AutoUSCableMapFiltered: used for legacy applications that only support the Cable channel

map. The HDHomeRun driver will look up the requested frequency and compare with the channel

configuration recorded by HDHomeRun Setup. The requested frequency is converted to a HRC or

IRC frequency as needed.

If the requested frequency is known not to contain unencrypted digital video then the channel will

be set to “none”. This will result in a zero signal strength and speed up the channel scan process.

RemapFrequency: used for legacy applications that support DVB-T but not DVB-C. The

HDHomeRun driver will look up the requested OTA frequency in the lineup file (RemapTrigger

field). If a match is found it will tune the actual frequency specified in the lineup file.

RemapProgram: used for legacy applications that support ATSC but not ClearQAM. The

HDHomeRun driver will look up the requested OTA frequency in the lineup file (RemapTrigger

field). If a match is found it will tune the frequency+program specified in the lineup file. When

operating in this mode the HDHomeRun will generate the PAT, PMT, and VCT information needed

to work with ATSC only applications. When using this mode only 68 channels can be used as there

are 68 OTA frequencies (channels 2 to 69).

Channel identification:

US Digital Cable providers typically do not sent a VCT with the stream. In cases where a VCT is

included in the stream this information often incorrect.

Silicondust maintains a lineup server that tracks unencrypted digital cable channels to match with

guide data. Silicondust provides access to this information via a web API – see following Lineup

Server chapter.

Driver configuration:

The user specifies the application they intend to use with the HDHomeRun when the run

HDHomeRun Setup. This selection sets a number of registry options to adjust the driver behavior

to suit the specified application.

For development the Application can be set to “Other: Registry”. This tells HDHomeRun Setup not

to overwrite the registry options, thus allowing the options to be set manually.

For production please contact Silicondust to have your application added to the list of user-

selectable applications in HDHomeRun Setup.

Registry:

The BDA driver configuration is per tuner, stored in:

HKEY_LOCAL_MACHINE\SOFTWARE\Silicondust\HDHomeRun\Tuners\<device id>-<tuner index>

Values are case sensitive.

Source Name of the source. Should be set to “Digital Antenna”, “Digital Cable”, or “Disabled”

unless there are multiple directional antennas or multiple cable systems.
