DVB-T2 decoding

Post by dobroslav » Tue Mar 21, 2017 3:08 pm

Hi all,

After reading DVB-T2 specification and "implementation guidelines" (which is quite large) I still don't understand how data frames are interleaved over subcarriers. In my city there are two DVB-T2 channels with 8Mhz bandwidth, which is quite typical I think. Is it possible to decode something useful (service information, actual video data) using 2.8Mhz width of RTL-SDR, or every physical-level pipe is interleaved over whole 8MHz, so SDR capable of 8MHz sampling rate is required?

Hi,

"dvbsnoop is a DVB / MPEG stream analyzer program, which enables you to watch (live) stream information in human readable form."

"To use the realtime sniffing mode you need a dvb card installed into your system. To analyze a stream file, you just need Linux"

- a DVB card
- Linux DVB API version 1 or 3 installed (see http://www.linuxtv.org)
or
- a Linux based set top box (using DVB API version 1 or 3)
(e.g. 'dbox2' or 'dreambox')
