Description
The TVP5147M1 device is a high-quality, single-chip digital video decoder that digitizes and decodes all
popular baseband analog video formats into digital component video. The TVP5147M1 decoder supports
the analog-to-digital (A/D) conversion of component YPbPr signals, as well as the A/D conversion and
decoding of NTSC, PAL, and SECAM composite and S-video into component YCbCr. This decoder
includes two 11-bit 30-MSPS A/D converters (ADCs). Preceding each ADC in the device, the
corresponding analog channel contains an analog circuit that clamps the input to a reference voltage and
applies a programmable gain and offset. A total of ten video input terminals can be configured to a
combination of YPbPr, CVBS, or S-video video inputs.
Composite or S-video signals are sampled at 2× the ITU-R BT.601 clock frequency, line-locked alignment,
and are then decimated to the 1× pixel rate. CVBS decoding uses five-line adaptive comb filtering for both
the luma and chroma data paths to reduce both cross-luma and cross-chroma artifacts. A chroma trap
filter is also available. On CVBS and S-video inputs, the user can control video characteristics such as
contrast, brightness, saturation, and hue via an I2C host port interface. Furthermore, luma peaking
(sharpness) with programmable gain is included, as well as a patented chroma transient improvement
(CTI) circuit.
The following output formats can be selected: 20-bit 4:2:2 YCbCr or 10-bit 4:2:2 YCbCr.
The TVP5147M1 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 TVP5147M1 decoder includes methods for advanced vertical blanking interval (VBI) data retrieval.
The VBI data processor (VDP) slices, parses, and performs error checking on teletext, closed caption
(CC), 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 TVP5147M1 decoder can pass through the
output formatter 2× sampled raw luma data for host-based VBI processing.
The main blocks of the TVP5147M1 decoder include:
Robust sync detection for weak and noisy signals as well as VCR trick modes
Y/C separation by 2-D 5-line adaptive comb or chroma trap filter
Two 11-bit, 30-MSPS A/D converters with analog preprocessors [clamp and automatic gain control
(AGC)]
Analog video output
Luminance processor
Chrominance processor
Clock/timing processor and power-down control
Software-controlled power-saving standby mode
Output formatter
I2C host port interface
VBI data processor
Macrovision copy protection detection circuit (Type 1, 2, 3, and separate color stripe detection)
3.3-V tolerant digital I/O ports
