1、 ANSI/CEA Standard Web-based Protocol and Framework for Remote User Interface on UPnP Networks and the Internet (Web4CE) ANSI/CEA-2014-B January 2011 NOTICE Consumer Electronics Association (CEA) Standards, Bulletins and other technical publications are designed to serve the public interest through
2、eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards, Bulletins and other tech
3、nical publications shall not in any respect preclude any member or nonmember of CEA from manufacturing or selling products not conforming to such Standards, Bulletins or other technical publications, nor shall the existence of such Standards, Bulletins and other technical publications preclude their
4、 voluntary use by those other than CEA members, whether the standard is to be used either domestically or internationally. Standards, Bulletins and other technical publications are adopted by CEA in accordance with the American National Standards Institute (ANSI) patent policy. By such action, CEA d
5、oes not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard, Bulletin or other technical publication. Note: The users attention is called to the possibility that compliance with this standard may require use of an invention covered by
6、 patent rights. By publication of this standard, no position is taken with respect to the validity of this claim or of any patent rights in connection therewith. The patent holder has, however, filed a statement of willingness to grant a license under these rights on reasonable and nondiscriminatory
7、 terms and conditions to applicants desiring to obtain such a license. Details may be obtained from the publisher. This CEA Standard is considered to have International Standardization implication, but the International Electrotechnical Commission activity has not progressed to the point where a val
8、id comparison between the CEA Standard and the IEC document can be made. This Standard does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of this Standard to establish appropriate safety and health p
9、ractices and to determine the applicability of regulatory limitations before its use. (Formulated under the cognizance of the CEA R7 Home Network Committee.)

35、ns and Definitions 3.1 Conventions The following keywords are used to differentiate levels of requirements and optionality, as follows: SHALL - A keyword that indicates a mandatory requirement. Designers are required to implement all such mandatory requirements to assure interoperability with other
36、products conforming to this standard. Equivalent to the term “MANDATORY” OR “(MAN)”. SHOULD - A keyword that denotes flexibility of choice with a strongly preferred alternative. Equivalent to the term “RECOMMENDED”. MAY - A keyword that indicates flexibility of choice with no implied preference. Equ
37、ivalent to the term “OPTIONAL”. Obsolete - Indicates a requirement that has been either replaced or removed in this revision of the specification (as noted). Devices that need to remain compatible with previous revisions of this specification may be required to implement the previously stated behavi
38、or(s). It is expected that replaced requirements will support backward compatibility with previous revisions of CEA-2014. Updated - Indicates requirements with (minor) editorial changes and/or complementary information to the behavior specified by previous revisions of this specification. The change
39、s between CEA-2014 revision A and B are informatively described in Annex BB. yellow highlighting - used to draw special attention to subtle but important distinctions. All properties for the Javascript APIs defined in this document, excluding Annex I, SHALL be read-write, unless specifically marked
40、with keyword “readonly”. 3.2 Definitions and Acronyms For the purposes of this standard, the following definitions apply: 2-Box Model - Short for 2-Box Remote UI Configuration Model as described in Section 4.1.2. 3-Box Model - Short for 3-Box Remote UI Configuration Model as described in Section 4.1
41、.3. 3rdParty Notification - The Remote UI Server is able to send a notification message that appears on the Remote UI Client at any time, without the need to interact with the Remote UI Server, e.g. to receive caller ID messages, printer status messages, etc. A/V Control Point (AVCP) - This is the u
42、nit of functionality that is responsible for setting up the connection between a compatible Digital Media Server and an A/V renderer. A/V Client/Renderer (AVC) - A device (or a group of cooperating devices) that is responsible for the actual rendering/playback of A/V content. If this device is disco
43、verable in an UPnP network, it is called a Digital Media Renderer (DMR). A/V Server (AVS) A device (or a group of cooperating devices) that offers A/V content. If this CEA-2014-B 9 device is discoverable in an UPnP network, it is called a Digital Media Server (DMS). Browser Area - The rectangular ar
44、ea as specified in Section 5.2.3 that the Remote UI Client has made available for rendering CE-HTML content served by a Remote UI Server. Digital Media Player (DMP) - A device (or a group of cooperating devices) that implements an A/V Control Point and has an A/V renderer. Digital Media Renderer (DM
45、R) - A device (or a group of cooperating devices) that implements the UPnP A/V MediaRenderer device template. Digital Media Server (DMS) - A device (or a group of cooperating devices) that implements the UPnP A/V MediaServer device template. i-Box Model - Short for i-Box Remote UI Configuration Mode
46、l as described in Section 4.1.1. i-Box Server - A Level 0 Remote UI Server that does not reside in the same subnet as the Remote UI client. In-Session Notification - The Remote UI Server is able to send a notification message during a UI interaction to update the UI dynamically without the need to r
47、eload the XHTML-page. Remote UI - A user interface offered by an application running on a Remote UI Server that can be accessed via the network by one or more Remote UI Clients. Remote UI Client (RUIC) - A device (or a group of cooperating devices) that provides a way of rendering and interacting wi
48、th one or more remote user interfaces. Remote UI Server (RUIS) - A device (or a group of cooperating devices) that offers one or more Remote UIs. UI Control Point (UICP) - This is the unit of functionality that is responsible for setting up the connection between a compatible Remote UI Server and Re
49、mote UI Client. UI Interaction - A period or consecutive periods of time when there is an active interaction between a Remote UI Client and a Remote UI Server. w.r.t. with respect to CEA-2014-B 10 4 Architectural Overview (Informative) This section describes the possible Remote UI Client and Server configurations. In addition, it pro
