已有 2432 次阅读| 2012-11-6 09:24 |个人分类:DVB


 DVB标准是嵌入式多媒体开发经常要用到的标准,和重要参考,尤其是做mpeg2,和机顶盒以及欧洲市场的。本文试图首先分析DVB标准的基本相关性


1 DVB 应该包含哪些标准?

DVB 是独立于ISDN,ATSC,OpenCable之外的标准,主要是由以下:ETSI 标准组成的

1.1 ETSI EN 300 421: Framing Structure,Channel Coding and Modulation for 11/12 GHz Satellite Services V1.1.2 (1997-08)

--这个标准主要表示的是卫星编码系统

The present document describes the modulation and channel coding system (denoted the "System" for the purposes of
the present document) for satellite digital multi-programme Television (TV)/High Definition Television (HDTV)
services to be used for primary and secondary distribution in Fixed Satellite Service (FSS) and Broadcast Satellite
Service (BSS) bands.

1.2 ETSI EN 300 429: Framing Structure,Channel Coding and Modulation for Cable Systems V1.2.1 (1998-04)

--这个标准主要表示的是有线编码系统

1.3 ETSI EN 300 744: Framing Structure,Channel Coding and Modulation for Digital,Terrestrial Television V1.6.1 (2009-01)

--这个标准主要表示的是地面编码系统

1.4 ETSI EN 300 468: Specification for Service Information (SI) in DVB Systems V1.12.1 (2011-10)

The present document specifies the Service Information (SI) data which forms a part of DVB bitstreams, in order that
the user can be provided with information to assist in selection of services and/or events within the bitstream, and so
that the Integrated Receiver Decoder (IRD) can automatically configure itself for the selected service.

--这个是DVB STACK软件需要看到标准,包括了如何解码头端的信息给解码器

1.5  ETSI EN 300 472: Specification for Conveying ITU-R System B Teletext in DVB Bitstreams V1.3.1 (2003-05)

--这个是DVB teletext也是需要软件关注的

1.6 ETSI EN 300 743 Subtitling systems V1.3.1 (2006-11)

The present document specifies the method by which subtitles, logos and other graphical elements may be coded and
carried in DVB bitstreams. The system applies Colour Look-Up Tables (CLUTs) to define the colours of the graphical
elements. The transport of the coded graphical elements is based on the MPEG-2 system described in
ISO/IEC 13818-1 [1].

--这个是DVB subtitles也是需要软件关注的

1.6  ETSI EN 301 192:Specification for Data Broadcasting  - V1.4.1 (2004-06)

The present document is designed to be used in conjunction with EN 300 468 [2] and TR 101 211 [4]. The DVB System
provides a means of delivering MPEG-2 Transport Streams (TS) via a variety of transmission media. These TSs have
traditionally been oriented to containing MPEG-2 Video and Audio. Data broadcasting is seen as an important
extension of the MPEG-2 based DVB transmission standards. Examples for data broadcasting are the download of
software over satellite, cable or terrestrial links, the delivery of Internet services over broadcast channels (IP tunnelling),
interactive TV etc. Four different application areas with different requirements for the data transport have been
identified. For each application area a data broadcasting profile is specified in the present document. The following is a
short description of the application areas and the profiles.

--这个是数据广播,和 ETSI EN 300 468有很强的相关性

1.7 ETSI EN 301 775: Standard for Conveying VBI Data in DVB Bitstreams

The present document specifies a new VBI standard to be added to MPEG-2 and DVB to handle the transmission of
data intended to be transcoded into the VBI of MPEG-2 decoded video. The definitions given by the present document
are an extension of the format specified by EN 300 472 [2].

--VBI 是SI 的扩展之一

1.8 ETSI ES 200 800 V1.3.1 (2001-10)

The present document is the baseline specification for the provision of the interaction channel for CATV networks.

-- 互动有线电视CATV

1.9 ETS 300 801 August 1997

This European Telecommunication Standard (ETS) is the baseline specification for the provision of Return
Channel (RC) based on PSTN and ISDN to Digital Video Broadcasting (DVB) systems.

2.0 ETS 300 802 November 1997

This ETS covers the core Digital Video Broadcasting (DVB) requirements to enable interactive services
supporting broadcasting to the home with narrowband return channels (see annex A: Bibliography - "DVB
commercial requirements").

 


DVB 除了上述的基本标准外,还有implimentation and guider 标准给实际的一些假象例子和执行

1 TR 101 200 V1.1.1 (1997-09)

A guideline for the use of DVB specifications and standards

The present document gives an overview of the existing DVB documents. The present document should be regarded as a
"cookbook", listing all the ingredients for a DVB meal. It does not serve the purpose of giving a detailed description of
the contents of the DVB documents.

--这个是最需要了解到,文档的文档介绍,可惜版本有些老,而且更新少

2 ETSI TS 101 154 V1.9.1 (2009-09)

Specification for the use of Video and Audio Coding in Broadcasting Applications based on the MPEG-2 Transport Stream

--这个和coding相关

3 ETSI TR 101 190 V1.3.2 (2011-05)

Implementation guidelines for DVB terrestrial services;Transmission aspects

The present document gives the first guidelines for implementation of Digital Video Broadcasting Terrestrial (DVB-T)
transmitting networks.
Its primary intention is to be a guide to the transmission aspects, while receiver aspects have not been dealt with.

-- 这个实现是和头端有关,和本地和软件无关

4 TR 101 194 V1.1.1 (1997-06)

Guidelines for implementation and usage of the specification of network independent protocols for DVB interactive services

The basic requirement of an interaction channel is that the user be able to respond in some way to the Interactive Service
(IS). This response may take the form. of "voting" for a particular participant in a competitor show, "purchasing" goods
demonstrated/advertised in a shopping channel programme, etc. This would be achievable within a one-way (reverse
direction) narrow-band path.

-- 和互动频道有关的各种可能的实现

5 ETSI TR 101 202 V1.2.1 (2003-01)

Implementation guidelines for Data Broadcasting

The present document provides implementation guidelines for the use and implementation of the Digital Video
Broadcasting (DVB) data broadcast service in a DVB digital broadcast environment including satellite-, cable-,
MMDS- and terrestrial networks.

--数据广播的实现

6 ETSI TR 101 211 V1.9.1 (2009-06)

Guidelines on implementation and usage of Service Information (SI)

The present document provides implementation guidelines for the use and implementation of the DVB Service
Information (SI) coding in a DVB digital TV environment including satellite - cable - and terrestrial networks.
The guidelines are intended to be highly recommended rules for the usage of the DVB SI syntax specified in
EN 300 468 [i.1]. As such, they facilitate the efficient and reliable implementation of basic user-interaction functions in
Integrated Receiver-Decoders (IRD).

--软件参考最重要的实践标准SI


重要的独立标准

1 EN 50221   February 1997

Common Interface Specification for Conditional Access and other Digital Video Broadcasting Decoder Applications

-- CA系统的接口标准

2 ETR 289 October 1996

Support for use of scrambling and Conditional Access (CA) within digital broadcasting systems

This ETSI Technical Report (ETR) specifies the common DVB Conditional Access elements. It was
developed principally to provide support for a wide range of Conditional Access Systems (CASs) which
are based on ISO/IEC 13818-1 (MPEG-2) [1] and the DVB specifications. The ETR specifies those
aspects which are required for co-existence of multiple Conditional Access Systems in a single data
stream.

--CA

3 ETSI TR 101 288 V1.3.1 (2002-12)

The present document is intended as a companion document to the full specifications, EN 300 707 [1] and
EN 300 708 [2], covering the data format and transmission via Teletext of an Electronic Programme Guide (EPG).
It is primarily aimed at EPG/Teletext service providers and network operators with the intention that the specifications
are interpreted in a consistent way while recognizing that there are many options available to all the parties involved in
creating the total system.

-- EPG

4 ETSI TS 101 699 V1.1.1 (1999-11)

Extensions to the Common Interface Specification EBU

The present document presents a set of extensions to the command interface protocols of the common interface standardized in EN 50221 [5].
