By Rodolfo La Maestra • Feb 15 2016, 3:00pmThe first article of this series was about audio, this article is about video, the following articles will cover connectivity, not-too-distant-future, Internet and Broadcasting, and the Final thoughts.
Streaming and downloading SD, HD, UHD content with various compression algorithms (MPEG-4, HEVC, VP9, etc.) and various levels of image quality affected by the ISP connection is a concept that is generally accepted by consumers primarily due to convenience; more details are covered in the part-5 article regarding Internet and Broadcasting.
UHDTV started over 3 years ago as...
By Ken Werner • Oct 30 2015, 1:32amIn early October, VIZIO and Dolby Laboratories announced pricing and availability of the VIZIO Reference Series TV sets, which the companies described as “the industry’s first-ever complete High Dynamic Range solution with Dolby Vision™ playback technology.” The series consists initially of two models, one of which you might be if you’ve had a good year, […]
By Rodolfo La Maestra • Sep 24 2012, 2:46pmThere was a recent article by Andrew Robinson of Home Theater Review Magazine about TV calibration that touched a nerve with ISF and THX calibrators.
I actually thought the article was on the spot but Andrew followed it up with a second article that gave a different perspective, not necessarily contradicting the first article, but apparently intended to make peace with calibrators that still had tension on their shoulders even after their massage sessions.
I have a different twist about this subject...
By Shane Sturgeon • Jul 9 2012, 8:46pmThe Consumer Electronics Association (CEA)® today announced five new standards, ranging in topic from accessibility to 3D video to wireless charging, which are now available to guide designers as they develop innovative products for consumers.

By Terry Paullin • Apr 14 2011, 2:14pmReaders of this magazine have long been about examining the best of audio and video ...
...
if not for their own consumption, then just to better understand how various Home Theatre products get to be "the best that they can be".
Regular readers of video product reviews in these pages have come to understand that NO display product can fully realize its potential until it has been calibrated in the environment in which it lives - perhaps your living room.
Clearly, not all display devices calibrate equally well.
There are several factors that impact the end result...

The main features of the new Canon MPEG-2 codec include...
By Ed Milbourn • Jan 12 2010, 4:22pmOne cannot appreciate the enormity of this exhibition except in person.
This was my fortieth CES – the first being in 1965 at the old American Hotel in NYC, called the EIA Convention at that time.
Then as a young engineer with RCA, I was awestruck by two full floors of products – one floor with radio, phonograph and audio tape products and the other with television – mostly black and white models.
Now, the CES occupies several square miles of Las Vegas convention space exhibiting and hosting presentations relative to all types of electronics products competing in the ever hungrier world-wide consumer electronics marketplace.
But one factor remains the same as in 1965: television is the king.
Video products continue to...

By Richard Fisher • Nov 30 2009, 3:55amMotion 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.
For a deeper understanding...
By Rodolfo La Maestra • Nov 25 2009, 5:35pmSeveral 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...
By Rodolfo La Maestra • Nov 24 2009, 5:31pmHigh 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...
By Rodolfo La Maestra • Nov 23 2009, 5:27pmThis 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...

By Ed Milbourn • Aug 5 2009, 3:10pm"Cognitive Radio." What a strange, oblique name for one of the greatest technology advances in telecommunications since Ma Bell decided that ones and zeros made better use of our precious spectrum (over both wired and wireless media) than wavy, wriggly voltage changes.
Clearly, the academics who coined the name failed PR101.
Why not call it "Smart Radio" - because that's what it is - really smart radio.
So, I'll compromise in this wheeze on the subject by cowardly retreating into the technical acronym morass - henceforth tagging "Cognitive Radio" as "COR" and its TV version as "COTV."
The precise definition of COR...
