Widespread use of open standards ( such as MPEG-2, DAB, DVB, etc.

While it is not technically part of the ATSC or DVB broadcast standards as of yet, reports suggest that higher progressive frame rates will feature in the next-generation high-definition television broadcast standards.

The newer DVB standards DVB-S2 and DVB-T2 has the capacity to carry several HDTV channels in one multiplex.

Even the original DVB standards can carry more HDTV channels in a multiplex if the most advanced MPEG-4 compressions hardware is used.

Digital Video Broadcasting ( DVB ) and Digital Audio Visual Council ( DAVIC ) are European-formed organizations that developed some cable modem standards.

In particular, the IETF WGs on IP over Cable Data Network ( IPCDN ) and IP over Digital Video Broadcasting ( DVB ) produced some standards applicable to cable modem systems, primarily in the areas of Simple Network Management Protocol ( SNMP ) Management Information Bases ( MIBs ) for cable modems and other networking equipment that operates over CATV networks.

CCETT / France Télécom R & D contributed to various international standards, such as ISO / IEC MPEG and JPEG standards or DAB and DVB standards.

Digital Video Broadcasting ( DVB ) is a suite of internationally accepted open standards for digital television.

DVB standards are maintained by the DVB Project, an international industry consortium with more than 270 members, and they are published by a Joint Technical Committee ( JTC ) of European Telecommunications Standards Institute ( ETSI ), European Committee for Electrotechnical Standardization ( CENELEC ) and European Broadcasting Union ( EBU ).

Companies that manufacture a product which is compliant to one or more DVB standards have the option of registering a Declaration of Conformity for that product.

Part of the DAB digital radio and DVB digital television standards.

* Likewise, use of digital broadcasting standards such as the DVB and ATSC eliminates the issues introduced by modulation and demodulation of analogue signals.

At present there is no equivalent signal defined in the European DVB standards.

DMB-T / H is China's own standard ( including Hong Kong, though Hong Kong's cable operators use DVB ); the rest of the world remains mostly undecided, many evaluating multiple standards.

* DVB is an international standard for digital video broadcasting used by virtually all European broadcasters ; some North American providers use incompatible proprietary standards such as DSS ( DirecTV ) or DigiCipher ( Motorola ) which predate the DVB standardisation effort.

The ISAN identifier is incorporated in many draft and final standards such as AACS, DCI, MPEG, DVB, and ATSC.

When broadcast at 60 frames per second, 720p features the highest temporal ( motion ) resolution possible under the ATSC and DVB standards.

The ATSC, DVB and ISDB standards allow for broadband datacasting via DTV, though they do not necessarily define how.

Video providers in Europe must conform to the DVB standard which is a more comprehensive open standard governed by independent standards bodies.

Many television stations are now in the process of converting from analogue ( NTSC, PAL or SECAM ) broadcast, to digital TV ( ATSC broadcast, DVB or ISDB ).

They are prominently used in consumer electronics such as CDs, DVDs, Blu-ray Discs, in data transmission technologies such as DSL and WiMAX, in broadcast systems such as DVB and ATSC, and in computer applications such as RAID 6 systems.

For example, RS codes are used in the digital video broadcasting ( DVB ) standard DVB-S, but LDPC codes are used in its successor DVB-S2.

Many aspects of DVB are patented, including elements of the MPEG video coding and audio coding.

With the exception of SKY PerfecTV !, Japan uses different formats in all areas ( ISDB ), which are however quite similar to their DVB counterparts.

There are two different types, both employing the Digital Video Broadcasting ( DVB ) standard as their basis:

On digital platforms such as DVB, DAB, satellite and the Internet, the pips — although generated accurately — are not heard by the listener exactly on the hour.

technologies are available allowing the performance of the second generation DVB cable

The units are DVB-S compatible, and usually carry the DVB logo on the front.

In the DVB Project's Content Protection and Copy Management ( CPCM ) scheme, an Authorized Domain is a set of CPCM-compliant devices that " are owned, rented or otherwise controlled by members of a single household ", according to the DVB Project.

For all this, the takeup of PALplus has been marginal, and the future of this standard does not look very bright, since broadcasters are switching to digital television broadcasting ( DVB ).

The most common North American sources for free-to-air DVB satellite television are:

OpenCable devices are available to access encrypted content on U. S. cable systems, but as this is a full DRM system, and not just CA like DVB CI, every piece of hardware and software on the playback chain must be tested and licensed by CableLabs.

Examples of use are in roaming between overlapping wireless systems, e. g., IP over DVB, WLAN, WiMAX and BWA.

Unlike most DVB captions, CEA-708 captions are textual like traditional Line 21 captions.

These are defined within the terrestrial broadcast stream using the NorDig descriptor format within the DVB " Network Information Table.

The Linux kernel and the LinuxTV CVS include a fair number of drivers for commonly available PCI cards and USB devices, but the DVB subsystem core is also targeted towards Linux based set-top boxes.

* Packet ID, used to identify audio / video streams in DVB " Digital Video Broadcasting "

An additive scrambler ( descrambler ) used in Digital Video Broadcasting | DVB

The form factor is also used by the Common Interface form of Conditional Access Modules for DVB broadcasts, and by Panasonic for their professional " P2 " video acquisition memory cards.

Finally, it has been discovered recently that a common DVB USB stick ( with Realtek RTL2832U chip ) can be used as a wide-band SDR receiver.

In Europe, as well as in Australia, South Africa and India, DVB is used throughout.

Wherever the DVB trademark is used in relation to a product – be it a broadcast, a service, an application or equipment – the product must be registered with the DVB Project Office.

* MPEG-2 transport framing ( used in DVB )

The hierarchical modulation used on DVB is a unique case, which reduces the range of the full-definition signal, in exchange for an increase in the usable range of the lower-definition part of the video.

* Service ID, used in Digital Video Broadcasting ( DVB )

The Common Scrambling Algorithm ( or CSA ) is the encryption algorithm used in the DVB digital television broadcasting for encrypting video streams.

Were CSA to be broken, encrypted DVB transmissions would be decipherable, regardless of any proprietary conditional access ( CA ) system used.

This could seriously compromise paid digital television services, as DVB has been standardised on for digital terrestrial television in Europe and elsewhere, and is used by many satellite television providers.

Internet sites may be located offshore in countries where local laws permit the information and software to be distributed openly ; some of the more notorious software distributed to pirates ranges from NagraEdit ( a program intended to edit the information stored on Swiss-designed Kudelski NagraVision 1 smartcards ) to firmware which may be used to reprogram some free-to-air set-top boxes or desktop PCs equipped with Digital Video Broadcasting ( DVB ) tuner cards to permit them to decode encrypted broadcasts.

PC Card form factor is used as the Common Interface form of Conditional Access Modules for DVB broadcasts.

It is currently being used for Dish Network HDTV television signals, transmitted using DVB, on the K < sub > u </ sub > band transponders.
