System and method of displaying a video stream
First Claim
1. A method of displaying a video stream, the method comprising:
- detecting a channel change;
receiving a video stream corresponding to a changed channel, the received video stream to be displayed on a display device;
during a first time period, displaying a first version of the received video stream while recovering a second version of the received video stream, the first version of the received video stream having a lower video display quality than the second version of the received video stream, wherein the first time period begins no more than approximately 100 milliseconds after the detected channel change;
synchronizing the first version of the received video stream with the second version of the received video stream; and
switching from display of the first version of the received video stream to display of the second version of the received video stream during a second time period.

Abstract
The present disclosure is generally directed to a video stream processing system and to a 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.

6. A video stream processing system comprising:
-
a user interface to detect 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 video generation module responsive to the video detection module, the video generation module to communicate to the display device a first version of the received video stream while the video detection module recovers a second version of the received video stream, the first version of the received video stream having a lower video display quality than the second version of the received video stream, wherein the first version has a first resolution and the second version has a second resolution, wherein the second resolution is higher than the first resolution, the video generation module including synchronization logic to synchronize the first version of the received video stream with the second version of the received video stream; wherein the video generation module switches from communicating the first version of the received video stream to communicating the second version of the received video stream to the display device, and wherein the video generation module is to communicate to the display device the first version of the received video stream during a first time period, and wherein an audio signal with full resolution is provided to the display device during the first time period. - View Dependent Claims (7, 8)

9. A method of displaying a video stream, the method comprising:
-
receiving a video stream to be displayed on a display device; displaying a first portion of the video stream according to first display characteristics while recovering a second portion of the video stream, wherein the first display characteristics comprise a first resolution, and wherein the first portion of the video stream is displayed during a first time period and an audio signal is provided to the display device with full resolution during the first time period; switching from displaying the first portion of the video stream to displaying the second portion of the video stream, wherein the second portion of the video stream is displayed according to second display characteristics, wherein the second display characteristics comprise a second resolution, and the second resolution is higher than the first resolution; and displaying a blurred image on the display device while switching from displaying the first portion of the video stream to displaying the second portion of the video stream. - View Dependent Claims (10)
