CONSTANTS

TUNER_PAD_RF_INPUT

Radiofrequency (RF) sink pad, usually linked to a RF connector entity.

TUNER_PAD_OUTPUT

Tuner video output source pad. Contains the video chrominance and luminance or the hole bandwidth of the signal converted to an Intermediate Frequency (IF) or to baseband (on zero-IF tuners).

TUNER_PAD_AUD_OUT

Tuner audio output source pad. Tuners used to decode analog TV signals have an extra pad for audio output. Old tuners use an analog stage with a saw filter for the audio IF frequency. The output of the pad is, in this case, the audio IF, with should be decoded either by the bridge chipset (that's the case of cx2388x chipsets) or may require an external IF sound processor, like msp34xx. On modern silicon tuners, the audio IF decoder is usually incorporated at the tuner. On such case, the output of this pad is an audio sampled data.

TUNER_NUM_PADS

Number of pads of the tuner.
