HDMI: the need for a Robust Cost Effective Solution Deirdre Mathelin and Dr. John Horan, RedMere Technology Ltd. HDMI? (High Definition Multimedia Interface) adoption has been growing rapidly since its first introduction at International Consumer Electronics Show (CES) in January 2003. Manufacturers and consumers alike have embraced the new digital interface standard as synonymous to high definition television.Today the standard is transitioning from its position on the market as a single port feature on high-end set top boxes and TVs to a multiple-port feature incorporated on multiple applications. With this comes increased pressure to deliver more cost-effective products traded off with the cost and time to take new products through the rigorous HDMI? compliance testing. Such a trade-off centres around how to deal with the challenges of transmitting and receiving high bandwidth video signals transported over cables of varying quality and length. TV manufacturers need new approaches which deliver lower cost while not compromising quality.
