Problems solved by technology

While random dragging or moving of the playhead may seem like an infinite flexibility to the end user, dragging to a point like this usually involves random guess work and the user is often required to watch for a short period of time in order to Determines whether to continue playback from here, or do another random drag operation to find another point in the media

Abstract

An advanced media preview unit includes a preview generation processor (300) that extracts a number of preview frames and generates a preview media file in a preview generation process (300). The preview frames are saved in a layered data structure. In addition, the preview frames may be scaled to a lower resolution so that the preview file formed by the preview frames is reduced in size. The preview media file is delivered to a user through a preview delivery process (302). For example, a delivery scheduling scheme delivers the preview frames at selected time points to minimize startup delay and playback jitter. At a user side, through a plug-in module, the advanced media preview unit performs a preview rendering process (304).

Description

[0001] cross reference [0002] This application claims priority from earlier applications of U.S. Provisional Application No. 61 / 300,64, entitled "System for Generating, Transmitting, and Displaying Mobile Previews for Online Media Services," filed February 2, 2010, and 2011 Priority to U.S. Nonprovisional Application No. 13 / 018,121, entitled "System and Method for Online Preview," filed January 31, the contents of both earlier applications are incorporated by reference in this text. technical field [0003] The present invention relates generally to a system and method for online media, and more particularly to a system and method for online media preview. Background technique [0004] In a typical media platform or delivery system, on-demand media, such as video, audio, and other types of multimedia, displays content through a media player that allows users to randomly seek to any point to continue video playback. Generally, there are two ways to consume media content: ...
