PAL - (Phase Altering Line standard) - This alternative to NTSC has 625 lines, interlaced, 50 fields per second. It is used in most of Europe, Asia (except USSR), Africa, and Australia, and parts of South America.
PPI (Pixels Per Inch) - Often used interchangeably with DPI, PPI refers to the number of pixels per inch in an image.
Bandwidth - The range of frequencies used to transmit the television signal, including picture and sound. Analog television signals have been allocated at 6 Megahertz for each over-the-air channel. Digital channels are allocated the same 6 Megahertz by Industry Canada. However, by the use of digital compression, a combination of up to 5 SDTV programs and/or one HDTV program can be carried in this 6 MHz digital channel.
Byte - A bundle of data containing eight bits. This is the common size unit for computer data.
VirtualHDT Video Processing Circuitry - Proprietary Hitachi circuitry that digitally upconverts conventional sources to 1,080 progressive lines (twice the display speed of HDTV). This additional picture information enables the processor to make extremely accurate determinations when optimizing the signal to the high-definition capability of the display. Whether it is a DVD, basic cable or satellite channel, or a VCR, VirtualHD 1080p presents the best possible picture regardless of the signal source.
Image Stabilization - Eliminates handshake without degrading picture quality or changing image size.
Digital Television (DTV) - Digital TV is the umbrella term encompassing High-definition Television and several other applications, including Standard Definition Televison, datacasting, multicasting and interactivity.
