Intel® Digital Set Top Box Display Driver 21
User’s Guide for Microsoft* Windows* CE 5.0
4.2 Port Driver (TV Encoder DLL) Attributes
Port driver (TV Encoder DLL) attributes are used if the display type is either DVO-only or Twin. In that case, the
display driver reads port driver attribute settings from the registry, tests their values, and if they are valid, passes
them to the port driver during initialization. Port driver attributes have Boolean, range, String, or list types. Boolean
attributes values must be 0 or 1. Range attributes must match the minimum, maximum, or an internal value
computed using the step – similar to a “for” loop in C Language “for (valid = min; valid <= max, valid += step)”.
String values are typically read-only. List values must match one of the list entries.
If an attribute name does not match a supported attribute or if an out of range value is used, the display driver will
fail to load and this will result in a GWES exception.
Port driver attributes are set at the following key:
[HKEY_LOCAL_MACHINE\Drivers\Display\Intel\Param\Attr]
4.2.1 Port Driver Attribute Notes
Note: If an attribute name does not match a supported attribute, or if an out of range value is used, the display
driver will fail to load and this will result in a GWES exception.
Note: The port drivers include a TV Format attribute. Please note that changing this attribute at run-time is not
supported in the display driver.
