Generation of a transport stream for DVB and realisation of a HF-modulated DVB-signal
27 | P a g e
After a couple of openings/closings of the TSReader software I noticed that when we
need to access the “input source select” table when opening the program it doesn’t
always work with “Ctrl + click”. It needs “Ctrl + Enter” from the keyboard.
When you want to open a file at the TSReader you have to be careful to select “all files”
from the dropdown box. Otherwise you may be unable to see the file that you want to
open because you have not selected this kind of file to be shown.
Next remark was during the play of the video “61.mpg”. The English subtitles were not
working. This was because the channel didn’t transmit any. It was transmitted only with
Spanish subtitles.
The 12
th
question of the exercise was:
“In which frequency does TV3HD broadcast? Which is its network name? Where can you find all
these information?
We can find it on the NIT. It broadcasts on 658MHz and the network name is “TELEVISIO DE
CATALUNYA”.”
The question was a bit confusing and misleading during the experiment so with a slide change it
guides you to the right spot. The question and the answer after the change is:
In what frequency does TV3HD broadcasts? Which is the provider’s name? Where can you find
all these information?
It broadcasts on 658MHz and the provider’s name is “TELEVISIO DE CATALUNYA”. We can find
the information on the NIT.
At question 14 it says:
Try to watch the channel “AXN”. Why it’s not possible?
Because it is a pay-tv channel and it is scrambled.
There are not any indications that the channel is a pay-tv. We cannot come to this conclusion
by the data that we get from the TSReader. We can assume it but it can be a private channel or
a private broadcast that we are not allowed to access.
So, there was a remark added to the answer and it became:
Try to watch the channel “AXN”. Why it is not possible?
