[0030] overview

[0031] exist figure 1 In the exemplary multimedia system 100 shown, a "MediaDescription" 102 is a token that provides at least two pieces of information about each multimedia "content item" in the multimedia system 100 . A content item may be a program or a segment of a program. Firstly, MediaDescription 102 provides a description of the content item, and secondly, provides acquisition information for obtaining the content item. The descriptive aspect of MediaDescription 102 can generally be immediately integrated into an electronic program guide (EPG) within multimedia system 100, while the obtainable aspect of MediaDescription 102 can generally be executed by a client device to easily obtain the content. MediaDescription 102 provides a common language for the components of the exemplary multimedia system 100 . It should be noted here that the "descriptive metadata" that MediaDescription 102 can convey or reference can be EPG data (including, for example,...

Abstract

The present invention provides a MediaDescription data structure that includes both descriptive metadata, such as EPG information, about a multimedia content item and instructions for acquiring the content item is assigned to each multimedia content item in a multimedia system. A MediaDescription data structure is transferable as a token for representing the content item. The acquisition information may also include information about presenting the content item in different view contexts, as well as information about relationships to other pieces of content, and information about how each different version of the content item is to be acquired and displayed (310). MediaDescription data structure tokens can be used to facilitate digital video recording (DVR) processes, Internet content rendering processes, multimedia search processes, search results aggregating processes, video-on-demand (VOD) processes, pay-per-view processes, and program guide rendering processes.

Description

technical field [0001] The invention described herein relates generally to multimedia systems and, more particularly, to the MediaDescription data structure for conveying descriptive content metadata and content acquisition data within a multimedia system. Background technique [0002] In multimedia systems, technology must be provided to represent the end user's content, to determine which services are available, and how to represent individual services when selecting services. In the early days of television, the list of available services was predetermined; there were 12 bands on which a TV signal could communicate, and customers could choose any of them. The metadata about the content delivered on the channel is actually transmitted "out of band" in the form of news listings or TV guide magazines. Similar settings are also used for wireless broadcasting. [0003] As television moved to digital transmission, content delivery technology became more complex, as multiple s...
