Abstract
An image display apparatus according to an embodiment of the present invention comprises: an IR emitter controller for recognizing a pair of 3D glasses connected to the image display apparatus; a video multiplexer for receiving a plurality of displayed video data using a plurality of pairs of 3D glasses, setting a frame rate for the plurality of video data to assign a frame period thereto, and multiplexing the plurality video data according to the frame period assigned at the set frame rate, when the plurality of pairs of 3D glasses is connected to the image data apparatus; and a display unit for frame-sequentially displaying the multiplexed video data.
Claims17
A method of processing a broadcast signal for displaying multi view in a display panel of a receiver, the method comprising:
- receiving the broadcast signal including a first service and a second service, wherein the first service includes first images for displaying video factors of the first service and the second service includes second images for displaying video factors of the second service;
- multiplexing multi view video data in which images of the first and second images are multiplexed alternately at a certain frequency in a time domain;
- encoding a control sequence for controlling open/close motion of each lens of first viewing eyeglasses for the first service and second viewing eyeglasses for the second service;
- transmitting the encoded control sequence to the first and second viewing eyeglasses;
- displaying the multi view using the multiplexed multi view video data;
- receiving a channel control signal from at least one of the first and second viewing eyeglasses;
- and
- displaying an On Screen Display (OSD) for channel controlling based on the received channel control signal.
A method of operating a viewing eyeglasses for watching multi view in a display panel, the method comprising:
- receiving a control sequence for controlling open/close motion of each lens of first viewing eyeglasses for a first service and second viewing eyeglasses for a second service, wherein the control sequence includes first information indicating a certain motion among the open/close motion for each lens of the first and second viewing eyeglasses;
- parsing the first information from the received control sequence;
- operating the open/close motion for each lens of the first viewing eyeglasses based on the first information;
- generating a channel control signal requesting an On Screen Display (OSD) to be displayed for channel controlling;
- and
- transmitting the channel control signal.
An apparatus for processing a broadcast signal for displaying multi view in a display panel, the apparatus comprising:
- a receiving unit configured to receive the broadcast signal including a first service and a second service, wherein the first service includes first images for displaying video factors of the first service and the second service includes second images for displaying video factors of the second service;
- a video multiplexer configured to multiplex multi view video data in which images of the first and second images are multiplexed alternately at a certain frequency in a time domain;
- an encoding unit configured to encode a control sequence for controlling open/close motion of each lens of first viewing eyeglasses for the first service and second viewing eyeglasses for the second service;
- an emitter configured to transmit the encoded control sequence to the first and second viewing eyeglasses;
- and
- a display unit configured to display the multi view using the multiplexed multi view video data,
- wherein the encoding unit is further configured to receive a channel control signal from at least one of the first and second viewing eyeglasses;
- and
- wherein the display unit is further configured to display an On Screen Display (OSD) for channel controlling based on the received channel control signal.
