Hello All,

Today’s suggestion surrounds utilizing the deinterlace option that is a current function that is readily available within the desktop broadcaster.

Article 1: Introduction Video

What is Deinterlacing?
Wikipedia defines Deinterlacing as the process of converting interlaced video, such as common analog television signals or 1080i format HDTV signals, into a non-interlaced form.
What does this mean in laymen terms? Essentially, standard mediums for delivering and recording video content trick your eye through a phenomenon known as persistence of vision. Images are displayed in rapid succession alternating between different lines of color which change fast enough that your eye cannot differentiate between the two visual fields.

Visual Representation of Interlacing:

Now that we have established what Interlacing is, how can Deinterlacing this image increase the quality of the video one would be streaming through TikiLIVE or any other broadcasting provider? Most standard LCD and Plasma monitors do not run properly in Interlaced Mode which means that the same quality cannot be viewed on a computer monitor as your television set in your living room without a deinterlace filter applied. Please see the following example of the same video that was streamed in the native, interlaced, format as well as a stream with a deinterlace filter applied:

Native Format – Deinterlace not applied:

Adaptive Deinterlace applied:

As you can see applying the deinterlace function makes for a much cleaner frame, particularly along the edge of contrasting colors, such as the white jump suite the gray stripes or black background. The faster the motion the more one will notice that the interlace effects the quality of the image. It is quite clear in the above images that interlace effects the quality of single frames, but what about running video? The following examples are from a recorded session through our TikiLIVE desktop broadcaster with the deinterlace option first disabled and then applied:

Sample Video Source with out Deinterlace applied:

Sample Video with Deinterlace Applied

When viewing the above videos please focus on objects that are in motion, such as the the hands on those who are clapping. In the first video you can clearly see a loss of quality due to the black lines caused by the interlacing of the video. Within the second video these lines have been removed, leaving the viewer with a much more pleasant experience.

When to not use Deinterlace?

Now applying the deinterlace option does not always increase the quality of ones video content. We have two demo feeds on TikiLIVE that do not have the deinterlace option engaged. These feeds are the live webcams from Niagara Falls as well as the Marathon City Marina.

It has been our experience that camera feeds that have many finite details, such as the rushing water of the falls or the glimmer of the sun off the waves in the harbor, actually cause the blending of the images within the deinterlace option to actually decrease the quality. Please see the following examples pulled from the Marathon Marina camera feed:

Marina with Deinterlace off:

Marina with Deinterlace on:

As you can see, applying the deinterlace option to the video feed of the Marathon Marina actually adds to the ‘artificating‘ of the boats, water and dock thus decreasing the video quality.

In summary, the deinterlace option can be easily utilized to increase the quality of your broadcasts, however it must be applied under the right circumstances.

If you have any other questions or comments please feel free to leave them in this blog and I will address them with our next session.

Keep Streaming.
