DLNA INTEROPERABILITY GUIDELINES VERSION 1.5 PDF

DLNA Summary The Digital Living Network Alliance is an international, cross-industry collaboration of consumer electronics, computing industry and mobile device companies. Members of DLNA share a vision of wired and wireless interoperable networks where digital content such as photos, music, and videos can be shared through consumer electronics CE , personal computers PCs , and mobile devices in and beyond the home. DLNA is focused on delivering an interoperability framework of design guidelines based on internationally recognized open industry standards together with a certification and logo program to officially verify and validate the conformance and interoperability of compliant products for consumers. The current guidelines expand the capabilities of the DLNA-defined network to include more device classes and functional capabilities — including printers, mobile devices, controllers, uploaders and downloaders.

DLNA Link Protection is defined as the protection of a content stream between two devices on a DLNA network from illegitimate observation or interception using the protocols defined within this document.

Content protection is an important mechanism for ensuring that commercial content is protected from piracy and illegitimate redistribution. Link Protection is a technique that enables distribution of protected commercial content on a home network, thus resulting in greater consumer flexibility while still preserving the rights of copyright holders and content providers.

The guidelines in this document reference existing technologies for Link Protection and provide mechanisms for interoperability between different implementations as well as integration with the DLNA architecture. They are based on so named DLNA DRM Interoperability Solutions DIS , which are defined as methods to enable the secure transfer and use of protected commercial content among different implementations on network media devices.

This content could be protected by different content protection technologies, in this part are referred to as DRMs in short.

The guidelines are not intended to replace or disable other interoperability mechanisms that could already be in place, e. For a device to be compliant with a Device Profile, it has to conform to all of the guidelines listed for that Device Profile In practice, Device Profiles reference existing optional or recommended DLNA guidelines, that enable certain features, and makes those DLNA guidelines mandatory within the context of a Device Profile.

A Device Profile can also provide some additional guidelines that complement or modify existing DLNA guidelines for a feature. VidiPath is an extension of the DLNA guidelines that will allow 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 interface to a commercial content service provider.

Since different regions of the world have different requirements for commercial content, there are multiple CVPs defined. Through native integration, HTML5 enables the repurposing of single codebases, resulting in reduced development costs and the provision of a unique UI for every device.

The guidelines are based on a device authentication solution, which is defined as methods to enable authentication of a client device as DLNA Certified. Methods are included to allow a client device to authenticate a server device as trusted by a Certificate Authority.

A user interface is required on the controller side that will allow user access to Diagnostics data and capabilities. The user might be an Operator accessing the Diagnostics application through a TR an application layer protocol for remote management of end-user devices management interface, or a technician or end-user accessing it through a browser or screen interface. Client rendering devices can select the appropriate timed segments e.

Power savings is modular within a physical device. In the context of DLNA networked devices each physical network interface can have various power modes, some of which can allow Layer 2 or Layer 3 connectivity to still be present, even when many of the other components of the device are powered down.

Other physical components, such as screens, hard drives, and similar resources, can also support different power modes.

Examples include TVs, stereos and home theaters, wireless monitors and game consoles. It is possible for a single device e. Content does not stream from or through the DMC. Examples include tablet computers , Wi-Fi enabled digital cameras and smartphones.
