Abstract: This paper presents an accurate model for inter color space conversion (RGB to YCbCr), for transmission through HDMI specification, for ARINC 818 transceiver, which is based on the simplified shift and sub sampling recovery. Real-time video processing heavily relies on the color space conversion. Due to the real-time requirement, the traditional conversion methods often suffer from the moderate conversion speed, inaccuracy and low video quality.[5]

Keywords: HDMI, ARINC, video conversion, RGB, YCbCr.
