Abstract
A system for handling video content in a network, such as the Internet. Aspects of the system provide for accessing, distributing and maintaining digital video or other image content. Video content is acquired from content providers. Searching, and identification of desired video content is provided to users of the system by annotating video content with searchable text. The searchable text is accessed via a database where relational queries are used to identify desired content. Portions, or chapters, of the video can be linked to unique descriptions. This allows for indexing of video so that a viewer, or user, does not have to watch unwanted segments to get desired information. Access of the video by end users is facilitated by maintenance of multiple video servers that provide access to the content. Distribution of video broadcasts can be on-demand or in real-time. A preferred embodiment uses both satellite and on-location video distribution. Video information is pre-processed to compensate for artifacts, degradation and other undesirable effects that can be introduced into the video information due to compression. The speed of transmission to an end user from each of multiple se…
