Channel Sync

[spidrmetal]

Hello Everyone:

So I'm using the Home Electroncis Ira/Tira 2 IR transceiver with Girder to change channels on my cable box. For whattever reason when I press the up or down channell buttons, my tv software (Beyond TV from snapstream), does not stay in sync with the current channel on the receiver.

For Example I press Channel Up 5 times but my Direct TV receiver only goes up 4 channels.

Now I'm sure if I play around long enough with the ms delay, etc. I might be able to get it so that in most situations it doesn't do this, but I thought of another idea, I'm just not sure how to implement it in Girder.

Lets say I press Channel Up 5 times. Beyond TV will automatically go to the correct channel but its the receiver that will be off. So instead of firing 5 chanell up events from Girder, is there a way that I can just get the current channel, and then set the current chanell to +=5??

i.e. dont't fire 5 (or less) channel up events, but rather add 5 to a number (which is the current channel), and then have girder fire a channel change event to that channel?

So instead of doing this:

200 [up] 201 [up] 203 [up] 204 [up] 205

Do this:

Current Channel = 200
[up] [up] [up] [up] [up] = 5
Set Channel to 205

Thanx

Sean,

IF you are doing up/down sequences, you will always have problems keeping everything in sync.

You could have Girder track the current channel in a variable and then send the complete channel everytime to the cable box.

OR, if you STB has a serial port, then that is the best way to control it.

No no serial port. . . I know that sux. . .

There's a phone jack and another data port, but that's it. Its a generic D10 DirectTV receiver.

Can you give me an example of how I would send the complete channel from girder to the sattelite box evertime?

Thanx. .

I think there are some Girder files in the BeyondTV forum that show you how to do this.

Have you had a look there?

According to a thread (http://forums.snapstream.com/vb/showthread.php?t=18418) at the snapstream forum, the D10 is an RCA DRD435RH receiver and one of the ports on the back IS for low speed (serial) data communication. Are none of your ports marked that way?

[spidrmetal]

yeah, one of my ports is marked that way but I didn't know that's what its for. . .

soo. . . can you point me to that thread??

Also, so from what it sounds like I could buy a serial controller from snapstream to solve this problem. . . .

Possibly. Please try searching their forum for info.

I placed the link in my post (click the part that says "a thread"); but, just in case that doesn't work:

EDIT: I don't know the ramifications of using snapstream with this.
