25、contained representation of a single complete D-Cinema work, such as a motion picture, or a trailer, or an advertisement, etc. The Composition Playlist consists of an ordered sequence of Reel structures, each referencing a set of external Track Files, e.g. a sound or picture Track File, which are me

26、ant to be reproduced in parallel. Each Reel is analogous to a film reel and the Composition Playlist controls the order and timing of the playout of the Reels. 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this stand

33、list file and one or more track files which contain the actual essence. Specifications of track file formats are beyond the scope of this document. A Composition Playlist (CPL) is a document which specifies the manner in which track files are rendered. A CPL represents a composition as an ordered se

34、quence of Reels. Each Reel contains one or more Assets, which identify Track File segments to be reproduced in parallel. In other words, it specifies the assembly of track files both in parallel, e.g. sound with picture, and in sequence; e.g., Reel 2 after Reel 1. The Composition Playlist is typical

35、ly created under editorial control in the mastering environment and is then included in the D-Cinema package distributed to exhibition.

37、 Playlist The structures defined in this document are represented using the Extensible Markup Language (XML) XML 1.0, and specified using XML Schema XML Schema Part 1: Structures and XML Schema Part 2: Datatypes. This specification shall be associated with a unique XML namespace name Namespaces in X

38、ML. The namespace name shall be the string value “http:/www.smpte-ra.org/schemas/429- 7/2006/CPL“. This namespace name conveys both structural and semantic version information, and serves the purpose of a traditional version number field. Table 1 lists the XML namespace names used in this specificat

39、ion. Namespace names are represented as Uniform Resource Identifier (URI) values RFC 2396. These values shall be considered as simple strings, and applications should not attempt to resolve them as URLs.

Implementations shall

41、perform correctly with any XML compliant namespace prefix value that is associated with a URI from table 1. Datatypes from other schemas that are used in this document will be prefixed with the appropriate namespace qualifier (e.g., xs:dateTime). See XML Schema Part 2: Datatypes and XML-Signature Sy

42、ntax and Processing for further information about these types. The MIME type IETF RFC 2046 for a document containing a single Composition Playlist element as its root shall be “text/xml“. 4 Terminology The following terms are used to describe the features of this standard. Clip: A contiguous set of

43、Editable Units intended to be reproduced sequentially. Composition: A complete artistic or informational motion picture work, such as a feature, or a trailer, or an advertisement, etc. Editable Unit: The smallest temporal increment of access to Essence, e.g. a frame or a sample. Edit Rate: A number

44、of Editable Units to be reproduced during a temporal interval having a duration of exactly one (1.0) second. Because Edit Rate values are not always integer values and sometimes require many digits of precision, Edit Rate values are expressed as a rational number (the ratio of two integers). Essence

45、: The sound, picture and data resources that make up a Composition. Native Duration: The total number of Editable Units in a Track File. Native Start Point: The first Editable Unit of a Track File. All Track Files are viewed by a Composition Playlist as a sequence of Editable Units numbered from 0 (

46、zero). Consequently, the Editable Unit number of the Native Start Point of a Track File will always be 0 (zero). Native End Point: The last Editable Unit of a Track File. Playable Region: The set of Editable Units within a Track File that are intended to be reproduced as part of a Composition. A Tra

47、ck File may contain Editable Units before and/or after the Playable Region. Track File: A file containing a single Clip of simple Essence, such as sound, picture or subtitle essence. Sample Rate: The number of essence samples per second. Sample Rate values are expressed as a rational number (the rat

48、io of two integers). ISO 26429-7:2008(E) 6 ISO 2008 All rights reservedSMPTE 429-7-2006 Page 6 of 30 pages Frame Rate: The number of frames per second. Frame Rate values are expressed as a rational number (the ratio of two integers). Rational Number: A number value that is expressed as the ratio of

49、two integers. This provides for the definition of precise values that are not subject to the inaccuracies of floating point representation. 5 Synchronization The Composition Playlist defines an idealized playback timeline. As depicted in Figure 2, the timeline consists of a sequence of contiguous Reels. A Reel defines a temporal segment of the composition and consists of a set of single-essence Assets. start of Composition end of Composition Reel n Reel 1
