There are three ways to control a disc or tape player:

1. Selecting a device on the touchpanel main page automatically summons a virtual control panel for that device. Only the most common functions are available.

2. Remote controls are provided and stored in the equipment rack drawer. These are ideal for standing away from the equipment rack. Allow for adequate line-of-site to point the remote at the device.

Audio playback

Volume for all media sources including DVD and VCR is controlled from Program Volume on the touchpanel main page.

Audio

Occasionally, a DVD disc or VHS tape requires a specific audio setting by the player for accurate audio playback. In the event of missing dialogue, music, or other anomalies, try checking the audio settings of the playback device and/or the DVD on screen.

Subtitles, closed-captioning

Both subtitles and closed-captioning (CC) are on-screen text overlays that manifest the dialogue and other sounds of the actual broadcast or film.

DVD subtitles provide language translation where an alternate language audio track in the desired language is unavailable. Closed-captioning is used for the hearing impaired or when the audio is muted.

To turn subtitles on/off, with your disc loaded, navigate to the MENU. If the disc has subtitle options, they should be under a heading called "settings" or "options," etc. depending on how the disc is set up.

Closed-captioning requires a hardware decoder present to generate the text on-screen.

If you have questions about the availability of CC in a certain location, please ask Media Services!


Aspect ratios

The aspect ratio describes what kind of rectangular shape is used to display a video or film.

The ratio itself is a measure of width:height, usually expressed as the simplest pair of numbers that maintains the dimensions. Generally speaking, though, every aspect ratio can be described as being normal or widescreen.

Aspect Ratio

While it is ideal to experience a video/film in its intended aspect ratio, any aspect mismatch, such as with the TV monitor/projector or media formatting, leads to a slight compromise in either size or proportion of the original.

The in-room data projector has a native aspect ratio of 4:3. Use the aspect compensation buttons to manually choose the best adaptation for the current signal that minimizes stretching/squashing artifacts.
