HD Waveform - Vertical and Horizontal Filtering

By Richard Fisher • Aug 1, 2:23am

While rarely mentioned over the decades, vertical filtering, which removes horizontal detail in your image, has been around as long as CRT has and is still used to this day in displays and source scaling. Even with the arrival of DTV in 1998, vertical filtering was commonly used in the video circuits of consumer 1080i HDTV CRT displays. For this article we are looking at vertical or horizontal filtering related to luminance response.

The first step with horizontal and vertical filtering is...

Ed's View - Will Your Favorite TV Channel Disappear on Feb. 17th?

By Ed Milbourn • Jun 19, 4:38pm

So far, practically all the digital transition "buzz" has been focused on avoiding the trauma that would be suffered by the "poor little old ladies" vainly wiggling their rabbit ears atop their 1975 Zeniths and getting no picture (or sound) on February 17, 2009.

Yes, I'm sure there will be a few of those. But there will be a lot more, and very vocal, "little old ladies" who already have digital reception capability (HDTV or otherwise) who will be shocked on Feb. 17th to find out they are not receiving one of there favorite DTV channels, and many...

High Definition Movies Before They Hit Blu-ray? Only if Your HDTV Permits It.

By Rodolfo La Maestra • Jun 17, 11:32am

How would you like to view an HD movie at home via Video-On-Demand (VOD) just a few weeks after its theatrical release, even before it's released on DVD and Blu-ray? Maybe your HDTV connections would not let you do it, despite the fact that you paid for the movie.

On May 9, 2008, the MPAA issued a petition to the FCC for a waiver of the SOC feature...

CRT Rear Projection and Direct View Service and Repair

By Richard Fisher • Jun 12, 7:32pm

The infamous CRT rear projector, whether NTSC or HDTV, remains one of the greatest display products to have hit the consumer market. They lasted over two decades until the flat panel display phenomenon wiped them out. The same can be said of CRT direct view, the TVs we all grew up on. While big, bulky and heavy, these displays could deliver some great imaging, producing bright dynamic pictures and inky blacks in medium to dark ambient light environments. For rear projection, smaller sizes (below 50") could even perform well in brighter environments. CRT rear projection and direct view technology was used to drive the HDTV revolution out of the gate and along the way there were some really stellar videophile performers meeting most of the imaging science aspects of video standards. These products have a typical 10-15 year life span based on normal usage and CRT wear and tear. Before deciding to throw out this technology, you should reflect on the imaging performance you will be losing, ...

Sony KDL-46XBR4 46 inch LCD HDTV

By The HT Guys • May 20, 4:23pm

The TV looks visually appealing and has a high build quality. There is a clear plastic frame that goes around the TV. The TV weighs 84 pounds (38 Kg) with the pedestal and measures 49.7" (126 cm) wide by 31.3" (79.5 cm) high by 17.7" (32 cm) deep (4.8" (12 cm) without the pedestal). We immediately took the TV off the default setting and changed it to cinema. Cox cable looked very bad. So bad that we recommended switching to satellite. Braden has Cox as one of his sources so his impression was that Cox does not look that bad on his TVs. It could be that this TV does not do well with compressed sources. OTA HD looked much better. In general OTA digital channels looked better than the SD coming from the Cox cable box.

We then popped in a Blu-ray disc...

Home Theater Concepts: Is a 1440x1080 HD Camcorder Inferior to a 1920x1080 HD Camcorder?

By Robert A. Fowkes • May 16, 4:08pm

The question has been raised regarding how good 1440x1080 resolution from HD camcorders is when compared to "full" 1920x1080 resolution devices. While it is technically accurate to say that 1920x1080 images contain more pixels than 1440x1080 images the actual appearance to the native eye is not as different as logic might make you think. And the choice of "1440" as the resolution in the horizontal direction in a "1920x1080" world is not an arbitrary number but carefully selected due to
