8.10 High-Definition Video Processing Subsystem (HDVPSS)

The device High-Definition Video Processing Subsystem (HDVPSS) provides a video input interface for

external imaging peripherals (i.e., image sensors, video decoders, etc.) and a video output interface for

display devices, such as analog SDTV displays, analog/digital HDTV displays, digital LCD panels, etc. It

includes HD and SD video encoders, and an HDMI transmitter interface.

The device HDVPSS features include:

•

High quality (HD) and medium quality (SD) display processing pipelines with de-interlacing, scaling,

noise reduction, alpha blending, chroma keying, color space conversion, flicker filtering, and pixel

format conversion.

•

HD/SD compositor features for PIP support and video mosaic support.

•

Format conversions (up to 1080p 60 Hz) include scan format conversion, scan rate conversion,

aspect-ratio conversion, and frame size conversion.

•

Supports additional video processing capabilities by using the subsystem's memory-to-memory feature.

•

Two parallel video processing pipelines support HD (up to 1080p60) and SD (NTSC/PAL)

simultaneous outputs.

–

HD analog component output with OSD and embedded timing codes (BT.1120)

•

3-channel HD-DAC with 12-bit resolution.

–

SD analog output with OSD with embedded timing codes (BT.656)

•

Simultaneous component, S-video and composite

•

4-channel SD-DAC with 10-bit resolution

•

Options available to support MacroVision and CGMS-A (contact local TI Sales rep for

information).

–

Digital HDMI 1.3a compliant transmitter (for details, see Section 8.9, High-Definition Multimedia

Interface (HDMI)).

•

Up to two (one 16/24/30-bit and one 16-bit) digital video outputs (up to 165 MHz).

–

VOUT[0] can output up to 30-bit video and supports RGB, YUV444, Y/C and BT.656 modes.

–

VOUT[1] can output up to 16-bit video and supports Y/C and BT.656 modes.

•

Two (one 16/24-bit and one 16-bit) independently configurable external video input capture ports (up to

165 MHz).

–

16/24-bitHD digital video input or dual clock independent 8-bit SD inputs on each capture port.

•

VIN[0] can accept single-channel 16/24-bit (YCbCr/RGB) video or dual-channel 8-bit (YCbCr)

video.

•

VIN[1] can accept single-channel 16-bit (YCbCr) video or dual-channel 8-bit (YCbCr) video.

–

Embedded sync and external sync modes are supported for all input configurations.

–

De-multiplexing of both pixel-to-pixel and line-to-line multiplexed streams, effectively supporting up

to 16 simultaneous SD inputs with a glueless interface to an external multiplexer such as the

TVP5158.

–

Additional features include: programmable color space conversion, scaler and chroma

downsampler, ancillary VANC/VBI data capture (decoded by software), noise reduction.

•

Availability of a combination of these digital video input/output port configurations, control signals for

multiple 8-bit ports, as well as separate synchronization signals is limited by the device pin multiplexing

(for details, see Section 4.4). The following video inputs/outputs are not multiplexed and are always

available:

–

SD DAC composite, S-video, component out

–

HD DAC component out

–

HDMI output (same as VOUT[1])

–

16-bit VOUT[0] (embedded sync)

–

Single 16-bit/dual 8-bit VIN[0] (embedded sync).
