Can I control a DLNA device (SONY TV) from Linuxmce?

[ladekribs]

I would like to power on/off a Sony TV via the network using DLNA commands, and maybe also select input,control volume etc.

Is it possible?
where can I find the command syntax?

looks like it's time to do some research, buddy.

Stefan,

best place to ask this would be your local Sony representative. But I would not put my hopes to high

[ladekribs]

@Thom,I have been searching for a while with no luck, trying to read the upnp docs, but know too little to understand it

@Posde, thought that maybe some other device used standard UPNP or DLNA commands, like for example the roku soundbridge,or the Sony VPL-HS51 Ethernet?

did you try to control it with the generic control point from gupnp? It has a nice upnp browser..

My understanding is that actual av control over upnp is spotty by device. Different ones come with remote control capability of vary degrees with the newer ones supporting remote initialization of both online media via integrated applications (connected tvs and such) and playback of media from devices such as other upnp servers and media devices. The upnp universe is far from anything resembling coherent at the moment despite the supposed DNLA Alliance. Basically, as others have mentioned, you need to investigate what the target devices capabilities are fully. LinuxMCE can do just about anything, its the devices its talking to and their interfaces being co-operative thats the question.

Hari's recommendation of using a upnp browser is a good idea although its probably best to investigate before you buy.

Hi Stefan

We're very interested in this whole area ie using the more advanced aspects of the UPnP spec to allow all control functions to be handled. The next release of Dianemo will implement UPnP-AV and this enables our Dianemo system to become a UPnP control point and therefore control any UPnP device that supports the standard; See here for more info on what we're upto http://forum.linuxmce.org/index.php?topic=8880.msg60443#msg60443

In principle what you are asking is possible but those controls are not in the UPnP-AV service itself and so it would require the manufacturer to support the extended RenderingControlService. I am not aware of Sony doing that to date. See the snippit of the UPnP AV Architecture:1 docs below for a brief para on this service;

3.2.1. RenderingControlService
This service provides a set of actions that allow the Control Point to control how the Renderer renders a
piece of incoming content. This includes rendering characteristics such as Brightness, Contrast, Volume,
Mute, etc. The Rendering Control service supports multiple, dynamic instances, which allows a Renderer
to “mix together” one or more content items (e.g. a Picture-in-Picture window on a TV or an audio mixer
device). New instances of the service are created by the ConnectionManager::PrepareForConnection()
action. If the ConnectionManager::PrepareForConnection() action is not implemented the default value

See this doc for further information; http://upnp.org/specs/av/UPnP-av-RenderingControl-v1-Service.pdf

The full set of UPnP docs can be downloaded and read at your leisure here; http://upnp.org/sdcps-and-certification/standards/sdcps/

Hope the above is of use to you.

All the best

Thank You all, I will start reading.

Hi All,

Sony support said that for time being such commands (poweron/off) are not supported, but has now been suggested as a good feature.

All HDMI hardware includes the CEC protocol wires. Though few includes all CDC features, and most of them use proprietary ones, I would bet that those that do have CEC functionality support turning device ON and OFF.

So if your TV has HDMI then it has the CEC wires. Sony uses its own version of CEC called BRAVIA Sync.
We just need a few years of hacking it:)

Your right about CEC... but the problem is every manufacturer implements it in a proprietary way and therefore as you say it will take years of trial and error to get any kind of cross vendor support in place. With UPnP's RenderingControlService we are likely to see a lot of manufacturers get on board and they can add it and update in simple over-the-air updates that dont rely on specific hardware.

We expect to see Sony, Panasonic, LG and Philips support the RenderingControlService before the end of the summer this year in pretty much all of their lineups.

All the best

Sounds great, tm, I didn't know about RenderingControlService!

did the manufacturers meet your expectations?

Yes some have - Panasonic and Sony in particular.

Hi, I know this is an old topic, but... Most* Sony TV's (2011+) with network cards can be controlled using the Sony Virtual Remote  (v1.2 is the latest I could find). It uses IRCC (some kind of UPNP or DLNA derivative) to communicate with the TV:

Ircc_Xml\Bravia_default.xml
 <command name="Power" type="ircc" value="AAAAAQAAAAEAAAAVAw==" />
  <command name="Display" type="ircc" value="AAAAAQAAAAEAAAA6Aw==" />
  <command name="VolumeUp" type="ircc" value="AAAAAQAAAAEAAAASAw==" />
  <command name="VolumeDown" type="ircc" value="AAAAAQAAAAEAAAATAw==" />
  <command name="Mute" type="ircc" value="AAAAAQAAAAEAAAAUAw==" />

The virtual remote works fine after it's paired to the tv. I'm just trying make a device template to accommodate it... If anyone can point me in the right direction it would be appreciated
