Support for Brazilian television

Linux now includes support for capturing Brazilian television, which uses the ISDB-T standard.

Outdated section

Support for ISDB-T devices is currently in its infancy under Linux, having only been added to the Linux DVB S2API in September 2009. The number of drivers and supported devices will surely grow in time.

How do I make ISDB-T devices work with the current dvb-apps version?

Currently, some changes are needed within the dvb-apps in order to support the new DVBS2API parameters for ISDB-T. Until those changes are implemented there, and within userspace apps, you will need to use the DVB-T format.

In the case of ISDB-T, the current implementations (Brazil and Japan) use 6 MHz bandwidth with the same ISDB-T Frequency Table. In the future, this is likely to change.

For the device to work, the first step is to seek for the existing channels. This is done by running the 'scan' application: 

 scan FrequencyTable >channels.conf

Then, a DVB-T userspace application can be used to play the stream. In the case of Brazil, the application needs to support H.264 for video, HE-AAC for audio, and PMT tables at the mpeg-ts. Currently, only vlc and the newest development versions of mplayer are known to support. However, some stream types are known to not work with none of those two applications, due to some existing bugs.
