Advanced unclear QAM Settings for Beyond TV 4.9 and above
Depending on your cable source, tuning unclear QAM can vary from location to location. Some issues that may cause this flucuation can be a weak signal, an over amplified signal, splitters, and/or bad cables. In order to fight some of these issues, we have included several settings that may assistance you in tuning unclear QAM.
These settings are located in the Settings.xml file located in :
These settings are currently set to the value that has proven to be the most useful to tune unclear QAM. In order to make these changes, please make sure Beyond TV is completely shut down. Right click on the Beyond TV icon in the system tray by the clock and then choose Exit. Once Beyond TV is completely shut down, open the Settings.xml file with an XML Editor and then modify these settings.
- Windows XP - c:\Documents and Settings\All Users\Application Data\SnapStream\Beyond TV\
- Windows Vista - c:\ProgramData\SnapStream\Beyond TV\
- 'AllowHRCIRCComboScan' - default '0' ; option is '1'
"HRC" is harmonically related carriers. "IRC" is incrementally related carriers. These are methods that cable companies use to modulate the video signal to improve quality of transmission. During a Beyond TV QAM Scan, when the type used by your provider has been determined, the opposing type is no longer scanned for. If a cable provider broadcasts QAM using both methods (very rare) you may override this setting to account for this possibility. This will increase scan duration greatly.
- 'AllowQAMScrambleCheck' - default '1' ; option is '0'
When this setting is enabled, Beyond TV will look for the scrambled flag of individual packets on a stream to determine whether the stream is encrypted and the flag in the PMT. When it is disabled, Beyond TV will only use the flag in the PMT for the stream to determine if a stream is encrypted.
- 'QAMSleepTime' - default '2' ; option is '1-20'
This refers to the numbers of seconds spent looking at each channel before the scanner moves on to the next channel. 2 seconds is default, but some channels in some areas may need more time.
- 'EnableHDHomeRunSnip' - default '1' ; option is '0'
This setting will disable Beyond TV's real-time StreamSnip operation that will by default, throw out all sub channels in the same stream. This only affects use of an HDHomeRun. This may be disabled if there are problems finding or mapping channels when using native QAM mode in the HDHomeRun.
