See Figure 1. The control interface can be by one of two means. • IEEE1394/Firewire • Infrared (IR Blaster) The 3rd generation of NetCommand offers additional functionality and a simplier user interface. When using the Firewire, NetCommand is "plugand- play." For the end user, it makes all digital video, audio and control connections with one cable (Figure 2). All other configuration is automatic. For control, the industry standard sofware supported includes: • AV/C - Includes common functions such as Stop, Play, FF, RWD, etc. • HAVi - Includes AV/C but also allows a higher level of sofware communication for a more interactive interface. When using IR, an IR blaster must be connected to the TV and placed in front of the device to be controlled. The TV must then be configured so the proper IR codes will be used. Like previous versions of NetCommand, an "IR Library" is loaded in the TV's software so that most common devices can be selected for immediate use. New for NetCommand 3.0 is the "Learning" feature. For devices that are not included in the IR Library, NetCommand can memorize the IR code from that devices remote. A series of menus walks the customer through the learning process. Once loaded, the TV can then control the device using the IR blaster. This makes NetCommand almost 100% compatable with all other IR controlled devices.

When the user inserts a memory card into any one of the four card reader slots on the front of the set, NetCommand will take control, allowing a slide show or giving a music play list. The memory card formats supported are: • Memory Stick™ • MultiMedia Card™ • SD (Secure Digital) • S...
