[ detailed description ] embodiments
For purposes of promoting a clear understanding of the objects, aspects and advantages of the invention, reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements throughout. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1, fig. 1 is a flow chart illustrating a video delivery method of a mobile device according to an embodiment of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a video delivery method for a mobile device, which is applied to video delivery for a clustered mobile device including a plurality of mobile devices, and in particular, when a plurality of mobile devices in the clustered mobile device are traveling in a queue, the video delivery method for the mobile device includes the following steps S11 to S12.
S11, splitting the video to be played into a plurality of sub-videos with continuous time sequences according to the number of the mobile devices;
the number of the mobile devices included in the cluster mobile device is equal to the number of the sub-videos into which the video to be played is split, so that when each mobile device in the cluster mobile device performs queuing, the sub-videos played by each mobile device can form a continuous and complete video.
In one example, the mobile devices in the cluster of mobile devices may be spaced apart from each other and may be traveling in a horizontal queue or may be traveling in a vertical queue.
In another example, the mobiles in the cluster of mobiles can be spaced apart from each other and run in an "arc" queue, or in a "snake" queue.
It should be understood that what type of queuing operation is performed by each mobile device in the cluster mobile devices is determined according to an actual application scenario, and this is not limited by the embodiment of the present invention.
And S12, respectively transmitting the sub-videos to each mobile device based on the 5G communication network.
After the video to be played is split into a plurality of sub-videos with continuous time sequences according to the number of the mobile devices, the sub-videos are respectively transmitted to the mobile devices to be played based on the low delay characteristic of the 5G communication network, so that the mobile devices respectively play different sub-videos to form a continuous and complete video for passers to watch.
When each mobile device in the cluster mobile device is queued, the video delivery method for the mobile device provided by the embodiment of the invention enables passers-by to watch continuous and complete videos in a mode of sequentially watching the sub-videos played by each mobile device, and compared with the traditional video delivery method (each mobile device plays the same video), the video delivery method for the mobile device greatly improves the advertising effect and commercial value of the mobile device. In addition, compared with a 4G communication network, the 5G communication network has larger data capacity, and has sufficient bandwidth and low delay characteristics, and the embodiment of the invention further ensures the transmission stability by using the 5G communication network to transmit the sub-video.
Referring to fig. 2, fig. 2 is another schematic flow chart of a video delivery method of a mobile device according to an embodiment of the present invention.
As shown in fig. 2, as a possible implementation manner, each of the sub-videos has a corresponding timestamp, where the timestamp represents a time when the sub-video is transmitted to the mobile device, and in order to avoid collision of the sub-videos during transmission, the sub-videos are transmitted to the mobile devices through different transmission channels, the video delivery method of the mobile device may further include the following steps S21 to S26.
S21, splitting the video to be played into a plurality of sub-videos with continuous time sequences according to the number of the mobile devices;
here, step S21 is identical to step S11, and the detailed description of step S21 may refer to the description of step S11, which is not repeated herein.
It should be noted that, when the video to be played is split into a plurality of time-sequential sub-videos according to the number of mobile devices, each sub-video may have pixels with a specific aspect ratio, and each sub-video may move in four directions in a single row or a single column.
S22, respectively carrying out pre-delay processing on the sub-videos;
in one example, the separately pre-delaying the sub-video may include: the sub-videos are respectively pre-delayed to a first value, and the first value may be any one of 10ms to 200ms, for example, 50ms or 110 ms. It should be understood that the size of the first value is determined according to an actual application scenario, and the embodiment of the present invention does not limit this.
S23, carrying out delay adjustment on each transmission channel according to the delay parameter of each mobile device, wherein the delay parameter represents the delay required by transmitting the sub-video to the mobile device and is divided into a high delay parameter and a low delay parameter;
in one example, adjusting the delay of each transmission channel according to the delay parameter of each mobile device may include: performing delay reduction adjustment on the transmission channel corresponding to the high delay parameter; and carrying out delay rising adjustment on the transmission channel corresponding to the low delay parameter.
In practice, step S23 is to give a shorter delay adjustment to the transmission path with a longer delay time due to communication, whereas a longer delay adjustment is given to the transmission path with a shorter delay time due to communication.
S24, based on the 5G communication network, transmitting the sub-videos to each mobile device through different transmission channels respectively;
s25, respectively adjusting the playing parameters and the time delay of each sub-video according to the time stamp of each sub-video, the self parameters of each mobile device and the relative parameters between adjacent mobile devices, wherein the self parameters at least comprise the position and the speed of the mobile device, the relative parameters at least comprise the relative position and the relative speed between the adjacent mobile devices, and the playing parameters at least comprise the playing speed of the sub-video;
in practical application, adjacent mobile devices are in communication connection, and by acquiring relative parameters between the adjacent mobile devices and combining the timestamps of the sub-videos and the parameters of the mobile devices, the playing parameters and the time delay of the sub-videos are respectively adjusted, so that the mobile devices do not cause the audience to have a sense of difference when playing the sub-videos.
It should be understood that, in the process that each mobile device correspondingly plays each sub-video, step S25 may also be located, when the relative parameter between adjacent mobile devices changes suddenly, according to the relative parameter between adjacent mobile devices, and in combination with the timestamp of each sub-video and the own parameter of each mobile device, adjust the playing parameter and the delay of the sub-video, respectively, so as to ensure the fluency of each mobile device in playing the sub-video.
S26, when the 5G communication network fluctuates, respectively carrying out acceleration adjustment or deceleration adjustment on the playing speed of the sub-video according to the fluctuation condition of the 5G communication network;
when the 5G communication network fluctuates, the delay of each transmission channel cannot be adjusted, and frame skipping or blocking is not allowed, so that the playing speed of the sub-video needs to be adjusted in an accelerated manner or in a decelerated manner according to the fluctuation condition of the 5G communication network, so as to ensure the continuity of playing the sub-video between the mobile devices.
