Summary Q&A

The DLNA Technology Solution
DLNA Interoperability Guidelines
Connectivity Ethernet Wireless
JPEG, LPCM, MPEG2 UPnP AV 1.0 UPnP Device Architecture 1.0 HTTP 1.0/1.1 IPv4 Protocol Suite Wired: 802.3i, 802.3u Wireless: 802.11a/b/g

Networking IP foundation

Allows applications to run over different networks Enables connecting devices to the Internet Widely used and costeffective

Media Transport

HTTP is the baseline transport for media streaming or transfer HTTP must be supported by all digital home devices that source or render media content RTP is optional
Device Discovery & Control UPnP Device Architecture 1.0
Device and service discovery through Auto-IP and DHCP
Media Management UPnP AV 1.0 Device and service descriptions

Examples:

MediaServer MediaRenderer RenderingControl ContentDirectory
Media Formats Required formats establish an interoperability baseline Mandatory and optional formats for transport and rendering Content in an optional format must be transcoded to the corresponding required format, if necessary for content interchange between devices
Link Protection DTCP/IP Required to establish an interoperability baseline WMDRM-ND optional to provide access to additional content
DTCP/IP, WMDRM-ND JPEG, LPCM, MPEG2 UPnP AV 1.0 UPnP Device Architecture 1.0 HTTP 1.0/1.1 IPv4 Protocol Suite Wired: 802.3i, 802.3u Wireless: 802.11a/b/g
DLNA Link Protection Guidelines

DTCP/IP required

Defines link protection technology for the secure handling of commercial content
Establishes a Secure Authenticated Channel (SAC) Generates an ephemeral session key that updates periodically Supports streaming only, with limited copy permissions:
Copy one time Never copy Copy restriction right not asserted

Summary

Ultimate Challenge and Goal
Consumer digital AV product choice should be a price, design, feature, function, brand choice, not a technology choice
Utility of products and access to content should not be constrained by the specific vendor or the technologies that are or are not incorporated
Consumer content choice should be a personal, emotional choice, not a technology choice
Access to content from digital AV products should not be constrained by where or how you purchased the content or by the devices you own or who manufactured them
The rights of all stakeholders in the content-to-device value chain must be protected
Consumers should get what they pay for by participating in a healthy ecosystem comprised of broad and diverse product, service and content offerings driven and sustained by growing business opportunity
