Overview: Reception quality
Reception quality describes the signal conditions and data errors affecting a received television service.
Signal strength and signal quality measure different properties. Uncorrectable errors describe a later result after the reception and correction path has done its work. Reading those observations together is more informative than selecting one high-looking signal number as proof of reliable programme delivery.
Signal strength
TV signal strength is a receiver-reported input-level measurement or estimate whose units, calibration and observation context determine its interpretation.Signal quality
TV signal quality describes receiver-specific digital-recovery measurements such as carrier/noise, modulation-error or correction-related observations rather than input power alone.Uncorrectable reception errors
Uncorrectable reception errors indicate data the receiver’s defined correction stage could not recover, with counter scope and later media dependencies determining their significance.
