Texas Instruments’ (TI) newest
addition to an already market
proven portfolio of video decoders
provides unparalleled video quality
and features not found in other
decoders. The TVP5160 device,
a high-quality, high-performance
digital video decoder (NTSC/
PAL/SECAM) digitizes and
By implementing a 3D comb
filter, the TVP5160 provides the
highest quality video available
today. The 3D comb filter, which
separates the composite signal into
both Y and C channels to reduce
both cross-luma and cross-chroma
artifacts, is applied on both NTSC
and PAL video inputs. Through a
highly sophisticated motion
detection algorithm, the TVP5160
successfully applies TI’s patented
2D, 5-line comb filter to those
portions of the picture that are
moving but also utilizes TI’s 3D
comb filter to provide cleaner,
crisper images to the static
In addition to the 3D comb
filter, the TVP5160 can
simultaneously provide 3D noise
reduction to reduce temporal
noise on CVBS, S-Video or
component inputs and time-based
correction (TBC) to correct time-
based errors introduced by VCRs.
TI’s patented sync detector
provides high-quality support of
VCR trick modes, weak and noisy
signals as well as other nonstandard
video sources. 480p (576p) inputs
are also supported to provide the
high-quality progressive video
inputs from other video devices
including DVD players. This
balance of features offers
decodes all popular baseband
analog video formats into digital
component video.
Target applications include:
• CRT, LCD, DLPTM and plasma TV
• DVD-Recorder
• High-end set-top box
portions of the picture.

each A/D converter, each analog
channel contains an analog circuit,
which clamps the input to a
reference voltage and applies a
programmable gain and offset.

component inputs and the CVBS
inputs are sampled at 54 MHz
alternately, then decimated to the
1X rate. Composite or S-Video
signals are sampled at 4× the pixel
rate and are then decimated to the
1X rate. All sampling is line locked
for correct pixel alignment.
