MediaTech: TV Tech: The Evolution of TV (W11-P3) [VID] Fa16

We've covered a variety of theories that explain the development and diffusion of media technologies (e.g. diffusion and technological determinism).  Let's now start to add another to our list.  Let's start to look at how technologies evolve.  Are there similarities between the biological theory of evolution and technological theory of evolution?

First, briefly what is the theory of evolution and how might it be applied to the evolution of media technologies, like TV?  




How has TV evolved?  When watching this what changes do you spot?  What features change?
Is it helpful to think of media technology evolving?

Along with Winston's model, Diffusion of Innovations, etc., we've now added the evolution of tech as another theory that helps explain how and why media tech develops and spreads throughout society.  We'll cover a little more on this theoretical perspective a little later.

MediaTech: TV Tech: How HDTV Works (W11-P3) [VID] Fa16

Now let's move to HDTV and answer such questions like what's that 1080 stuff?



Nowadays, you don't need a separate receiver.





The newest TV tech out there is UHDTV.

Ultra-high-definition television (also known as Ultra HD television or UHDTV) includes two types (1) 4K UHD (3840 pixels wide by 2160 pixels tall or 8.3 megapixels) and 8K UHD (7680 pixels wide by 4320 pixels tall or 33.2 megapixels).

MediaTech: TV/Radio Tech (Basics): How Radio Works (W7-P2) Fa16

Before talking about how radio works, it is first helpful to understand the electromagnetic spectrum.  What is the electromagnetic spectrum?




Now, how does radio fit into this?  What does it have to do with the spectrum?  The following video provides a good overview.




Now some detail from decades ago. While the specific tech shown is from decades ago, the basic principles still apply today. Spot the steps in signal processing?




For a quick summary on how radio works, see this quick video below.  What new pieces of info are added here?

Pixels and Persistence of Vision

"One time I tried to take a picture of my favorite television show and the photo only showed about a quarter of the picture on the screen. Why did that happen?"   Read the rest on this web page. See the interactive graphics as well.

Black and White TV Screens

"We keep talking about these little dots. What are they made of, anyway?"  Read the rest on this web page.  See the interactive graphics as well.

Bright and Dark

"Now I have two more questions! First, how does the electron beam move around to different parts of the screen? And second, how do you get gray pictures out of light and dark phosphors?"  Read the rest on this web page.  See the interactive graphics as well.
