Apollo 7 slow-scan TV, transmitted by the RCA command module TV camera. NASA decided on initial specifications for TV on the Apollo command module (CM) in 1962. [2] [ Note 1] Both analog and digital transmission techniques were studied, but the early digital systems still used more bandwidth than an analog approach: 20 MHz for the digital system, compared to 500 kHz for the analog system.

Apollo TV camera; Hasselblad "Electric Camera" (modified 500 EL) with 70 mm film; Maurer Data Acquisition Camera (DAC) with 16 mm film; Nikon F with 35 mm film; Mapping (Metric) Camera (7.6 cm focal length) with 127 mm film, on Apollo 15, 16, and 17 (see Sherman Fairchild#Lunar photography) [1]
Roblox is an online game platform and game creation system built around user-generated content and games, [1] [2] officially referred to as "experiences". [3] Games can be created by any user through the platform's game engine, Roblox Studio, [4] and then shared to and played by other players. [1]
English: Video of the Apollo 11 launch, taken from the base of the Launch Umbilical Tower on the Mobile Launcher. Camera E-8 captured this footage on 16 mm film at 500 frames per second. This footage takes place within approximately 30 seconds of real time.
After being tested in public beta since early 2015, [6] Apollo officially launched on the App Store for iOS on 23 October 2017. [7] Halifax-based [8] [9] developer Christian Selig, a former Apple intern, [10] [11] said in his Reddit introduction post that he saw the app as a suitable replacement for Alien Blue, and that the new official app, unlike Apollo, had not incorporated fan-favourite ...
M-JPEG is an intraframe-only compression scheme (compared with the more computationally intensive technique of interframe prediction).Whereas modern interframe video formats, such as MPEG1, MPEG2 and H.264/MPEG-4 AVC, achieve real-world compression ratios of 1:50 or better, M-JPEG's lack of interframe prediction limits its efficiency to 1:20 or lower, depending on the tolerance to spatial ...
The TV is natively only capable of displaying 120 frames per second, and basic motion interpolation which inserts between 1 and 4 new frames between existing ones. Typically the only difference from a "120 Hz" TV in this case is the addition of a strobing backlight , which flickers on and off at 240 Hz, once after every 120 Hz frame.
It can also capture and encode in real-time from various hardware and software sources [35] such as a TV capture card. ffplay is a simple media player utilizing SDL and the FFmpeg libraries. ffprobe is a command-line tool to display media information (text, CSV , XML , JSON ), see also MediaInfo .
