STRUCT ANALOG_PARAMETERS(9)

💅 struct analog_parameters(9) — kernel API manual, bestie edition

okay so first things first: this is a kernel API manual page, we're in analog_parameters territory, and honestly? it's giving "small struct, big responsibilities" energy. let's get into it 🎀

---

✨ NAME ✨

struct analog_parameters — the parameters you need to tune into an analog/radio channel 📻✨

---

🌸 SYNOPSIS 🌸

struct analog_parameters {
    unsigned int frequency;
    unsigned int mode;
    unsigned int audmode;
    u64 std;
 };

look at her. four fields. no notes. 🫶

💅 Members 💅

okay this is the part where we meet the whole squad, one by one:

• frequency — the frequency your analog TV tuner is using, either in 62.5 kHz steps (that's the TV life) or 62.5 Hz (that's the radio life). two very different vibes, same field, iykyk. 📡
• mode — the tuner mode, defined over on enum v4l2_tuner_type. it's literally the tuner's whole personality. 🧚
• audmode — the audio mode, defined exactly the way the rxsubchans field is at videodev2.h, e. g. V4L2_TUNER_MODE_*. audio said "i'm main character." 🎧
• std — the TV standard bitmap, defined at videodev2.h, e. g. V4L2_STD_*. the blueprint. the standard. literally in the name bestie. 🌈

🦋 Description 🦋

so here's the lore: hybrid tuners should be supported by both the V4L2 and DVB APIs — both, not one, that's the whole point of "hybrid." 🔥

this struct holds the data that's used by the V4L2 side of that equation.

and here's the cute little hack: to avoid dependencies from V4L2 headers, all the enums in here are declared as integers. no header drama, no #include chaos, just ints. slay. 💅✨

okay that's the page!! 💖 this one lives in ./include/media and the version stamp says October 2026 — so like, keep that in mind for your citation era. mwah, study hard, drink water, and remember: all enums here are declared as integers. periodt. 🎀✨🦋
