A subtitle display method, storage medium and smart TV

Abstract

The invention discloses a caption display method, a storage medium and a smart TV. The method comprises the following steps: pre-creating a broadcast mechanism for monitoring a change of a playing signal of a TV program in real time and sending a broadcast; when an instruction of entering a live broadcast channel sent by a user is received, entering the live broadcast channel, and preparing to play the TV program; monitoring the state of the playing signal of the TV program in real time through the broadcast mechanism; and if it is monitored that the state of the playing signal of the TV program is normal, sending a caption starting broadcast through the broadcast mechanism so as to achieve the synchronous playing of the TV program and the captions. Meanwhile, by adoption of the caption display method disclosed by the invention, the creation and destruction of a Surface object are also completed in a Native layer of the system, the Surface object can flexibly display and close the captions according to the real-time change of the state of the playing signal without generating residual caption shadows, meanwhile the memory occupied by the Surface object can be better controlled, and intelligent controllability is really achieved.

Description

technical field [0001] The invention relates to the field of subtitle display on an intelligent television, in particular to a subtitle display method, a storage medium and an intelligent television. Background technique [0002] Currently, due to the simplistic way of processing subtitle logic on Android TV devices, the following problems usually occur during its use: [0003] 1) When the user needs to turn on the subtitle, the subtitle cannot be displayed normally, which affects the normal use of the user; [0004] 2) When the user closes the subtitle or exits the video playback state, the data of the last frame of the subtitle is not cleared and remains on the screen; [0005] 3) When the user repeatedly enters and exits the playback channel, the Surface is repeatedly created. After running for a period of time, Surface Flinger occupies too much memory, causing the system to freeze or memory overflow. [0006] Therefore, the prior art still needs to be improved and deve...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a subtitle display method, a storage medium, and a smart TV in view of the above-mentioned defects of the prior art, aiming at solving the problem that the logic processing method for subtitles on the existing TV equipment is too simple, and subtitles are prone to appear. However, it cannot be displayed normally, subtitles remain and the system freezes.
