4. Rally Technologies www.microsoft.com/rally CDS The CDS provides a logical structure for the media library available in the Server: ContainersItemsResources DMCs and DMPs retrieve media library information from a DMS using different CDS actions   Collection of other containers or items   Single entity that users perceive as one piece of content   Binary representation of the content (a file or a stream)

5. Rally Technologies www.microsoft.com/rally Windows CDS (partial view) ROOT (0) MUSIC (1) VIDEO (2) PICTURES (3) PLAYLISTS (12) All Music (4) Genre (5) Artist (6) Album (7) Folders (14) All Video(8) Genre (9) Actor (A) Series (E) Playlists (10) Folders (15) Rating (200) Album(7) Rating (101) All Pictures(B) Date Taken(C) Albums (D) Keyword (D2) Playlists (11) Folders (16) Rating (300) All Playlists(13) Folders (17)

6. Rally Technologies www.microsoft.com/rally Item and Resources One “Item” can have more than one “Resource” Example: The Item describes the movie “Terminator” Resource 1: MPEG-2 version Resource 2: WMV version Resource 3: Low res MPEG4 version Most implementations select only the first Resource (not the best approach) A good implementation selects a Resource based on Available bandwidth Native vs. Transcoded Receiver features (cell phone vs. TV, etc) …… ….. URI …… ….. URI

7. Rally Technologies www.microsoft.com/rally protocolInfo The most important attribute in DLNA! In a DMS, it describes all the server features per resource Divided in 4 fields: 1 st FieldDefines the streaming protocol (http vs. rtp/rtsp) 2 nd FieldEmpty 3 rd FieldMIME type 4 th FieldDLNA parameters: ProfileID Time Seek, Byte Seek, Server-driven play speeds Transcoding flag Streaming, Interactive, Background flags Others…

12. Rally Technologies www.microsoft.com/rally Typical sequence of operations 1. Get Media Library info 3. User selects content 4. Pass URI & metadata for selected item; Play 2. Send me the “Profiles” that you can play (protocolInfo) 5. Pause, Stop, Seek, FF, Rewind, etc 6. Adjust volume, brightness, etc

14. Rally Technologies www.microsoft.com/rally DLNA upgrades for DMR/DMC DMRs return a “protocolInfo” that includes the ProfileIDs they support DMRs always have available a default connection, a default AVT service, and a default RCS service DMCs pass the content URI but also must pass associated metadata DMCs can make seek requests to a DMR using Time or Byte information Actual content seek operations and play speed operations can happen locally (DMR) or with the help of a networked Server (DMS) DMRs have the means to communicate to DMCs the list of play speeds, and the flavor of seek operations available per resource Upgrades described in recently approved documents CR13, CR58, CR155

17. Rally Technologies www.microsoft.com/rally A sketch of the process Become a DLNA member Participate in plugfests Do internal testing; use the CTT tool Ensure compliance with pre-requisites (UPnP certification, Wi-Fi certification, etc) Contact DLNA to start the certification program Submit your device to Certification Labs After passing tests, get a DLNA Certificate A DLNA Certificate (version 1.5) will be a requirement for Networked Media Devices that apply for the new Certified for Windows Logo Program
