6.1.2. Terms
Pricing, content restrictions, and royalty information are bundled together to create a set of Terms. These terms represent the business agreements that accompany an offer and may be reused in more than one offer. The terms apply to all of the content included with the offer.
6.1.3. Category
A Category defines a set of category paths that are used for presentation in a VOD menu system.
6.1.4. ContentGroup
A ContentGroup is a combination of all of the related content (movies, previews, images, etc.) with its Title metadata. A Title is presumed to always be included and at least one form of content. Groupings of content may be reused by combining them with terms to create different offers. A ContentGroup may contain multiple types of content or multiple versions of the same content. For example, a content group could contain metadata for both the standard and HD version of the same movie, if the two are interchangeable and can be represented by the same set of terms in the referencing offer.
6.1.5. Title
The Title defines the descriptive metadata for a movie or set of movies (or programs). This may be information that is used for actual display on the user’s screen (e.g., Name of the movie, Actors), or may be used in the VOD system for classification or display constraints (e.g., Rating). Titles may be shared between different content groups, but only one title will be associated with a given content group.
6.1.6. ContentAsset
ContentAsset is the metadata asset that represents the actual content files distributed to the end system.
6.1.6.1. AudioVideo
ContentAsset This category of ContentAsset includes Movies, Previews, and Barkers. A Movie is the actual audio video content that’s being offered to the user and is subject to the terms referenced in the offer. A Preview is an audio video promotion for the same movie, but is assumed to not be subject to the price expressed in the terms unless otherwise agreed. Note that a Movie can actually be any type of audio video content where the terms apply
6.1.7. Advertisement
An Advertisement is a specialized form of a Title asset that includes a reference to the Ad-ID schema for expressing metadata specific to ads. An Advertisement may be used in place of a Title in the ContentGroup if the corresponding content is indeed an ad.
6.1.8. SignalGroup
A SignalGroup is a collection of SignalPoints and/or SignalRegions. Signals are points or regions, constrained by 2 points of interest, and are essentially identified time indexes related to a video asset. Signal metadata may contain additional information about how it was acquired from a corresponding in- band signal. Signal point positions within an asset may be based on a fixed time index and/or contain data to support association with an in-band signal.
6.1.9. PlacementOpportunityGroup
A PlacementOpportunityGroup is a collection of PlacementOpportunityPoints and PlacementOpportunityRegions along with an expression of various rules regarding the placement opportunity. The points and regions will typically correspond with Signal points and regions associated with the video content.
7.8. Extensibility
The base asset type defined in the Core namespace includes an Ext element, which allows any content (elements or attributes) from any namespace to be included. This makes it easy to extend or customize an asset in a predictable manner while enabling filters or transforms to be applied. Any consumer of XML documents following this specification can safely ignore contents of the Ext element unless they otherwise have an agreement with the XML document producer. There is no requirement by this specification that the contents of the Ext element be validated, regardless of whether a namespace is provided. ANSI SCTE 236-2017 pdf download
