Tuning Modes:
Auto Tuning
From the select frequencies, the receiver will automatically search for all other frequencies within the
tuning range and downloads them automatically into the receiver. Once the channels have been
downloaded, all the TV and Radio channels will be displayed separately allowing the user to inspect
them and decide whether they are to be stored or aborted. This option is not available in Manual tuning
mode (F1).
Network and Bouquet Tuning
Within a digital broadcast transmission, many other network frequencies are provided to guide the
receiver to tune to other Networks. Network tuning enables the receiver to download other channels
from the same network. Use Bouquet tuning you only want to download channels from one channel
frequency group. Bouquet Tuning is used when only the channels from the desired frequency are to be
downloaded.
PID tuning
Apart from the usual channel parameters (Frequency,
Symbol Rate, Polarity and FEC value), the broadcaster
must include additional information (known as Packet
Identifiers or PIDs) in their transmission to allow auto-
tuning to work properly.
In “PID Tuning” you are required to enter the channel
name and three other parameters: Video PID, Audio
PID, PCR PID and Text PID (optional). These values
can either be in Decimal (ranging from 0 to 9) or Hexadecimal (ranging from 0 to 9 and A to F for each
digit).
After selecting from the Preset List, or Manually entering the basic channel parameters (Frequency,
Symbol Rate, Polarity and FEC value), move the cursor to highlight the Manual button and press OK to
start tuning.
Edit the Channel details by following the steps below:-
1. Use the UP, DOWN, LEFT/RIGHT keys, to move the cursor from one field to another.
2. Use the LEFT/RIGHT, F1 and F2 keys to enter the channel name.
3. Select the channel type whether it is a TV channel or a Radio channel.
4. Decide whether you would like to enter the PIDs in decimal or hexadecimal form.
5. Use the F1/ F2 and 0-9 keys to enter the PID values.
6. When you have finished and are ready to store and display that channel, press OK.
Note:
In order for manual tuning to be successful, the PCR PID must be entered. In many cases the PCR
PID is not published. Fortunately, in nearly all cases the PCR is the same as the Video PID or the
Audio PID or 8190 in decimal or 1FFE in hexadecimal.
The Teletext PID is optional and can be ignored when the value is unknown.
