Abstract

Provided is a system for playback of ultra high resolution video using multiple displays. The system comprises multiple image decoders for decoding each of multiple image files to provide the decoded images to each of multiple displays; management server to provide multiple image files; and relay transmitter to receive the multiple image files from the management server and then distribute the multiple image files to corresponding multiple decoders, wherein the relay transmitter receives display delay time and decoding order for the image files from the management server, and broadcasts the relay time and decoding start order to the multiple image decoders, and each of multiple image decoders decodes corresponding image file in accordance with the decoding start order, respectively, and provides the decoded image to each of multiple displays after delay time.

Claims

1. A system for playback of ultra high resolution video using multiple displays, comprising multiple image decoders for decoding each of multiple image files to provide the decoded images to each of multiple displays;

management server to provide multiple image files; and

relay transmitter to receive the multiple image files from the management server and then distribute the multiple image files to corresponding multiple decoders, wherein the relay transmitter receives display delay time and decoding order for the image files from the management server, and broadcasts the relay time and decoding start order to the multiple image decoders, and each of multiple image decoders decodes corresponding image file in accordance with the decoding start order, respectively, and provides the decoded image to each of multiple displays after delay time.

2. The system for playback of ultra high resolution video using multiple displays according to claim 1, wherein the management server sets image decoders as destination which plays back each of image files, and transmit data of multiple image files to the relay transmitter, or transmits divided image files with the time range, frame, picture or data size simultaneously.

3. The system for playback of ultra high resolution video using multiple displays according to claim 1, wherein the image decoder estimates and provides to the management server the time between the decoding started and the decoded image output, and the management server determines the display delay time based upon the time lapse from the image decoders.

4. The system for playback of ultra high resolution video using multiple displays according to claim 1, wherein the multiple displays are arranged to form m×

n (m and n are integers >

1) rectangular matrix.

5. The system for playback of ultra high resolution video using multiple displays according to claim 1 according to claim 1, wherein multiple displays are arranged in random pattern.
