Mapping CVBS or SVHS to real channel? Possible? (1 Viewer)

[falkyre]

Ok,

here's the deal..I don't have your normal setup and without some major home reno, I probably will never have it. I am running digital cable that runs over existing coax from the Set Top box. I have all of three real TV channels on the coax (4, 8 and 11) but I have digital TV piped through those 3 channels. My Set Top box is in my Computer Office not even remotely close to my TV.

I want to sse MP as the main TV/recording system....This is working except for the fact that I can't change channels from the EPG. I can't run RCA cables to my HTPC, it has to be the coax. I am tuned to channel 4 on all EPG channels. I can "change" channels using girder network client to send to a girder running on my main system and then use USBUIRT to change the channels on the STB. What I haven't been able to figure out is how to change channels in the EPG. The only remotely clse thing that exists is that if I map to external channels, I could do it by launching the girder internet client using the MPExtCmd plugin. However, if I use this it is expecting that the input is running on my Svideo or composite and I have nothing running on those. So my question after this long winded post is....

:?:

Can I fake out the external channel changing somehiow such that I am still "tuned" to channel 4 but send a command everytime a channel is changed?

:?:

This is my last piece to getting the HTPC as my main TV device. MP is performing way beyond my expectations...this is the last piece.

Thanks for your upcoming help!

Possible Solution?

Well I think I figured it out...at least it's working the way I want to.

Here's what I ended up doing...

• 
  1) Set all channels to be external
  2) DO NOT select the input (leave the box blank)
  3) Make sure that your channel is set to the channel you want to change to
  4) Save the channel edit
  5) Once done, take a look at your TV Channels. They should be listed like 0/2, 0/3 etc
  6) Using the SQLLite database explorer in the docs directory, modify the channels table in the TVDatabase.db3 such that they look like: 4/2, 4/3 etc.

Now the problem with doing it like this is that I had to go directly into the database to do this and it is possible that this could cause problems in the future build. I haven't had a chance to look at the code for the channel changing piece but I might end up doing that (once I finish the plugin I've started). Anyways, now when I got into the EPG and select a channel, a message gets sent via the girder ieventc.exe to my girder "server" system which I fireoff some USBUIRT codes and change my channel...

Cool

Hi Falkyre,

I have a similar setup to you except I'm in the UK. I have already asked about changing channels on the STB when it is viewed through coax (see my thread - https://forum.team-mediaportal.com/viewtopic.php?t=1379)

I will try your solution of editing the database with the SQLLite tool, if I can work out the syntax...

I've downloaded the source code from SVN and I'm currently trying to locate the code for setting the channel numbers, for internal tuners and external STBs.

If / when I find anything, I'll let you know.

Regards, Ian.
