Embodiment 1

[0047] Embodiment 1 of the present invention provides a live annotation method. The method can be executed by a live broadcast annotation device, wherein the device can be implemented by software and / or hardware, and generally can be integrated in a live broadcast terminal. figure 1 is a schematic flow chart of the live annotation method provided in Embodiment 1 of the present invention, as shown in figure 1 As shown, the method includes:

[0048] S101. Acquire first touch path information corresponding to a touch operation performed by a local user on a local touch screen.

[0049]In this embodiment, the trigger condition for obtaining the first touch path information can be set as required, for example, the first touch path information corresponding to the touch operation of the local user on the local touch screen can be obtained according to the set cycle, When it is detected that the touch source of the user's touch operation (such as the user's finger or stylus, etc.) ...

Embodiment 2

[0062] figure 2 It is a schematic flow chart of a live annotation method provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above embodiments. In this embodiment, "adjust the first annotation track on the local screen based on the change of the first display position of the annotation scene on the local screen." Two display positions" are optimized to: obtain the movement information of the local camera and the depth of field information of the annotated scene corresponding to the first annotation track displayed on the local screen; determine that the annotated scene is at the local end according to the movement information and the depth of field information The pixel offset value of the first display position in the screen; based on the pixel offset value and the second display position of the first annotation track in the local screen at the current moment, determine the position to which the first annotation track needs to ...

Embodiment 3

[0081] Embodiment 3 of the present invention provides a live annotation method. The method can be executed by a live broadcast annotation device, wherein the device can be implemented by software and / or hardware, and generally can be integrated in a display terminal. Figure 3A A schematic flow chart of the live broadcast annotation method provided by Embodiment 3 of the present invention, as shown in Figure 3A As shown, the method includes:

[0082] S301. Obtain the first touch path information sent by the live broadcast terminal that has established a connection with the current terminal and the pixel correspondence between the live broadcast terminal and the current terminal, wherein the pixel correspondence is the relationship between each first pixel in the screen of the live broadcast terminal and The corresponding relationship of each second pixel in the current front screen.

[0083] In this embodiment, the current end can establish a connection with the live broadc...

Abstract

Disclosed in the present invention are a live broadcast annotation method and apparatus, a terminal, and a live broadcast system. The live broadcast annotation method comprises acquiring first touch path information corresponding to a touch operation performed by a local terminal user on a touch screen of the local terminal; on the basis of the first touch path information, drawing a first annotation trajectory corresponding to the touch operation and sending the first touch path information to a display terminal connected to the local terminal, such that the display terminal draws a second annotation trajectory displayed on the display terminal on the basis of the first path information; and displaying the first annotation trajectory to the local terminal user by means of a screen. By means of the aforementioned technical solution, the embodiments of the present invention enable annotation to be implemented on live broadcast content during the live broadcast, so that the display terminal user is more targeted when watching a live broadcast, improving live broadcast viewing effects.

Description

technical field [0001] The present invention relates to the field of live broadcast technology, in particular to a method and device for annotating live broadcast, a terminal and a live broadcast system. Background technique [0002] In recent years, with the development of information processing technology, more and more live broadcast scenes have been applied to the fields of education and conferences. [0003] In an education or meeting scenario, the teacher or the speaker can demonstrate the experiment or equipment to other people in the classroom or meeting room through live broadcast in front of the classroom, in front of the meeting room or in other places. Collect camera data of electronic devices such as mobile phones or computers as live broadcast devices, and further encode the collected camera data (such as H.264 encoding) and send it to interactive smart tablets in classrooms or conference rooms, etc. Display equipment, so as to realize the live broadcast of th...
