HDMI Part 8 - Cables for 1.3

By Rodolfo La Maestra • Aug 29 2006, 2:39pm

Now this is a sensitive area, isn't it?

The purpose of this article is NOT to justify or reject the concept of spending a dollar more for "claimed" cable quality while other people rather want to save that dollar any time the term cable is mentioned.

People take all kinds of corners on this matter, and many confrontations still happen with or without blind tests, with or without factual data.

HDMI Part 7 - Type A and B Connectors (Did You Know a Type B Existed?)

By Rodolfo La Maestra • Aug 22 2006, 2:38pm

There are several TVs that already support 1080p60 on HDMI (using Type A) and there are quite a few other video processors, projectors, etc. that have been out for years that support 1080p60 on HDMI (Type A). 1080p60 was supported since HDMI 1.0.

There are no products with Type B connectors, and there is no relationship between 1080p60 (148.5MHz speed) and Type B. None of the Primary or Secondary formats...

HD DVD vs. Blu-ray: And the Winner is ... No One

By Shane Sturgeon • Aug 16 2006, 6:43pm

By now, I'm sure you've read a dozen articles like this one. In fact, I debated about whether or not to title it as such, as I was afraid most of you would skip it over. Obviously that is not the case if you are now reading these words.

If you are withholding your Next-Gen DVD player purchase until this so-called format war has a winner, it won't help ... there likely won't be one ... and there definitely won't be one any time soon.

HDMI Part 6 - 1080p Support

By Rodolfo La Maestra • Aug 15 2006, 2:00pm

Although the 1080p capability exists since version 1.0, 1080p is not mandatory in the HDMI spec, in any of the versions.

It would be difficult for Silicon Image to require TV makers (especially those with non-SiI chips) to indicate the chip's 1080p feature to end-users. It is not too different from how consumers know whether their component analog input can handle 1080i, 720p, or 480p. It was not too long ago that 100% of component inputs handle 480i only. Then shortly after that there was 480i and 480p, etc.

HDMI Part 5 - Audio in HDMI Versions

By Rodolfo La Maestra • Aug 8 2006, 12:19pm

HDMIWhile the multichannel audio industry keeps creating more formats for newer equipment, it also creates the need of compatibility with existing equipment. And being the digital connectivity solution that the industry says it is, HDMI has to meet the challenge of that "evolution".

When HDMI 1.1 came out, it added to the spec a new packet to carry some DVD-Audio content protection-related data. All audio capabilities of DVD-Audio were part of 1.0 but the CPPM/CPRM license (used for DVD-Audio encrypted disks) required some additional data to be transmitted.

Then, when HDMI 1.2 came out...

HDMI Part 4 - 1.3 Backward Compatible with non-1.3 Equipment? How?

By Rodolfo La Maestra • Aug 3 2006, 6:32pm

This part concentrates on the video capability of 1.3 for backward compatibility; multichannel audio capability is covered in Part 5, the next article in this series.

As mentioned before, version 1.3 adds the capability of 30-bit, 36-bit, and 48-bit pixels, which in 4:4:4 (the primarily target) means 10-bit, 12-bit, and 16-bit per component...
