The video playback method for a viewing device and the respective steps thereof provided in this specification will be described in detail below.
It should be noted that the video playing method is suitable for the user to use the viewing device for viewing the video, such as viewing glasses, VR glasses, and the like.
Example one
Referring to fig. 1, a schematic step diagram of a video playing method for a viewing device according to an embodiment of the present disclosure is shown. It should be understood that the method is applied to the video receiving side of the viewing device, and controls the selective receiving of the video by the viewing device, so that different viewers using different viewing devices can view the video according with the requirements of the viewers. Therefore, the video playing method performed at the video receiving side includes the steps of:
step 10: when the same playing device alternately plays at least a first video and a second video, at least respectively controlling a first watching device to correspondingly receive the first video and a second watching device to correspondingly receive the second video;
the video playing is most thought of as movies, the current movie industry is well developed, the number of movie works on the market at the same time is not enough, but the preferences of different groups for movie works with different subjects are different, or the movie works or pictures are limited by age and are not suitable for watching some subjects.
The video playing method applied to the viewing device at the video receiving side provided by the embodiment of the present specification is suitable for the video playing side to play at least a first video and a second video, such as the first video, the second video, … …, nth video, which are different, at the same time period by using the same video playing device, and aims to reduce the number of video playing devices, the video playing time and the playing place, and particularly greatly save the time cost and the cost of the operating place for a cinema place, besides meeting the viewing requirements of different viewers using different viewing devices. It should be noted that, the same video playing device completes playing each video in the time period, and plays different contents in different videos at different time points in the time period, where the content may be at least 1 frame, or a frame group composed of multiple frames, so as to ensure that the viewer views a smooth picture.
In this step, when the same playing device alternately plays different videos, the first watching device is controlled to correspondingly receive the first video, the second watching device is controlled to correspondingly receive the second video, … …, the nth watching device is controlled to correspondingly receive the nth video, and n is greater than or equal to 2.
It should be appreciated that the first viewing device receives only the first video, the second viewing device receives only the second video, … …, and the nth viewing device receives only the nth video, such that a viewer using the same viewing device can always view the same video received by the viewing device.
In addition, each viewing device may receive the corresponding video and then display the video to the viewer using the corresponding viewing device, or each viewing device may receive the corresponding video and then directly display the video to the viewer using the corresponding viewing device. That is, after receiving the corresponding video, each viewing device may perform other processing on the video and then display the video to the viewer using the viewing device, or each viewing device may directly display the video to the viewer using the viewing device after receiving the corresponding video.
It should be noted that, in the embodiment of this specification, the same playing device alternately plays different contents in at least a first video and a second video, the first viewing device receives the first video when playing the first video, the second viewing device receives the second video when playing the second video, … …, the nth viewing device receives the nth video when playing the nth video, and then the first viewing device receives the first video when playing the first video, such that the alternation is cyclic and may be regular or irregular, in order to ensure that different viewers using the respective viewing devices can view smooth videos, the time for playing the respective videos by the same playing device is short, and the time is short enough for the same playing device to be invisible to naked eyes.
Step 20: and at least respectively controlling the first viewing device to display the first video and the second viewing device to display the second video.
It should be understood that after the first viewing device receives the first video and the second viewing device receives the second video, … …, the nth viewing device receives the nth video, and then performs other processing on the content of the videos and displays the processed content to the viewer using the viewing device, for example, the first viewing device performs 3D processing on all the content of the first video received in the time period and displays the processed content in 3D effect to the viewer using the first viewing device.
In the embodiment of the description, different watching devices receive corresponding video contents and then display different videos on different watching devices, so that different groups can meet respective watching requirements by using different watching devices in the same time period, for example, in the same projection hall of a movie theater, in the midnight time period, due to less audiences, audiences who purchase different movie and television works can be concentrated on one projection hall and then watch movie videos to be watched by using different watching glasses. Such as the case of one television at home, dad, mom and children can watch football, drama and animation on that television at the same time.
According to the technical scheme, the processing that different videos need to be watched simultaneously can be completed, the processing of the audio in different movie and television works needing to be played by the same playing device can keep mutually independent audio, when the same playing device alternately plays at least a first video and a second video, the audio of the first video can be sent to the first watching device through a wireless transmission technology such as Bluetooth or Wifi, and the audio of the second video can be sent to the second watching device through the wireless transmission technology.
In some embodiments, at least the first viewing device and the second viewing device respectively include a lens for a user to view a video, and in a video playing method for the viewing devices provided by the embodiments of the present specification, step 10: at least respectively controlling a first watching device to correspondingly receive a first video and a second watching device to correspondingly receive a second video, specifically comprising:
and respectively and alternately controlling the light transmittance of the lens of at least the first viewing device and the light transmittance of the lens of the second viewing device so that the at least first viewing device correspondingly receives the first video and the second viewing device correspondingly receives the second video.
Viewing devices such as viewing glasses are usually provided with lenses, and users can view videos played by the playing devices through the lenses, and the lenses can realize 3D effects or other effects. In a video playing method for a viewing device provided in an embodiment of the present specification, in implementation step 10: when the first watching equipment is controlled to correspondingly receive the first video and the second watching equipment is controlled to correspondingly receive the second video, the lens of the watching equipment can be light-permeable to receive the corresponding video when the same playing equipment plays different videos by alternately controlling the light transmission of the lens of each watching equipment, and the lens of the watching equipment is light-impermeable to not receive the non-corresponding video content when the video which is not corresponding to the watching equipment is played.
It should be appreciated that video content that is desired to be viewed is received by controlling the light transmission of the lenses on the viewing device, bypassing video content that is not desired to be viewed.
Taking the first viewing device GA and the second viewing device GB as an example for explanation, when the first video a is played, the lenses of the first viewing device GA are transparent, and the lenses of the second viewing device GB are opaque, and when the second video B is played, the lenses of the second viewing device GB are transparent, and the lenses of the first viewing device GA are opaque, as detailed in the following table.
TABLE 1
Video content played Light transmittance of GA lens Light transmittance of GB lens
A1 Light transmission Light-proof
B1 Light-proof Light transmission
A2 Light transmission Light-proof
B2 Light-proof Light transmission
A3 Light transmission Light-proof
B3 Light-proof Light transmission
An Light transmission Light-proof
Bn Light-proof Light transmission
It can be seen that the light transmittances of the lens of the viewing device GA and the lens of the GB can adopt multiple control methods, for example, the control signal can be sent to each viewing device through the same playback device to control the light transmittances of the respective lenses, for example, the control signal is sent to the first wearable device to control the opening time and the opening duration of the light transmittance of the lens of the first wearable device when the same playback device plays the first video, and so on to other wearable devices. The light transmittance of the lens of each viewing device can be periodically set by each viewing device after the light transmittance of the lens of each viewing device is calibrated according to the time rule that the same playing device alternately plays different videos.
It should be noted that, the video content played by the same playing device in different time periods may be at least one frame, or may be a frame group composed of a plurality of frames, so as to ensure that the viewer views a smooth picture.
In some embodiments, in a video playing method for a viewing device provided by an embodiment of the present specification, step 10: at least respectively controlling a first watching device to correspondingly receive a first video and a second watching device to correspondingly receive a second video, specifically comprising:
and at least respectively controlling a first viewing device to periodically correspondingly receive the first video and a second viewing device to periodically correspondingly receive the second video.
As can be seen from the above analysis, on the premise that the time for the same playing device to alternately play each video content is periodically regular, each viewing device may be controlled to periodically receive the corresponding video, for example, the time T1 for the same playing device to play the first video content, the time T2 for the second video to play the third video to T3, and then the time T1, … … for the first video to alternately play, so that the first video is alternately played after each interval T1+ T2+ T3, the playing time T1 is the same, the time intervals for the other videos to alternately play are the same, and only the playing times are different, and if T1= T2= T3, the playing times are also the same.

Before the same playing device alternately plays at least a first video and a second video, the at least first video and the second video need to be alternately sequenced according to respective fusion units to form a fusion video, the fusion units can be at least one frame or a frame group consisting of a plurality of frames, and as long as a viewer can watch a smooth picture.
The fusion video can be seen to fuse a plurality of videos together for playing through the alternate sequencing of the respective fusion units of the videos, so that a plurality of different videos are played in the same time period by using the same playing device, different watching devices receive the fusion units of the corresponding videos in the fusion video, and audiences receive the fusion units in the corresponding videos at different time points on the same watching device in sequence to see continuous pictures, thereby finishing the watching of the videos in the time period.
Furthermore, the frame rate of the fused video is the sum of at least the frame rate of the first video and the frame rate of the second video, so that the watching effect of the continuous video formed by all the fusion units watched by the audience after the frame rate of the fused video is adjusted is close to that of the video before the fusion, and the watching experience of the audience is improved.
Referring to fig. 2, in some embodiments, in a video playing method for a viewing device provided by an embodiment of the present specification, step 20: at least respectively controlling a first watching device to display a first video and a second watching device to display a second video, specifically comprising:
step 200: and the fusion unit is used for controlling at least the first viewing equipment to display the first video and the second viewing equipment to display the second video.
When the same playing device plays the fused video, when the playing device plays the fused unit of the first video, the first watching device receives and displays the fused unit of the first video, so that different audiences who use different watching devices can watch the favorite videos of the audiences, and particularly, the fused unit of some limit levels or violent lenses can be fused with the fused unit of some interesting child animations and then can face the groups of different audiences such as adults and children.
Referring to fig. 3, a video playing method for a viewing device provided in an embodiment of the present disclosure may be implemented by a video playing apparatus 10 for a viewing device, which is disposed at a receiving end, and includes:

For the video playing apparatus provided in the embodiments of the present specification, the receiving module 100 and the display module 110 may be the same component in each viewing device, such as a lens, and the corresponding video is displayed in real time when being received.
By adopting the scheme provided by the embodiment of the specification, a plurality of people can watch different television programs on the same television at the same time, and the premise is that the television or the set top box can play a fused video formed by a plurality of channels, for example, grandpa can watch war resistant history dramas that the grandpa likes, mom can watch soap dramas that the grandpa likes, children can watch cartoon that the grandpa likes, and the time for playing the television is saved.
For movie and television works with low noon-night or sitting rate, the same showing room of the cinema can play a plurality of movie works simultaneously, so that the field and the playing time of the cinema can be effectively saved.
In addition, for some films, children are not suitable for being watched by children, the video parts which are not suitable for children and the video contents of the programs of the children can be formed into a fused video, so that adults and the children can watch different pictures by using different watching devices.
In the technical solution of this specification, at least a first video and a second video are alternately played on the same playing device, and correspondingly, at least a first watching device is controlled to correspondingly receive the first video on the receiving side, and after a second watching device correspondingly receives the second video, the first video is correspondingly displayed on the first watching device, the second video is displayed on the second watching device, and a third video is displayed on the third watching device, … …, etc. Different viewers using different viewing devices can view videos meeting their needs, and videos which do not need to be viewed cannot be displayed on the viewing devices used by viewers who are not suitable for or interested in the videos. The same playing device can play different videos simultaneously, so that the working time of the playing device is reduced while the differentiation requirements of different groups are met, the video watching time of audience groups can be reduced particularly for movie theaters, and the time cost and the space cost are saved.

In this embodiment, the same playing device mentioned in this specification alternately plays different contents in at least a first video and a second video, the first viewing device receives the first video when playing the first video, the second viewing device receives the second video when playing the second video, … …, the nth viewing device receives the nth video when playing the nth video, and then the first viewing device receives the first video when playing the first video, such that the alternation is cyclic and may be regular or irregular, in order to ensure that different viewers using the respective viewing devices can view smooth videos, the time for playing the respective videos by the same playing device each time is short, and the time is short enough for the viewers not to perceive the videos.
In some embodiments, the video playing method provided in this specification embodiment uses the same playing device to alternately play at least a first video and a second video, and specifically includes:
and controlling the same playing device to periodically and alternately play at least a first video and a second video.
The time for playing each video content alternately by the same playing device can have a periodic rule, and each watching device can be controlled to receive the corresponding video periodically, so that the rhythm of video receiving of the watching device can be controlled well.
For example, the time T1 when the same playing device plays the first video content, the time T2 when the second video content is played, the time T3 when the third video content is played, and then the time T1 and … … when the first video content is played alternately, so that the first video content is played alternately after each interval T1+ T2+ T3, the playing time T1 is played, the time intervals when other videos are played alternately are the same, but the playing times are different, and if T1= T2= T3, the playing times are also the same.
Referring to fig. 5, in some embodiments, step 10': before the same playing device is used to alternately play at least a first video and a second video, the video playing method for a viewing device provided in the embodiment of the present specification further includes:
step 30: and alternately sequencing at least the first video and the second video according to the respective fusion units to form a fusion video.
Before the same playing device alternately plays at least a first video and a second video, the at least first video and the second video need to be alternately sequenced according to respective fusion units to form a fusion video, wherein the fusion units can be at least 1 frame or a frame group consisting of a plurality of frames, so that a viewer can watch a smooth picture.
The fusion video can be seen to fuse a plurality of videos together for playing through the alternate sequencing of the respective fusion units of the videos, so that a plurality of different videos are played in the same time period by using the same playing device, different watching devices receive the fusion units of the corresponding videos in the fusion video, and audiences receive the fusion units in the corresponding videos at different time points on the same watching device in sequence to see continuous pictures, thereby finishing the watching of the videos in the time period.
The following illustrates the process of forming a fused video:
the invention respectively processes the video part and the audio part of each video, wherein the video part is processed as follows:
the first video a is exemplified to be composed of fusion units a1, a2, A3, a4, a5, … …, An;
the second video B is composed of fusion units B1, B2, B3, B4, B5, … … and Bn;
the fusion units of the first video A and the second video B are alternately ordered to form a fusion video C, which is:
A1B1A2B2A3B3A4B4A5B5……AnBn；
it can be seen that the video lengths of the first video a and the second video B may be different, and in the case that the frame numbers are different, the fusion processing may not be required for the partial videos, as follows:
assuming that the second video B has 3 frames, the fused video obtained after the fusion process of the first video a and the second video B is A1B1A2B2A3B3A4 A5a5 … … An-1 An.
It should be noted that different videos may be fused at any position, such as some video works where portions of videos unsuitable for children are inserted.
Furthermore, the frame rate of the fused video is the sum of at least the frame rate of the first video and the frame rate of the second video, so that the watching effect of the continuous video formed by all the fusion units watched by the audience after the frame rate of the fused video is adjusted is close to that of the video before the fusion, and the watching experience of the audience is improved.
It can be seen that the frame rate of the fused video after the fusion processing is increased, for example, the frame rate of the first video a is 60 frames/second, and the frame rate of the second video B is also 60 frames/second, so that the frame rate of playing the fused video is 120 frames/second.
