- Hi Humans,
- When discussing DOGTV, and other television networks, many people tend to ask about the way dogs actually see what’s on the screen. “Can they see it clearly?”, “We heard the screen is flickering” etc. These are great question we receive often, so here’s a short explanation.
When we look at a picture on tv or a film in the cinema, it seems that we’re seeing a complete flowing image, but actually what we’re looking at is lots of individual frames. They seem to flow together because our eyes don’t notice the change between one image to the next. The speed of changing one frame to another is determined by the rate of CFF (Critical Flicker Frequency). For humans, the CFF is around 50-60hz, which means that we are able to see the picture smoothly.
Dogs see the world much faster: their flicker fusion rate may be as high as 70 to 80hz, which means that when they watch an old CRT television, that refreshes at the rate of 50 to 60 hz, they see flickering images instead of continuous motion pictures.
But technology now enables dogs to view and watch television.
With LED, LCD and plasma televisions, the refresh rate is much higher (100 hz and more), which means that digital television enables dogs to see programs the same as you and me. And, after 4+ years of observing dogs watching DOGTV programming, we’re certain they not only see what’s on TV – but they enjoy it, too!
(Weird, but In the UK, apparently dogs enjoy watching “Eastenders”!. go figure..)
