πŸ’… enum tuner_pad_index(9) πŸ’…

okay so bestie, this page is from the Kernel API Manual, and it’s giving β€œtiny enum, very main character energy.” We’re talking about enum tuner_pad_index β€” the pad index for MEDIA_ENT_F_TUNER. It’s short, it’s specific, and every constant below is doing its little job. πŸ’–


🌸 NAME 🌸

enum tuner_pad_index β€” tuner pad index for MEDIA_ENT_F_TUNER.

✨ SYNOPSIS ✨

enum tuner_pad_index {
    TUNER_PAD_RF_INPUT ,
    TUNER_PAD_OUTPUT ,
    TUNER_PAD_AUD_OUT ,
    TUNER_NUM_PADS

};

πŸŽ€ Constants πŸŽ€

  • TUNER_PAD_RF_INPUT β€” the Radiofrequency (RF) sink pad. It’s usually linked to a RF connector entity. πŸ’…
  • TUNER_PAD_OUTPUT β€” the tuner video output source pad. It 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 β€” the 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, and that 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 β€” the number of pads of the tuner. Slay.
