13、 Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). Significant changes since V1.2.3: The deliverable type of the present document has been changed from Technica
14、l Report (TR) to Technical Specification (TS). The tables in annexes A to D has been removed from the present document and are available only on the EBU web site (liltr,:l/%.inni.ebu.c3. The contents of the tables are maintained by EBU. NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to Co-
15、ordinate the drafting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is responsible for the standardization of radio and television receivers. The EBU is
16、a professional association of broadcasting organizations whose work includes the Co-ordination of its members activities in the technical, legal, programme-making and programme-exchange domains.

18、ervice Data Packet (extension data packet of type 8/30 format i), and the Country and Network Identification (CNI) fields of the Programme Delivery Control (PDC) data packets (extension data packets X/26 and 8/30 format 2). The present document also contains identification codes related to Video Pro
19、gramme System (VPS) CNI, which apply to German, Austrian and Swiss TV programme providers. Services like Teletext, PDC or VPS that contain Network Identification data in their formats may be used (besides their primary purpose) also as a reference for a source display or for Automatic Tuning Systems
20、 (ATS). The CNI codes are also used in Electronic Programme Guide transmissions. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

28、rogramme Type Television Video Programme System 4 List of codes The values of Network Identification codes of either type which have been so-far allocated and registered with the EBU, or identified from off-air reception, are given in annex A. 4.1 Teletext 16-bit Network Identification (NI) codes Th
29、ese 16-bit codes are uniquely designated for use by a single broadcast network, by definition, within the entire world. They are found in the teletext transmission in the so-called Broadcast Service Data Packet 30, Magazine 8, format 1, as defiied in EN 300 706 2. The 16 bits occupy bytes 13 and 14
30、of the packet. In this register the 16-bit codes are represented for convenience as 4-digit hexadecimal numbers. The number is read from left to right, the first transmitted bit being the Most Significant Bit (MSB) of the left-most hexadecimal number. Thus, for example, the code value AAE4 would be
31、transmitted in the order 1010 1010 11 10 0100. (This does not comply with other fields of packet 8/30 format 1). In default of a unique 16-bit code having been allocated to a particular network, the network operator should transmit the value 0000. 4.2 PDC Network Identification (NI) codes Programme
32、Delivery Control (PDC) services provide Network Identification codes in the Country and Network Identification (CNI) parameter. Two versions of this are hidden from display in Teletext programme guide pages or extension data packet type 26s, and in programme labels of extension data packet type 8/30
33、 format 2 or Video Programming System (VPS). These NI codes are uniquely designated for use by a single broadcast network or programme provider within a particular country (which is itself distinguished by a unique ITU country code), and it was generally left to the country to administer its own cod
34、e allocations. ETSI 7 ETSI TS 101 231 V1.3.1 (2002-12) Byte13 bit In earlier versions of this Register published by the EBU, the 1 1-bit coding used in extension packet 26 (Source Definition data group -4 bits in Data Word A plus 7 bits in Data Word B) was in all cases a direct subset of the 16-bit
35、coding used in extension data packet 8/30 format 2. With the growth of satellite and other cross-border transmission, it has become increasingly possible to receive broadcasts from geographically widely-separated countries which may have been allocated arbitrarily identical 1 1-bit PDC codes. The Re
36、gister was therefore rationalized in a way compatible with all existing consumer products to avoid the ambiguity that duplicated codes could cause. Users should therefore note the separation in the table of the PDC CNI codes into two columns representing the extension data packet 8/30 format 2 and e
37、xtension data packet 26 versions. NOTE: The relationship between the PDC NI codes and that of the Broadcast Service Data Packet (8/30 format i), is entirely arbitrary. For the detailed bit coding of the PDC CNI codes see EN 300 231 i, clauses 7.3.2.3 and 8.2.1, which are reproduced below for conveni
38、ence.

40、rogramme sources. Extract 2 of EN 300 231 i from clause 8.2.1 8.2.1 Transport via Teletext (ITU-R system B) This transport method is able to carry the parameters CNI, PIL, PCS, LCI and PTY. A 20-character version of PTL is also provided. The transport of the recording-control commands is carried out
41、 by means of the broadcast service data packets 8/30 format 2. As illustrated in table 1, this packet includes the prefix (5 bytes), the designation code (1 byte) and the initial Teletext page (6 bytes). The next 13 bytes, numbered 13 to 25, are each (8,4) Hamming coded using the method defiied for
42、system B Teletext. The four message bits of byte 13 are used as follows: The message bits of bytes 14 to 25 are used as follows; the arrangement is similar to the label coding method used in the dedicated television line transport method. ETSI 8 ETSI TS 101 231 V1.3.1 (2002-12) The remainder of the
43、packet (bytes 26 to 45) contains a 20-character version of PTL for display as a status message. 4.3 Ap p I i cation Type Application Type codes appear in the Bundle Information Structure of a data broadcasting service using the Page Format-Clear protocol. This is fully defined in clause 4 of 4. They
44、 enable a receiver to identi the applications present in the data stream. The codes allocated are shown in annex C. 4.4 Ap pl i cat ion I dent if er &plication Identifier codes appear in an IDL-format B. Such Teletext packets are fully defined in clause 6 of 4. The Application Identifier enables a r
45、eceiver to acceptkeject the applications present in a given data channel by filtering at the transport layer. The codes allocated are shown in annex D. 5 Coding examples Packet W26 Source Definition data group Consider the X/26 code 32 07. EN 300 231 i clause 7.3.2.3: c) (see clause 4) decrees that
46、the X/26 Source Definition comprises two data words, A and B consisting of 6 bits and 7 bits respectively. Thus the above series of bits would be represented in binary as 11 O010 I O00 O1 11 (the two MSBs of Data Word A are always set to 1 in this Mode). For transmission, the Data Words A and B are
47、placed Least Significant Bit (LSB) first, and interleaved with the parity bits (Px) appropriate to Hamming (24,lS). The resulting 24 bit Data Group becomes: ETSI 9 ETSI TS 101 231 V1.3.1 (2002-12) Packet 8/30 format 2 Consider a packet 8/30 format 2 code with C = 24 and NI = C7. This is equivalent t
48、o the following sequence of 16 bits: O010 O100 1100 0111. From table 2, the transmission order of these CNI bits (ignoring the Hamming protection bits) is as follows: Equivalent Bit allocation for VPS: I reserved I This order of transmission is necessary to align precisely with the bit ordering of V
