and another great way to help would be using the beebits "Test Suite" http://coherence.beebits.net/wiki/TestSuite and some new terminology too in the UPnP/DLNA world Audio/Video devices This chapter covers the three UPnP Audio/Video devices specified by the UPnP Forum. Together they build an infrastructure for distributing media content throughout a local network at home without the need of a complicated setup. MediaServer That is the place where all the media files are stored that are going to be published in the network. After the activation of the MediaServer it scans all resources (usually the file system) for media that should be shared. To ease the selection of media for the client/user the server has to provide some metadata about the shared files. Hence it needs to read all the shared files and index them according to the data found in ID3 tags, AVI containers etc. The collected data can be browsed or searched by the client/user. If a file matches the criteria of the client/user it is requested from the MediaServer and it starts to stream it to the device rendering the content. A MediaServer can be a computer with MediaServer software installed (i.e. [TVersity], see page 15), an intelligent network storage with a tiny MediaServer built-in (i.e. [TwonkyMedia?], see page 14) or another device that offers its data via an UPnP interface (i.e. [Nokia N80]). MediaRenderer The renderer takes the data that is streamed by the server and outputs it according to the media format. After activation and announcing itself in the network a MediaRenderer is waiting for a ControlPoint that is issuing commands to request and play a file. If such a command is received the renderer connects to the given MediaServer and retrieves the file. The data is decoded and sent to the output device, screen and/or speakers. While the playback is running the ControlPoint can still affect it and change for example the volume for audio playback or the contrast for video playback. MediaRenderers are rarely sold on their own. Typically renderer and ControlPoint are integrated within one device. They are available as computer programs, often in form of a MediaCenter? (i.e. [NeroHome?], see page 16), as audio clients having a WLAN connection (i.e. [NOXON 2 audio]) or as fully featured client that is playing every media type (i.e. [Buffalo LinkTheater? PC-P3LWG/DVD]). ControlPoint The ControlPoint connects MediaServer and MediaRenderer. It usually has a graphical interface that shows all available servers in a tree structure and when the user selects one the content of this server is displayed. Now all the content can be browsed, typically by file name, artist, song name, etc. If a file was chosen and more than one MediaRenderer is available the user has to choose where to play the file. After making the choice the URL of the chosen file is sent to the chosen renderer who in turn requests the actual file using this URL. When the URL is sent to the renderer it does not automatically start to play. The ControlPoint initiates the playback using a control command. As said before in the MediaRenderer section, the user can control all common parameters like volume, brightness or colour temperature using the interface of the ControlPoint. ControlPoint software without an attached renderer is pretty rare. The only two I know, are Intel AV Media Controller (see page 16) and Cidero MediaController? (see page 16). These two are only ControlPoints without the ability to render any content. An interesting use case is the MediaStreamer? for the Nokia N800. It is a full featured ControlPoint with an internal renderer. While other combined devices can just play the content on the integrated renderer, MediaStreamer? allows the user to control another renderer that is playing some music track while listening to the next track using the internal renderer. -- pcourtney Infrant ReadyNAS 1000S Sparc CPU 512mb and SBS 7.6.1 SBS Remote Control via an iPad2 and Logitech app Squeezebox Duet Receivers WiFi Connected x 3 Musical Fidelity X-CAN v2 Headphone Amps x 3 ------------------------------------------------------------------------ pcourtney's Profile: http://forums.slimdevices.com/member.php?userid=49217 View this thread: http://forums.slimdevices.com/showthread.php?t=83939 _______________________________________________ beta mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/beta
