Additional Information Glossary x Broadband General name for communication lines that use a broad frequency bandwidth for sending and receiving large amounts of video or audio data at high speed. Currently, ADSL, CATV, FTTH and other systems are identified as broadband. x Broadband router For Internet connections through ADSL or a cable TV line, devices called ADSL modems or cable modems are used. However, for Internet access from multiple terminals connected at once, a broadband router is used. x Component video A format for transmitting video signal information consisting of three separate signals: luminance Y, chrominance Pb, and chrominance Pr. High quality pictures, such as DVD video or HDTV pictures, are transmitted more faithfully. The three jacks are colorcoded green, blue, and red. x Composite video A standard format for transmitting video signal information. The luminance signal Y and chrominance signal C are combined and transmitted together. x Crossover frequency The frequency at which two speaker's frequencies intersect. x Deep Color Video signals for which the color depth of signals passing through an HDMI jack have been raised. The number of colors that could be expressed by 1 pixel was 24 bits (16,777,216 colors) with the current HDMI jack. However, the number of colors which can be expressed by 1 pixel will be 36, etc., bits when the receiver corresponds to Deep Color. Since the gradation of the depth of a color can be expressed more finely with more bits, continuous color changes can be more smoothly expressed. x DHCP Abbreviation of Dynamic Host Configuration Protocol. A set of rules to automatically assign settings necessary for network communication. x Digital Concert Hall "Digital Concert Hall" delivers richer sound for 2ch stereo sources such as CDs, etc. With the use of 5.1ch or 7.1ch speakers and virtual speaker technology, stereoscopic reverberation and reflected sound are reproduced, and music software can be enjoyed with richer sound and presence. The sound field in a concert hall is recreated by a geometrical analysis of the concert hall and precise modeling of reflected and reverberant sounds based on actual measured data. Tonal qualities such as sound strength and frequency response are taken into account and calculated on the DSP (Digital Signal Processor) to bring reverberation in. Sound is enjoyed with natural and comfortable resonance, as if listening to music in a concert hall. 180GB
