Intel® Digital Set Top Box Display Driver User’s Guide for Microsoft* Windows* CE 5.0 4.1.7 Direct3D Mobile Options Direct 3D Mobile is supported on the 830 and 854. [HKEY_LOCAL_MACHINE\System\D3DM\Drivers] RemoteHook This is set to “ddi_iceg” to inform GWES which driver to request Direct3D Mobile support from. Leaving this blank will disable Direct3D Mobile in the operating system. [HKEY_LOCAL_MACHINE\Drivers\Display\Intel] Enable3D This setting enables or disables 3D support in the display driver. 0 disables support, 1 enables support. If it is enabled, a valid Direct3D Mobile needs to be loaded. See 3DModule below. SharedMemHeapSize This key is used to set the size (in bytes) of the shared system memory heap to be allocated at driver startup. This setting defaults to 1MB if not specified otherwise. SharedMemHeapMaxAllocSize This key is used to set the maximum size (in bytes) to allocate from the shared system memory heap. Any requests larger than this will have a dedicated memory allocation created for them instead of coming from the common heap. This setting defaults to 256KB if not specified otherwise. [HKEY_LOCAL_MACHINE\Drivers\Display\Intel\3D] 3DModule This setting determines which Direct3D Mobile module gets loaded. Leaving this setting blank will load no Direct3D Mobile module. Intel® Digital Set Top Box Display Driver 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. 4.2.2 Conexant Port Driver Attributes See the configuration file video.reg for information on the Conexant port driver attributes. Look for details in the section entitled “Conexant CX25873/CX25892 port attributes”. Contact Conexant for more information on the Conexant port driver. Intel® Digital Set Top Box Display Driver User’s Guide for Microsoft* Windows* CE 5.0 4.2.2.1 DAC setting with different TV Output Type on HH2 Currently there is a new video card named “Hominy Hill2” that uses the CX25899 as the TV encoder. There are four analog outputs on that card, which can be configured to different signals in order to adapt to the different TV Output Types. In video.reg, there are 4 parameters for analog output’s setting, “DACA, DACB, DACC, DACD”. So if the parameter “TV Output” is set to 1 (Composite + S-Video), 2 (Composite) and 3 (S-Video), the DACs need to be set to: “DACA”=dword:4 “DACB”=dword:3 “DACC”=dword:2 “DACD”=dword:1 Else if the parameter “TV Output” is set to 4 (Component) and 6 (Composite+RGB), the DACs need to be set to: “DACA”=dword:3 “DACB”=dword:1 “DACC”=dword:2 “DACD”=dword:4 Option 6 of “TV Output” is for a special TV connector named “SCART I” which is very popular in European. This option is only available for the “Hominy Hill2” now since it can output four analog video signals at the same time. The default DAC setting in video.reg is for “Lost Creek”(CX25892) when you select the "PortDrivers" as "cx873", so please modify this setting if the video card is changed among “Miller Creek”, “Lost Creek” and “Hominy Hill2”. 4.2.3 Focus Port Driver Attributes See the configuration file video.reg for information on the Focus port driver attributes. Look for details in the section entitled “Focus FS454 port attributes”. Contact Focus for more information on the Focus port driver. 4.2.4 Silicon Image Port Driver Attributes See the configuration file video.reg for information on the Silicon Image port driver attributes. Look for details in the section entitled “Silicon Image 9030 port attributes”.
