video buffer of the present invention unit adopts SDRAM.
beneficial effect of the present invention.
the 3D video conversion system that meet HDMI1.4a standard of the present invention take FPGA as core, has proposed to be applicable to based on active picture DIF the video conversion plan of interlacing scan 3D display.Cost of the present invention is low, realization is easy, software and hardware upgrade is all more convenient.
Accompanying drawing explanation
in order to make technical problem solved by the invention, technical scheme and beneficial effect clearer, below in conjunction with the drawings and the specific embodiments, the present invention is further elaborated.Should be appreciated that embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
fig. 1 is schematic block circuit diagram of the present invention.
Embodiment
as shown in the figure, the present invention includes video playback apparatus, HDMI receiver, FPGA, display floater, video buffer unit, FPGA is connected with HDMI receiver, display floater, video buffer unit respectively, and HDMI receiver is connected with video playback apparatus.
described HDMI receiver adopts ADV7612 chip.
described video buffer unit adopts SDRAM.
the present invention is by the 3D video file of HDMI1.4a interface receiving set up box or Blu-ray player transmission, input is 3D video flowing (the TMDS signal of high definition level (1080 or 720p), meet HDMll.4a standard), output is picture exchange 3D form after treatment, still sends by LVDS interface with TMDS signal form.
the 3D video format of HDMI1.4a definition has tens of kinds more than, but at present popularly on the market mainly contain seven kinds, these seven kinds of forms have been contained the equipment such as Blu-ray player, PS3 game machine, PC, Set Top Box, have met the requirement that builds 3D digital home 100 audio-video systems completely.The present invention is mainly for being applied to the Side-By-Side of field of broadcast televisions and Top-And-Bottom video format and studying for the conversion of the Frame packing 3D video format of blue light player.
3D format video conversion thinking: first, the parallel video data that HDMI receiver is sent are processed, export respectively left and right frame of video, realize the conversion of other resolution to 1920 × 1080 pixels by row/column difference, video data after conversion completes by the operation of the control of FPGA internal storage and memory address the interleaved output video stream translation of lining by line scan, finally by output frequency multiplication, the video of non-60Hz frame per second is converted to monocular 60Hz, the frame refreshing frequency of binocular 120Hz, reaches good video display effect.
in real work, the height of high frame frequency image processes bandwidth and large storage demand often needs to combine consideration, and the selection that embodies a concentrated reflection of plug-in buffer memory is upper with design, and more ripe scheme has SRAM, SDRAM, DDR, DDR2, DDR3 etc., wherein DDR3 has the highest interface bandwidth and storage depth, consider concrete condition and requirement cheaply, the present invention adopts SDRAM as video cache, can meet the requirement of high speed image treatment system to high interface bandwidth and large capacity storage.System adopts external HDMI interface chip and built-in LVDS interface module to carry out transfer of data, uses SDRAM as video buffer unit.
be understandable that, above about specific descriptions of the present invention, only for being described, the present invention is not limited to the described technical scheme of the embodiment of the present invention, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the present invention, to reach identical technique effect; Use needs as long as meet, all within protection scope of the present invention.
