- <entry>Analog video decoder, the basic function of the video decoder
- is to accept analogue video from a wide variety of sources such as
- broadcast, DVD players, cameras and video cassette recorders, in
- either NTSC, PAL, SECAM or HD format, separating the stream
- into its component parts, luminance and chrominance, and output
- it in some digital video standard, with appropriate timing
- signals.</entry>

- <entry><constant>MEDIA_ENT_F_TUNER</constant></entry>
- <entry>Digital TV, analog TV, radio and/or software radio tuner,
- with consists on a PLL tuning stage that converts radio
- frequency (RF) signal into an Intermediate Frequency (IF).
- Modern tuners have internally IF-PLL decoders for audio
- and video, but older models have those stages implemented
- on separate entities.
- </entry>
- </row>
- <row>
- <entry><constant>MEDIA_ENT_F_IF_VID_DECODER</constant></entry>
- <entry>IF-PLL video decoder. It receives the IF from a PLL
- and decodes the analog TV video signal. This is commonly
- found on some very old analog tuners, like Philips MK3
- designs. They all contain a tda9887 (or some software
- compatible similar chip, like tda9885). Those devices
- use a different I2C address than the tuner PLL.

- <entry><constant>MEDIA_ENT_F_IF_AUD_DECODER</constant></entry>
- <entry>IF-PLL sound decoder. It receives the IF from a PLL
- and decodes the analog TV audio signal. This is commonly
- found on some very old analog hardware, like Micronas
- msp3400, Philips tda9840, tda985x, etc. Those devices
- use a different I2C address than the tuner PLL and
- should be controlled together with the IF-PLL video
- decoder.

- <entry>Video composer (blender). An entity capable of video
- composing must have at least two sink pads and one source
- pad, and composes input video frames onto output video
- frames. Composition can be performed using alpha blending,
- color keying, raster operations (ROP), stitching or any other
- means.

- <row>
- <entry><constant>MEDIA_ENT_F_PROC_VIDEO_PIXEL_FORMATTER</constant></entry>
- <entry>Video pixel formatter. An entity capable of pixel formatting
- must have at least one sink pad and one source pad. Read
- pixel formatters read pixels from memory and perform a subset
- of unpacking, cropping, color keying, alpha multiplication
- and pixel encoding conversion. Write pixel formatters perform
- a subset of dithering, pixel encoding conversion and packing
- and write pixels to memory.
- </entry>
- </row>
- <row>
- <entry><constant>MEDIA_ENT_F_PROC_VIDEO_PIXEL_ENC_CONV</constant></entry>
- <entry>Video pixel encoding converter. An entity capable of pixel
- enconding conversion must have at least one sink pad and one
- source pad, and convert the encoding of pixels received on
- its sink pad(s) to a different encoding output on its source
- pad(s). Pixel encoding conversion includes but isn't limited
- to RGB to/from HSV, RGB to/from YUV and CFA (Bayer) to RGB
- conversions.
- </entry>
- </row>
- <row>
- <entry><constant>MEDIA_ENT_F_PROC_VIDEO_LUT</constant></entry>
- <entry>Video look-up table. An entity capable of video lookup table
- processing must have one sink pad and one source pad. It uses
- the values of the pixels received on its sink pad to look up
- entries in internal tables and output them on its source pad.
- The lookup processing can be performed on all components
- separately or combine them for multi-dimensional table
- lookups.
- </entry>
- </row>
- <row>
- <entry><constant>MEDIA_ENT_F_PROC_VIDEO_SCALER</constant></entry>
- <entry>Video scaler. An entity capable of video scaling must have
- at least one sink pad and one source pad, and scale the
- video frame(s) received on its sink pad(s) to a different
- resolution output on its source pad(s). The range of
- supported scaling ratios is entity-specific and can differ
- between the horizontal and vertical directions (in particular
- scaling can be supported in one direction only). Binning and
- skipping are considered as scaling.
- </entry>
- </row>
- <row>
- <entry><constant>MEDIA_ENT_F_PROC_VIDEO_STATISTICS</constant></entry>
- <entry>Video statistics computation (histogram, 3A, ...). An entity
- capable of statistics computation must have one sink pad and
- one source pad. It computes statistics over the frames
- received on its sink pad and outputs the statistics data on
- its source pad.
