4.3.3.4. Pre-Filter Type & Max Bitrate
These two items are used to reduce the bandwidth of the incoming signal before encoding, thus improving
video quality – used especially for low value Bit-Rates.
Pre-Filter Type (PFT): There are four options available. The number inside the brackets indicates the
typical target display maximum pixels per line.
Filter 1 reduces the bandwidth of the input signal the most, and Filter 4 reduces the
bandwidth the least.
Pre-Filter Max Bit-Rate (PFMBR): This is used as a threshold value to enable the Pre-Filter Type. The
Pre-Filter is only enabled when the actual 'Bit-Rate' falls below this threshold value.
For example, set the PFMBR to '2 Mbps', and PFT to 'Filter 2 (480)'.
If the Bit-Rate is set to '3 Mbs', the Pre-Filter will be disabled; however, if the
Bit-Rate is set to '1 Mbps' then the Pre-Filter will be enabled.

4.3.4. Set to Default Option

Selecting the Set to Default button will enable the user to set the encoder properties back to the factory
defaults.

4.3.5. SLKE Reset Option

Selecting the SLKE Reset button will enable the user to "soft reboot" the 7700DA4-SLKE.
