6、ion. Headquartered and incorporated in the United States of America, SMPTE has members in over 80 countries on six continents. SMPTEs Engineering Documents, including Standards, Recommended Practices and Engineering Guidelines, are prepared by SMPTEs Technology Committees. Participation in these Com
7、mittees is open to all with a bona fide interest in their work. SMPTE cooperates closely with other standards-developing organizations, including ISO, IEC and ITU. SMPTE Engineering Documents are drafted in accordance with the rules given in Part XIII of its Administrative Practices. This SMPTE Engi
8、neering Document was prepared by Technology Committee F2. Intellectual Property At the time of publication no notice had been received by SMPTE claiming patent rights essential to the implementation of this Standard. However, attention is drawn to the possibility that some of the elements of this do
9、cument may be the subject of patent rights. SMPTE shall not be held responsible for identifying any or all such patent rights. SMPTE 271-2008 Page 3 of 12 pages 1 Scope 1.1 This standard specifies the position and dimensions of machine-readable identification numbers. These numbers are intended to b
10、e a machine-readable version of the latent image key number. This standard also specifies the encoding format to be used for these machine-readable numbers, as well as the area scanned and the spectral characteristics of the scanner. 1.2 This standard also specifies the position, dimensions, and con
11、tent of human-readable identification (key) numbers for use on 16-mm motion-picture films intended for original photography or intermediate printing which also include the machine-readable key number described in 1.1. These numbers normally will be exposed onto the film at the time of manufacture. 1
12、.3 This standard further specifies an area that may be used for optional manufacturer-specific film-type identification information. 1.4 This standard also specifies an area on the film which is not to be exposed by the film manufacturer, thus leaving it available for customer data recording. 2 Conf
13、ormance Notation Normative text is text that describes elements of the design that are indispensable or contains the conformance language keywords: “shall“, “should“, or “may“. Informative text is text that is potentially helpful to the user, but not indispensable, and can be removed, changed, or ad
14、ded editorially without affecting interoperability. Informative text does not contain any conformance keywords. All text in this document is, by default, normative, except: the Introduction, any section explicitly labeled as “Informative“ or individual paragraphs that start with “Note:” The keywords
15、 “shall“ and “shall not“ indicate requirements strictly to be followed in order to conform to the document and from which no deviation is permitted. The keywords, “should“ and “should not“ indicate that, among several possibilities, one is recommended as particularly suitable, without mentioning or
16、excluding others; or that a certain course of action is preferred but not necessarily required; or that (in the negative form) a certain possibility or course of action is deprecated but not prohibited. The keywords “may“ and “need not“ indicate courses of action permissible within the limits of the
17、 document. The keyword “reserved” indicates a provision that is not defined at this time, shall not be used, and may be defined in the future. The keyword “forbidden” indicates “reserved” and in addition indicates that the provision will never be defined in the future. A conformant implementation ac
18、cording to this document is one that includes all mandatory provisions (“shall“) and, if implemented, all recommended provisions (“should“) as described. A conformant implementation need not implement optional provisions (“may“) and need not implement them as described. 3 Normative References The fo
19、llowing standards contain provisions which, through reference in this text, constitute provisions of this standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this standard are encouraged to investigate the
20、 possibility of applying the most recent edition of the standards indicated below.

21、15283) SMPTE 271-2008 Page 4 of 12 pages 4 Definition key number: A number, sometimes referred to as an edge number or footage number, that is printed with ink or exposed onto the film at the time of manufacture. The numbers are placed at regular intervals, typically six inches for 16-mm film. For t
22、he purposes of this standard, the key numbers are latent-image exposed. 5 General Format 5.1 Format The general format of the latent-image identification information shall be as shown in Figure 1. 5.2 Use of the Other Edge No latent information shall be placed along the upper edge of the film, as sh
23、own in Figure 1. This area is reserved for data recording at the time of photography. 5.3 Film This identification information is intended to be printed onto film cut and perforated in accordance with SMPTE 109.
