kSIST prES 202 184 V2.2.1:2011 is SIST’s reference to ETSI ES 202 184 V2.2.1, MHEG-5 Broadcast Profile. It specifies how MHEG-5 interactive TV applications behave in broadcast receivers, including application startup, signalling, graphics, text, storage, file systems and receiver interaction. It is aimed at broadcast receiver implementers, interactive TV application authors, and anyone checking whether a receiver or application matches the MHEG-5 broadcast profile.
What does kSIST prES 202 184 V2.2.1:2011 specify?
kSIST prES 202 184 V2.2.1:2011 specifies a complete system for enhanced interactive TV in a broadcasting context. The document states that, unless otherwise stated, the functionality is mandatory, and it includes a local implementation note plus an extension for co-existence with broadcast-triggered native applications.
The standard is organized from general scope and references through architecture, signalling, engine profile, graphics, text, receiver requirements, file system profile, name mapping and authoring rules. Annex A gives examples and guidance, while Annex B allocates codes used with the profile.
| Annex | What it covers |
|---|---|
| Annex A | Informative examples and guidance for visual appearance, user navigation, channel selection and use of video within an information service |
| Annex B | Normative allocation of codes for use with the present document, including application type codes and UniversalEngineProfile(N) |
What are the key requirements of kSIST prES 202 184 V2.2.1:2011?
Application lifecycle and signalling
kSIST prES 202 184 V2.2.1:2011 defines how a receiver finds, launches and keeps track of an MHEG-5 application. Clause 8 covers launching, terminating, auto-boot, application context, accessible file systems, service tunes and application stacking; clause 9 defines application-level, service-level and network-level signalling.
In practice, this means the receiver must be able to identify the right application for the current service, follow PMT and ServiceGateway signalling, and continue an application across service changes when required. Clause 9.3 names the descriptors and sub-descriptors used for auto-boot identification, ServiceGateway acquisition and locating the initial object.
MHEG-5 engine profile
Clause 11 gives the engine profile that a compliant receiver shall support. It ties the receiver to ISO/IEC 13522-5 and sets out the supported class set, feature set, content data encoding, user input model, engine events, protocol mapping, resident programs, data type limits and language extensions.
This matters because implementers have to support the defined MHEG-5 classes and their behaviours, not just display content. Clause 11.4 includes GetEngineSupport feature strings, and later parts cover stream formats, encrypted non-linear streams, interaction with broadcast-triggered native applications, and the resident programs used for service selection, date and time, text handling, persistent storage, hybrid file systems, and PVR functions.
Graphics, video and presentation
Clause 12 defines the graphics model. The graphics plane is used for visibles other than video streams and MPEG I-frame bitmap objects, and it shall support at least 256 colours. The clause also reserves palette areas for MHEG-5 applications, DVB subtitles and manufacturer use, and it sets out colour representation, transparency, overlapping visibles, PNG bitmaps, MPEG-2 stills and H.264/AVC stills.
For a receiver manufacturer, this means presentation behavior is part of conformance. Clause 12.10 specifies how visibles appear while content is being retrieved, and clause 12.11 defines the high definition graphics model for receivers that can decode and present HD resolution video, including mapping from the MHEG application coordinate system to the graphics plane.
Text, entry fields and hypertext
Clause 13 defines how text is encoded and rendered. It uses ISO/IEC 10646 and UTF-8, covers font downloading and embedded fonts, and sets rules for text flow, wrapping, truncation, line placement and tabulation. It also covers EntryField behaviour, character entry, numeric input, SMS entry method and HyperText anchors.
In practice, authors and implementers must align on font availability, supported characters and user editing behavior. This is important for on-screen text fields, programme information, menus and clickable text, especially where input comes from remote-control keys.
Receiver behavior, storage and external systems
Clause 14 sets receiver requirements for stream decoder management, user control of linear content decoders, aspect ratio handling, persistent storage, true persistent storage, resource limits, process priority and DVB Common Interface module interaction. The clause also includes the handling of IC stream buffering and HD graphics bitmap requirements.
This means a compliant receiver is not only rendering content, but also managing decoder state, user control, and storage resources in a defined way. The document states persistent storage requirements and also defines true persistent storage for receivers that implement InteractionChannelExtension.
File system profile and security-related functions
Clause 15 specifies the file system profile for broadcast and interaction-channel content. It covers the broadcast file system, object carousel profile, DSM-CC sections, data carousel messages, BIOP object messages, stream events, Interoperable Object References, module mapping, transparent cache behavior, HTTP profile, hybrid file system caching, synchronous file loading and access control to Internet servers.
This is the part implementers use when they need to acquire, cache, identify and map content objects. Clause 15.13 also covers application signing certificates, signature verification and authentication file formats, and clause 15.16 covers HTTP profile support for delivering encrypted streams.
Name mapping and authoring rules
Clause 16 defines how names are mapped within the receiver, including MHEG-5 component tags, object references, GroupIdentifier and ContentReference rules, file reference structure and URL formats for broadcast services. Clause 17 then gives authoring rules and guidelines for user inputs, subtitles, video placement, persistent storage names, checking references, stream events, file-system structure and HD presentation.
These clauses matter to content authors because they reduce ambiguity between content, service names, file names and broadcast URLs. They also explain how to avoid conflicts with receiver navigation and other on-device functions.
What terms does kSIST prES 202 184 V2.2.1:2011 define?
- Application-level signalling - signalling carried with the application so the receiver can identify and start the intended MHEG-5 application.
- ServiceGateway object - the object used in service acquisition to locate the application content and, if needed, the initial object.
- Interaction Channel (IC) - the return path and associated file system used for interactive requests and content exchange.
- Common Interface (CI) - the DVB module interface referenced by the document for module interaction and CI-sourced file systems.
- Personal Video Recorder (PVR) - the extension used for booking, cancelling and listing recorded events.
- Service Information (SI) - service and event information used by resident programs such as
SI_GetServiceInfoandSI_GetEventInfo. - Interoperable Object Reference (IOR) - a reference format used to locate objects in object-carrier and service-gateway workflows.
Who uses kSIST prES 202 184 V2.2.1:2011?
Broadcast receiver manufacturers use this standard to implement the MHEG-5 engine, graphics model, storage behavior and signalling correctly. Middleware and platform engineers use it to map broadcast services, object carousels, stream decoders and interaction-channel functions into the receiver.
Interactive TV application authors use it to design applications that launch reliably, respond to remote-control input, handle text and hypertext, and survive service changes. Test laboratories, quality managers and buyers use it to check whether a product supports the expected MHEG-5 broadcast profile, including the required resident programs, file-system behavior and presentation rules.
What changed in kSIST prES 202 184 V2.2.1:2011 from the previous edition?
This version updates the MHEG-5 Broadcast Profile with support for encrypted content delivery by back channel, changes to key handling functionality and other minor additions. The editorial format is also improved, and a section that duplicated TS 102 809 is removed and replaced by a reference to that specification.
