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

channels are. Using the multiplexing technique it is possible to include into one transport

stream several programs depending on the sizes and the quality of the image. These programs

inside the stream are called channels. Each channel represents one stream and all the streams

multiplexed together are called as one, multiplexed transport stream. Multiplexed transport

streams are capable of carrying both video and sound in the same channel and also in separate

channels. The user who receives the stream has the ability, by using the right equipment (e.g.

television), to choose the channel that they want to watch or the radio station that they want

to listen.

9.2 Visiosat AVT100:

Before the correction of the exercises a set-up in the laboratory preceded so that the

equipment could be fully functioning and the results could be realistic.

The first thing that had to be done was to install an antenna. The roof antenna was not

available so the laboratory TV network couldn’t function. We used an indoor antenna

connected to the laboratory’s network and run some tests to get the best available position and

orientation for the antenna to receive the maximum possible signal power. The antenna was a

“Visiosat AVT100” indoor amplified antenna. It’s a discreet indoor antenna that allows the

reception of analog and digital channels.
