GSO IEC 60948:2014 家用电子系统 (HES) 数字键盘

This standard is applicable to all kinds of equipment with numeric input used in homes, for example videotex terminals, household appliances, climate control and remote controls for TV, for recorders and for lights; excluding telecommunication terminals, data processing equipment and office machines, subject to CCITT E.161 and ISO 3791. This standard specifies a layout for numerical keyboards with three rows of three keys each and a fourth row with at least one key. The layout described in this standard is concerned only with the nominal relative positions of keys; it is not intended to define physical factors, such as keyboard slope, size and shape of keytops, nor the way in which the keytops are inscribed. The definition of such physical factors may be the subject of other standards.

GSO IEC TR 60728-6-1:2014 用于电视信号、声音信号和交互式服务的有线网络 第6-1部分：模拟光传输系统的系统指南

This part of IEC 60728 provides guidelines and procedures for determining the overall performance of optical transmissions systems used in cable networks for television signals, sound signals and interactive services. It is based on the requirements for optical equipment defined in IEC 60728-6 and should be used together with this standard. The information provided is meant to help field engineers and network planners (system designers) in planning and designing optical systems. Though this content is less dense than in a standard, basic knowledge about system parameters of cable networks is needed.

GSO IEC 62481-1:2014 数字生活网络联盟 (DLNA) 家庭联网设备互操作性指南 第1部分：架构和协议

This part of IEC 62481 specifies the core architecture and protocols of DLNA implementations. The interoperability guidelines consist of five parts covering Architecture and Protocols, Media Formats, Link Protection, DRM Interoperability Systems and Device Profiles. This part of IEC 62481 provides vendors with the information needed to build interoperable networked platforms and devices for the digital home. The necessary standards and technologies are now available to enable products to be built for networked entertainment centric usages. However, standards and technologies need to be clarified and options limited to ensure interoperability. The five parts of the DLNA Home Networked Device Interoperability Guidelines fulfill that role.

GSO IEC 62379-1:2014 网络数字视听产品的通用控制接口 第1部分：概述

This part of IEC 62379 specifies a control interface for products which convey audio and/or video across digital networks. Separate documents specify items specific to a particular type of traffic, a particular networking technology, or a particular class of application.

GSO IEC 62481-2:2014 DLNA 设备的互操作性指南 第2部分：DLNA 介质配置文件

This part of IEC 62481 describes DLNA Media Format Profiles applicable to the DLNA Device Classes defined in IEC 62481-1. Media Format Profiles are defined for each of the following media classes: Audio, Image, and AV. In addition, Profile ID values that identify media collections and printer XHTML documents are also introduced. The Profile ID is exposed in a server's Content Directory Service (CDS) to signal potential networked players or renderers the existence of a content item with particular coding and compression features defined precisely by the item's Profile ID.
