System and method of displaying a video stream

Abstract

The present disclosure is generally directed to a video stream processing system and to a system and method of displaying a video stream. In a particular embodiment, the method includes receiving a video stream to be displayed on a display device. During a first time period, a low resolution version of the video stream is displayed while a full resolution version of the video stream is being recovered. The method further includes synchronizing the low resolution version of the video stream with the full resolution version of the video stream, and, during a second time period after the first time period, switching between display of the low resolution version of the video stream to display of the full resolution version of the video stream.

1 . A method of displaying a video stream, the method comprising:
 receiving a video stream to be displayed on a display device;   during a first time period, displaying a low resolution version of the video stream while recovering a full resolution version of the video stream;   synchronizing the low resolution version of the video stream with the full resolution version of the video stream; and   during a second time period after the first time period, switching from display of the low resolution version of the video stream to display of the full resolution version of the video stream.   
   
   
       2 . The method of  claim 1 , wherein the display device is a television. 
   
   
       3 . The method of  claim 1 , wherein the first period is less than three seconds. 
   
   
       4 . The method of  claim 1 , wherein a full resolution audio signal is provided to the display device during the first time period while displaying the low resolution version of the video stream. 
   
   
       5 . The method of  claim 1 , wherein a video quality of the full resolution version of the video stream is higher than a video quality of the low resolution version of the video stream. 
   
   
       6 . The method of  claim 1 , further comprising temporarily displaying a blurred image while switching from the low resolution version of the video stream to the full resolution version of the video stream. 
   
   
       7 . The method of  claim 1 , further comprising detecting a channel change request, wherein the first time period begins within one hundred milliseconds after detecting the channel change request. 
   
   
       8 . A method of displaying a video stream, the method comprising:
 detecting a channel change;   receiving a video stream to be displayed on a display device;   during a first time period, displaying a still image associated with the video stream while recovering the video stream; and   switching from display of the still image to display of the video stream as a full motion video display.   
   
   
       9 . The method of  claim 8 , wherein an audio signal is provided to the display device during the first time period. 
   
   
       10 . The method of  claim 8 , wherein the still image comprises a title screen. 
   
   
       11 . The method of  claim 8 , wherein the still image comprises a frame from the video stream. 
   
   
       12 . A video stream processing system comprising:
 a user interface responsive to a channel change request;   a video detection module responsive to the user interface, the video detection module to receive a video stream to be displayed on a display device; and   a display generation module responsive to the video detection module and coupled to the display device, the display generation module to:
 generate a still image associated with the video stream during a first predetermined time period; and 
 generate a full resolution version of the video stream to be displayed as a full motion video on the display device after a second predetermined time period. 
   
   
   
       13 . The video stream processing system of  claim 12 , wherein during the first predetermined time period the video detection module is recovering the full resolution version of the video stream. 
   
   
       14 . The video stream processing system of  claim 12 , wherein the first predetermined time period and the second predetermined time period are substantially the same. 
   
   
       15 . The video stream processing system of  claim 12 , wherein the system is further configured to provide a first audio signal during the first predetermined time period. 
   
   
       16 . The video stream processing system of  claim 15 , wherein the first audio signal is provided with full resolution. 
   
   
       17 . The video stream processing system of  claim 12 , wherein the still image comprises a frame from the video stream. 
   
   
       18 . The video stream processing system of  claim 12 , wherein the still image comprises a title screen. 
   
   
       19 . The video stream processing system of  claim 18 , wherein the title screen includes information regarding the video stream. 
   
   
       20 . The video stream processing system of  claim 19 , wherein the information includes one of a title of an episode, a title of a series, and a title of a movie to be displayed on the display device.
