# Filters tab

The Filters tab (Pic 40) is used to configure the filters and to display the filter parameters. Filter configuration is possible using the Add, Edit and Delete buttons.

### PID (Packet Identifier)

The PID separates an individual packet stream from the DVB signal. This allows the reception of the desired radiated DVB data service from the service provider.

### Set

This displays whether a filter is set (in use). UC = Unicast filters; BC = Broadcast filters; MC = Multicast filters. The filter can only be set by the
if the use is permitted (shown in the use field) and a valid PID (PID field) has been entered.

### MAC (Media Access Control)

The MAC address is a way of continuing the differentiation of the package stream selected on the basis of the PID. Thus, only the packet with the correct address reaches the Windows network layers. With multicast DVB data services the MAC address can be calculated from the IP address. In this case, the input of the IP address is sufficient.

### IP (Internet Protocol)

The IP address is for setting the allocation of filters to Client applications and the address input with multicast filters.

### Length

Number of bytes in the MAC address to be entered into the filter (normally 6, with 0 only on the PID to be filtered).

### use

This displays whether a filter is to be used.

## Filter settings

### Adding a filter

The dialog box Filter settings (Pic 41) opens by clicking Add (Pic 40) or by double clicking on a free place in the filter list. The input fields contain default values for a new filter. Modify the desired parameters and click OK to add this filter to the filter list.

### Changing a filter

Modification of an existing filter setting can be achieved by either clicking Edit (Pic 40) or double clicking on the filter to be changed in the filter list. The Filter settings box (Pic 42) is generated whereby the parameters can be modified. Click OK to activate these modifications or Cancel to reject the changes.

### Removing a filter

A selected filter can be removed by clicking on the Remove button (Pic 40) in the Filters tab.

# Filter / Filter options tab

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

## PIDs

### PID

Use this to add PID's to the PID-List.

### PID-Liste

This list contains several PID's that can be used for sending Data. If you don't know them, ask your Provider. The value range for valid PID's lays between 16 an 8190.

### Hexadecimal PID-Representation

The PID's will be shown in hexadecimal format.

### 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.
