4、rd This British Standard reproduces verbatim IEC 61119-4:1997 and implements it as the UK national standard. The UK participation in its preparation was entrusted by Technical Committee EPL/100, Audio, video and multimedia systems and equipment, to Subcommittee EPL/100/2, Recording, which has the re
5、sponsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK.
6、This standard is part of a series of British Standards implementing the IEC 1119 series, the other parts of which have mostly been published as ENs by the European Committee for Electrotechnical Standardization and implemented in the BS EN 61119 series. IEC 1119 includes the following Parts: Part 1:
7、 Dimensions and characteristics (EN 61119-1:1994); Part 2: DAT calibration tape (EN 61119-2:1994); Part 3: DAT tape properties (EN 61119-3:1994); Part 4: Character pack format; Part 5: DAT for professional use (EN 61119-5:1995); Part 6: Serial copy management (EN 61119-6:1994); Part 7: DAT logo. A l
8、ist of organizations represented on this subcommittee can be obtained on request to its secretary. From 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered as IEC 60027-1. For a period of time during the change over from one
9、numbering system to the other, publications may contain identifiers from both systems.

18、l Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fi
19、elds. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-gove
20、rnmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of
21、the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and
22、are published in the form of standards, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in
23、 their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declare
24、d to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical
25、committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical report of one of the following types: type 1, when the required support cannot be obtained for the publication of an International Standard, despite repeat
26、ed efforts; type 2, when the subject is still under technical development or where for any other reason there is the future but no immediate possibility of an agreement on an International Standard; type 3, when a technical committee has collected data of a different kind from that which is normally
27、 published as an International Standard, for example “state of the art”. Technical reports of types 1 and 2 are subject to review within three years of publication to decide whether they can be transformed into International Standards. Technical reports of type 3 do not necessarily have to be review
28、ed until the data they provide are considered to be no longer valid or useful. IEC 61119-4, which is a technical report of type 3, has been prepared by subcommittee 100B: Recording, of IEC technical committee 100: Audio, video and multimedia systems and equipment. The text of this technical report i
29、s based on the following documents: Full information on the voting for the approval of this technical report can be found in the report on voting indicated in the above table.

32、e This publication applies to the Pack information of the Subcode in the Sub data part of the DAT system. This publication describes how to use the newly defined Pack item=1001 (Character) and describes the expansion procedure of Pack item=0100 (TOC) out of many Packs which are defined for audio use
33、 (ID=0000) of the Sub ID. The purpose of this publication is to establish the writing and recording procedures, and to preserve the interchangeability of character information (called Characters hereafter) when used in the Subcode of DAT systems. The standard also includes the operation rules. 2 Ref
34、erences At the time of publication, the editions indicated were valid. All documents are subject to revision and parties to agreements based on this part of IEC 61119 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. Member
35、s of IEC and ISO maintain registers of currently valid International Standards. IEC 61119-1:1992, DAT cassette system Part 1: Dimensions and characteristics.

37、e character information Characters packs. This publication however does not cover the standardization of interface equipment, based on the following considerations: 3.1 The purpose of this publication is to define how the character information is to be recorded and reproduced, but not how images, gr
38、aphics or patterns are presented on interface equipment. 3.2 There are no restrictions with respect to output equipment. 3.3 There are no restrictions with respect to input equipment. 3.4 It is possible that the DAT main device and the interface equipment is separate. The definition of this interfac
39、e is beyond the scope of this publication and must be handled in the main DAT standard, when necessary. 3.5 In this publication, we prescribe the minimum control code needed to express the text images which are made up of the Character lines. If this control code cannot be followed perfectly due to
40、the restrictions of the output equipment, it is allowed when indicated. 4 Characters The amount of character information including each countrys special characters and signs, is enormous, even if graphic information is not taken into account. In this standard a format code (FMT) consisting of 8 bits
41、 is defined to deal with this diversity. However, the 8 bits code is not intended to define different sets of Character formats unless really necessary. Format FMT=00h, is the basic Characters set, defining figures and alphabets etc., to give a fundamental interchangeability. All DAT equipment which
42、 has the Characters function shall have the Characters playback function and it is recommended that it also has the Characters record function. Taking into account that this standard will be used worldwide, it is expected that in the main format FMT=00h will be used in order to avoid unnecessary Cha
43、racter sets.

44、ack is defined by Pack item=1001 and combinations of these packs are compiled to make text. 5.2 TOC time information TOC time information expresses the absolute time using manual TOC packs. 5.3 TOC character information TOC character information is text information made of TOC character pack data. T
45、he TOC character pack is recorded after the TOC time information. 5.4 TOC character pack For the TOC character pack the pack item = 0100. The TOC pack can record the time information of the program as TOC data as already defined. But in this standard, this TOC pack will be expanded: information, equ
46、ivalent to the text character pack, can be recorded, being the text of each program as a part of TOC. This TOC pack for text is called “TOC Character Pack”. 5.5 FMT FMT (format) indicates the kind of character set. For example, FMT=00H is a basic character set in accordance with the ASCII code and F
47、MT=02h defines the JIS Kanji character set. 5.6 Text Text means the sentence comprising combinations of characters using text character packs and TOC character packs. 5.7 Sort Sort defines the type of character information or attribution. For example, Sort=06h gives the artists name and 07h gives th
48、e composers name. 00h04h is intended for general use (excluding the above). 5.8 Real time recording Recorded at the same time as the main data. Character sequences which are to be recorded with the main data at the same time, and are to be displayed together with main data playback, must be recorded
49、 under REAL TIME RECORDING MODE. For example, this character information may correspond to explanations and lyrics of the music, which are displayed when the music is reproduced. This writing/reading must be synchronous to the main data recording/playback. 5.9 Concentrated recording In this mode the text is recorded concentratively at a certain position on the tape. The effective coverage of text recorded concentratively is defined by PNO in the Pack. This mode is used for text which does not require time indications, for example, a
