In the Trinitron design, the problem was greatly simplified, [how?] requiring changes only for large screen sizes, and only on a line-by-line basis. For this reason, Trinitron systems are easier to focus than shadow masks, and generally had a sharper image. [citation needed] This was a major selling point of the Trinitron design for much of its ...
Super Fine Pitch tubes naturally fall into this category, as do some Sony Trinitron SDTVs that cannot physically resolve 1080 lines of vertical resolution, but the term Hi-Scan is commonly used to refer to Sony Trinitron HDTVs that do not feature an SFP tube. 16:9 Enhanced WEGA models differ from original WEGA models mainly in their ability to ...
U-matic, with its ease of use, quickly made other consumer videotape systems obsolete in Japan and North America, where U-matic VCRs were widely used by television newsrooms (Sony BVU-150 and Trinitron DXC 1810 video camera), schools, and businesses.
The system was dim, complex, large, power hungry and expensive for all these reasons, but provided a usable color image, and most importantly, was compatible with existing B&W signals. This had not been an issue in 1948 when the first FCC meetings were held, but by 1953 the number of B&W sets had exploded; there was no longer any way they could ...
The quality of the design by Esslinger was highly appreciated, to the extent that the Museum of Modern Art in New York [10] exhibits one example, the Concept 51k sound-system, for which a special stand was an available option. [11] In 1980 Sony used half of the production in Stuttgart for its Trinitron televisions. [12] [13]
The PAL-L (Phase Alternating Line with CCIR System L broadcast system) standard uses the same video system as PAL-B/G/H (625 lines, 50 Hz field rate, 15.625 kHz line rate), but with a larger 6 MHz video bandwidth rather than 5.5 MHz and moving the audio subcarrier to 6.5 MHz. An 8 MHz channel spacing is used for PAL-L, to maintain compatibility ...
Sunstein produced a prototype Uniray system using an original Philco tube and new electronics, and started shopping the concept around in 1972. There was some effort to license the system to Japanese companies, most of whom had licensed the shadow mask from RCA and were facing stiff competition from Sony's newly introduced Trinitron system.

Zenith was the first company to experiment with subscription television, launching their Phonevision system with experimental Chicago station KS2XBS (originally broadcasting on Channel 2 before the Federal Communications Commission forced them to relinquish it to WBBM-TV). Their experiment involved a descrambler box mounted on the television ...
