Is TiVo HDMI CEC Compliant?

> Actually, does anybody have devices that use it at all?

Never seen in myself. I've got some Pioneer equipment that has it's own
interface between the TV and the receiver. When the source on the receiver
is changed it signals the TV to change which input it's using. As in, DVD
from Input 5, PC from PC input, Tivo from Input 6, etc.

The trouble with backchanneling remote control is distributing it. When a
display has multiple inputs how does it decide where to send the remote
signal? Does it just go back to the receiver? Or is it passed along to the
source device? Not as simple a problem as you might expect.

Seems like it would have to be pretty complex. Either there would have
to be standard set of commands, at least for the basic ones, and/or a
device ID and and command table, that both sending and receiving
devices would have to understand. Communicating on a network kind of
like MAC or IP addresses.

Or maybe something else entirely. If I can locate the standard I'll post it.

I see roughly the same behavior between my Phillips DVD player and my
Sony TV, whose only connection is an HDMI cable. If you turn the DVD
player on or insert a disk, the TV automagically selectrs the DVD
player as its input. That's it. Actually, not all that convenient.
I usually have something being watched on the TiVo when I insert the
disk, since I'm doing that "in advance" to be able to skip the startup
screens & various warning messagesw about not copying the disk, so
that when the current TiVo program is over, I can almost immediately
start the movie on the disk. However, with the DVD player changing
the input to itself, I have to then add the extra steps of resetting
the input back to the TiVo and then skipping back to replay the few
seconds that were missed.

Note, if the TV is off and I turn the DVD player on, it turns the TV
on and sets the input also. That does seem convenient.

However, like most user interface things, one size doesn't fit all.

However, the HD TiVo (or S3, I can't recall which, the cheaper one)
doesn't do either. On the other hand, I never turn it off. But
hitting the TiVo or Live TV button doesn't cause the TV to switch to
the TiVo even though the TiVo is connected to the TV via an HDMI
cable. If it were to follow the protocol I would expect that to
happen.

Note, on the DVD player, the protocol is advertised as an energy
saving (green) feature because things go into low power/standy mode if
you aren't actively using them. If you pause (or stop) the DVD and let
it sit for long enough (5 mins?), it goes into standby (and I don't
recall whether it takes the TV with it or not).

Same here - On my "off" BD box, I press the "Open/Close" button, and
the TV takes the still-dark input while the idiot BD won't open the
friggin' tray until its looong boot sequence is complete!

Very stupid bass-ackwards design there. "It's not a bug, it's a
feature!"

No, he's right. Some new disc players take a gawd awful long time just to
eject the disc.
