Glossary
========
.. note::
The goal of this section is to standardize the terms used within the media
userspace API documentation. This is Work In Progress.
.. Please keep the glossary entries in alphabetical order
.. glossary::
Bridge Driver
A :term:`Device Driver` that implements the main logic to talk with
media hardware.
CEC API
**Consumer Electronics Control API**
An API designed to receive and transmit data via an HDMI
CEC interface.
See :ref:`cec`.
Data Unit
Unit of data transported by a bus. On parallel buses, the data unit
consists of one or more related samples while on serial buses the data
unit is logical. If the data unit is image data, it may also be called a
pixel.
Device Driver
Part of the Linux Kernel that implements support for a hardware
component.
Device Node
A character device node in the file system used to control and
transfer data in and out of a Kernel driver.
Digital TV API
**Previously known as DVB API**
An API designed to control a subset of the :term:`Media Hardware`
that implements digital TV (e. g. DVB, ATSC, ISDB, etc).
See :ref:`dvbapi`.
DSP
**Digital Signal Processor**
A specialized :term:`Microprocessor`, with its architecture
optimized for the operational needs of digital signal processing.
FPGA
**Field-programmable Gate Array**
An :term:`IC` circuit designed to be configured by a customer or
a designer after manufacturing.
See https://en.wikipedia.org/wiki/Field-programmable_gate_array.
Hardware Component
A subset of the :term:`Media Hardware`. For example an :term:`I²C` or
:term:`SPI` device, or an :term:`IP Block` inside an
:term:`SoC` or :term:`FPGA`.

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.
