Motion compensation block diagram of frame rate converter 140 is respectively coupled to video format conversion bridge sheet 120, data transaction chip 130 and display screen 20, in order to receive the outer video signal after the main video signal after conversion or conversion from video format conversion bridge sheet 120, and based on motion detection and motion compensation (motionestimationandmotioncompensation, MEMC) principle carries out frame-rate conversion (framerateconversion to the outer video signal after the main video signal after conversion or conversion, FRC), thus the outer video signal after the main video signal after conversion or conversion is treated to high-resolution and high frame-rate video signal, the video content of 120Hz or 240Hz refresh rate is such as risen to from the video content of common 60Hz refresh rate, then this high-resolution and high frame-rate video signal are sent to display screen 20 to play, thus improve the readability of motion picture.
What deserves to be explained is, in motion compensation block diagram of frame rate converter 140 also in order to receive screen display menu data from data transaction chip 130, and received screen display menu data are superposed with the outer video signal after conversion, and in overlap-add operation, can be superposing of the outer video signal after first carrying out screen display menu data and changing, and then the outer video signal being superimposed with screen display menu data is treated to high-resolution and high frame-rate video signal; Or after the outer video signal after conversion is treated to high-resolution and high frame-rate video signal, then carry out the superposition of screen display menu data.Below the order being only overlap-add operation is different, and can produce the high-definition screen presented on display screen 20 with screen display menu data, and therefore above-mentioned overlay order is also not used to limit the utility model.
Below by way of the function mode for example explanation of an embodiment to the playing audio/video 10 disclosed by the utility model embodiment.
After the processor 110 of playing audio/video 10 receives audio-video signal from master source 30, pass through I
2the audio signal in S audio-frequency bus autonomic signals source 30 in future is sent to audio system 40; And be sent to data transaction chip 130 by the main video signal in the first video format output interface 112 autonomic signals source in future.In the process, processor 110 can also produce corresponding screen display menu data according to received peripheral operation instruction by screen display menu functional module 111, and these screen display menu data are superposed with main video signal, and then the main video signal being superimposed with screen display menu data is sent to data transaction chip 130; Or individually screen display menu data are sent to data transaction chip 130.And, in the transport process of main video signal, the Data Format Transform of vision signal is optionally the data format being applicable to the first video format output interface 112 by processor 110 according to the actual requirements, such as HDMI, and then be sent to data transaction chip 130 by the first video format output interface 112.
Data transaction chip 130 is sent to video format conversion bridge sheet 120 by signal output interface 132 after receiving the main video signal after main video signal or superposition by signal input interface 131.And video format conversion bridge sheet 120 by the first video format input interface 121 receive above-mentioned main video signal or superposition after main video signal after, it is carried out to the conversion of data format, such as from HDMI Data Format Transform be V-by-One data format, then by the second video format output interface 123 by conversion after main video signal be sent to motion compensation block diagram of frame rate converter 140.
Then, after main video signal after receiving conversion by the second video format input interface 141, motion compensation block diagram of frame rate converter 140 carries out motion detection, motion compensation and frame-rate conversion to the main video signal after conversion, makes the main video signal after conversion be treated to high-resolution and high frame-rate video signal.Then, this high-resolution and high frame-rate video signal are sent to display screen 20 and play, thus present high-definition screen on display screen 20.
In addition, when the audio-video signal inputting playing audio/video 10 is the outside source coming from the audio frequency and video such as DVD player or Set Top Box output equipment, this outside source is coupled to video format conversion bridge sheet 120 by outside audio frequency and video input interface 124, so that outside audio-video signal is sent to video format conversion bridge sheet 120 by outside audio frequency and video input interface 124.
Then, the external audio signal from outside source is sent to processor 110 by the audio output interface 125 of video format conversion bridge sheet 120, then is provided to audio system 40 by processor 110 and plays.And carried out the conversion of data format by video format conversion bridge sheet 120 from the outer video signal (vision signal in the audio-video signal of namely outside source) of outside source, such as, be V-by-One data format from HDMI Data Format Transform, it is made to meet the output format of the second video format output interface 123, and then by the second video format output interface 123, the outer video signal after conversion is sent to motion compensation block diagram of frame rate converter 140, so that carry out high-resolution and/or high frame per second process.Such as, if the resolution of this outer video signal has been highest resolution, do not carry out the process of resolution in the case, otherwise, if not highest resolution, be then treated to highest resolution.Such as, when the outer video signal of input has 4K*2K resolution, then do not process; If the outer video signal of input only has the resolution of 1080P, be then treated to 4K*2K resolution.
Now, be sent to the process of motion compensation block diagram of frame rate converter 140 at outer video signal from video format conversion bridge sheet 120, if when processor 110 receives the operational order from outside and produces corresponding screen display menu data by screen display menu functional module 111, these screen display menu data are sent to data transaction chip 130 by the first video format output interface 112 of processor 110, and in data transaction chip 130, carry out the conversion of data format, the data format that the menu Data Input Interface 142 its data format being converted into meet motion compensation block diagram of frame rate converter 140 can receive, then, motion compensation block diagram of frame rate converter 140 is sent to by the menu data output interface 133 of data transaction chip 130.Be understandable that, if when the data format that namely the primary data form of screen display menu data can receive with the menu Data Input Interface 142 of dynamic compensated frame rate converter 140 conforms to, can the operation of omitted data format conversion.
