Digital Visual Interface (DVI) standard, which was established in 1999, by the Digital Display Working Group (DDWG), to maximize resolution of digital flat panel displays is now speedily losing its glory, mainly owing to the competitions offered by other emerging technologies.
According to a recent survey report by In-Stat, in the PC market, along with other technologies, High-definition Multimedia Interface (HDMI) and the DisplayPort standard are offering a tough competition to DVI. Thus, DVI will decline from 112 million device shipments in 2007 to just 3 million device shipments in 2011.
Although DVI and HDMI, are related, high-bandwidth, unidirectional, uncompressed digital interface standards, according to Brian O’Rourke, an In-Stat analyst, “HDMI’s success continues to be enormous, especially in the Consumer Electronics (CE) segment.”
It may contextually be noted that the most significant difference between HDMI and DVI is that HDMI transfers the video and audio signal, whereas DVI carries only the video signal. According to HDMI proponents, HDMI provides the highest quality video and audio, it reduces cable-confusion by reducing the number of cables behind the display. Also, it automatically configures remote controls of devices connected by HDMI, automatically adjusts video content to most effective format. However, HDMI is compatible with DVI, and the HDMI input is similar to a USB connector on a PC.
Brian also adds, “Close to 90% of digital television (DTV) shipments in 2008 are expected to include HDMI. In addition, HDMI penetration of large markets such as set top boxes continues to increase.”
In-Stat report categorically predicts, 143 million HDMI-enabled devices shipped in 2007. It may be recalled that recently at the 2008 International Consumer Electronics Show (CES), HDMI Licensing, LLC, the agent responsible for licensing the HDMI specification, has proudly announced that more than 750 CE and PC manufacturers have adopted the HDMI specification, up from 574 adopters one year ago.
Thus, adoption rate of HDMI specification by manufacturers is steadily increasing worldwide. In CES 2008, a fairly good number of products have been displayed, all of which are HDMI1.3-enabled. Channel partners need to make a note of this, – in the coming days, gradually DVI-based devices will turn out to be antique products.
