Embodiment Construction

[0034] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0035] The basic idea of ​​this application is: split and transmit the panoramic video data, and number the corresponding panoramic video and angle of view; at the display end, receive and decode the angle of view data in the background, and stitch and display the angle of view data in the foreground. Among them, the angle of view received and decoded in the background includes not only the angle of view displayed in the foreground, but also the angle of view adjacent to the angle of view displayed in the foreground along the moving direction of the estimated angle of view, so as to realize the early reception and decoding of the expected display data.

Abstract

The invention discloses a method for transmitting panoramic videos. The method comprises the following steps: splitting panoramic videos to be transmitted into viewing angle data corresponding to areas of different angles, and numbering the panoramic videos and the viewing angle data; allocating corresponding transport stream (TS) IDs and program numbers to the viewing angle data of the panoramic videos respectively, wherein different viewing angle data of the same panoramic video correspond to different TS IDs; and transmitting the viewing angle data of the panoramic videos on TSs identified by the TS IDs according to the TS IDs corresponding to the viewing angle data, and carrying corresponding panoramic video numbers and viewing angle numbers corresponding to the TS IDs and the program numbers of the viewing angle data in a PAT (Port Address Translation) table transmitted to a receiving end. Through adoption of the method, the transmission efficiency of the panoramic videos can be increased.

Description

technical field [0001] This application relates to video transmission and processing technology, and especially designs a panoramic video transmission and display method. Background technique [0002] At present, there are several implementation schemes for real-time transmission and display of panoramic video: [0003] 1. The entire video file is delivered through the server, resulting in extremely slow transmission speed, which seriously affects the viewing experience of users. [0004] 2. Use wavelet transform to compress and transmit data, corresponding to different playback windows, reconstruct the compressed data to generate video data of the current window. [0005] 3. The panorama data is collected in parallel based on the multi-channel acquisition equipment, and the data collected by the multi-channel acquisition equipment is transmitted through the network to form the panoramic data. On the playback side, a panoramic playback synchronization server is used to rea...
