WinTV-HD
Model 00698 Functional Specification
Revision 1.3 – November 3, 2000
Overview
The
WinTV-HD 00698 is a PCI card capable of
receiving and decoding both ATSC 8VSB Digital Television (DTV) transmissions and
NTSC analog television transmissions.
When receiving DTV transmissions the WinTV-HD transfers
a 19.4 Megabit per second demodulated transport-level data stream to its
on-board hardware MPEG decoder chip, which is equipped with 16 megabytes of
local memory. The MPEG decoder chip
decodes the selected video program, and makes the audio and data portions of
the transport stream available to the PC’s CPU for further processing.
The decoded video is displayed in either of two
software-selectable ways, (1) by passing the video to the PC’s VGA subsystem
via the PCI bus in 640x480 resolution, or (2) by driving an RGB (VGA) or YPrPb
(HDTV component) monitor directly in resolutions up to 1920x1080i. A loop cable and an on-board analog switch
are provided to allow the high resolution video to be displayed on the PC’s
monitor. The AC-3 digital audio portion
of a DTV transmission is decoded in software by the PC’s CPU, and output
through the PC’s sound subsystem.
Optionally, the board can be jumpered to output the AC-3 digital audio
via an S/PDIF connector.
When receiving NTSC analog transmissions, the tuned
analog composite video is first digitized, and then passed into the MPEG
decoder chip for display via either of the methods described above. The analog audio portion of an NTSC
transmission is first passed through a BTSC stereo decoder which implements
dbx-TV noise reduction, and then onward to the PC’s sound subsystem via either
an internal (CD-ROM-type) or external (1/8” audio jack) line-level stereo audio
cable.
