Method and device for transmitting and receiving video

摘要

Disclosed is a method for transmitting a video, which is used for increasing video transmission and receiving quality. The method comprises: generating multiple layers of video streams; in accordance with an obtained first distortion value, obtaining a corresponding first antennae/video matching matrix; separately dispatching each layer of video streams to respective antennae in accordance with the first antennae/video matching matrix; and transmitting same in accordance with the dispatched video streams. Also disclosed are a device for achieving the method, and a method and device for receiving a video.

1. A method for video transmission, comprising:
generating multiple layers of video stream; according to an acquired first distortion value, acquiring a first antenna-video matching matrix corresponding to the first distortion value; scheduling each layer of the video stream to a corresponding antenna respectively according to the first antenna-video matching matrix; and performing video transmission according to scheduled video stream; wherein the acquiring the first antenna-video matching matrix corresponding to the first distortion value according to the acquired first distortion value comprises: (1)—randomly acquiring an antenna-video matching matrix as a second antenna-video matching matrix, acquiring a second average video distortion corresponding to the second antenna-video matching matrix, and setting the second average video distortion as a minimum video distortion; (2)—updating a temperature parameter; (3)—randomly selecting an antenna-video matching matrix as a third antenna-video matching matrix, and acquiring a third average video distortion corresponding to the third antenna-video matching matrix; (4)—judging whether the third average video distortion is smaller than the second average video distortion or not; (5)—setting the third average video distortion as a minimum video distortion when a result of the judging is positive; (6)—setting the third antenna-video matching matrix as a current antenna-video matching matrix; (7)—repeatedly executing (3) to (6) for M times; (8)—repeatedly executing (2) to (7) for N times; and (9)—determining the minimum video distortion obtained after (8) as the first distortion value, and acquiring the first antenna-video matching matrix corresponding to the first distortion value according to the determined first distortion value.
