6 Digital TV Demux
9 The Kernel Digital TV Demux kABI defines a driver-internal interface for
11 demux layer. It is only of interest for Digital TV device driver writers.
12 The header file for this kABI is named ``demux.h`` and located in
15 The demux kABI should be implemented for each demux in the system. It is
16 used to select the TS source of a demux and to manage the demux resources.
17 When the demux client allocates a resource via the demux kABI, it receives
20 Each demux receives its TS input from a DVB front-end or from memory, as
21 set via this demux kABI. In a system with more than one front-end, the kABI
