IToiFrontendService::TToiPropertySequence | ExtendedProperties |
A measure of the channel bit error rate in errors/10^9 bits. When the receiver does not have channel lock this value is -1.
Centre frequency of a frontend.
The extended properties defined for the frontend.
IToiFrontendService::TToiFrontendCapabilities IToiFrontendService::TToiFrontendInfo::FrontendCapabilities |
The frontend capabilities information.
True if the frontend is locked to a channel, i.e. the tuner has acquired a lock and the demodulator is able to decode the digital data stream with reasonable accuracy.
The tuner input level in dBm. When not available the value is -1.
The session identifier. If the frontend is not in use by a media session, the value is -1, i.e. no media session associated.
Signal-to-noise ratio in tenth of a dB, i.e. the value 251 means 25.1 dB. When the receiver does not have channel lock this value is -1.
The number of uncorrected blocks since the previous call to GetFrontendInfo(). When the frontend does not have channel lock this value is -1.
