Other modules in the system may include components like cartridges, tonearms, hi-fi turntables, Digital Media Players, digital audio players, DVD players that play a wide variety of discs including CDs, CD recorders, MiniDisc recorders, hi-fi videocassette recorders ( VCRs ) and reel-to-reel tape recorders.

MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related standards, adding new features such as ( extended ) VRML support for 3D rendering, object-oriented composite files ( including audio, video and VRML objects ), support for externally specified Digital Rights Management and various types of interactivity.

In digital radio, both the Eureka 147 system of digital audio broadcasting and the in-band on-channel HD Radio, FMeXtra, and Digital Radio Mondiale systems can multiplex channels.

Red Book is the standard for audio CDs ( Compact Disc Digital Audio system, CDDA or CD-DA ).

Sony's MiniDisc was one of two rival digital systems, introduced in 1992, that were both targeted as a replacement for the Philips analog cassette audio tape system: the other was Digital Compact Cassette ( DCC ), created by Philips and Matsushita.

Sony had originally intended for Digital Audio Tape ( DAT ) to be the dominant home digital audio recording format, replacing the analog cassette.

Unlike the Digital Compact Cassette, or the analog compact audio cassette, the disc is a random-access medium, making seek time very fast.

Digital audio refers to technology that records, stores, and reproduces sound by encoding an audio signal in digital form instead of analog form.

The service can be accessed via Digital terrestrial television ( DTT ) ( DVB-T ), satellite television ( DVB-S ) and cable television ( DVB-C ).

Computer files can be also stored on other media in some cases, such as magnetic tapes, compact discs, Digital Versatile Discs, Zip drives, USB flash drives, etc.

Digital TV is more tolerant of interference than analog TV, and this is the reason a smaller range of channels can carry an all-digital set of television stations.

Digital techniques, such as ray-tracing ( graphics ) | ray tracing, can also render 3D models with shallow depth of field for the same effect.

* A multiple Sequencer which can mix MIDI tracks with Digital Audio ;

Digital video can be copied with no degradation in quality.

Cameras such as the Arri Alexa can capture 2K resolution images, the Red Digital Cinema Camera Company's Red One and Red Scarlet can record 4K, the Red Epic 5K, and Sony's F65 CineAlta camera can record 4K down-sampled from 8K.

Digital effects designed for DJs are often sold in tabletop models, so that the units can be placed alongside a mixer, turntables and CD scratching gear.

Digital data can be sent by shifting the carrier's frequency among a range of settings, a technique known as frequency-shift keying ( FSK ).

Jim Davis has also collaborated with Ball State University and Pearson Digital Learning to create Professor Garfield, a site with educational games focusing on math and reading skills and with Children's Technology Group to create MindWalker, a web browser that allows parents to limit the websites their children can view to a pre-set list.

They also typically do not have other requirements that are common in copyleft licences, like restrictions on formats that the work can be available in or whether Digital Rights Management may be used on the product.

One of the main features of the industry, Weta Digital can be credited with the popularity of Media Studies in NZ.

Digital pathology is enabled in part by virtual microscopy, which is the practice of converting glass slides into digital slides that can be viewed, managed, and analyzed.

Digital modulation methods can be considered as digital-to-analog conversion, and the corresponding demodulation or detection as analog-to-digital conversion.

Although designed for memory, Secure Digital Input / Output ( SDIO ) and CompactFlash cards are available that provide accessories like Wi-Fi or digital cameras, if the device can support them.

In some related signature schemes, the private key is used to Digital signature | sign a message ; anyone can check the signature using the public key.

* Digital signatures: a message signed with a sender's private key can be verified by anyone who has access to the sender's public key, thereby proving that the sender had access to the private key and, therefore, is likely to be the person associated with the public key used.

Digital signature schemes can be used for sender authentication and non-repudiation.

Digital signature schemes have the property that signatures can be computed only with the knowledge of the correct private key.

Digital television channels are the same for legacy reasons, however through multiplexing, each physical radio frequency ( RF ) channel can carry several digital subchannels.
