============
Introduction
============
The media subsystem consists on Linux support for several different types
of devices:
- Audio and video grabbers;
- PC and Laptop Cameras;
- Complex cameras found on Embedded hardware;
- Analog and digital TV;
- HDMI Customer Electronics Control (CEC);
- Multi-touch input devices;
- Remote Controllers;
- Media encoders and decoders.
Due to the diversity of devices, the subsystem provides several different
APIs:
- Remote Controller API;
- HDMI CEC API;
- Video4Linux API;
- Media controller API;
- Video4Linux Request API (experimental);
- Digital TV API (also known as DVB API).Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
