HOME THEATER'S AV GLOSSARY

H

  • Hanging Dots: An artifact of composite video signals that appears as a stationary, zipper-like, horizontal border between colors.
  • HDCP: High-Bandwidth Digital Content Protection. Created by Intel, HDCP is used with HDTV signals over DVI and HDMI connections and on D-Theater D-VHS recordings to prevent unauthorized duplication of copyright material.
  • HDR: Hard-Drive Recorder. Device that uses a computer hard drive to store compressed digital audio and video signals.
  • HDMI: HDTV connection format using a DVI interface that transfers uncompressed digital video with HDCP copy protection and multichannel audio.
  • HDTV: High-Definition Television. The high-resolution subset of our DTV system. The FCC has no official definition for HDTV. The ATSC defines HDTV as a 16:9 image with twice the horizontal and vertical resolution of our existing system, accompanied by 5.1 channels of Dolby Digital audio. The CEA defines HDTV as an image with 720 progressive or 1080 interlaced active (top to bottom) scan lines. 1280:720p and 1920:1080i are typically accepted as high-definition scan rates.
  • Hi-Fi Stereo: Feature found on VCRs that records or plays back stereo soundtracks with improved fidelity compared to using the linear stereo tracks.
  • High Gain Screen: Material that reflects more light than a reference material. Increases a projector's light output at the expense of uniformity.
  • High Pass: A filter that passes high frequencies, and attenuates low frequencies. Same as low cut.
  • Home Theater in a Box: A complete home theater system in one box (or at least sold together as a package). Consists of five or more speakers, a subwoofer, and a receiver. May also include a DVD player.
  • Horn: A type of speaker that looks like a horn. These speakers have small drivers and very large mouths; the horn shape serves to transform the small radiating area of the driver into the much larger radiating area of the mouth of the horn.
  • Hz: Hertz or cycles per second. Something that repeats a cycle once each second moves at a rate of 1 Hz.
