kSIST prES 202 184 V2.2.1:2011

• Abstract:

  The document is updated to include support for encrypted content delivery by back channel, some changes to the key handling functionality and other minor additions. The editorial format will be improved and a section currently duplicating TS 102 809 will be removed and the duplicated specification will be referenced.

Overview

kSIST prES 202 184 V2.2.1:2011 defines the MHEG-5 Broadcast Profile, a standard developed by SIST and based on the European Telecommunications Standards Institute (ETSI) ES 202 184. This document refines and extends the MHEG-5 standard widely used in interactive digital television (iDTV) environments, especially within DVB (Digital Video Broadcasting) systems. The 2011 update incorporates support for encrypted content delivery via back channels, improves key handling mechanisms for security, and references the relevant TS 102 809 specification to harmonize industry implementation. The revised profile also streamlines editorial content for clarity and removes duplicate sections.

Key Topics

• MHEG-5 Core Architecture
  Describes the foundational architecture for running interactive applications in digital broadcast and hybrid environments.
• Content Delivery and Formats
  Supports static and streaming content types including bitmaps (PNG, MPEG-2 I-frames), audio, video, text, and subtitles.
• Transport Protocols
  Details on delivery mechanisms for broadcast and broadband, enabling reliable multimedia distribution across terrestrial and IP-based networks.
• Application Lifecycle Management
  Defines mechanisms for launching, auto-booting, terminating, and persisting MHEG-5 applications, supporting robust user experiences.
• Security and Encrypted Content
  Enhanced methods for handling encrypted content delivery over back channels, with changes to key management to maintain secure operation.
• Signalling and Interoperability
  Specifications for application, service, and network-level signalling to ensure seamless application deployment and integration.
• User Interaction
  Supports comprehensive remote control and user input functions, ensuring accessibility and interaction with broadcast-triggered applications.
• Hybrid and Persistent Storage
  Hybrid file system management and persistent storage options allow for the extension of application functionality.
• Editorial and Organizational Enhancements
  Improved document structure for better usability and cross-referencing of related technical specifications (e.g., TS 102 809).

Applications

The MHEG-5 Broadcast Profile is essential for enabling interactive services and middleware in digital television ecosystems. Key practical applications include:

• Interactive TV broadcasting:
  Delivers interactive applications such as electronic program guides (EPGs), quizzes, voting, and on-demand information.
• Hybrid Broadcast-Broadband Services:
  Supports integration of broadcast content with IP-based services, enabling advanced use cases like catch-up TV and enriched media experiences.
• Secure Content Distribution:
  Facilitates protected delivery of premium services and subscription content, leveraging encrypted back channels and key handling improvements.
• Standards-Based Platform Integration:
  Promotes vendor interoperability and cost reduction by allowing set-top boxes, TVs, and middleware platforms to implement a common profile.

Related Standards

The MHEG-5 Broadcast Profile is designed for compatibility and integration with various broadcasting and networking standards:

• ETSI ES 202 184 - The foundational European standard for MHEG-5 profiles.
• TS 102 809 - Referenced for data broadcast and hybrid service delivery protocols.
• DVB Standards - Including DVB-T (terrestrial) and DVB-IP for transport.
• MPEG Standards - For audio and video coding compatibility.
• Other Middleware Specifications - Ensuring conformance across interactive TV devices and services.

For the latest updates and official documentation, consult the ETSI portal or your national standards organization.

Keywords: MHEG-5, DVB, digital broadcasting, interactive TV, encrypted content, broadcast profile, middleware, IP delivery, security, persistent storage, ETSI.
