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 (that is, 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.
• 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.
• External HSYNC and VSYNC signals available on silicon revision 2.x devices. For more details,
see below.
– 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.
