IEC 62516-1:2009

Overview

IEC 62516-1:2009 specifies the basic requirements for terrestrial digital multimedia broadcasting (T-DMB) receivers. The standard defines the characteristics and minimum required performance for T-DMB terminals, covering T-DMB system information, video, audio and MPEG‑4 BIFS (Binary Format for Scene) data. It provides guidance to ensure interoperability, consistent receiver behavior and predictable quality of service for T‑DMB deployments.

Key Topics

• Scope and normative references: Establishes required references (e.g., MPEG, AVC/H.264, JPEG2000 and DAB-related ETSI/IEC documents) that underpin T‑DMB receiver implementation.
• Receiver implementation summary: Functional block descriptions and a conceptual video multiplexer as an extension of DAB systems.
• Audio and video services: Minimum performance and operational rules for decoding and presenting audio and video streams, including use of Advanced Video Coding (AVC/H.264) and MPEG‑4 based audio approaches (e.g., BSAC, HE‑AAC v2 referenced in the standard).
• MPEG‑4 BIFS and auxiliary data: Handling of scene description and auxiliary data services (images, data objects) and receiver structures for processing these services.
• Synchronization and timing: Requirements for audio/video synchronization, object synchronization in video services, composition and presentation timing (CTS, PTS, PCR concepts).
• Operational performance metrics: Channel switch time, initial access delay, RF input and minimum RF performance requirements, selectivity and adjacent-channel behavior.
• Two‑layer video architecture and decoder features: Architectural guidance for multiplexing and decoder handling of AVC features applicable to T‑DMB.

Applications

IEC 62516-1 is intended for:

• Receiver manufacturers and chipset designers implementing T‑DMB-capable mobile, portable and fixed receivers.
• Broadcast system integrators and network operators ensuring transmitted content is compatible with minimum receiver capabilities.
• Test laboratories and certification bodies creating conformance tests and RF/functional validation procedures.
• Product managers and regulatory bodies defining product specifications, procurement requirements or compliance policies for T‑DMB services.

Practical benefits include consistent user experience, reliable audio/video/data playback, faster time-to-market for T‑DMB products and clearer interoperability rules between broadcasters and receiver vendors.

Related Standards

Key referenced standards include (non‑exhaustive):

• IEC 62104 (DAB receiver characteristics)
• ISO/IEC 14496 series (MPEG‑4 systems, audio, BIFS)
• ISO/IEC 14496‑10 / ITU‑T H.264 (AVC)
• ISO/IEC 15444‑1 (JPEG 2000)
• ETSI TS/EN documents for DAB/T‑DMB system and service specifications
