24、IGITAL LIVING NETWORK ALLIANCE (DLNA) HOME NETWORKED DEVICE INTEROPERABILITY GUIDELINES Part 5: DLNA Device Profile guidelines 1 Scope This part of IEC 62481 specifies guidelines that define various DLNA Device Profiles. A Device Profile is a collection of DLNA capabilities and features within a DLN
25、A device. A device is compliant with a Device Profile, when it conforms to all the guidelines listed for that Device Profile. In practice, Device Profiles reference existing optional or recommended DLNA guidelines, that enable certain features, and make those DLNA guidelines mandatory within the con
26、text of a Device Profile. A Device Profile may also provide some additional guidelines that complement or modify existing DLNA guidelines for a feature. A particular type of the DLNA Device Profile is the Commercial Video Profile (CVP). A CVP Device Profile is an extension of the DLNA guidelines tha
27、t allows content from service providers and multichannel video programming distributers to be distributed on the DLNA network. DLNA Commercial Video Profiles (CVPs) are defined as Device Profiles that consistently enable commercial content that enters the home network through a gateway device via an
28、 interface to a commercial content service provider. Since different regions of the world have different requirements for commercial content, multiple CVPs are defined. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensa

34、e.g., Device Profile). Any lowercase uses of these words have the normal technical English meanings. 4 Networking architecture, device models and guideline conventions 4.1 DLNA home networking architecture See Clause 4 in IEC 62481-1:2013 for a full description of the DLNA home networking architectu

36、cribes the format of the guidelines for DLNA Device Profiles. Applicability of a referenced guideline to a specific Device Class is defined both by the attribute table of the guideline that references it, as well as by the “applicable Device Classes” column of the Device Profile definition in the ta
37、ble at the top of each Device Profile clause. 5.2 Defined Device Profiles Each Device Profile begins with a table that briefly describes it. This table also indicates which DLNA Device Classes the Device Profile applies to. Although a guideline, as defined, could apply to additional Device Classes,
38、the defined Device Profile only provides for the guidelines applicability to the Device Classes listed in conjunction with the Device Profile. The definition of a Device Profile in this table (the applicable Device Classes and the Device Profile name) is a normative definition of that Device Profile
39、. The Device Casses that a guideline applies to within the context of a Device Profile are the intersection of the Device Classes the guideline applies to (from its attribute table) and the Device Classes that the Device Profile applies to (from its introductory table). See 7.1 in IEC 62481-1:2013 f
