  • PAL

    Phase Alternating Line - Modified version of the NTSC TV 
    transmission system used in parts of Europe and other 
    areas of the world.

    PAL was developed as an alternative to NTSC and aimed at 
    reducing the sensitivity of the colour system to certain forms 
    of distortion encountered in transmission and broadcasting 
    when applied to European conditions.
    Countries were divided in their preferences. 
    In 1967 the
    United Kingdom and the Federal Republic of Germany 
    broadcasting using the PAL system while during the same 
    France and the
    Soviet Union introduced colour, adopting 
    another variation to NTSC called SECAM.
    Similar to the other two systems the PAL system is adopted in 
    different countries, however the technical features of equipment 
    are different and PAL products from one country may not be 
    compatible with another country.
    In the UK PAL-I is used with a vision/sound spacing of 6 MHz.
    Other parts of Europe, including the Republic of Ireland, use 
    PAL-B/G with 5.5 MHz spacing.

  • PCB

    Printed Circuit Board - An electronic circuit in which certain 
    components and the connections between them are formed 
    by etching a metallic coating or by electrode position on one 
    or both sides of a thin insulating board. 
    Used globally in a multitude of electrical and electronic 

  • Phono Socket / Phono Plug

    Style of connection used to carry audio or video signals 
    between sound and vision components.

  • Phosphors

    Red, Green and Blue chemical surfaces behind the screen that 
    illuminate when struck by beams from the electron gun within
    CRT TV.

    Phosphors are also within Plasma TV. 

  • PIP

    Picture-in-Picture - Special digital effect where one image is 
    displayed in the corner of a screen during normal viewing.
    Usually the Picture-in-Picture can be positioned in any section 
    of the main picture.

  • Picture Tube

    Main component of a conventional CRT television set that 
    receives the video signal and converts it to a picture. 
    (See CRT - Cathode Ray Tube).

  • Progressive Scanning

    Digital based process used in some NTSC sets to produce a 
    sharper picture. This process scans the picture in one 
    pass rather than producing an interlaced frame from two fields. 
    Common on computer monitors it is also called
    Non-Interlaced Scanning. 

    Originally appeared on an Hitachi 32 inch CRT TV in Europe 
    back in 1998.

  • Projection Television

    There are two basic types which include the single piece rear projection TV and the two piece system which projects an image onto a screen from either the front or rear. Whichever type, they all have their image information displayed on a reflective or
