Problems solved by technology

[0003] The video data is usually sent evenly at the sending end, keeping the video data within a certain frame rate range. However, due to network jitter or other factors, the video data cannot be transmitted uniformly during the video data transmission process, and the receiving end may not be transmitted part of the time. Receive a sufficient amount of video data, and may also receive excessive video data part of the time, which may cause video data to freeze or fast-forward during playback.

Embodiment Construction

[0052] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0053] The Internet of Vision is an important milestone in the development of the network. It is a real-time network that can realize real-time transmission of high-definition video, and push many Internet applications to high-definition video, high-definition face-to-face.

[0054] The Internet of View adopts real-time high-definition video exchange technology, which can provide required services on one network platform, such as high-definition video conferencing, video surveillance, intelligent monitoring and analysis, emergency command, digital broadcast TV, time-lapse TV, online teaching, live broadcast , VOD on demand, TV mail, personalized recording (PVR), intranet (self-managed) channel, intelligent video broadcast control, ...

Abstract

The embodiment of the invention provides a video playing method and device. A video-of-things server, a first video-of-things terminal and a second video-of-things terminal are deployed in video of things. The method comprises the following steps: the first video-of-things terminal receives video data, which is sent to a downlink communication link of the first video-of-things terminal by the video-of-things server and acquired by the second video-of-things terminal; the first video-of-things terminal calculates a transmission time loss value of the video data in a preset time period; and thefirst video-of-things terminal outputs the video data to the connected device according to the transmission time loss value for playing. In the case of network jittering, the speed of playing the video data is adjusted through the transmission time loss value so as to adaptively adjust the frame rate, achieve constant speed playing of the video data and slow down or avoid the phenomenon that the video data is stuck or speeded up while playing, thereby ensuring the watching effect.

Description

technical field [0001] The invention relates to the technical field of Internet of Things, in particular to a video playing method and a video playing device. Background technique [0002] With the rapid development of network technology, video communications such as video conferencing and video teaching are widely used in users' life, work, and study. [0003] The video data is usually sent evenly at the sending end, keeping the video data within a certain frame rate range. However, due to network jitter or other factors, the video data cannot be transmitted uniformly during the video data transmission process, and the receiving end may not be transmitted part of the time. Receiving a sufficient amount of video data may also receive an excessive amount of video data part of the time, which may cause video data to freeze or fast-forward during playback. Contents of the invention [0004] In view of the above problems, embodiments of the present invention are proposed to p...
