Key highlights in the development of digital cinema would likely include: demonstrations by TI of their DMD technology, real-time playback of compressed hi-resolution files by various vendors, and early HD presentations from D5 tape to digital projectors.

Some modern hi-fi equipment can be digitally connected using fibre optic TOSLINK cables, universal serial bus ( USB ) ports ( including one to play digital audio files ), or Wi-Fi support.

An important caveat about lossy compression is that ( formally, transcoding ) or editing lossily compressed files causes digital generation loss from the re-encoding.

End-users can use software that communicates with MusicBrainz to add metadata tags to their digital media files, such as MP3, Ogg Vorbis or AAC.

PGP encryption applications include e-mail and attachments, digital signatures, laptop full disk encryption, file and folder security, protection for IM sessions, batch file transfer encryption, and protection for files and folders stored on network servers and, more recently, encrypted and / or signed HTTP request / responses by means of a client side ( Enigform ) and a server side ( mod openpgp ) module.

Depending on application, the products feature desktop e-mail, digital signatures, IM security, whole disk encryption, file and folder security, self decrypting archives, and secure shredding of deleted files.

Although digital setting circles can be used to display a telescope's RA and Dec coordinates, they are not simply a digital read-out of what can be seen on the telescope's analog setting circles.

Compared to digital signals, analog signals are of higher density.

Although such a conversion can be prone to loss, most modern audio systems use this approach as the techniques of digital signal processing are much more powerful and efficient than analog domain signal processing.

Examples of software noise reduction are digital filtering, ensemble average, boxcar average, and correlation methods.

Slide rules and nomographs are the simplest, while naval gunfire control computers and large hybrid digital / analog computers were among the most complicated.

Authors may post the documents on their own websites, but they are required to link back to the digital library's reference page for the paper.

There are many types of electronic amplifiers, commonly used in radio and television transmitters and receivers, high-fidelity (" hi-fi ") stereo equipment, microcomputers and other electronic digital equipment, and guitar and other instrument amplifiers.

Minsk has a digital metropolitan network ; waiting lists for telephones are long ; fixed line penetration is improving although rural areas continue to be undeserved ; intercity-Belarus has developed fibre-optic backbone system presently serving at least 13 major cities ( 1998 ); Belarus's fibre optics form synchronous digital hierarchy rings through other countries ' systems ; an inadequate analogue system remains operational.

* Domestic: a fairly modern digital cable trunk line now connects switching centers in most of the regions ; the others are connected by digital microwave radio relay

To this day, it and BBC Parliament remain the only BBC " digital " channels which are made available to analogue cable subscribers.

The bilinear transform is a special case of a conformal mapping ( namely, the Möbius transformation ), often used to convert a transfer function of a linear, time-invariant ( LTI ) filter in the continuous-time domain ( often called an analog filter ) to a transfer function of a linear, shift-invariant filter in the discrete-time domain ( often called a digital filter although there are analog filters constructed with switched capacitors that are discrete-time filters ).

Local printers are also increasingly taking over the process of photofinishing as digital photo printers become commonplace.

In practice, digital computation is often used to simulate natural processes ( for example, evolutionary computation ), including those that are more naturally described by analog models of computation ( for example, artificial neural network ).

Compact Discs are increasingly being replaced or supplemented by other forms of digital distribution and storage, such as downloading and flash drives, with audio CD sales dropping nearly 50 % from their peak in 2000.

Recordable CDs are an alternative to tape for recording music and copying music albums without defects introduced in compression used in other digital recording methods.

A video camera's analog-to-digital converter ( ADC ) converts its analog signals into digital signals, which are then passed through a video compressor for digital transmission or storage.

For pre-recorded presentations, the rendered frames are transferred to a different format or medium such as film or digital video.

In digital-video and still-image color spaces such as Y ' CbCr, the luma and chrominance components are digital sample values.

The digital data collected by the telescope is then transmitted and displayed to the user by means of the Internet.

Since then, with several relaunches, an increase in funding and resources from the BBC and improvements in digital television technology, the channel has been able to diversify content, with two minute looped bulletins available to view via BBC Red Button, BBC News Online and the BBC's mobile website, alongside individual weather and sport bulletins.

Since then, carriage on digital cable, satellite and digital terrestrial has introduced Channel 4 to Welsh homes where it is now universally available.

The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file.

Codecs do the opposite ( convert audio analog to digital and then computer digital sound back to audio ).

A receiving device then converts the digital signals back to analog using an audio decompressor, for playback.

For example, when an ordinary RGB digital image is compressed via the JPEG standard, the RGB colorspace is first converted ( by a rotation matrix ) to a YCbCr colorspace, because the three components in that space have less correlation redundancy and because the chrominance components can then be subsampled by a factor of 2 or 4 to further compress the image.

This service involves installing a special telephone interface at the customer's premises that converts the analog signals from the customer's in-home wiring into a digital signal, which is then sent on the local loop ( replacing the analog last mile, or Plain old telephone service ( POTS )) to the company's switching center, where it is connected to the Public switched telephone network ( PSTN ).

The first step is usually to convert the signal from an analog to a digital form, by sampling and then digitizing it using an analog-to-digital converter ( ADC ), which turns the analog signal into a stream of numbers.

Digital video was first introduced commercially in 1986 with the Sony D-1 format, which recorded an uncompressed standard definition component video signal in digital form instead of the high-band analog forms that had been commonplace until then.

While low-quality at first, consumer digital video increased rapidly in quality, first with the introduction of playback standards such as MPEG-1 and MPEG-2 ( adopted for use in television transmission and DVD media ), and then the introduction of the DV tape format allowing recording direct to digital data and simplifying the editing process, allowing non-linear editing systems ( NLE ) to be deployed cheaply and widely on desktop computers with no external playback / recording equipment needed.

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 ).

The gel can then be photographed usually with a digital or polaroid camera.

Mechanical tools to help humans with digital calculations were then called " calculating machines ", by proprietary names, or even as they are now, calculators.

Machines with a digital display calculate the user's power by measuring the speed of the flywheel during the stroke and then recording the rate at which it decelerates during the recovery.

Hoffmann-La Roche then licensed the invention to the Swiss manufacturer Brown, Boveri & Cie who produced displays for wristwatches during the 1970s and also to Japanese electronics industry, which soon produced the first digital quartz wrist watches with TN-LCDs and numerous other products.

Without this capacity, which is often the case in practice, to produce a representation with lower resolution or lower fidelity than a given one, one needs to start with the original source signal and encode, or start with a compressed representation and then decompress and re-encode it ( transcoding ), though the latter tends to cause digital generation loss.

In addition to, or instead of, directly viewing the object through the eyepieces, a type of sensor similar to those used in a digital camera is used to obtain an image, which is then displayed on a computer monitor.

Macrovision then divested other areas of its non digital entertainment business, including TryMedia, eMeta, TV Guide Magazine, TV Guide Network and TVG-Horse Racing.
