kSIST prES 202 184 V2.1.1:2010 is SIST’s publication of the MHEG-5 Broadcast Profile. It specifies a profile for enhanced interactive TV receivers based on MHEG-5, covering application behaviour, signalling, graphics, text, file systems, and receiver interaction with broadcast and broadband services. It is aimed at receiver implementers, application authors, service providers, and test teams that need a common broadcast-interactivity profile.
What does kSIST prES 202 184 V2.1.1:2010 specify?
kSIST prES 202 184 V2.1.1:2010 defines a complete MHEG-5 system for enhanced interactive TV in digital broadcasting. Unless otherwise stated, the functionality in the document is mandatory, so a conforming receiver is expected to implement the specified behaviour rather than treat it as optional.
The scope extends the existing profile for HD operation and connection to a broadband interaction channel. It also adds enhanced font rendering, support for interaction with PVRs and DVB-CI, broader character repertoire for languages including Chinese and Polish, and corrigenda from implementation of V 1.1.1.
The document is organized into clauses 1 to 17, followed by Annex A and Annex B.
| Annex | What it covers |
|---|---|
| Annex A | Informative examples and guidance on visual appearance, user navigation, channel selections within an information service, and use of video within an information service |
| Annex B | Normative allocation of codes for use with the present document |
What are the key requirements of kSIST prES 202 184 V2.1.1:2010?
kSIST prES 202 184 V2.1.1:2010 requires receivers to implement the MHEG-5 profile, manage application life cycles, present graphics and text consistently, and support both broadcast and IP-connected retrieval of content. The practical effect is that authored applications should launch, render, tune, and interact in a predictable way across compliant receivers.
Application control and signalling
Clause 8 defines the application model, including launching, terminating, auto-boot broadcast applications, application context, and keeping an application running across service tunes. Clause 9 then specifies the signalling used to find the auto-boot application and its initial object through PMT and ServiceGateway signalling packages.
- Receivers support application stacking with an application identifier stack that can hold references to five applications.
- Receivers follow the service-level and network-level boot information rules so the correct application starts after tuning or service changes.
- The document distinguishes broadcast applications, CI introduced applications, and the Interaction Channel, so implementers know which file system and launch path to use.
In practice, this is what keeps an interactive service from disappearing or restarting incorrectly when the viewer changes channel or when the application is started automatically.
Engine profile, input, and resident programs
Clause 11 is the core engine profile. It ties the receiver to ISO/IEC 13522-5 and then defines the classes, features, engine events, and resident programs that a compliant engine shall support.
- The engine class set and feature set define the common MHEG-5 behaviour that applications can rely on.
- User input is mapped through base and extended remote control functions, including colour keys, transport keys, number keys, Select, Cancel, Help, and Text.
- Resident programs provide built-in functions for dates, strings, service selection, reference checks, presentation information, interaction channel status, hybrid file system setup, and developer utilities.
- The profile also adds PVR extension resident programs for booking, cancelling, and listing recordings.
For implementers, this means the receiver must offer the same action set and built-in behaviour that the broadcast applications expect, especially for navigation, service selection, and PVR control.
Graphics, video, and text presentation
Clauses 12 and 13 define how the receiver displays visible objects, video, subtitles, fonts, and text. They cover the graphics plane, colour handling, transparency, HD graphics behaviour, character encoding, font support, and text layout.
- The graphics plane must support at least 256 colours, with reserved palette use for DVB subtitles.
- The HD graphics model defines how MHEG coordinates map onto HD presentation.
- Text is encoded in ISO/IEC 10646 with UTF-8, and the document specifies OpenType font handling, font resources, wrapping, flow, and text rendering behaviour.
- EntryField and HyperText have their own appearance and behaviour rules, including input handling and anchor presentation.
In practice, this is the part that makes multilingual text, downloadable fonts, subtitles, and HD overlays render in a consistent way across receivers.
Receiver behaviour for media, storage, and DVB-CI
Clause 14 sets receiver requirements for stream decoder management, aspect ratio handling, persistent storage, process priority, and interaction with the DVB Common Interface module system. Clause 15 then defines the file system profile for broadcast and IP content.
- The receiver manages stream decoders across application activation, deactivation, service changes, and presentation errors.
- Persistent storage is provided for application data, including file names and hybrid file system use.
- The receiver can retrieve content over HTTP from a server using an IP connection, and it supports HTTP/1.1 plus HTTP/TLS connections.
- Caching, authentication files, access to Internet servers, and TLS server authentication are covered so broadband content can be used safely in the same application model.
- DVB-CI interaction is defined so content and menu actions can work with a CI module.
For buyers and integrators, this is the part that tells you whether the receiver can mix broadcast assets, broadband assets, and CI-controlled services without breaking playback or access rules.
Names, URLs, and authoring practice
Clauses 16 and 17 define name mapping and authoring rules. They explain how receiver names, MHEG-5 object references, content references, service URLs, and duplicate services are handled, and they give guidance to authors on navigation, persistence, text usage, and video placement.
- Name mapping rules support broadcast service access, file references, and URL formats.
- Authoring guidance helps avoid confusion with navigator functions and supports predictable use of keys, video, subtitles, and persistent storage.
- The document also includes practical advice for handling dynamically updated content, object carousels, and content retrieval timing.
For application creators, this is the part that reduces compatibility problems caused by naming, navigation, and service-selection choices.
What terms does kSIST prES 202 184 V2.1.1:2010 define?
- access unit - A coded representation of a presentation unit.
- on screen display - Graphical information generated locally by the equipment and shown to the user.
- original_network_id - A unique identifier of a network.
- service provider - The broadcaster.
- Interoperable Object Reference (IOR) - A reference used to identify and access an object in the object carousel and service model.
- Hash Message Authentication Code (HMAC) - A keyed hash used in authentication-related processing.
- Personal Video Recorder (PVR) - A recorder managed by the PVRExtension for booking and listing events.
Who uses kSIST prES 202 184 V2.1.1:2010?
kSIST prES 202 184 V2.1.1:2010 is used by people who build, test, and operate MHEG-5-based interactive TV systems.
Typical users include:
- receiver manufacturers and chipset or middleware teams implementing the engine profile
- broadcast application developers authoring menus, information services, and interactive graphics
- service providers and platform engineers defining signalling, boot behaviour, and content delivery
- QA, interoperability, and certification labs checking receiver behaviour against the profile
- system integrators working with broadcast file systems, broadband retrieval, CI modules, or PVR features
In practice, these roles use the document to decide what a receiver must support, how applications should be authored, and how services should behave after tuning, launch, or content retrieval.
What changed in kSIST prES 202 184 V2.1.1:2010 from the previous edition?
kSIST prES 202 184 V2.1.1:2010 incorporates corrigenda from implementation of V 1.1.1. It also extends the profile for HD operation, broadband interaction-channel connection, enhanced font rendering, PVR and DVB-CI interaction, and additional character repertoire including Chinese and Polish.
Which standards are used with kSIST prES 202 184 V2.1.1:2010?
kSIST prES 202 184 V2.1.1:2010 builds on several external standards and companion documents:
- ISO/IEC 13522-5 - the base MHEG-5 hypermedia presentation system and object interchange format
- ISO/IEC 10646 - the character repertoire and UTF-8 encoding used for text and input
- ISO/IEC 10918-1 - JPEG bitmap coding
- JFIF - the file exchange format used with JPEG bitmaps
- ISO/IEC 13818-6 - DSM-CC, used for object carousels, sections, modules, and transaction handling
- ISO/IEC 14496-22 - Open Font Format, used for downloadable fonts
- ETSI TS 101 699 - DVB Common Interface extensions referenced for DVB-CI interaction
- EN 300 468 - DVB Service Information terms and identifiers used in signalling and name mapping
- RFC 2616 - HTTP/1.1, used in the IP content access profile
- TR 101 202 - referenced for the carousel_id_descriptor format identifier
These references provide the base MHEG-5 language, transport and service signalling, font and text encoding, and IP delivery profile that the broadcast profile depends on.
What does the kSIST prES 202 184 V2.1.1:2010 document contain?
The document contains tables for supported classes, feature strings, content formats, user input registers, engine events, resident programs, and mapping rules. It also contains signalling descriptors and step-by-step procedures for auto-boot, service acquisition, and object location.
Several figures illustrate the basic architecture, the engine interaction model, remote control function groups, quarter-screen video presentation, and HD graphics mapping. Clause 11.12 gives ASN.1-style extensions to the MHEG-5 language, while clause 15.2 and clause 15.3 give object-carousel, stream, and association-tag handling logic.
Annex A provides informative examples for authoring and presentation behaviour, and the text includes an informative rendering example for HD text layout. Together, these materials show not just what to implement, but how the profile is expected to behave in real receiver and authoring workflows.
