AI Technical Summary

Benefits of technology

The disclosed method allows for quick and accurate navigation of streaming video without causing delays for the user. This is possible because the navigation is performed without buffering the video first, which is a common issue in prior art methods. The technical effect of this is improved user experience and efficient video navigation.

Problems solved by technology

Such latency is inherent in prior art navigation techniques since navigation operations are performed across the actual, unbuffered video stream.

Embodiment Construction

[0014]One embodiment of the present invention sets forth a computer-implemented method for real-time scrubbing of a streaming video. The method includes downloading a low-resolution version of the video and using the low-resolution version of the streaming video for display to facilitate navigation the video. Because the low-resolution version is fully downloaded before navigating the video takes place, any portion of the low-resolution version is available and any appropriate frame can be immediately displayed whenever a cursor is moved along a video timeline slider. Thus, during navigation along the video timeline slider, the low-resolution version of the video is displayed instead of the streaming, high-resolution version of the video. Once navigation ends, for example when a mouse button used to control the cursor is released, the display can snap back to the high-resolution streaming video and normal viewing of the video begins.

Abstract

A method for traversing a streaming video file includes receiving a representative streaming video file that includes less information than a higher-resolution streaming video file and spans the entire streaming video file. Based on navigation information associated with the representative streaming video file, a playback engine navigates to a different portion of the streaming video file. The navigation information may be based on input information received from a viewer of the streaming video file. One advantage of the disclosed method is that it enables fast and accurate navigation of a streaming video.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S)[0001]The present application claims priority to U.S. Provisional Patent Application No. 61 / 547,561, filed Oct. 14, 2011, the entire contents of which are incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates generally to video playback and, more specifically, to real-time scrubbing of on-line videos.[0004]2. Description of the Related Art[0005]Manually searching for a specific location in a digital video file by “scrubbing,” i.e., by moving a cursor along a timeline slider associated with the video, can be performed fairly conveniently with a downloaded video. This is because the current selected frame of the downloaded video can generally be accessed and displayed almost immediately after the cursor is positioned at any point on the timeline slider. This allows a viewer to quickly determine what portion of the video corresponds to the current cursor position and whethe...
