At that time, the ENIAC was considered to be the first computer in the modern sense, but in 1973 a U. S. District Court invalidated the ENIAC patent and concluded that the ENIAC inventors had derived the subject matter of the electronic digital computer from Atanasoff ( see Patent dispute ).

Starting in the late 1970s to the early 1980s, several types of video production equipment were introduced, such as time base correctors ( TBC ) and digital video effects ( DVE ) units ( one of the former being the Thomson-CSF 9100 Digital Video Processor, an internally all-digital full-frame TBC introduced in 1980, and two of the latter being the Ampex ADO, and the Nippon Electric Corporation ( NEC ) DVE ).

It was clear by that point in time that HDTV did not provide a sufficient technological basis for the foundation of digital cinema playback.

Applications of electronic visual displays include electronic pricing labels in retail shops, and digital signage, time tables at bus stations, electronic billboards ,< ref >

Most filters implemented in analog electronics, in digital signal processing, or in mechanical systems are classified as causal, time invariant, and linear.

Very different mathematical treatments apply to the design of filters termed infinite impulse response ( IIR ) filters, characteristic of mechanical and analog electronics systems, and finite impulse response ( FIR ) filters, which can be implemented by discrete time systems such as computers ( then termed digital signal processing ).

Although a digital filter can be an IIR filter if the algorithm implementing it includes feedback, it is also possible to easily implement a filter whose impulse truly goes to zero after N time steps ; this is called a finite impulse response ( FIR ) filter.

Thus the complexity of a digital filter and the computing time involved, grows inversely with, placing a higher cost on filter functions which better approximate the desired behavior.

Using transforms it is possible to convert these continuous time frequency responses to ones that are implemented in discrete time, for use in digital IIR filters.

His work, as important as it was in its own right, was a part of a continuum of progress in communications and electronics that since his time has brought forward color television, the personal computer, the Internet, cable and satellite radio and TV, personal mobile phones, audio, video and computing, digital stereo radio on both the medium wave and VHF-FM bands, and digital high definition television on VHF, UHF, cable and satellite.

It uses digital logic to count the number of cycles during a time interval established by a precision quartz time base.

Scanned documents are limited to the amount of time the user takes to load the document in a scanner and for the device to process a digital file.

Java was originally designed for interactive television, but it was too advanced for the digital cable television industry at the time.

Johnson has also signed up with " Operation Immortality ", a project to create a digital time capsule of their DNA and humanity's achievements in the event of a global calamity.

" The project brought together the world's top photographers, editors, programmers, and interactive designers to create a digital time capsule of online life.

He is most notable as one of the pioneers in the search for extraterrestrial intelligence, including the founding of SETI, mounting the first observational attempts at detecting extraterrestrial communications in 1960 in Project Ozma, developing the Drake equation, and as the creator of the Arecibo Message, a digital encoding of an astronomical and biological description of the Earth and its lifeforms for transmission into the cosmos.

* Entitlement Control Message, a message carrying conditional access information in a digital broadcast conditional access system

XML Signature is more flexible than other forms of digital signatures such as Pretty Good Privacy and Cryptographic Message Syntax, because it does not operate on binary data, but on the XML Infoset, allowing to work on subsets of the data, having various ways to bind the signature and signed information, and perform transformations.

From 2008, the BBC gradually began to drop the BBCi name from its digital interactive TV services also, replacing it with the name BBC Red Button.

From the 1990s to the present day, there has been a progressive movement from traditional film opticals to an integrated digital film environment, with special effects, cutting, colour grading, and other post-production tasks all sharing the same all-digital infrastructure.

From simple to advanced, these are: relying on the game's AI to control most actions, digital puppetry, recamming, and precise scripting of actions.

From this viewpoint, the A-law and μ-law algorithms ( G. 711 ) used in traditional PCM digital telephony can be seen as a very early precursor of speech encoding, requiring only 8 bits per sample but giving effectively 12 bits of resolution.

From the 1970s, the popularity of modern digital circuitry rapidly grew.
