Problems solved by technology

[0002] The satellite channel refers to the communication path between the earth station and the communication satellite. The satellite channel can transmit video data packets through the satellite channel. Because the satellite channel has problems such as limited power, large interference, and low signal-to-noise ratio, it is difficult to transmit video data. There may be a problem of packet lo

Embodiment Construction

[0023] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] At present, the satellite channel refers to the communication path satellite channel between the earth station and the communication satellite. The satellite communication channel is the integration of satellite channel and mobile communication channel. The transmission characteristics of satellite communication channels are that the available frequency band is very wide and the bandwidth requirements are low. At the same time, other transmission characteristics of satellite channels that are close to shortcomings...

Abstract

The invention provides a video processing method and device and electronic equipment, and the method comprises the steps: setting a sequence identifier for each obtained first video data packet according to a time axis sequence; processing each first video data packet to obtain a plurality of second video data packets of which the occupied storage spaces meet a preset threshold range; encoding the plurality of second video data packets to obtain a plurality of third video data packets; and sending the plurality of third video data packets to a receiving device by adopting a satellite channel, and decoding and splicing the plurality of third video data packets according to the plurality of sequence identifiers through the receiving device to obtain a video splicing result. According to the mode, each first video data packet can be processed, so that the second storage space occupied by the second video data packet obtained after processing is within the preset threshold range, and the second video data packet meeting the preset threshold range is coded and transmitted; the method and the device can improve the packet loss resistance of video data packets transmitted by a satellite channel, and shorten the delay time at the same time.

Description

technical field [0001] The invention relates to the technical field of satellite channel transmission, in particular to a video processing method, device and electronic equipment. Background technique [0002] The satellite channel refers to the communication path between the earth station and the communication satellite. The satellite channel can transmit video data packets through the satellite channel. Because the satellite channel has problems such as limited power, large interference, and low signal-to-noise ratio, it is difficult to transmit video data. There may be a problem of packet loss during the packet process. In related technologies, the previous video frame is usually used to replace the current lost video frame, so as to hide the transmission error of the video frame. However, this method may have the problem that the image cannot be restored. You can choose to retransmit the entire lost video frame. This method has poor anti-packet loss performance and long ...
