Broadcast Leader Elements

September 1, 2015
Broadcast Leader Elements

Television stations will provide detailed instructions of their broadcast requirements for producers to follow prior to submitting their program. However, before exploring the technical specifications of the bit rate, codec, wrapper, GOP structure, etc. you’ll need to make sure you add your broadcast leader elements to your timeline. Although the requirement varies from station to station (and is sometimes absent), we have established a common layout of how the leader elements should be formatted.

  • 60 seconds of color bars & tone
  • 10 seconds of black slug
  • 10 seconds of slate
  • 10 second universal countdown (standard countdown that goes to black with 2 seconds left)
  • FADE IN

NOTE: Always confirm the requirements with the station’s guidelines and stay consistent if you are a weekly program – stations may automate the trim of your leader & tail elements prior to air.

Color Bars & Tone

Color bars, or color television test pattern, is a computer-generated electronic signal produced by a camera or editing software. The color bars (examples shown below) are accompanied by a 1kHz (-20dBFS) audio tone.

Traditional SMPTE Color Bars
Modern HD SMPTE color bars feature a grey-scale gradient

Whenever possible, it is best to originate the color bars from the capture equipment (video & audio). However, they’re readily available in your editing software.

Slate

Your slate tells the station’s traffic department everything they need to know about your program. Our recommended layout is as follows:

  • Client Name
  • Show Title
  • Episode (ISCI Code)
  • Episode Title
  • TRT: (program total run-time from FADE IN to black - without the leader & tail elements elements)
  • Closed Captioned (if applicable)
  • Contact Name
  • Contact Phone Number

Universal Countdown                

A continuous countdown from eight to two with the numbers in the center of a target with two white circles and a rotating "clock arm" animation. At two, a quick 1 kHz audio beep is heard, also known as the 2-pop. After the end of the countdown, FADE IN to the start of your program.

A “tail” element was also mentioned, wasn’t it? It is recommended to add five to fifteen seconds of black slug to your program. Again, confirm with your stations and stay consistent.

That’s where Aberdeen will run the race for you. Our AberFast Digital File Delivery service coordinates with your station distribution list to ensure that you are formatting your content to their specific technical specifications and get it right every time.
