DTV(4)

🎀 NAME 🎀

dtv — interface for digital television 💖

Okay bestie, this is dtv(4) from the Kernel Interfaces Manual, and we are absolutely doing this. It’s giving “digital TV but make it a kernel interface,” and I’m obsessed.

✨ SYNOPSIS ✨

dtv* at dtvbus?

#include <dev/dtv/dtvio.h>
#include <dev/dtv/dtvio_demux.h>
#include <dev/dtv/dtvio_frontend.h>

💅 DESCRIPTION 💅

The machine-independent dtv interface provides support for digital television (DTV). A subset of the Linux Digital Video Broadcasting (DVB) APIs is supported. In particular, dtv provides the DVB frontend and demodulator APIs. Slay. ✨

🌈 SUPPORTED DEVICES 🌈

The following machine-independent devices are supported:

• auvitek(4) — Auvitek AU0828-based video capture cards
• emdtv(4) — EM28XX-based DTV cards

Quick note, bestie: the dtv device drivers are generally only available as kernel modules; see module(7) and modload(8) for additional details. Also refer to dtviic(4) for details about the supported demodulators and tuners. 👑

🦋 FILES 🦋
