  1. What is the standard sample rate for professional broadcast audio?

    Answer: 48 kHz

    48 kHz is the professional broadcast standard audio sample rate, adopted by AES and specified in SMPTE and EBU standards for all broadcast production.

  2. What does the term 'loudness normalization' refer to in broadcast audio, and which standard governs it in the US?

    Answer: Measuring and controlling average perceived loudness to a target level; ATSC A/85 (based on ITU-R BS.1770)

    Loudness normalization targets a consistent perceived loudness level (−24 LKFS for US broadcast per ATSC A/85) so viewers don't experience jarring volume differences between programs and commercials.

  3. What is AES3 (AES/EBU) in broadcast audio?

    Answer: A serial digital audio interface standard for professional audio over balanced XLR cables

    AES3 (AES/EBU) is a serial digital audio interface standard that carries two channels of digital audio over balanced 110-ohm XLR cables at 48 kHz, used throughout professional broadcast facilities.

  4. In broadcast production, what is a character generator (CG) used for?

    Answer: Creating and displaying text, graphics, and lower-third overlays on the video signal

    A character generator creates text overlays such as lower thirds, full-screen titles, weather graphics, and sports scoreboards that are keyed over the video signal.

  5. What is chroma key (green screen / blue screen) compositing used for in broadcast production?

    Answer: Replacing a specific color (usually green or blue) with a different video source

    Chroma key compositing electronically replaces a specific hue (typically green or blue) with another video source, such as a weather map or virtual set background.

  6. What does 'clean feed' mean in a broadcast production environment?

    Answer: A program output without certain local elements such as graphics, commercials, or station IDs

    A clean feed is a version of the program output that omits certain local elements (like local commercials or graphics) and is typically provided to network affiliates or international distributors.
