However, since the TV program is being broadcast live, it is difficult to reproduce the picture dynamically. When the user finds the picture he wants to capture and takes out his mobile phone and other camera equipment to point it at the TV screen to take pictures, the picture he originally wanted to capture is often no longer available. Existence, it is difficult to capture the required pictures in real time, affecting the user's expression and effect
Moreover, if a camera is used to take pictures of the TV screen, even if the desired picture is captured, the shooting effect will be affected by reasons such as light and shaking, and the quality of the picture is often difficult to satisfy.

Embodiment 1
[0022] Such as figure 1 , the terminal 101 is a set-top box, and the user enters the screen capture state by using the remote control to invoke the screen capture application or double-clicking the hotkey of the remote control;
[0023] The video screenshot server 301 obtains the IP multicast stream address of the live broadcast signal of the TV program, receives the video stream, and sets up the time stamp of the video and the buffer zone of the corresponding image frame;
[0024] After the remote controller captures the screen, the set-top box submits the channel number, the user characteristic code and the time of the current screen capture to the screen capture interface server 201;
[0025] The screen capture interface server 201 responds to the screen capture request from the terminal 101, and obtains the channel number, user characteristic code and the time of the current screen capture;
[0026] The screen capture interface server 201 sets up a screen capture request ...
Embodiment 2
[0030] Such as figure 1 , using a mobile terminal as the terminal 101, the screenshot application requires registration of user information and binding set-top box device information when it is used for the first time, the user opens the screenshot application on the mobile terminal device, and sends a screenshot request;
[0031] After the mobile terminal captures the screen, submit the screen capture request parameters such as channel number, user characteristic code and current screen capture to the screen capture interface server 201;
[0032] The screen capture interface server 201 responds to the screen capture request from the mobile terminal, and obtains the channel number, user characteristic code and the time of the current screen capture;
[0033] The screen capture interface server 201 sets up a screen capture request queue, and establishes a mapping relationship for the timestamp and the corresponding image frame in the cache area of the mobile terminal and the ...

Abstract
The invention discloses a live television screen capturing system and a live television screen capturing method. A video screen capturing server of the live television screen capturing system obtains live signals, builds a timestamp of a video and a buffering zone corresponding to image frames and sends the corresponding image frames to a video screen capturing storage device according to a timestamp of a screen capturing request. A screen capturing interface server is used for receiving the screen capturing request of a terminal, obtains screen capturing request parameters in the screen capturing request, sets up the mapping relation among the terminal, the timestamp in the buffering zone of the video screen capturing server and the corresponding image frames according to the screen capturing request parameters, receives query and browse orders of the terminal, looks up the image frames on the video screen capturing storage device, transmits the image frames to the terminal, receives the issued order of the terminal and outwards issues the image frames which are screened and determined by the terminal. The video screen capturing storage device is used for storing the corresponding image frames according to the timestamp of the screen capturing request. According to the live television screen capturing method, clear scenes on a live television can be accurately captured and sent to a network in real time, the screen capturing operation is convenient and fast to carry out, and the screen capturing effect is good.
Description
technical field [0001] The invention relates to a live TV screen capture system and method for capturing live TV pictures. Background technique [0002] A basic attribute of TV is social networking. People's comments, discussions, exchanges and recommendations on programs make TV programs maintain a high degree of attention and ratings. Social TV services use this basic attribute to transplant people's social activities on TV programs in real life into a virtual network environment, so as to meet people's needs for commenting, discussing, communicating, and recommending programs. [0003] In order to meet the above-mentioned social needs, when users watch live TV programs, they often hope to intercept the pictures of the TV programs they are watching, and then share them on social networking sites such as Weibo through the network for the first time, and post comments through pictures with text, thereby Attract more people to comment, and it may even become a topic for dis...
