To prepare international publications in the field of audio, video and multimedia systems and equipment.
These publications mainly include specification of the performance, methods of measurement for consumer and professional equipment and their application in systems and its interoperability with other systems or equipment.
NOTE: Multimedia is the integration of any form of audio, video, graphics, data and telecommunication and integration includes the production, storage, processing, transmission, display and reproduction of such information.
The Advisory Group on Strategy (AGS) is charged with the design and development of long term strategies for TC 100 for the standardization of digital multimedia systems and equipment.
To meet this objective, the AGS advises and recommends action on long-term strategic plans and directions for organizational structure and procedures for more effective standards development.
The AGS will provide leadership to enable improved cooperation between industry and TC100 by creating the strategic plans, which will strengthen the relevance of TC100 standardization activities.
The AGS reports directly to the Chairman of TC100.
TC 100/AGS acted as an alternative to Sector Boards (document 140/AC:1999 paragraph 5). However, in accordance with the disbandment of Sector Board, the AGS became one of genuine TC 100 groups.
The members of the AGS include:
Persons representing industry associations, where the members of the AGS cover global regions. Regions include: America, Europe, Asia and Oceanic. The AGS reviews and considers additional members periodically.
The Chairman, Secretary(ies) of TC 100.
IEC Central Office representative to give a strong support of the IEC Central Office.
Sound system equipment – Loudspeakers - Acoustical (Output based) measurements
This International Standard applies to passive and active sound systems such as loudspeakers, headphones, TV-sets, multi-media devices, personal portable audio devices, automotive sound systems and professional equipment. The device under test (DUT) may be comprised of electrical components performing analogue and digital signal processing prior to the passive actuators performing a transduction of the electrical input into an acoustical output signal. The standard describes only physical measurements which assess the transfer behaviour of the DUT between an arbitrary analogue or digital input signal and the acoustical output at any point in the near and far field of the system. This includes operating the DUT in both the small and large signal domains. The influence of the acoustical boundary conditions of the target application (e.g. car interior) can also be considered in the physical evaluation of the sound system. The standard does not assess the perception and cognitive evaluation of the reproduced sound and the impact of perceived sound quality.
Specification of the radio data system (RDS) for VHF/FM sound broadcasting in the frequency range from 87,5 MHz to 108,0 MHz
This International Standard describes the Radio Data System, RDS, intended for application to VHF/FM sound broadcasts in the range 87,5 MHz to 108,0 MHz which may carry either stereophonic (pilot-tone system) or monophonic programmes ( see clause 2 – Normative references ITU-R Recommendations BS 450-3 and BS 643-2). The main objectives of RDS are to enable improved functionality for FM receivers and to make them more user-friendly by using features such as Programme Identification, Programme Service name display and where applicable, automatic tuning for portable and car radios, in particular. The relevant basic tuning and switching information therefore has to be implemented by the type 0 group (see 184.108.40.206), and it is not optional unlike many of the other possible features in RDS.
Visible light beacon system for multimedia applications
This International Standard is applicable to a visible light beacon system for multimedia applications, which is a system for providing various applications such as data transmission through multimedia devices, identification of matters, providing positional information, and establishment of various guiding systems by radiation transmission of simple information or ID information unique to the visible light source among visible light sources ubiquitously surrounding the facility. It specifies a single directional visible light communication system using visible light as the transmission medium named 'Visible light beacon system for multimedia applications'. It aims at establishing a unified standard concerning the lower communication layer common to these applications, and does not deal with upper communication layers which depend upon individual applications.
MIDI (MUSICAL INSTRUMENT DIGITAL INTERFACE) SPECIFICATION 1.0 (ABRIDGED EDITION, 2015)
This International Standard specifies a hardware and software specification which makes it possible to exchange symbolic music and control information between different musical instruments or other devices such as sequencers, computers, lighting controllers, mixers, etc.
For this proposal, NP and CDV simultaneous circulation is applied given in 2.3.4 of the IEC Supplement of the ISO/IEC Directives.
This International Standard applies to micro-speakers used in portable electronic devices. Usually, the size of the vibration area is not greater than 40 mm. This also applies to loudspeaker systems (known as "box"), which consist of one or more loudspeaker drive units provided with an enclosure. This standard provides the characteristics of micro-speakers that need to be specified as well as the relevant methods of measurement for micro-speakers that use sinusoidal signals, or noise, or impulsive signals. The main characteristics include, but are not limited to, impedance, amplitude frequency response, distortion, and power handling.
Multimedia Vibration Audio Systems - Method of measurement for audio characteristics of audio actuator by pinna-conduction
This International Standard specifies measurement method for sound transmission performance of audio actuator by pinna-conduction. Audio actuator is device that designed to provide vibration to tissue around pinna (near the tragus) and to generate sound in ear canal. Audio actuator is widely used for headphones and loudspeakers of mobile phones.
IEC TR 63094: Multimedia systems and equipment – Multimedia signal transmission – Dependable line code with error correction
This document specifies the line code 4b/10b for dependable multimedia signal transmission required for complex machines, such as robots and automobiles. This document corresponds to the functions specified in layer 1 to layer 2 of the OSI reference model (ISO/IEC 7498).
The purpose of this document is to facilitate the development and use of the 4b/10b in dependable systems by providing a line code protocol. This document provides a line code protocol for interconnections among distributed real-time systems, including embedded systems, control systems, amusement systems, robot systems, and intelligent buildings. The 4b/10b can achieve the line code with ECC (error code correction). The 4b/10b is the line code that realizes embedded clock, DC balance, error detection and error correction at a time, which was not able to satisfy these functions in one codec by conventional schemes, so that the 4b/10b line code can achieve highly reliable and dependable digital communications.
