IEC 62766-4-2:2017

Overview

IEC 62766-4-2:2017 is an international standard developed by the International Electrotechnical Commission (IEC) as part of the IEC 62766 series. This document, titled Consumer terminal function for access to IPTV and open internet multimedia services - Part 4-2: Examples of IPTV protocol sequences, serves to provide informative examples for features defined in IEC 62766-4-1. The focus is on the protocol sequences that enable consumer terminals to access IPTV (Internet Protocol Television) and open internet multimedia services efficiently over managed and non-managed networks. The examples help system engineers, integrators, and service providers implement, troubleshoot, and optimize IPTV service functions and interactions.

Key Topics

• IPTV Protocol Sequences: Illustration of typical interactions between consumer terminals (such as set-top boxes) and multimedia service providers.
• Content on Demand (CoD) Protocols: Examples of Real-Time Streaming Protocol (RTSP) use for managed and unmanaged IPTV network models.
• Content Reporting and Management: Protocol call flows for content access reporting, critical for user analytics and content protection.
• Digital Media Purchase Procedures: Outlines steps and checks for purchasing digital content, including prevention of repeat billing.
• Pay Per View (PPV) Services: Protocol sequences for user-initiated PPV service access, both with and without existing scheduled content sessions.
• Network-based Content Time Shift: Examples of how users can activate and manage time-shifted viewing of network-recorded content.

Applications

IEC 62766-4-2:2017 offers high practical value, particularly for:

• Equipment Manufacturers and Developers: Implementing interoperable consumer terminals capable of seamless IPTV and internet multimedia service access.
• Service Providers: Integrating certified terminals, optimizing network resources, and ensuring accurate billing and content delivery.
• System Integrators: Designing solutions where protocol compliance and interoperability with managed networks (e.g., telecom-operated IPTV) and unmanaged internet environments are required.
• Standards-based Testing: Facilitating conformance testing by providing reference call flows and transaction sequences.

The document’s detailed protocol sequence examples help organizations:

• Reduce implementation errors during integration of IPTV service functionalities such as content purchase, reporting, and parental control.
• Ensure consistency and reliability in user-facing services, such as digital content purchase confirmations, parental controls activation, and notification services.
• Support, troubleshoot, and upgrade existing solutions by referencing standardized functional flows.

Related Standards

IEC 62766-4-2:2017 is closely associated with a number of other international standards, including:

• IEC 62766-4-1: Outlines the base protocols for consumer terminal access to IPTV and open internet multimedia services; should be used in conjunction with Part 4-2.
• IETF RFC 3261: Defines the Session Initiation Protocol (SIP) used for signaling and controlling multimedia communication sessions.
• IETF RFC 3455, 3588, 3611, 4825: Standards for SIP Private Headers, Diameter Base Protocol, RTP Control Protocol Extended Reports, and XML Configuration Access, respectively.
• 3GPP TS 29.199-4: Specifies Open Service Access (OSA) for Parlay X web services, relevant for messaging.
• Broadband Forum TR-135: Provides a data model for TR-069 enabled set-top boxes, essential for device management in IPTV environments.
