Has some interesting timeline events for audio and video technology.

Anyone want to add anything?

You mean you don't remember me? Back 1999 - 2003, I started and moderated the AVS Tweaks forum and also the AVS Special Guests forum.

Interesting that both Disney and Univeral both sued Sony in the "Betamax Case", yet Disney supports Sony's new format and Universal does not.

When I started the timeline, I was just trying to put together a short, interesting, fun article. However, I found a lot more information than I expected, so I just decided to let it grow.

I'm still trying to get more detailed information about the development of semiconductor based audio electronics, like modern DSP designs. And I'm sure there are a lot of things still missing that are worth including. Please let me know about anything worth adding to the timeline.

And, thanks for pointing out the article.

Curt, if you want to be correct about it - I was the Audio moderator for a bit about March 1999 but quit; they persuaded me to come back and moderate the new Tweaks forum about five months later in 1999; I immediately started the Special Guest feature of that forum; and in 2000 AVS started the Special Guest forum which I moderated as well.

The $20K forum didn't start until I think about 2002!!!

Might be nice if you did what others here in this thread are doing, adding correct info which may be incorporated into the timeline if the author feels its significant. I don't consider the above info that significant except as a retort to your misinformation.

I don't see Nuon technology listed anywhere. This list cannot be considered complete until we at least see some sort of passing reference to this ill-fated DVD techology.

The Advent Video Beam 1000 was the first modern home front projection TV in 1972.

Thanks SuperFrafx and jdonigan. I've created new entries for the projection tv and nuon technology. There was also some interesting information in your Henry Kloss link about the invention of the first acoustic suspension speaker in 1954 that I added to the timeline.

How about revising the 1986 timeline entry to clarify the following therein:

The January 1986 CES sees the introduction of the world’s first audiophile, tube-powered, analog-output-stage CD player, the original CAL Tempest I

Here are a few... DIVX, the original implementation.
Circuit City and some Hollywood studio law firms conspired to make disposable DVDs that only allowed a certain number of days to view once initialized.

At first, Disney movies were ONLY going to be on the DIVX format.

ProScan, RCA and a couple others made "Divx enhanced" DVD players for the first 3-4 years of DVD.

Check out the firsts from Zenith.... First with the remote. Developed the accepted standard for Stereo on FM radio broadcasts... Developed the accepted standard for MTS Stereo on broadcast TV.....

They had about a dozen other major firsts. At one point, Zenith held more HDTV technology patents and drafted more standards contributing to the new format than anyone....
http://www.zenith.com/index.asp?url=...bout_index.asp

Zenith and RCA stuck it out with television manufacturing in the US long after everyone else left. Zenith is now owned by LG, and RCA is now owned by GE....

CABLE TV....

Mark Cuban and the HD Net... HD on mainstream cable and sat would not be where it is today w/out the crazy Billionaire out there subsidizing uber expensive HD rigs traveling around taping anything and everything in HD.

Also, where is satellite in general?? start with the big dish systems...
C band... K band... later (1989?) came Ku band which worked on a then unheard of 36" dish...

How about DSS??
RCA had a one year exclusivity clause on DSS, and the early years had two subsription services, DirecTV (who had the "basic cable" type channels) and USSB (which is where the Premium channels existed) USSB was acquired by DirecTV within a couple years.

Dish Network was launched by Echostar, who were also providers of big dish electrronics.

Prime Star was another DSS competitor, eventually acquired by DirecTV

Also, anyone remember Unity Motion?? (RIP) The original HDTV satellite system....
http://www.businessweek.com/1998/43/b3601011.htm

Voom... (RIP)

Where is the invention of TiVo?? Philips had that sewn up for a year or so before the Sony and Tivo branded units arrived. IMO, this is probably the most important consumer electronics creation involving TV since color.

Speaker technology... Acoustic Research (AR) develops the first acoustic suspension loudspeaker system in 1957 (I believe). This was a breakthrough in reducing cabinet size and creating higher quality low frequency reproduction.

Prior to this, speaker cabinets were very large. ported helmholtz resonator designs, or open back baffles more concerned with aesthetics than adding to the performance.

Another one of the hotly contested tales of hi-fi is who actually invented the commercial in-wall speaker...

Scott Struthers and Geoff Spencer of Sonance claim to have made the first products from old Jack-in-the-Box booth table tops. They were remodeling the stores, and the sheets of material were already laminated!!

The folks at the company now known as Speakercraft were involved to aid in the ramp up in production after the Sonance boys came to the conclusion that they could not meet demand making the speakers by hand in their woodshop.

Speakercraft made Sonance's speakers for years, and then dissolved the partnership and launched their own line of products under the Speakercraft name (which looked surprisingly similar to the Sonance product). The reports are that Speakercraft solicited the dealers and retailers that they had in their shipping logs from the time they made and shipped product for Sonance.

Bang and Olefsen and Audio Design Associates (ada) both have rights to lay claim to the first residential multi-zone audio systems produced.

While it is not clear who's product was out first, both manufacturers had systems available in the mid/late 1980s.

Thanks Cinemascope for all the info. I've added lots of Zenith history to the timeline as well as some significant milestones for CATV, LCD and DLP technology, the satellite industry and TiVo.

I already included information about AR's acoustic suspension speakers in 1954. I'll look into the commercial in-wall speaker controversy and the multi-zone audio systems. I also want to add something about CableCard.

Thanks for catching that. My original source was from the Audio Engineering Societies website - An Audio Timeline. It looks like several of my other sources confirm the information you found on Wikipedia.

Was this a first? I can't find any information other than this from Sony -

Dec. 1990 - Launch of the HD-equipped, 16:9 wide aspect ratio, 36-inch consumer-use television, the KW-3600HD.

When they list other accomplishments, they usually say if it was the World's first or Japan's first. In this case, it just says the product was launched. It also doesn't mention analog, but I assume that would be the case. It was probably based on the MUSE system.

I believe it was first to the U.S., anyway. I remember that duo being available for rent from a particular agency advertised in American Cinematographer magazine. That was back in either '88 or '89.

1982- RCA releases their stylus-enabled Selectavision CED player. Music, movies and video are played from a vinyl disc. A japanese company (I forget which) releases a similar but incompatible format in response.



1983- HBO's signal is hacked (and tagged by a 'Captain Midnight'), prompting the adoption of encrypting satellite signals. I'm unsure who gets credit for creating satellite encryption technology.
