The Tech Behind a CES Keynote

This year, Qualcomm's own Paul Jacobs took the stage to kick off one of the world's biggest tradeshows, CES. But what type of technology does it take to pull off a speech of keynote caliber? Check out Spark’s top tech behind the speech.

6. The main screen used for CES keynotes is 50 feet wide, about the size of a movie theater display. To fill it, you need graphics 3,500 x 1,050 pixels.

5. On either side of the main screen are two smaller screens, each around 18-feet wide. The side screens require graphics of 720 x 1,280 pixels, which is about the same resolution as an HDTV hung vertically.

4. When the two side screens and the main screen display the same image, it will require graphics 6,060 x 2,490 to fill the giant, 86-foot wide display.

3. Rendering graphics for the huge screens takes a powerful server farm – and a lot of time. It takes almost a week to complete a full render (including test and final versions). 

2. During the show, operators use a program called Dataon Watchout to manage the huge feed, and control what goes on the different screens.

1. The finished movie is nearly 1 Terabyte in size. That’s more than 40 times more data than what’s on a single layer Blu-Ray disk.
