Motion flow processing has played a huge role in the marketing of LCD product, turning what used to be negative into an unnecessary marketing positive.
At first it was 120 Hz processing and now the big hype is 240 Hz processing; bigger numbers infer better.
The common misperception is that motion flow processing is all about compensating for LCD pixel speed when actually the main purpose is to remove the potentially objectionable strobe effect of 30 and 24 frame content that appears most strongly with high contrast displays, like an LCD.
All displays suffer from this artifact to some degree with contrast ratio playing the greatest role.

Several formats were introduced over the past few years to distribute pre-recorded HD content.
Some of those are already discontinued; others were introduced at trade shows in the US (such as the Consumer Electronics Show, CES) but were implemented only overseas.
Pre-recorded HD content was available in the form of digital D-VHS videotapes before Blu-ray was established.
The tapes were...

High quality HDTV can be broadcasted using the 6 MHz channel-slot of one analog NTSC channel, but with over 9 times its resolution quality.
The NTSC image is made of 480ix450 viewable picture elements per video frame composed of two interlaced fields and delivered at a rate of 60 fields (30 frames) per second.
Most HD broadcast compressed with MPEG-2 is transmitted as interlaced 1080i with 2 million+ pixels per video frame (1080x1920 pixels), each frame is composed of two interlaced 540-line fields delivered at the rate of 60 fields per second (30 frames).
Some HD broadcasts use...

This series of three articles analyzes the current and future market for HD, the methods of distribution and the capabilities of the digital technology to distribute HD content to meet consumer expectations.
This technology must also support other quantity oriented businesses and services that can potentially degrade the original HD vision and affect those that invested in HDTV equipment under the reasonable expectation of viewing uncompromised HD quality, not just digital.
This is a dilemma of quantity vs.
quality when DTV permits the implementation of both, sharing the same bandwidth.
HD content is defined in this article as...

Ah, flat screen TV … just what so many were waiting for to put on the wall, mostly inspired by Hollywood and television programs over the decades.
Yep, putting that flat screen on your wall is the Buck Rogers thing to do for so many of us.
What most people don’t know is that by doing so you have made yourself responsible for additional services and charges if the product fails.
All service programs...

The subject of “content protection” continues to be a complicated issue.
While some firmly think that one should be able to legally make a copy of lawfully acquired content, if such content is protected to avoid exactly that and the protection is circumvented to perform such copy, how can that action be right when it is actually violating the right of the content creator?
The content production industry needs...
