SocketProtocol for the dvb frontend device. More...
#include <senf/Socket/Protocols/DVB/DVBFrontendHandle.hh>
Detailed Description
SocketProtocol for the dvb frontend device.The DVB frontend device controls the tuner and DVB demodulator hardware. ATTENTION! Some calls are not supported by real life drivers, known issues:
Cinergy T� getParameter is not supported Cinergy T� in getEvent fe_status_t will be set but dvb_frontend_parameters will be stay untouched Cinergy DT XS bitErrorRate is not supported
This dues to the lack of driver implementation. There could be restrictions also for other DVB devices!

| unsigned senf::DVBFrontendSocketProtocol:: | ||||
| available | () | |||
Returns always 0.
Returns always 0, since the DVB frontend socket is not readable.
Implements senf::SocketProtocol.
Definition at line 55 of file DVBFrontendHandle.cc.
| uint32_t senf::DVBFrontendSocketProtocol:: | ||||
| bitErrorRate | () | |||
Returns the current bit error rate for the signal.
Returns the bit error rate for the signal currently received/demodulated by the front-end. For this method, read-only access to the device is sufficient.
Definition at line 240 of file DVBFrontendHandle.cc.
| bool senf::DVBFrontendSocketProtocol:: | ||||
| eof | () | |||
Returns always false.
Returns always false, since the DVB frontend socket does not support the notion of EOF.
Implements senf::SocketProtocol.

| uint32_t senf::DVBFrontendSocketProtocol:: | ||||
| uncorrectedBlocks | () | |||
Returns the number of uncorrected blocks.
Returns the number of uncorrected blocks detected by the device driver during its lifetime. For meaningful measurements, the increment in block count during a specific time interval should be calculated. For this command, read-only access to the device is sufficient. Note that the counter will wrap to zero after its maximum count has been reached.
