said by hitachi369:Only up/down with no reference level means absolutely nothing. Not to mention that the receiver may or may not catch signals intended for the TV and has no way of telling whether the TV has actually received them or not.
It could pick up the IR signals from the remote either way.
Re: HOW??? No, it's not the "IR Blaster" kind of LED. It only blinks when you adjust volume using the TiVo-specific remote. For example, you hold the "VOL -" button for 3 seconds, when you let go it blinks. You hit mute, it blinks. It does not blink when you adjust the volume using the AV receiver's remote or a universal remote. It does not blink when receiving "random IR", only when it processes a valid command.
The remote specifically sends a command to the box letting it know you've adjusted the volume. It is not doing any volume adjustment on the box itself, this is only for tracking purposes. Additionally, as I already noted, it also sends this information back to the home server, in real time. Any command you send the unit is tracked over the internet in real time. Pause a TV show? Data sent. Rewind a TV show? Data sent. Skip a commercial? Data sent.
If you know anyone who knows how to use a packet sniffer and has a TiVo (not sure about other DVRs), it really is astonishing how much live information is transmitted back to the home office.
If you use a universal or stock remote to adjust volume, they will not be able to track it. Additionally, they don't want to know "how loud" you're listening to the programs. They want to know what times you raise or lower the volume from whatever the baseline level you are listening to the program at. With enough of this kind of data in aggregate, it can be very valuable to advertisers.
said by clone:I've just made a test and recorded the output of the remote (IR blasts) on the oscilloscope and compared to the remote of the AV receiver.
As I noted above, when using the remote that comes with the DVR, you will program it to control your audio device (TV or Receiver, whatever), then it will also send an extra command to the box to inform it you adjusted the volume.
Steps, etc. has no bearing. They only want to know at what times you raise, lower, or mute the sound. By how much, etc. is not important.
Let's put it this way: NO, IT DOESN'T SEND ANY DATA IT SHOULDN'T.
said by clone:No, the output of the ATT remote. Remember the thread is about ATT, right?
You compared the output of the TiVo Premiere Series4 XL remote with a stock remote from an AV receiver and you didn't find any difference?
I don't believe for a second that you did that, or you would know you are incorrect.
| || Actually it does. Over time, a relative level is established and that is perfectly fine to determine when programming might be objectionable, salacious, interesting, too quiet or whatever. I doubt they really care that you're listening to your TV at 23 db. They do care that you cranked up the volume to pay attention to the person singing country music on American Idol.|
Well, that's not entirely true. Hearing aid companies might want to know the exact level, but I doubt anyone else cares. The rest of the data, when coupled with everything else collected, helps paint a clearer picture.
With that said, any DVR that does this is out the door.

But anyway, in regards to ATT this is not the case since no info is being sent to the box.
