Method and apparatus for displaying video data

Abstract

Provided is a method and apparatus for displaying video data without a display delay. In the method, a code indicating an end of stream is appended so that the code is appended behind a last video stream included in a stream to be displayed when only a part of an input stream including one or more video streams is displayed. In addition, the last video stream is displayed which is appended with the code indicating an end of stream.

What is claimed is: 
     
         1 . A method of displaying video data, comprising:
 decoding a first stream; and   comparing reproduction time information of a picture to be displayed next with system time information, and, if a difference therebetween is below a predetermined value, controlling video data of the decoded first stream for displaying on a screen.   
     
     
         2 . The method of  claim 1 , wherein the system time information is determined as reproduction time information of a start video picture of a stream to be displayed. 
     
     
         3 . The method of  claim 2 , wherein, in the controlling of video data, reproduction time information of a picture currently being displayed is compared with the reproduction time information of the picture to be displayed next, and if a difference therebetween is below the predetermined value, the controlling is no longer carried out and is delayed for a period of time. 
     
     
         4 . An apparatus for displaying video data, comprising:
 a decoder which decodes a first stream;   a controller which compares reproduction time information of a picture to be displayed next with system time information, and, if a difference therebetween is below a predetermined value, controlling video data of the decoded first stream for displaying; and   a display which displays the video data decoded by the decoder on a screen under a control of the controller.   
     
     
         5 . The apparatus of  claim 4 , wherein the system time information is determined as reproduction time information of a start video picture. 
     
     
         6 . The apparatus of  claim 5 , wherein the controller compares reproduction time information of a picture currently being displayed with the reproduction time information of the picture to be displayed next, and, if a difference therebetween is below a predetermined value, does not operate and waits for a period of time.
