RGB to CCIR 601 / 656 Encoder

Overview

Key Features

• The DB1892 performs the following video signal processing functions:
• Color Space Converter - Inputs RGB 24-bit data and sync signals VSYNC, HSYNC, & Date Enable from a LCD Controller. The Color Space Converter converts the 4:4:4 sampled RGB pixels to component luma and chroma digital video 4:4:4 YCbCr.
• Chroma Resampler - The Chroma Resampler down converts the 4:4:4 YCbCr to 4:2:2 YCbCr, in order to meet the ITU-R BT.601 requirements of the ITURBT. 656 Encoder.
• BT.656 Encoder - Encodes the 4:2:2 YCbCr component digital video with synch signals to conform to the ITU-RBT.656 digital coding standard.

Benefits

• The DB1892 RGB to CCIR 601 / 656 Encoder is a system-level IP integrating the Color Space Converter, Chroma Resampler, & BT.656 Encoder functions for full transformation from the RGB color space to the BT.656 4:2:2 Y’CbCr color space & BT.656 framing. The DB1892 supports the following bus interfaces for configuration:
• AMBA 2.0 AHB Master, AHB Slave
• AMBA 1.0 AXI , AXI4
• CoreConnect PLB, OPB
• Avalon, Qsys
• OCP 2.2
• PCI
• Hard-coded parameters requiring no bus fabric interface

Deliverables

• Verilog RTL Source or technology-specific netlist.
• Comprehensive testbench suite with expected results.
• Synthesis scripts.
• Installation & Implementation Guide.
• Technical Reference Manual.
