Singapore DVB-T

LinuxTV: this stuff is all working on a noname DVB-T stick with RTL2832U and R820T tuner.
For Fedora kernels you have to use the LinuxTV media_build backport drivers to support the R820T tuner

This will be history when Singapore switches to DVB-T2 at the end of 2013.

But for the record…

    For services at 610MHz:

  • Digital 8
  • Digital 5
  • Digital CNA
  • MediaCorp HD5

The ‘MediaCorp HD5’ service uses H.264 AVC and this is misidentified by mplayer as a MPEG2TS. Found a workaround here: https://bbs.archlinux.org/viewtopic.php?id=159744
I.e.,
mplayer dvb://'MediaCorp HD5' -demuxer lavf

There is reference to an old channel at 538MHz, but this is unused now.

Initial DVB-T scan file:

# T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy
T 610000000 8MHz 2/3 NONE QAM64 8k 1/8 NONE

    Attached (as PDF) are an scandvb initial scan file and tzap channels file. The tzap file works with mplayer & vlc:

  • sg-MediaCorp (initial scan file)
  • channels (tzap file, suitable for mplayer,vlc etc)
