Abstract

The invention provides a display system, a video playing terminal thereof, and a video watching terminal thereof. The system comprises the video playing terminal and the video watching terminal. The video playing terminal comprises a screen and a polaroid, wherein the polaroid is equipped with two polarizing directions which are alternatively arranged so that a light going through is polarized along a first direction and a second direction. The video playing terminal divides acquired four channel video signals into two groups, wherein each group comprises two channel video signals. In each group, even / odd column extraction or even / odd row extraction is carried out on video frames of each channel video signals, and video signals extracted from both channels are interlaced and recombined in rows or in columns. Two channel video signals that are interlaced and recombined are displayed on the screen with time sharing, while a simultaneous playing signal is sent. The video watching terminal comprises at least a pair of first liquid crystal shutter glasses, and opens or closes a liquid crystal layer according to the simultaneous playing signal. Thus, simultaneous playing of four channel video signals is realized, and application range of the system is broadened.

Description

technical field [0001] The invention belongs to the technical field of video playing, and in particular relates to a display system and a video playing terminal and a video viewing terminal thereof. Background technique [0002] The traditional TV display technology uses one TV to display one program picture, which cannot meet the needs of different viewers for different programs. In response to this problem, the prior art proposes two display systems: [0003] In an existing display system, digital technology is used to display two or more programs on the same display screen. Specifically, one or more compressed sub-pictures are simultaneously inserted on the main picture for normal viewing, so as to monitor other channels while enjoying the main picture. This kind of display system improves the user's viewing experience to a certain extent, but because the sub-picture will cover part of the main picture, it affects the normal viewing of the main picture, and the picture ...
