Components for receiving and processing DVB transmissions

These components provide facilities to receive, demultiplex and process Terrestrial Digital Television broadcasts broacast using the DVB-T standard.

To tune to and receive such signals requires an appropriate DVB-T receiver adaptor and drivers and firmware. Support for this is currently only available for the Linux platform (via the linux dvb-api).

Windows and Mac are currently not supported.

These components require the python-dvb3 and support-code bindings to be compiled.

Component overview

To receive and demuliplex see:

• Kamaelia.Device.DVB.Core.DVB_Multiplex -- a simple tuner/receiver
• Kamaelia.Device.DVB.Core.DVB_Demuxer -- a simple demultiplexer
• Kamaelia.Device.DVB.Tuner.Tuner -- a more flexible tuner
• Kamaelia.Device.DVB.DemuxerService. -- a more flexible demuliplexer
• Kamaelia.Device.DVB.SoftDemux.DVB_SoftDemux -- a drop in replacement for the simple demuliplexer optimised to run faster

To extract and parse metadata from the stream:

• Kamaelia.Device.DVB.Parse -- a large suite of components for parsing most PSI tables
• Kamaelia.Device.DVB.EIT -- a simple set of components for parsing EIT (now & next events) tables
• Kamaelia.Device.DVB.Nowext -- components for simplifying raw parsed EIT tables into useful events - eg. signalling the start of a programme
• Kamaelia.Device.DVB.PSITables -- some utility components for processing PSI tables
