New Publications


IEC 62766-2-2 Ed. 1.0 (2016-12) Consumer terminal function for access to IPTV and open internet multimedia services - Part 2-2: HTTP adaptive streaming

specifies media formats for adaptive unicast content streaming over HTTP. Two HTTP adaptive streaming formats are specified. The first is based entirely on MPEG DASH. The second is the OIPF "HTTP adaptive streaming" (HAS) format, which is based upon 3GPP's release 9 adaptive HTTP streaming (AHS) format, with some profiling and extensions to add the features of media components and support for MPEG-2 transport stream content segment format. The latter format was specified before MPEG DASH had been published. It is retained due to usage in some legacy applications. Key words: Internet


IEC 62766-3 Ed. 1.0 (2016-12) Consumer terminal function for access to IPTV and open internet multimedia services - Part 3: Content metadata

specifies the aspects concerning content metadata.


IEC 62827-3 Ed. 1.0 (2016-12) Wireless power transfer - Management - Part 3: Multiple source control management

specifies methods and procedures to form groups for a spatial wireless power-transfer system. The group of spatial wireless power-transfer systems that include multiple power sources provides power transfer to receiving devices based on magnetic resonance technology. In order to achieve efficient power transfer to multiple receiving devices, this document also specifies methods and procedures to set, share, and control the conditions of power transfer between multiple power sources and receiving devices.


IEC TR 63071 Ed. 1.0 (2016-12) Power supplying scheme for wearable system and equipment

provides models and frameworks for the power-supplying scheme for wearable systems and equipment. This document does not specify power generating or energy harvesting methods and the devices themselves.


IEC 62944 Ed. 1.0 (2016-12) Audio, video and multimedia systems and equipment - Digital television accessibility - Functional specifications

specifies a set of principles and considerations for digital television products in support of older people and persons with disabilities in addition to mainstream users. The effect of following the principles and considerations as set out in this document is to ensure that the widest range of users can access, understand and use digital television products. These principles and considerations cover four main user profiles such as individuals with hearing impairments, individuals with sight impairments, individuals with mobility impairments and individuals with cognitive impairments.


IEC 62943:2017 Ed. 1.0 (2017-03) Visible light beacon system for multimedia applications

aims at establishing a unified standard concerning the lower communication layer common to multimedia applications, and does not deal with the upper communication layer which depends upon individual applications. This document specifies a unidirectional visible light communication protocol using visible light, named "visible light beacon system for multimedia applications".


IEC 62680-3-1 Ed. 1.0 (2017-03) Universal Serial Bus interfaces for data and power - Part 3-1: Universal Serial Bus 3.1 Specification

defines the latest generation USB industry standard, USB 3.1. The specification describes the protocol definition, types of transactions, bus management, and the programming interface required to design and build systems and peripherals that are compliant with this specification. USB 3.1 is primarily a performance enhancement to SuperSpeed USB 3.0 resulting in providing more than double the bandwidth for devices such as Solid State Drives and High Definition displays. It refers to Enhanced SuperSpeed as a collection of features or requirements that apply to both USB 3.0 and USB 3.1 bus operation. Additionally, where specific differences exist with regard to the USB 3.0 definition of SuperSpeed features or requirements, those differences will be uniquely identified as SuperSpeedPlus (or SSP) features or requirements – generally, “SuperSpeed” is in reference to 5 Gbps operation and “SuperSpeedPlus” is in reference to 10 Gbps operation.


IEC 60728-12 Ed.2.0 (2017-03) Pre release version Cable networks for television signals, sound signals and interactive services - Part 12: Electromagnetic compatibility of systems

(This Final Draft International Standard is an up to 6 weeks' pre-release of the official publication. It is available for sale during its voting period: 2017-03-17 to 2017-04-28. By purchasing this FDIS now, you will automatically receive, in addition, the final publication.)

IEC 60728-12:2017 applies to the radiation characteristics and immunity to electromagnetic disturbance of cable networks for television signals, sound signals and interactive services and covers the frequency range 0,15 MHz to 3,5 GHz. This second edition cancels and replaces the first edition published in 2001. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) IEC 60728-12 with its methods of measurement and EMC performance requirements is explicitly dedicated to “under operating conditions (in situ)” to ensure the ongoing EMC integrity of cable networks.
b) The first intermediate frequency range (1st IF range) for satellite signal transmission was extended to cover now frequencies from 950 MHz up to 3‍ 500 MHz.
c) The method of measurement and the requirements for in-band immunity were extended taking into account the new EMC environment due to the allocation of broadband wireless services in the frequency band 694 MHz to 862 MHz. As a consequence, the limits of in-band immunity were specified for analogue and additionally for digital signals in this frequency range.
d) The substitution method of measurement (power method) was deleted.
e) EMC measurements below 30 MHz were deleted.
f) New Annex D “Measurements at other distances than the standard distance of 3 m”.
g) New Annex E “GPS based leakage detection system for cable networks”.


IEC 62766-4-2 Ed. 1.0 (2017-04) Consumer terminal function for access to IPTV and open internet multimedia services - Part 4-2: Examples of IPTV protocol sequences

provides informative examples of features defined in IEC 62766-4-1.


IEC 62394 Ed. 3.0 (2017-04) Service diagnostic interface for consumer electronics products and networks - Implementation for ECHONET

specifies requirements for service diagnostic software to be implemented in products that incorporate a digital interface. The Service Diagnostic Interface (SDI) requires an external controller (exclusive or general-purpose/PC) into which service diagnostic software can be loaded. Parts of the controller software should be standardized while other parts should be unique to the manufacturer. The SDI is based upon ECHONET specification version 2.11, ECHONET Lite specification version 1.11, and APPENDIX Detailed Requirements for ECHONET Device objects Release G, because this interface will be used in future products. The use of this connection and existing communication protocols enable implementation in products at a low cost, with maximum flexibility and efficiency.
