Dynamic Video Quality Enhancement

Enabling this feature allows the driver to automatically set the best quality setting for each TV channel.
It does this in 2 ways:

• When first enabled, the driver will run a scan on the current active channel. Anytime a channel change occurs, the driver will check if that channel has already been scanned. If it has not, a scan will be initiated and the Sens value (Quality setting) will be updated.
• If a channel has already been scanned, the driver will monitor the noise on that channel and update the Sens setting if the noise level goes above a preset threshold.

Note: The scan will last for approximately 10 seconds. During this time the picture and sound might get distorted.

Note: If the channel is changed before the scan completes, the scan will stop and the default Sens value (4) will still apply for the current channel.

Note: This only affects analog cable TV signals. It has no affect on digital TV signals (ATSC) or analog TV received via an antenna.

Additional Controls

Rescan Channel Threshold

Note: This control is only active if Dynamic Video Quality is enabled.

When Dynamic Video Quality is enabled, this slider can be used to set the noise threshold that will trigger a rescan of that particular channel. If the driver detects that the noise on the channel is above the selected threshold, that channel will be scanned again. The range is 100% to 200%. A lower number will make the rescan happen more often.

Channel Information

This section shows the current channel, Sens level and if the scan is active or not.
Additionally, you can manually override the Sens level but selecting the Set manually for current channel.

Note: The manual override button will fix the Sens level for that channel only. The driver will not continue to monitor the channel based on the Rescan Channel Threshold setting.

Note: Disabling the manual override button will set the Sens level back either the default (4) or to the value determined by the Dynamic Video Quality check.

Reset

This button will reset the Sens based on the following conditions:

• Dynamic Video Quality enabled - Resets all channels back to the default Sens (4) and starts a new scan of the current channel.
• Dynamic Video Quality disabled - Resets all channels back to the default Sens (4).

Note: Selecting the Reset button will erase all current and manual override settings.

Antenna Reception

Dynamic Video Quality is only active when Dell External USB NTSC/ATSC TV Tuner is connected to an analog cable signal. If the Property Page is selected when connected to an analog antenna source, the Property Page will look like this:



Notice that all of the controls are greyed out and not accessible.

Note: The driver will automatically determine if Dell External USB NTSC/ATSC TV Tuner is connected to a cable or antenna source. In order to do this, it is necessary that the system is tuned to any channel greater than CH13 at least once after changing between cable and antenna.
