Technical Field
The invention relates to the field of television video playing, in particular to a playing resource management system.
Background
In a television system, there are a plurality of playing scenes of U disk video playing, online video playing, DTV video playing, ATV video playing, HDMI video playing and AV channel video playing. The same driving modules, such as a video decoding module, an image display module, an image quality optimization module and a deinterlacer module, are used for the playing scenes. These drive modules typically take a certain amount of time to start or stop operating. When the playing is started, the video decoding module needs 500ms for starting, the image display module needs 200ms for starting, the interlace module needs 200ms for starting, and the whole process needs 1.5 seconds from the starting to the playing of the image, in addition to others; it may also take 1 second for the drive module to exit play.
However, when the player starts and exits, the system cannot stop waiting for the completion of the start and the exit of the player, and in order to ensure the fluency of the system, the user can still switch to other interfaces fluently, even directly switch from the U-disk video playing to the DTV video playing through a shortcut key, or switch from the HDMI video playing to the online video playing. The user presses the remote controller key once in normal operation for only 100ms, and the key operations should be responded by the system.
Therefore, a contradiction occurs, and a user can quickly switch playing scenes, but the driving modules related to each playing cannot be started and exited quickly, and one playing can be started normally, and other players are required to wait for all playing resources (namely the driving modules) to be released, otherwise, a black screen, a flash back and even a dead halt easily occur.
Therefore, a playing resource management system capable of quickly responding and quickly switching players is urgently needed.
