Method for synchronously playing multi-viewing-angle pictures on digital television screen

Abstract

The invention provides a method for synchronously playing multi-viewing-angle pictures on a digital television screen. A program of digital television comprises video streams and corresponding audio streams which are from different cameras, wherein the video streams reflect different viewing angles. When receiving the program, a set-top box can select interesting video stream at a certain viewing angle and the corresponding audio stream to play in a full screen mode, or can select multiple video streams to play synchronously on the screen. When videos of video streams at multiple viewing angles are played at the same time, a mosaic mode can be selected for playing, or the video at one viewing angle is played as a main picture, and the videos at other viewing angles are played in a picture-in-picture mode, and the audio corresponding to the video of the main picture is played so that audiences can switch the video of the main picture anytime. The multi-viewing angle television is applied to sportscast, and audiences can freely select the videos from different cameras so as to meet personalized watching needs.

Description

[0001] technical field [0002] The invention relates to a display or television technology, in particular to a method for synchronously playing multi-view pictures on a digital television screen. Background technique [0003] In live broadcast programs such as sports events, there are many camera positions around the stadium, and they shoot from different angles at the same time. However, due to the limitation of TV transmission factors, only the videos shot by cameras from different angles can be played to the audience in turn. For this reason, the on-site director needs to select in real time from the video from each camera, so that the audience can only passively enjoy it according to the perspective selected by the director. The audience’s interest points are not necessarily the same as those of the director. If videos from different camera positions can be provided, the audience can choose videos from different perspectives of the scene to enjoy according to their own...

AI Technical Summary

Problems solved by technology

[0004] However, in analog TV technologies including cable TV, satellite TV, and terrestrial wireless TV, each channel can only transmit one video signal, and videos from multiple perspectives need to occupy multiple channels, and the current spectrum resources are very tight. Unsatisfactory

Simultaneous transmission of multiple channels requires the TV to have multiple tuners to watch at the same time, but now only a small number of TVs with picture-in-picture functions have dual tuners, and there is almost no possibility of realizing three or more pictures
