Ed's View - Keeping Honest People Honest

By Ed Milbourn • Jun 23 2005, 12:36am

In April 1803, President Thomas Jefferson gave Meiwether Lewis (of the Lewis and Clark Expedition fame) a rather sophisticated key-based cipher table. This table was to be used to encrypt messages intended for the President in Washington if those messages would be sent via a foreign carrier, such as a foreign ship, when the expedition reached the Pacific Ocean. But, alas, the cipher table was never used as no ships came while the expedition was camped there. The point of this anecdote is that the concept of encrypted messages for security and content protection reasons is not new. In fact, language encryption has been around as long as man has been literate (about 10,000 years). It has been surmised that encoding words and speech is one of the reasons different languages developed. May be, but one thing is common with all of the various encrypting schemes through the ages - they all have been broken, no matter how sophisticated.


Ed's View - Sound

By Ed Milbourn • Jun 22 2005, 4:16pm

This is the fourth in a series of articles by renowned veteran television designer, Ed Milbourn. These articles are designed for the novice investigator of the DTV/HDTV transition.

Ed's view


It is amazing to me how much the quality of HDTV sound production has advanced in the past couple of years. Almost all of the film based HDTV programs, i.e. most of the prime time fare, make full use of ATSC Dolby Surround sound encoding. Also, many of the live productions now include audio using all six channels of Dolby Surround. That is in addition to most movies shown in HDTV as will as on DVD's and Cable/Satellite PPV offerings.

The Politics of the Transition to DTV - Jeff Hart

By Dale Cripps • Jun 20 2005, 10:52pm

The transition to digital television (DTV) is occurring in all the major industrialized countries and in a selected number of developing nations. I will focus today on the transition in the United States as well as discuss the experience of other countries where that helps us to understand the choices available.

Here are the key policy issues in making the transition:

- subsidizing poor and elderly consumers so that the analog broadcasts can be turned off (thus freeing spectrum for other uses);

- working out the relationships between over-the-air broadcasters on one hand and cable and satellite service providers on the other via "must carry" rules in a fair and equitable manner;

- allowing consumers to purchase add-on services without being forced to purchase unnecessary equipment from service providers ("plug and play");

- protecting the intellectual property rights of content producers w ...

Ed's View - The Best HDTV Display

By Ed Milbourn • Jun 14 2005, 4:30pm

After the meeting, we were whisked back to a room deep in the bowels of the labs by one of the developmental engineers. He said he wanted to show us what color television could do if there were virtually no technical limitations. Just before entering the room, he said, in a matter-of-fact tone, "You will never see images reproduced better than this." Well, never is a long time, but to date, he was right.


Ed's View - Are We Being Ripped Off?

By Ed Milbourn • Jun 11 2005, 7:18pm

So,the subject has piqued your curiosity, as it should. For, as HDTV grows, we must act as "policemen" to stem attempts to compromise quality. To be sure there are, and will be, many different quality levels due to production variances, HDTV production equipment limitations, and the effect of the production "learning curve." As production experience is gained and equipment improves, the quality will only get better. However, the question remains whether this positive production improvement curve will be, or indeed is being, compromised at the transmission end - regardless of the physical "transmission" mode - OTA broadcast, cable, DBS, etc. Probably not, but again it depends. Why?
