Embodiment 1

[0035] refer to figure 1 , which shows a flow chart of a method for publishing program content to the Internet according to the present invention, and the method specifically includes:

[0036] Recording step S101: collect video and audio signals of the game, generate video and audio materials of a preset time period, and record the absolute start time and end time of each material at the same time;

[0037] Preferably, before the recording step S101, the method further includes:

[0038] Setting step S100: set the time period for generating video and audio material currently.

[0039] Before the start of the game, set the time period of the current video and audio material to be generated. In practical applications, the time period can be set according to the playback requirements of the game. For example, set: generate a complete piece of material every 10 minutes, Or generate a complete piece of material every 5 minutes, etc., by collecting video and audio signals of the ...

Embodiment 2

[0054] refer to figure 2 , which shows a system structure diagram of a real-time release of game shots of the present invention, the system specifically includes:

[0055] The recording module 201 is used to collect video and audio signals of the game, generate video and audio materials of a preset time period, and record the absolute start time and end time of each section of material;

[0056] The recording module 202 is used to record the absolute time of the key shots in the game in real time;

[0057] The editing module 203 is configured to obtain the entry point of the key shot in the current material according to the time difference between the recorded absolute time of the key shot and the absolute start time of the corresponding segment of material, and edit the key shot for playback.

[0058] Preferably, the clipping module 203 includes the following submodules:

[0059] The obtaining sub-module 2031 is used to obtain the entry point of the key shot in the current...

Abstract

The invention provides a method and system for realizing real-time publication of competition scenes. The method comprises the following steps of: generating audio-video materials in a preset time period by carrying out file fragmentation on the materials; meanwhile, recording absolute starting time and finishing time of each fragment of the materials, and recording the absolute time of a key scene in the competition in real time to obtain an enter-point of the key scene of the current material according to a time difference between the recorded absolute time of the key scene and the absolute starting time of a relative section of the materials, and clipping the key scene for playing back; therefore, the real-time extraction of the key scene of the competition is realized, and the requirement for fast playback is met.

Description

technical field [0001] The invention relates to the technical field of program broadcasting in the radio and television industry, in particular to a method and system for realizing real-time release of game shots. Background technique [0002] In the IBC system (International Broadcasting and Television Center) of large-scale sports events, there is generally an event sharing function for game materials. During the live broadcast of sports events, a real-time record system is generally used to record key information of the live content of the game that has just passed, such as the moment of shooting Wait, in order to broadcast and replay, it is required to collect the signal of the game field, and then complete the video and audio files according to the collected content, extract key frame pictures, and record event information for human retrieval. [0003] However, under normal circumstances, if the game is not over, the video and audio files of the collected game screen ca...
