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

usb 2-1.6: dvb_usb_v2: found a 'Realtek RTL2832U reference design' in warm state
usbcore: registered new interface driver dvb_usb_rtl28xxu
usb 2-1.6: dvb_usb_v2: will pass the complete MPEG2 transport stream to the software demuxer
DVB: registering new adapter (Realtek RTL2832U reference design)
usb 2-1.6: DVB: registering adapter 0 frontend 0 (Realtek RTL2832 (DVB-T))...
r820t 9-001a: creating new instance
r820t 9-001a: Rafael Micro r820t successfully identified
Registered IR keymap rc-empty
input: Realtek RTL2832U reference design as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.6/rc/rc1/input20

rc rc1: lirc_dev: driver ir-lirc-codec (dvb_usb_rtl28xxu) registered at minor = 0
usb 2-1.6: dvb_usb_v2: schedule remote query interval to 400 msecs
usb 2-1.6: dvb_usb_v2: 'Realtek RTL2832U reference design' successfully initialized and connected

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:
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)
