9.5 Deleting a satellite position

To delete a satellite position from the satellite list, proceed as follows:

>Use the arrow keys to mark the field Current satellite list.

>Press OK to open the current satellite list.

>Use the arrow keys up/down to select the satellite you wish to delete.

>Confirm by pressing OK.

>Use the arrow keys to mark Delete sat.

>To delete the satellite press OK and confirm the message displayed by pressing OK again.

9.6 Reference position

When installing the external installation, the motor must be in the reference position (0°). You can thus return the motor to this position (0°) at any time using the function “Go to reference position”.

>Press the red function key Ref.pos to turn the antenna automatically to its reference position.

10 Technical terms

Antenna cable:

Connecting cable between the modulator of the satellite receiver and the antenna input of the television set, used as an alternative if no SCART socket is available.

AV: see SCART

Co-axial cable:

Connection cable between LNC and satellite receiver,used to transmit the signals received, and to supply current to the LNC.

Data compression/MPEG1/MPEG2:

The volume of data involved in transmitting the current television standard (625 lines, and a picture frequency of 50 Hz results in a figure of 216 MBit/s of digital data.

This would require bandwidths that can currently not provided, whet- her by satellites nor by terrestrial systems. For this reason, the total volume of data transmitted is reduced by means of a compression algorithm. For Europe, MPEG-2 has been accepted as the internatio- nal standard for data compression. MPEG-2 is an expanded version of MPEG-1.

DiSEqC:

Digital Satellite Equipment Control: A digital switching signal used to control DiSEqC-compatible components of the external installation via the antenna cable. An example of an installation consisting of DiSEqC components can be seen in (Fig. 10-1).
