Generation of a transport stream for DVB and realisation of a HF-modulated DVB-signal

120 | P a g e

A: Part A represents the Transport Stream Info. It will display the following information if it’s available in

the stream:

- Transport Stream ID.

- Each program detected into the stream.

- Program name and total bitrate of the program.

B: This window represents the PID info. It will display the following information if it is available in the

stream:

- Each PID and its association with a program number.

- The bitrate of the PID.

- PCR presence.

- Whether or not the stream is scrambled.

C: This window represents the File info. It will display file’s information:

- File name.

- File size in bytes.

- Number of full packets in the file.

- Packet Size.

- Estimated Rate for the TS and the Line.

- The number of the trailing bytes and not part of a full MPEG TS packet

NOTE: The line rate includes Reed-Solomon 16 bytes extra information, if present.

D: ASI rate control. Here we’ll have the chance to change some settings from the output rate of the

playback.

E: Here the user can select the part of the RF spectrum where the modulated signal is going to be sent.

Enter the cannel to access the center frequency of the digital modulated signal.

F: In this section the type of modulation and settings such as bandwidth, forward error correction will

dictate the symbol rate and therefore the data rate throughput that needs to be sent to the modulator.

As with most modulators the data rate needs to be very close to the theoretical data rate in order to

function properly.
