  Dear Supporter

Which video decoder-encoder can you propose for a good video performance, supporting 3D comb filter  to generate a good and sharp video? 

 

The table below lists the specific input/output requirements for the decoder & encoder:

 

 

 

Decoder

Criteria

Requirement

Analog inputs

composite (CVBS)

Video formats @ input

NTSC,PAL

Video data outputs

16/20/24/30 4:2:2 YCrCb (any one of them is acceptable)

resolutions 480i60 (NTSC) & 576i50 (PAL)

Video ctrl outputs

HS,VS,PCLK – must ; DE – nice to have

Pixel clock output frequency

  1. 13.5/27MHz (configurable)

Video processing

3D comb filter

Data rate

SDR (not DDR)

Command interface

I2C

 

 

 

 

 

Encoder

Criteria

Requirement

Analog output

Composite (CVBS)

Video formats @ output

Composite NTSC,PAL

Video data inputs

16/20/24/30 4:4:4 RGB/YCrCb

If not available 4:4:4, send recommendation for 4:2:2 encoder

Video ctrl inputs
