# Filter options tab

The Filter options tab (Pic 50) provides adjustment fields for basic parameters of the Unicast, Broadcast and Multicast filters. All changes will become effective by pressing the Apply button (Pic 1).

### Unicast PID

The Unicast PID is a default value for the PID with which the Unicast (Internet) data is sent. You get the PID from your service provider. The Unicast filter is automatically added to the filters list (Filters tab) and activated if the field contains a valid PID (16 ... 8190). In the Unicast (internet) filter settings (Pic 14 rhs) frame, choose an option to determine on which MAC address the filter will be set.

### Broadcast PID

The Broadcast PID is a default value for the PID with which the Broadcast data is sent. You get the PID from your service provider. The Broadcast filter is automatically added to the filters list (Filters tab) and activated if the field contains a valid PID (16 ... 8190). Leave the field empty if your service provider does not send Broadcast data.

### Multicast PID

If a provider transfers all multicast data services with the same PID it should be entered here. This enables the
to automatically set the Multicast filters with the correct PID. Otherwise the input field should remain empty (0).

### Set Multicast PIDs automatically

This checkbox selects a new method for PID determination. By this method, the PID doesn't have to be equal for every multicast data stream and it doesn't have to be set manually. If the checkbox is activated and a Multicast filter is requested, the PID is calculated from the Multicast IP address, a filter will be added to the filters list and it will be activated. The automatic determination of the PIDs for Multicast data services should only be used with service providers which are using this method too ("Recommendation for automatic channel setup using IP multicast group addresses").

###
Use MAC address of the DVB card

If this option is selected, the filter for the Unicast (Internet) data is set with MAC address of the
. This is the method currently used by most data service providers to address Unicast data. This method works only if the data service provider knows the MAC address of the
or if the MAC address is transmitted to the data service provider during the login procedure.

### Calculate MAC address from the IP address of the dialup connection

If this option is selected, the MAC address of the filter for the Unicast (Internet) data is determined from the IP address of the dialup (PPP) connection. Choose this option if you are connected to the Internet by modem or similar means and your data service provider uses this method for MAC address calculation ("Seamless integration of IP-unicast transport using dynamic IP address to MAC address mapping"). The filter is automatically adjusted in case of a change to the dialup connection's IP address.

### Calculate MAC address from the IP address of the following network card

If this option is selected, the MAC address of the filter for the Unicast (Internet) data is determined from the IP address of the chosen network card. Choose this option if you are connected to the Internet by a network card and your data service provider uses this method for MAC address calculation ("Seamless integration of IP-unicast transport using dynamic IP address to MAC address mapping"). Select the network card your computer is connected with to the Internet.
