Abstract

The invention discloses a live broadcast annotation method and device, a terminal and a live broadcast system. The live broadcast annotation method comprises the steps of acquiring first touch path information corresponding to a touch operation performed by a local user on a local touch screen; drawing a first annotation track corresponding to the touch operation according to the first touch path information, sending the first touch path information to a display terminal which establishes connection with the local terminal so as to enable the display terminal to draw a second annotation track displayed on the display terminal according to the first touch path information; and displaying the first annotation track to the local user through a screen. Through adopting the above technical scheme, the embodiment of the invention can perform annotation on the live broadcast content in the live broadcast process, so that users of the display terminal are enabled to be more targeted when watching the live broadcast, and the display effect of the live broadcast is improved.
