NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to Co-ordinate the drafting of standar
14、ds 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 a professional association of br

The EBU has active members in about 60 countries in the European broadcasting area; its headquarters is in Geneva. European Broadcasting

Its aim is to establish the framework for the introduction of MPE
17、G-2 based digital television services. Now comprising over 200 organizations from more than 25 countries around the world, DVB fosters market-led systems, which meet the real needs, and economic circumstances, of the consumer electronics and the broadcast industry. The present document is part 1 of
18、a multi-part deliverable covering DVB System Software Update Specification, as identified below: Part 1: “Simple Profile“; Part 2: “Extended Profile“. I n t rod uct ion The present document defines agreements on which to base interoperability for system software update services and receivers. These
19、have been selected to minimize interdependencies between the parties involved. In particular: - It defines the signalling information that can be used to locate the transport stream containing the system software update service in a network via the NIT or BAT as appropriate. It defines the signallin
20、g information used to locate the system software update service in a transport stream (via the PMT). It defines the options for transmitting the actual system software update service in either a proprietary data transfer format, or a standardized 2-layer DVB data carousel (called standard update car
21、ousel from here on). - - ETSI 5 ETSI TS 102 006-1 V1.l.l (2001-12) - It defines an Update Notification Table (UNT) that can be used to enhance the system software update functionality in an upward compatible way. The table provides a standard mechanism for carrying additional information, e.g. updat
22、e scheduling information, extensive selection and targeting information, action notification, filtering descriptors. It defines a recommended format for exchanging the system software update data from receiver manufacturer to the network (or multiplex) operator for subsequent transmission. In case m
23、ultiple receiver manufacturers share the same standard update carousel this format allows such a multi-vendor carousel to be composed from individual manufacturers contributions in a simple way. - The present document has to be seen in context with ETR 162 3 and EN 300 468 4 because it describes add
24、itional descriptors used for system software update. ETSI 6 ETSI TS 102 006-1 V1.l.l (2001-12) 1 Scope The present document specifies a standard mechanism for signalling a software update service and the means to carry the data for such a software update service. Since receiver software is increasin
25、gly complex, such a software update service is required to guarantee the functionality of a receiver as well as to increase its functionality once deployed in the field. The present document builds on i, 3 and 4 for signalling and on 2 for data carriage. The present document does not define the mand
26、atory character of this protocol in a specific context, and it does not exclude the use of proprietary mechanisms for doing a software update. This allows a network to support horizontal market model receivers (e.g. MHP receivers). Equally it allows receivers requiring a software update service to b
27、e deployed in a network independent way. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

35、software update services: 1) Proprietary format streams. 2) Standard update carousel (potentially shared between manufacturers). 3) Update Notification Table based system software update services. The data-broadcast-id-descriptor identifies the system software update stream. System software update s
36、ervices can contain data of one or multiple receiver manufacturers. In case of (1) it is the responsibility of the receiver manufacturers potentially sharing the update service to identiSl their organizations stream, or the stream can be uniquely identified as being specific to a receiver manufactur
37、er through the dat a-bro adc ast-id-de scrip tor. In case of (2) the standard carousel contains the identification of the receiver manufacturer. In case of (3) selection information is passed in one or more specific UNTs optionally carrying multiple selection and targeting descriptors. This or these
38、 tables are referenced in the PMT. 5 Network (SI) Signalling The linkage descriptor with the linkage type of 0x09 (system software update service) conveys the location of the transport stream carrying a system software update service within a network or bouquet respectively. This descriptor shall be
39、 carried in the fiist loop of the NIT or in the first loop of a specifically identified BAT (called system software update BAT from here on). The system software update BAT is identified by the system software update bouquet-id OxFF00, and if the country-availability-descriptor is used, the country
40、code applicable should be 902 (all countries). This allows a receiver to quickly identiSl it. If the system software update BAT is carried in the transport stream of a network it shall be the same as in any other transport stream of that network carrying the system software update BAT. ETSI 8 ETSI T
41、S 102 006-1 V1.l.l (2001-12) NOTE: The preferred positioning of this descriptor is in the NIT. On large networks which operate in a partitioned way (typical for satellite) it may be prohibitive to carry this descriptor in the NIT (e.g. due to size constraints of the NIT), in which case carriage in t
42、he system software update BAT is appropriate. If OUIs (plus additional selector bytes) are listed in the linkage-descriptor the list of OUIs shall be complete in that it shall convey information about all software upgrades conveyed on the respective service. This allows a receiver to conclusively de
43、tect that it may not have to further explore a service. A specific OUI with value Ox00015A has been reserved by DVB. This OUI might be used for other purposes despite the System Software Update described in the present document. Within the scope of the present document it is used to signal that the
44、data-broadcast-id-descriptor does not signal any specific OUI. In that case further selection information shall be carried either in the standard data carousel or the Update Notification Table as referenced in the descriptor. If the DVB OUI is used only this single OUI shall be contained in the loop
45、 of the data-broadcast-id descriptor. There can be multiple descriptors in the NIT or system software update BAT to allow multiple system software update services to be identified. It is specifically not the intention to remove this descriptor from the NIT or BAT in case of temporary absence of the
46、service. For this purpose specific organization identification (OUI) shall not be removed from this descriptor in case of temporary absence of a system software update service for receivers of identified organization. 5.1 Linkage descriptor for systems software update Table 1: Syntax for the private
