MonitorLink™

MonitorLink is a new digital interface introduced in

Mitsubishi's 2003-2004 model line, including the

V23 chassis.

MonitorLink provides a proprietary connection for Mitsubishi's HD-5000, Monitor/Receiver, allowing Mitsubishi's upgradeability promise to be fulfilled using a digital, rather than analog, interface.

While MonitorLink is a proprietary connection, it uses industry standard technologies that may pro- vide even more versatility.

•RS-232C- Provides device communication and control.

•Audio - Standard analog stereo connections.

• DVI - (Digital Visual Interface) Provides a	Figure 9: MonitorLink Input
digital video connection.	Digital Visual Interface (DVI)

RS-232C…The RS-232C connection interfaces communications and control between the receiver/ controller and display. Commands such as Power On, Input, Mute, etc., make the system operate as one via the customer's remote control.

Audio… Analog Left and Right Audio connectors are provided for the set's internal audio/speaker sys- tem. The V23 chassis has digital audio outputs and IEEE1394 for more advanced connections with an external A/V receiver.

DVI… Technicians experienced with computer monitors may already be familiar with DVI and its features. However, because it is new to home the- ater, it will be covered here further.

DVI was originally designed by the Digital Display Working Group (DDWG) to provide a universally accepted digital connection between a PC and a dis- play device.

At first glance, another digital interface would seem unnecessary with the presence of IEEE1394, Firewire. However, differences between IEEE1394 and DVI make them each suitable for different ap- plications. A comparison of the two interfaces, as applied to home theater, is provided in Table 4.

Simply stated, 1394's bi-directional, compressed data, and AV control capabilities make it suited for recording and networking between various devices. DVI's high speed, full bandwidth capabilities make it most suitable to connect a display device.

IEEE1394	DVI
Bi-directional interface (Record and Playback)	One direction interface (One way to a display)
Networkable between multiple devices	Single point-to-point.
Distributes Compressed Data (MPEG2)	Uncompressed Data (High bit rate HDTV)
Supports A/V Commands (AV/C & HAVi)	No AV Control capability
Copy Protection (5C)	Copy Protection (HDCP)
