Non-encoding device for 3D high-definition video

The utility model discloses a non-encoding device for a 3D high-definition video. The non-encoding device comprises a video input end, a video non-encoding processing assembly connected with the video input end and a video output end connected with the video non-encoding processing assembly. The video non-encoding processing assembly comprises a 3D video image separating module, an automatic identification subtitle machine and a non-encoding processor. The non-encoding processor is connected with a non-encoding display and a keyboard; the automatic identification subtitle machine is also connected with a character learning display and a remote controller; and the remote controller is provided with an area adjusting button for adjusting the size of a character learning area and position adjusting buttons for adjusting the upper position, the lower position, the left position and the right position of the character learning area. According to the utility model, characters in a video can be learnt by a machine, the labor is omitted, and the cost is reduced. Since the character display are in each video file is different, the character learning area in the automatic identification subtitle machine needs to be adjusted correspondingly, and in case that the remote controller is far away from the display, the character learning remote controller can rapidly adjust the position and the size of the character learning area so as to improve the working efficiency of a character learning process.
