HDMI (High Definition Multimedia Interface) is the first industry-supported, superior, uncompressed, all-digital audio/video interface. It provides an interface between any audio/video source, such as a set-top box or a DVD player, and an audio and/or video monitor, such as a digital television (DTV) or A/V receiver. Its simple user-friendly connector replaces the maze of cabling behind the entertainment center.
The HDMI transmitter provides a very time-to-market and cost effective solution for multimedia controller vendor to implement the HDMI operation. It performs all necessary operation defined in HDMI specification 2.0b that is backward compatible to HDMI series specification such as HDMI 1.2, 1.3, 1.4… for TMDS encoding.
HDCP1.4 and 2.2 is also applied to the HDMI transmitter. It provides both secure video and audio data encryption to protect the content. CEC is a feature of high-level control function between all the audiovisual products in a user’s home entertainment environment. It simplifies the control flow of all devices
