For me, ATSC HD today is every bit as much of a jaw dropper as the first time I saw color TV in 1957.
I believe HDTV parallels the early days of NTSC color in this way— the technology behind the picture is amazing and awe inspiring. The same six megahertz of NTSC bandwidth that found space for chroma information in 1953 now contains an ATSC 1080i, 16x9 video with five discrete full-bandwidth audio channels plus a subwoofer channel. In the first NTSC color sets, the bandwidth of their video amplifiers was about 3-MHz, and the picture looks good. In an ATSC HD set, the video-amplifier bandwidth is about ten times as much as a CT-100.
There are a lot of variables, and television manufacturer’s shuffle designs to fit marketing strategy. But when you view high-definition video generated with the best HD cameras on a CRT with a dot pitch fine enough to reproduce what the system can deliver, for me it’s worth looking at even though the content doesn’t always measure up to the technology.
As for the behind-the-scenes developers of analog color television: These are some of the companies who contributed to the 1953 NTSC color television standard.
• American Telephone and Telegraph Corporation
• Farnsworth Television and Radio Corporation
• General Electric Company
• Hazeltine Research, Inc.
• N. V. Phillips’ Gloeilanpamfabricken
• Philco Corporation
• Westinghouse Electric Corporation
It’s a list that was compiled by RCA and appears on a label inside the cabinet of every CT-100 made.
Here’s a link to a page on my CT-100 site discussing the Hazeltine and Philco contributions to NTSC color television.
