4. 4/37 Phase 1 Metadata Tools ToolDescription of toolDocument reference Classification schemes Sets of controlled terminology - These comprise simple- and multi-level, multi-axis labels that can be applied to a particular piece of content such as its genre or atmosphere TS 102 822-3-1 Content description metadata Information defining, describing and detailing content items - such as a programme's synopsis TS 102 822-3-1 CRIDA location independent identifier used to identify content or groups of content - Additionally it is used as the key to associate metadata with the content or group of content. TS 102 822-4 Instance description metadata Information that defines a particular occurrence of a multimedia element - such as a programme's location in a schedule TS 102 822-3-1 Segmentation metadata Information that describes elements of a whole piece of content in a way that allows it to be broken up - such as indexing stories in a news programme by subject thereby allowing only preferred stories to be viewed TS 102 822-3-1 Usage history metadata Information generated in a device that describes the actions by a consumer while interacting with that device. TS 102 822-3-1 User preference metadata Information that describes a user's profile - which has either been entered by themselves or generated by their device such as the consumer's demographic data. TS 102 822-3-1

5. 5/37 Phase 2 Metadata Tools ToolDescription of tool/functionalityDocument reference PackagingFramework for the association of disparate elements of content that are intended to be consumed as a whole. TS 102 822-3-3 TargetingInformation that allows the matching and delivery of relevant content based on a consumers profile. TS 102 822-3-3 InterstitialsFramework for the replacement of interstitials during playback depending on specific criteria. TS 102 822-3-4 E-Flyer/CouponWay of attaching pricing and discount information to content.TS 102 822-3-3 Terminal capabilities Description of the capabilities of an end user terminal that enables appropriate content to be captured and consumed. TS 102 822-3-3 New content typesInformation describing and detailing content types other than audio and video such as stills, text, games and applications. TS 102 822-3-3 Educational metadata Information describing and detailing content types that relate to educational content. TS 102 822-3-3 Data broadcastDescription of non-AV content.TS 102 822-3-3

6. 6/37 Phase 2 Service of DMB MAF ▣ DMB MAF intends to exploit all the Phase 2 metadata tools. ◈ But, some profiling and usage limitation may be required. ▣ Package Metadata ◈ In addition to audio-visual contents, various DMB contents can be acquired through DMB data channel or IP-based DMB services. ◈ Each can be consumed by itself or can be consumed together to provide more effective consumer experiences.  ‘Package’ ◈ Package metadata also describes synchronization (temporal) and spatial information between content to allow content to be consumed as the service provider intended. ◈ Using the synchronization information, multi-stream experience (e.g., multi-camera sports, or alternate audio and video documentaries) can be provided with content packaging. ▣ Coupons Metadata ◈ Provides the way to signal the existence of coupon, to explain the coupon, and to signal the method to retrieve the coupon. ◈ DMB MAF users may store the coupons with the associated contents and may retrieve and use them at any time.

7. 7/37 ▣ Targeting Metadata ◈ Provides metadata for automatic matching and delivering of relevant content to profiled consumers. Targeted substitution is based on user profile, usage history, etc. ◈ A DMB portal may uses user preferences and other attributes to selectively recommend or present a DMB MAF content to the targeted user. ◈ Also, an intelligent agent in the DMB MAF terminal may uses user preferences and other attributes to selectively acquire and record DMB contents. ▣ Interstitials Metadata ◈ Perform interstitial replacement at playback time based on a number of criteria. The criteria may be explicitly declared using the Interstitials metadata schema. ◈ With this Interstitials metadata, DMB MAF consumers may replace the interstitials in main AV with their preferable ones at storing time or at later time.
