This second edition cancels and replaces the first edition (ISO/IEC 24752-1:2008), which has been technically revised.

18、of this part of ISO/IEC 24752. The main purpose of the revision is an alignment with recent developments in the web service area, in particular with the new ISO/IEC 24752-6, along with an overall simplification of the specified technologies. This part of ISO/IEC 24752 is one of a set of Internationa
19、l Standards to facilitate operation of information and electronic products through remote and alternative interfaces and intelligent agents. The purpose of ISO/IEC 24752-1 is to facilitate the development and deployment of a wide variety of devices (from different manufacturers) that can act as univ
20、ersal remote consoles (URCs) for an equally varied range of target devices and services (targets), also from different manufacturers. It allows users to control any number of information and electronic products in their environment. The targets include both devices and services. They can range from
21、things as simple as light switches and thermostats to more complex items such as audio-visual equipment, home appliances, in-car electronics, web services, and any other devices or services that can be controlled electronically (or via information technology). Targets can be in the same location as
22、the individual who desires to control the target through the URC, or at any distance from the URC/user as long as there is some type of network connection between the URC and the target. This is possible since a URC provides the user with all of the necessary controls as well as the prompts and othe
23、r information displayed by the target. The URCs could be software running on common mainstream devices such as personal computing and information technology devices (e.g. computers, laptops, tablet computers, smartphones, cell phones, or other telecommunications devices). They could also be function
24、s implemented in assistive technology devices, or they could be devices which were specially built to function as URCs. They could be devices which were built to function primarily as a remote console for a particular family of products (e.g. a remote console designed to be part of a home audio-visu
25、al system), but could also serve to control any other devices compatible with this part of ISO/IEC 24752. They are similar to the behaviour of universal remote controls today, except for the following: a) they have much greater function and scope, b) they synchronize with the target in both directio
26、ns (i.e. they can display the current status of the target), c) they do not need to be programmed by the user (since they will automatically discover devices that are controllable in a users vicinity, discover the abstracted user interface of the targets, and present it in the way preferred by the u
27、ser and their URC), and d) they can be used out of sight of the product they are controlling. The URCs could be all visual, all tactile, or all verbal in nature, or any combination thereof, because this International Standard specifies the content of a target user interface independently from the fo
28、rm in which it is presented. Thus, URCs could be designed that an individual could talk to and, through the URC, the user could have speech access to any compatible target listed above without any of these targets having any voice recognition or voice control functionality themselves. A person might
29、, therefore, be able to say to their URC, “Record channel 12 and show me Law and Order”. Or they could lie in bed and say, “Set the alarm to 6:30 AM, start brewing the coffee at 6:00 AM, and now set the home security system to active”. Or, if ones spouse is already asleep, a person could pick up the
30、ir smartphone or any other compatible URC device and accomplish these same tasks silently either by calling up control panels or by issuing the instructions in writing. NOTE The URC framework does not provide the natural language control, but would provide all of the information and control necessar
31、y for control by a natural language processing URC. Note that, although a URC implementation can involve hardware, requirements on this hardware such as safety and design requirements are not within the scope of this International Standard.

33、rt International Standard that facilitates operation of information and electronic products through remote and alternative interfaces and intelligent agents. This part of ISO/IEC 24752 defines a framework of components that combine to enable remote user interfaces and remote control of network-acces
34、sible electronic devices and services through a universal remote console (URC). It provides an overview of the URC framework and its components. 2 Conformance 2.1 URC A conforming URC shall conform to the URC requirements as specified in Clauses 4 and 8.
