alternately, then decimated to the 1
× rate. Composite or S-Video signals are sampled at 4× the ITU-R
BT.601 clock frequency (54 MHz), line-locked for correct pixel alignment, and are then decimated to the
1
× rate. CVBS decoding uses advanced 3D Y/C filtering and 2-dimensional complementary 5-line adaptive
comb filtering for both the luma and chroma data paths to reduce both cross-luma and cross-chroma
artifacts. 3D Y/C color separation may be used on both PAL and NTSC video signals. A chroma trap filter
is also available. On CVBS and Y/C inputs, the user can control video characteristics such as hue,
contrast, brightness, and saturation via an I2C host port interface. Furthermore, luma peaking with
programmable gain is included, as well as a patented color transient improvement (CTI) circuit.
Attenuation at higher frequencies or asymmetrical color subcarrier sidebands are compensated using the
IF compensation block. Frame adaptive noise reduction may be applied to reduce temporal noise on
CVBS, S-Video, or component inputs.
3D noise reduction and 3D Y/C separation may be used at the same time or independently.
The TVP5160 decoder uses Texas Instruments' patented technology for locking to weak, noisy, or
unstable signals and can auto-detect between broadcast quality and VCR-style (nonstandard) video
sources.
The TVP5160 decoder generates synchronization, blanking, field, active video window, horizontal and
vertical syncs, clock, genlock (for downstream video encoder synchronization), host CPU interrupt and
programmable logic I/O signals, in addition to digital video outputs.
The TVP5160 decoder includes methods for advanced vertical blanking interval (VBI) data retrieval. The
VBI data processor (VDP) slices and performs error checking on teletext, closed caption, and other VBI
data. A built-in FIFO stores up to 11 lines of teletext data, and, with proper host port synchronization,
full-screen teletext retrieval is possible. The TVP5160 decoder can pass through the output formatter 2
×
sampled raw Luma data for host-based VBI processing.
Digital RGB overlay can be synchronously switched with any video input, with all signals being
oversampled at 4
× the pixel rate.
The TVP5160 detailed functionality includes:
Two high-speed, 60-MSPS, 11-bit, A/D channels with programmable clamp and gain control
The two ADCs can sample CVBS or S-Video at 54 MHz. YPbPr/RGB is multiplexed between the two
ADCs which sample at 54 MHz giving a channel sampling frequency of 27 MHz.
Supports ITU-R BT.601 pixel sampling frequencies.
Supports ITU-R BT.601 sampling for both interlaced and progressive signals.
RGB-to-YUV color space conversion for SCART signals
3D Y/C separation or 2D 5-line (5H) adaptive comb and chroma trap filter
3-frame NTSC and PAL color separation
Temporal frame recursive noise reduction (3DNR)
Frame recursive noise reduction can be applied to interlaced CVBS, S-Video, or component inputs for
interlaced signals. Noise reduction can be used at the same time as 3D Y/C separation. Noise
reduction cannot be applied to progressive video signals.
Line-based time base correction (TBC)
Line-based time correction corrects for horizontal phase errors encountered during video decoding up
to
±80 pixels of error. This improves the output video quality from jittery sources such as VCRs. It also
reduces line tearing during video trick modes such as fast forward and rewind.
IF compensation
Attenuation at higher frequencies or asymmetrical color subcarrier sidebands are compensated using
the IF compensation block
Fast switch 4
× oversampling for digital RGB overlay signals for switching between any CVBS, S-Video,
or component video inputs
The fast switch overlay signals (FSO, DR, DG, DB) are oversampled at 4
× the pixel clock frequency.
The phase of these signals is used to mix the selected video input format and a digital RGB input to
