- - - - Television sets use composite input
      - NTSC television uses a limited color palette and restricted luminance (brightness) levels and black levels
      - While producing a multimedia project, consider whether it will be played on a RGB monitor or a conventional television set
    - - Underscan occurs when computer monitors display a smaller image on picture tube
      - safe title area is where the image will not be affected by overscanning, even in the worst conditions
      - Overscan occurs when an image is larger than the standard TV screen
    - - the electron beam makes two passes on the screen while drawing a single video frame
      - It first lays down all the odd-numbered lines, and then all the even-numbered lines, hence they are interlaced
      - While capturing images from a video signal, they can be filtered through a de-interlacing filter provided by image-editing applications
    - - New tapes should always be fast-forwarded to the end and then rewound, to ensure even tape tension
      - Font for titles should be plain, san serif and bold enough to be easily understood
      - Titles for video productions can be created with an analog character generator
      - Do not kern tightly
  - - - a format for encoding and playing back video files by a computer.
      - includes a player that can recognize and play files created for that format
    - - Streaming audio and video starts playback as soon as enough data has transferred to the user’s computer to sustain this playback
      - Consists
        
        MPEG-4 includes numerous multimedia capabilities and is a preferred standard
        
        MPEG-7 (or Multimedia Content Description Interface) integrates information about motion video elements with their use
        
        MPEG is a real-time video compression algorithm
      - algorithm used to compress (code) a video for delivery
  - - - Quicktime (.mov)
      - Audio Video Interleaved(.avi)
      - Motion Pictures Expert Group (.mpg)
      - Windows Media Video (.wmv)
      - Adobe Flash video (.flv)
  - - - National Television Standards Committee (NTSC)
      - Phase Alternate Line (PAL)
