Our Newest Sponsor

May 13th, 2012

 

Thomson Broadcast has become TheOnLineEngineer’s newest and most generous sponsor. I want to thank all the people who have sent in donations over the last three years, but in particular I want to thank the two biggest contributors, SBE Chapter 38 in El Paso, Texas and their Chairman Antonio Castor and now Thomson Broadcast and Richard Fiore and Joe Turbolski who have jut given us our largest donation to date.

You may have noticed that I have mentioned their transmitters more so than any other, that’s because over the last 14 years I have worked with eight different Thomson transmitters, from analog IOXs to digital DCX Millenniums and their MSDC Paragons. You write about what you know.

These contributions will help in running and expanding TheOnLineEngineer to further educate Broadcast Engineers around the world.

Thank you

Fiber Optic Tutorial is Coming Along

May 13th, 2012

I am putting a lot of effort into this next tutorial which is all about Fiber Optics for Broadcast. But it is taking much longer than usual as I have high hopes to make this a really great tutorial. In the mean time while I work on it here is a sneak preview.

The sound effect were added later, fusion splicers don’t really sound like that, but it seemed like a fun thing to do.

TheOLE iPhone App Wish List

April 29th, 2012

TheOLE App

TheOnLineEngineer’s Handy Reference
for Broadcast Professionals

I am working on developing a Broadcasters App for the iPhone and iPad. The idea comes from the Blonder & Tongue Broadband Reference Guide book, but without all the Blonder & Tongue equipment stuff. Now I have my own ideas for what should go into it but I thought it would be great to hear from you, the readers of TheOnLineEngineer as to what you would want in a handy guide that you could carry around in your pocket.

So what do you want to see included in our “TheOnLineEngineer’s Handy Reference for Broadcast Professionals”?

So far I have; Formulas, Frequencies,Fiber Optics,Digital Video,Digital Audio, Connectors,RF, IP Communications,Wire and Cable, Company Contacts and My Notes where you can write down your own notes.

What Have I missed?

What would be useful to you????

Be as specific or vague as you like, I will try to fit in as many suggestions as I can.

I hope to have it working by the end of June.

History of HDTV (part four)

March 30th, 2012

This is the fourth installment of Philip J Cianci’s book “High Definition Television – The Creation, Development and Implementation of HDTV Technology”. This book provides a comprehensive look at how we got to where we are today with HDTV. Starting back in the mid 60’s in Japan through the Grand Alliance to today’s global deployment of HDTV, you get an inside view of what went on.

It’s a fascinating story that’s well told.

Phil has made arrangements for TheOnLineEngineer to publish excerpts from his book over the next several weeks. This is the excerpt from Chapter 4.

The book is available from Amazon and a list of links to international booksellers can found on Phil’s website – www.HDTVarchiveproject.com.

 

Chapter 4

“America’s International Competition”

At the third U.S. House of Representatives Telecommunications Subcommittee hearing on HDTV in September 1988, Chairman Markey asked the EIA, the AEA, the Semiconductor Industry Association (SIA), ACATS and the NTIA to submit action memos with concrete proposals by January 4 on what the federal government could do “to insure an American presence in the development and manufacture of advanced television technology, related componentry and derivative products.” The subcommittee arranged HDTV system demonstrations on Capitol Hill by Sarnoff, Del Rey Group, Faroudja, NYIT, NHK, Philips and Zenith in the Cannon House Office Building caucus room. Simultaneously, the FCC issued an NOI (Notice of Inquiry) calling for submission of ATV proposals to ACATS. Fifteen organizations responded. (Table 4-1.)

In the U.S. theater of operations, Sarnoff, Zenith, AT&T and North American Philips squared off against each other and NHK. A few smaller efforts entered the fray. Del Rey Group, with financing from Cox Enterprises and Tribune Broadcasting, developed a digital NTSC-compatible system. Dr. William Glenn’s work was supported by NYIT (Sims 9/21/88). Quanticon submitted a video-only proposal. Two audio proposals for ATV, one from Dolby the other from Digideck, would also be tested. Philips’s entry was developed independently by its U.S. lab, while Sarnoff received funding from Thomson; both were sometimes characterized as “foreign” ATV proponents and characterized, along with NHK, as threats to American interests.

Events and topics discussed in this chapter include:

  • ACATS vets 21 ATV proposals during Hell Week
  • ANSI acceptance of SMPTE 240M
  • Square Pixels
  • NASA’s initial HDTV evaluations
  • Nine systems are scheduled for ATTC testing (includes block diagrams)
  • General Instrument submits an all-digital HDTV system to ACATS

and more…

History of HDTV (part three)

Starting back in the mid 60’s in Japan through the Grand Alliance to today’s global deployment of HDTV, you get an inside view of what went on.

Chapter 3

“Techno- Industrial War”

The failure at Dubrovnik to establish a world television standard was not without precedent. On more than one occasion the European television community rejected NTSC, with the intent of protecting regional manufacturing. Nevertheless, encouraged by the success of the CCIR 601/SMPTE 125 digital interface and a new spirit of global technical cooperation, an industry consensus regarding HDTV parameters was beginning to coalesce: image quality equivalent to 35mm release prints, i.e. at least twice the resolution of current television systems, and a display aspect ratio of 16 x 9.

 

Anxious to get started with this new medium of artistic expression, some European broadcasters opted to temporarily use the 1125i60 Hz based production system, even if they opposed a 60 Hz format (Bögels, p. 4). But this did not imply capitulation to Japan Inc.’s latest technological invasion; Europe staunchly refused to allow the Japanese to continue to destroy professional broadcast and consumer electronics industries by establishing “screwdriver plants.”

 

During the CCIR Dubrovnik Plenary, European delegates decided to use the MAC 50 Hz system for analog and HDTV satellite transmission. In need of some form of economic stimulus as inflation was rising at about 4 percent per year, at its June 30 London meeting, the European Economic Community announced the launching of the Eureka-95 Project; an expansion of an alliance between Philips, Bosch, Thomson and Thorn-EMI. With funding primarily from member companies, “Eureka Project 95” (“Eureka-95,” “E!95” or “EU95”) would develop HDTV standards and production, transmission, display and recording equipment. Philips was the project’s main sponsor and directed efforts in the Netherlands; Thomson in France; Broadcast Television Systems (BTS), Philips’s partnership with Grundig, would manage activity in Germany. European-bred HDTV would turn back the Japanese economic assault.

 

Events and topics discussed in this chapter include:

 

  • EUREKA-95 and HD-MAC
  • MST and NAB Congressional HDTV demos and FCC Advanced Television Petition
  • Formation of the Advisory Committee on Advanced Television (ACATS)
  • The first independent HDTV production houses
  • Development of SMPTE 240M and tri-level sync
  • Establishment of the Advanced Television Test Center (ATTC)
  • NHK’s Seoul Olympics HDTV broadcasts, EUREKA-95’s IBC ’88 demonstration

The History of HDTV (part two)

Chapter 2

“Road Blocked”

With a single HDTV proposal before the CCIR, it appeared that the next generation of television would be globally unified in a single production standard. This would eliminate format conversion and facilitate the highest possible image quality for international program distribution. An additional benefit was a reduction in redistribution costs due to a streamlined workflow; with a thriving program export business, this could potentially improve a U.S. television content producer’s bottom line.

Following SMPTE in San Francisco, CBS conducted two days of HDTV feasibility demonstrations at WUSA, its Washington, D.C. affiliate, attempting to influence the FCC to reserve DBS frequencies for HDTV. In February, CCIR SG11 held its final meeting and released Report 801, “The Present State of High Definition Television,” describing an 1125-line, 60 Hz, 2:1 interlaced system, essentially the NHK parameters.

Although compression work by CBS had achieved 4:1 bit reduction of NTSC video using a data reduction technique—Phase Alternating Sub- Sampling (PASS)—developed for DBS systems, Joe Flaherty was convinced that without higher compression ratios, HDTV would never be broadcastable (Free). WARC planned to allocate the 12 GHz band at its1983 meeting, but CBS was anxious to investigate satellite transmission, and in July requested FCC permission to implement an experimental HDTV satellite system using three channels in the 12 GHz band on COMSAT. Meanwhile, Flaherty enthusiastically promoted HDTV and moderated an SMPTE panel discussion on “High-Definition Television: How, Why and When” in New York in September.

Events and topics discussed in this chapter include:

  • CBS HDTV research, content production and demonstrations
  • Formation of the Advance Television Systems Committee (ATSC)
  • The EBU and Europe’s first HDTV efforts and demonstration
  • CCIR 601 and SMPTE 125M
  • 16 x 9 aspect ratio
  • NHK’s MUSE DBS system
  • The CCIR’s XVI Plenary Assembly in Dubrovnik, Yugoslavia

A Lens for your iPhone

February 13th, 2012

I was in the Apple store the other day when I came across this item. It’s called the OLLOClip, it’s a lens adapter for the iPhone 4 giving you a Fisheye lens

 

 

 

 

and a Wide Angle lens

 

 

 

And a Macro Lens all in one package.

 

This comes from the label on an old MacBook Pro Hard Drive, take a look at the normal view.

 

What I like about it is it’s small package, that I can carry it around, in it’s little bag, and just pop it on anytime I need it.

 

I will be doing some experiments with OlloClip soon.
