| Discrete power commands explained |
|
Typically, devices such as DVD players, TVs, stereo components, etc have a power
toggle button on their remote control. Under most circumstances this is acceptable. If
the unit it off, and you press the power button then the unit is powered on and vice-
versa. However, when used with a smart state remote control (such as a Harmony) devices
behave best if they understand discrete power commands. That is rather than
understanding only a toggle command they can distinguish between the discrete (and explicit)
power on and power off IR commands. Although many remote controls do not have 2 power buttons the corresponding component sometimes can understand the discrete power commands in addition to the toggle. If you use a remote control that keeps track of the state of components, it's important for them to understand discrete power commands because if the remote control thinks a component is off when it's true state is on, then when the smart remote control turns on the component it will be turned off, which is undesirable. This is most important in devices that are often powered on independently of the remote control such as any device that requires the insertion of media (eg. DVD and CD players). For instance, if the DVD player is off and the remote control thinks it's off and then a person presses the eject button to load a movie, the player is now on. If the person then presses the "watch movie" (or equivalent macro) button on their remote control the unit would likely be powered off since it believes the unit is still off despite the user manually powering it on. |
The Oppo DV-971HD delivers incredible visual playback quality via DVI or component output and can flawlessly upconvert the 480p DVD format standard to 720p and 1080i. If you have a newer 1080p capable TV then you should take a look at Oppo's DV-981HD DVD player (which also boasts HDMI output rather than DVI). In addition, the DV-971HD supports digital audio ouput for 5.1 playback. The DV-971HD can play the following media formats:
| DVD Video | DVD Audio |
| DivX | XviD |
| Audio CD | HDCD |
| WMA | DVD+R/RW |
| DVD-R/RW | CD-R/RW |
