Userspace apps thinks ISDB is DVB-T, so they all work. The only think that doesn't work, via the emulation code, is radio broadcast. There are some DVBv5 properties that need to be filled for it: #define DTV_ISDBT_SOUND_BROADCASTING 19 #define DTV_ISDBT_SB_SUBCHANNEL_ID 20 #define DTV_ISDBT_SB_SEGMENT_IDX 21 #define DTV_ISDBT_SB_SEGMENT_COUNT 22 As there's no equivalent of those on DVB-T, and those parameters aren't automatically detected by the (current) frontendds. So, only a program prepared to use them would work. Also, not all ISDB drivers are prepared to work with those properties. I never tested radio broadcast, as there aren't any such stations in Brazil, so I can't tell if it works or not. > I know this is a different topic, but would you know if mplayer is supporting ISDB-TB? AFAIKT, mplayer doesn't support DVBv5 API, but, provided that you feed it with a proper channels.conf file under ~/.mplayer, it works fine. > While vlc and xine/kaffeine work, gstreamer and mplayer are still not working with ISDB-TB for me ...
