Digital audio and video couple on the DVI link

Silicon Image is bringing high-definition (HD) Hollywood studio content directly to consumers with the introduction of audio capability on the (DVI) link.

Silicon Image took a step forward in the effort to bring high-definition (HD) Hollywood studio content directly to consumers with the introduction of audio capability on the Digital Visual Interface (DVI) link.

The SiI 190 PanelLink transmitter and SiI 991 PanelLink receiver are the first semiconductor chips to couple digital audio and video data in a single, secure, all-digital interface capable of supporting uncompressed HD content.

The SiI 190 transmitter is designed for an array of consumer electronics (CE) host devices, including set-top boxes, DVD players, D-VHS players and game consoles, while the SiI 991 receiver is compatible with CRT, LCD, plasma and DLP-based HDTVs and projectors.

Building upon the recent availability of High-bandwidth Digital Content Protection (HDCP), audio adds yet another layer of functionality to the DVI link.

DVI with HDCP enables the encryption of premium HD video between digital CE host and display devices, addressing the motion picture industry’s concerns about unauthorised duplication and piracy of their most valuable copyrighted content.

With the addition of audio capability to the same DVI link, CE manufacturers can now transmit and receive all digital surround-sound formats, including Dolby Digital, Digital Theatre Systems (DTS) and PCM Stereo, while eliminating the need for a separate audio connector and cables. No additional pins are used as the audio data is embedded within the existing DVI clock channel with an advanced method of data modulation developed by Silicon Image.

By reducing the number of system components, embedded audio simplifies OEM system design, lowers component costs and improves ease of use for the consumer.

Warner Bros., Disney, Universal Studios and Fox, as well as CE manufacturer JVC and satellite broadcast provider Echostar, have all endorsed DVI with HDCP.

The SiI 190 transmitter and SiI 991 receiver are projected to be sampling in Q2 2001 and begin shipping in production volumes during Q3 2001.
