The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Embodiment 1

First of all, it should be noted that the moving picture that people see through the display screen is actually a static image with a certain relationship displayed by a certain refresh frequency. Usually, the "frame" is used as the unit of the image, that is, one. The image corresponds to one video frame. Since the human eye has a "visual persistence" function, when a plurality of discrete video frames are displayed at a certain frequency, a continuous moving picture can be seen. When the active screen is actually displayed on the display, the display frequency of the video frame is determined by the refresh rate of the display. Each time the display is refreshed, a new video frame can be displayed.

For example, in order to ensure the consistency of the active picture display, the display refresh rate is 60 frames / sec, that is, the display refreshes 60 times per second, and the refresh cycle is 1/60 seconds. Of course, with the continuous development of science and technology, it is also possible to increase the refresh rate of the display screen to display a picture with better dynamic characteristics. For example, the current display screen has achieved a refresh rate of 120 frames/second or 240 frames/second. .

The present inventors have found in the course of realizing the present invention that a display screen having a high refresh rate can realize that a plurality of moving pictures are refreshed at a lower speed from time. For example, a 240 frames per second screen can be used to instantly refresh 4 active frames at 60 frames per second. Therefore, in the embodiment of the present invention, the display screen is divided into time divisions, so that the technical basis for realizing multiple people simultaneously viewing different video images through the same display screen can be provided. For example, on the basis of this, an external device such as a time-controlled sunshade can be combined to select a desired image, so that multiple people can simultaneously view different video images through the same display.

Therefore, in the first embodiment of the present invention, a video picture display processing apparatus is firstly provided. Referring to FIG. 3, the apparatus includes the following units: The video picture sending unit 301 is configured to send the plurality of video pictures from different video sources to the display screen display; the sum of the refresh speeds of the plurality of pictures from different video sources is equal to the refresh speed of the display screen;

The first thing to note here is that, when the video screen is displayed, the video screen displayed by the same display screen is one. The specific process may be that the main chip of the display reads the corresponding video frame from the video source into the memory. Then, the read video frame is displayed on the screen, that is, output to the display for display. The frequency at which the main chip reads the video frame from the video source is the same as the refresh rate of the display screen. For example, when the display refresh rate is 60 frames/second, the main chip reads the video from the video source at a rate of 60 frames/second. Frame, that is, one video frame is read every 1/60th of a second.

In the first embodiment of the present invention, a picture of multiple video sources needs to be displayed on the same display screen. To achieve this, in a specific implementation, a read period may be first determined, and videos of multiple video sources are read in the read period. The frame, and the video frames of the plurality of read video sources are sent to the display for display. The read cycle may be determined jointly according to the refresh frequency of the display screen and the number of video sources that need to be simultaneously displayed through the display screen. For example, the refresh rate of the display is 240 frames per second, and the number of video sources that need to be displayed simultaneously through the display is 4, and the reading period is 1/60 seconds. That is, 4 video frames from 4 different video sources need to be read every 1/60 second.

It can be seen that the read cycle can be an integer multiple of the display refresh cycle and the multiples are the same as the number of video sources that need to be displayed simultaneously through the display. Of course, in practical applications, the read cycle can also be determined in other ways.

It should be noted that, for a television set, the video source may be a signal source of each television channel, and in practical applications, it may be obtained from a tuner or a set top box. Since it is required to read video frames of a plurality of video sources in the same reading period, in the process of implementing the embodiments of the present invention, the television set may be configured with a plurality of high frequency heads or set top boxes to simultaneously signal the plurality of television channels. Decoding is performed to obtain video frames of multiple channels. That is, assuming that it is necessary to display a television screen of four channels through the same display screen, the television set can have four high frequency heads, or four set top boxes.

When the video picture is displayed as described above, the active picture from multiple video sources can be displayed on the same display screen. Of course, since the video frames of different video sources may be interlaced, and different videos There is no correlation between the video frames of the source, so if viewed directly with the naked eye, the exact image content may not be resolved. However, the above has been processed for the next step. Providing a technical basis, as long as a certain technical means can be used to distinguish the video frames of the respective video sources displayed on the display screen, it is possible to realize that multiple people simultaneously watch video images of different video sources on the same display screen.

In a preferred embodiment of the invention, the viewer can be viewed through an external device consisting of a material that can be controlled to be light transmissive or opaque. That is, the external device is made of a special material (such as a liquid crystal material, etc.), and can be controlled by a signal to transmit light or opaque, or when to transmit light, when it is opaque, etc.; The video source is separated. At this time, the video picture display device provided by the embodiment of the present invention further includes the following units:

The synchronization signal sending unit 302 is configured to respectively issue a synchronization signal with video source information when video images from different video sources are displayed on the display screen.

The synchronization signal is used as an identification information, so that the external device can distinguish which video source of the video source is displayed on the current display screen, and perform light transmissive or opaque switching according to the video source identifier. In this way, the video images of different video sources displayed on the same display screen can be separated, so that for a particular user, only the video images from one video source are seen, and the video images are certain. The refresh rate is displayed on the display to form an active picture.

In order to better realize, the video images of multiple video sources are displayed on the same display screen, and the video frames of the respective video sources can be processed before the read video frames are sent to the display screen. For example, the device may further include:

An interpolation processing unit is configured to perform frame interpolation processing before transmitting video images from different video sources to the display screen.

Of course, in order to facilitate the frame insertion process of the read video frame, the video frames of the multiple video sources read in the same read cycle may be into the memory, and then the read video frames are read in the memory. Perform frame interpolation processing; wherein, in the same read period, only one frame is read for video frames of the same video source.

It should be noted that, in order to implement the embodiments of the present invention, multiple video frames may need to be stored in the memory. For example, if it is required to simultaneously display 4 active pictures, it is necessary to temporarily store 4 video frames in the memory, 4 Video frames may require a large amount of storage space, but this does not affect the normal processing of the main chip.

That is, multiple video frames can be read into the memory during the same read cycle, where storage The video frames in the device respectively correspond to different video sources, and the video frames are interpolated before being displayed on the screen. In other words, the video frames are interlaced. There may be a plurality of specific frame interpolation processing methods, and one of the implementations is exemplarily described herein, and is not intended to limit the present invention.

For example, suppose the four video sources are &, b, c, and d, respectively. The respective video frame sequences are al, a2, a3, ..., bl, b2, b3, ..., cl, C2, c3... ... , dl, d2, d3 ... ... , according to the foregoing scheme, the video frames read in the first read cycle are al, bl, cl, dl, and then The video frames are interlaced, for example, the order of the interlace coding is a, b, c, d, and the encoded video frames are al, bl, cl, and dl; of course, other interleaved coding sequences may also be used. , such as encoding as al, cl, bl, dl, etc. It can be seen that the process of interpolating or interleaving the video frames in the memory is equivalent to the process of reordering.

Since the video frames in the memory have been reordered, each video frame is sequentially outputted to the display screen in order. Of course, the frequency of the video frame can be equal to the refresh rate of the display. For example, when the display refresh rate is 240 frames/second, a video frame is output to the display every 1/240 second.

Then, the video frame of the next read cycle is continued, wherein the read period is unchanged. For example, if it is still assumed that video frames of four video sources need to be read, the video frames read in the second read cycle are respectively a2, b2, c2, and d2, and then the video frames are also followed by the first cycle. The same interleaved coding sequence is interleaved and displayed on the screen. Similarly, the video frames read during the third read cycle are a3, b3, c3, d3, and so on. Thus, the video frames finally displayed on the display screen are, for example, al, bl, cl, dl, a2, b2, c2, d2, a3, b3, c3, d3, ... where each video frame is between The display time interval is the refresh period of the display screen, and the display time interval between the video frames of the same video source is the read period in the first embodiment of the present invention.

Of course, the video frames that have been output to the display can be deleted from the memory to avoid taking up too much storage space. That is, for the case where it is necessary to simultaneously display four moving pictures, up to four video frames are simultaneously stored in the memory.

It can be seen from the above that the apparatus according to the embodiment of the present invention may further include a decoding unit and a storage unit, where the decoding unit is configured to perform decoding processing on video pictures from different video sources, and send the data to a storage unit; Different video pictures after decoding processing are read and stored in turn, and sent The frame interpolation processing unit performs frame insertion processing.

It should be noted that in practical applications, the refresh rate of the display screen is different due to the difference in the television system. For example, in the PAL (Phase Alternating Line) system, the display refresh rate is a multiple of 50. For example, there is usually a display screen with a refresh rate of 100 or 200 frames/second. The frame processing may be 100/200 Hz frame interpolation processing. Correspondingly, the refresh rate of the pictures of the different video sources is 50 frames/second. That is to say, for a display screen with a refresh rate of 100 frames/second, 100 Hz frame interpolation processing is performed, and at this time, the screen refresh speed of a single video source can be 50 frames/second, and therefore, only the display can be passed. The screen plays video images of two video sources; for a display screen with a refresh rate of 200 frames/second, 200 Hz frame interpolation processing is performed, and at this time, the screen refresh speed of a single video source can also be 50 frames/second ( As long as the visual pause requirement is met, the video screen of the four video sources can be played through the display screen.

Similarly, in the NTSC (National Television System Committee) system, the refresh rate of the display screen is a multiple of 60. Therefore, the frame interpolation process can also be 120/240 Hz frame interpolation processing, correspondingly, The refresh rate of the pictures of the different video sources is 60 fields/second. That is to say, for a display screen with a refresh rate of 100 frames/second, a frame insertion process of 120 Hz is performed, and at this time, the picture refresh rate of a single video source can be 60 frames/second, and therefore, only the display can be performed. The screen plays video images of two video sources; for a display screen with a refresh rate of 240 frames/second, performing 240 Hz frame interpolation processing, at this time, the screen refresh rate of a single video source can also be 60 frames/second. Therefore, video images of four video sources can be played through the display screen.

In the specific implementation, the external device may be a special type of glasses, which can receive a synchronization signal sent by the main chip of the television, and display the screen in a specific cycle. Therefore, the viewer can Choose the picture you need by wearing this special pair of glasses. In a specific implementation, a synchronization signal may be sent by the main chip to sequentially indicate which video data is currently output. For example, if the video frame currently outputted to the display screen is a1, a2, a3, etc., the corresponding signal is issued. The identification signal of the video source identifier a, the glasses receive the identification signal, and the specific video source identifier can be analyzed therefrom, and then according to the video source identifier and the video source identifier set by the user, whether the current light transmission is determined. For example, if the video source identifier set by the user A is a, the light is transmitted when the identification signal with the video source identifier a is received. Otherwise, if the identification signal of the video source identifiers b, c, and d is received, It is opaque. Thus, for user A's glasses, only when the display When the video frames a1, a2, a3, ... of the video source a are displayed, the light will be transmitted, and the video frames of other video sources are opaque, so the user A can only see the video source a. The video frames a1, a2, a3... Of course, for the user B who is located in front of the display, the screen of the video source b can be selected for viewing, and for the glasses worn by the user B, it can be displayed only. The screen displays the video frames bl, b2, b3, ... of the video source b. The same reason, the user B only sees the video frames bl, b2, b3 of the video source b...

In practical applications, a synchronization signal can be sent every time a video frame is displayed on the display to indicate the video source of the video frame. Of course, since the display time interval between each video frame of the same video source is fixed, it is equal to the read period. Therefore, instead of displaying each video frame, the corresponding video source identifier may be issued. The identification signal, but only the synchronization signal is issued when the first video frame of each video source is displayed, and then automatically timed by the external device to keep synchronized with the refresh of the display.

It should be noted that, as described above, the display time interval between video frames of the same video source is a read period, for example, when the read period is 60 frames/second, for each user, each seen The active pictures of the video sources are all refreshed at 60 frames per second. In other words, four normal frames of 60 frames per second are displayed on the same display. In practical applications, if you want to make the dynamic characteristics of each screen display better, you can also display two active frames of 120 frames per second with a 240 frame/second display. Of course, as technology advances, the refresh rate of the display may increase further, so the number of video sources that can be simultaneously displayed may also increase.

In order to better understand the technical solution provided by the embodiment of the present invention, a more vivid introduction will be made by taking two active pictures simultaneously as an example.

Referring to FIG. 4, it is a schematic diagram when two active pictures are simultaneously displayed on the same display screen. Wherein, since only the video frames of the two video sources are assumed to be the video source a and the video source b, respectively, the order of the video frames displayed on the display screen is al, bl, a2, b2, ... The odd frames are the video frames of the video source a, and the even frames are the video frames of the video source b. For the user A and the user B, if the user A needs to view the video source a, the lenses of the glasses are equivalent. Only through odd frames, if user B needs to view the picture of video source b, the lens of the glasses is equivalent to only transmitting even frames.

It can be seen that, by using the device provided by the embodiment of the present invention, the display screen is divided into time divisions, so that different users can simultaneously see different pictures from the same display screen, and each user sees The pictures are displayed in full screen and will not be disturbed by other pictures.

Finally, it should be noted that, in the embodiment of the present invention, only the display of the video picture is considered. For multimedia data such as a television signal, in addition to the video, the audio signal is synchronized with the video, and if there is a sound for listening to each television program, The respective audio signals can be output from different channels, and the viewer can wear the headphones and listen to the corresponding channels. Since the processing of the audio data is not the main content of the embodiment of the present invention, it will not be described herein.

Embodiment 2

Corresponding to the video picture display processing device provided in the first embodiment of the present invention, the second embodiment of the present invention further provides a video picture display processing system. Referring to FIG. 5, the system includes the video picture processing device according to the first embodiment. 501, further comprising: a display screen 502 and a corresponding plurality of glasses 503, wherein:

The display screen 502 is configured to receive a plurality of video frames from different video sources from the video screen display processing device, and display corresponding video images;

There may be a plurality of glasses 503 that respectively receive the synchronization signal and maintain the same refresh rate as the video screen of the received synchronization signal.

The video source in the embodiment of the present invention may include at least one television channel signal source. The sync signal can be sent from the pointing device of the display.

The refreshing of the glasses includes switching the light or the opaque light after the glasses receive the synchronization signal. That is, when the synchronization signal is received to display the video source information of the current video picture, it is determined whether the light is transmitted according to the video source information. In practical applications, the glasses may be made of a liquid crystal material, and other materials capable of achieving this function may be used.

For the specific implementation of the second embodiment, refer to the description of the first embodiment, and details are not described herein again. Embodiment 3

Corresponding to the first embodiment and the second embodiment of the present invention, the third embodiment of the present invention further provides a video picture display processing method. Referring to FIG. 6, the method includes the following steps:

S601: Display a plurality of video images from different video sources, the display screen refresh speed is a sum of refresh speeds of the plurality of video images from different video sources, and the video source includes at least one television channel signal source;

S602: when the video images from different video sources are displayed, respectively, sending a video source letter a synchronization signal; wherein the synchronization signal can be sent through a pointing device of the display screen;

S603: The plurality of glasses respectively receive the synchronization signal and maintain the same refresh rate as the video screen of the received synchronization signal.

Among them, the frame insertion process can be performed before the pictures from different video sources are displayed. The interpolation processing may be 100/200 Hz frame interpolation processing, and correspondingly, the refresh rate of the pictures of the different video sources is 50 frames/second. Alternatively, the frame insertion process may also be 120/240 Hz frame interpolation processing, and correspondingly, the refresh rate of the pictures of the different video sources is 60 frames/second. In order to facilitate the interpolation processing, the following steps may be included before the interpolation processing:

The video signals of the respective video sources are decoded, and the decoded video frames of the respective video sources are read and stored in turn. That is, the read video frame is cached first, and then processed and then sent to the display screen for display. Of course, in order to save the cache space, after a video frame is sent to the display, the video frame will no longer be saved in the cache.

Similarly, the refreshing of the glasses includes switching the light or the opaque light after the glasses receive the synchronization signal. That is, when the synchronization signal is received to display the video source information of the current video picture, it is determined whether the light is transmitted according to the video source information. In practical applications, the glasses may be made of a liquid crystal material, and other materials capable of achieving this function may of course be used.

Referring to FIG. 7, which is a schematic diagram of a specific implementation process of the embodiment of the present invention, it can be seen that the video frames of each video source are read in turn, written into the memory for interlaced coding, and then the interlaced code is sequentially extracted by the refresh frequency of the display screen. Each video frame is output to the display.

In order to facilitate the viewer to distinguish the pictures of the video sources, the method may also send an identification signal carrying the video source identifier to the external device while outputting the video frame of the video source, so that the external device is configured according to the video source. Mark the switch for light transmission or opacity.

That is, from the viewer, it is only necessary to select one of the four video contents to view. To this end, the video processing main chip can issue a synchronization signal, which in turn indicates that the current output is the data of the video source, and the external device receives the data, and according to the viewer's selection, the selected image is selected in a specific cycle, and the data can be allowed. Multiple people simultaneously watch different active video programs on one display. This external device is realized by a special type of spectacles which is a material which can be controlled to transmit light or opaque, such as liquid crystal material. Such glasses can be synchronized with the screen refresh of the display screen by communication with the display device. Glasses can be used to automatically time the circuit or display on the screen There are indicators associated with the synchronization to achieve synchronization. In this way, one of the plurality of active pictures can be selected to remain transparent, and the remaining time is opaque, thus enabling multiple people to simultaneously view different video picture content through the same display screen.

In order to avoid excessive storage space occupied by video frames stored in the memory, after a video frame is output to the display screen, the corresponding video frame can be deleted from the memory.
