Embodiment Construction
[0022] figure 1 It is a flowchart of a video transmission method provided by an embodiment of the present invention. The embodiment of the present invention aims at the inability to transmit a single high-resolution video with various service qualities in the prior art, resulting in a lack of flexibility in video transmission; in addition, the server converts the high-resolution video into a low-resolution video to improve The data processing capacity of the server is increased, the resource consumption of the server is increased, and a video transmission method is provided. The specific steps of the method are as follows:
[0023] Step S101, acquiring source video data;
[0024] The execution subject of the embodiment of the present invention is the video source end, and the video source end may specifically be a video capture device with a shooting function such as a camera or a video camera, or it may be connected to the video capture device and capable of obtaining video ...

The embodiment of the invention provides a video transmission method and a device. The method comprises the steps of acquiring source video data; dividing source video data into a first video stream and a second video stream; adopting a first bearer to send the first video stream to a server, adopting a second bearer to send the second video stream to the server and overlapping the first and second video streams as source video data by the server; and sending the first video stream or the second video stream to a terminal device. According to the embodiment of the invention, the source video data are divided into the first and second video streams, and the first and second video streams are sent to the server by adopting bearers different in service quality. Therefore, the video transmission flexibility is improved. In addition, the server only sends one of the first and second video streams to the terminal device, so that the conversion of a high-resolution video into a low-resolution video is not required. The data processing amount of the server is reduced and the resource consumption of the server is saved.
Description
technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a video transmission method and device. Background technique [0002] With the development of communication networks, multimedia data has become an indispensable source of information for users, and the transmission of multimedia data has become a research hotspot. [0003] In the prior art, the video source is that the sending device sends a single high-resolution video to the server through the Long Term Evolution (LTE for short) wireless communication system, and the server displays the high-resolution video, and at the same time the high-resolution Convert the video to low-resolution video, and send the low-resolution video to multiple terminal devices. [0004] Since the LTE wireless communication system supports various Quality of Service (QoS) transmissions, however, the prior art samples a single quality of service to transmit a single...
