Beginning of Digital Broadcasting
. 2000 Sydney Olympic Games 2000 Digital BS broadcasting begins On December 1, 2000, digital satellite broadcasting, called BS Digital broadcasting, started its services in Japan.. It marked the beginning of a 21st century broadcasting that is driven by the two engines of Hi-Vision (HDTV) and data broadcasting.. Digital HDTV has long been a dream of broadcasting engineers.. The introduction of digital technology to the world’s broadcasting media started with development of the PCM recorder in 1967 and other devices.. How digital technology can best be utilized in broadcasting has become one of the most significant research topics along with HDTV development.. “Integrated Services Digital Broadcasting (ISDB)” In 1982, STRL proposed a future digital broadcasting called “Integrated Services Digital Broadcasting (ISDB).” This was an entirely new idea concerning broadcasting services in which all the data including video/sound/textual data/still pictures wou ld be transmitted as digital signals on a single radio wave.
BROADCAST TECHNOLOGY
ISDB-T -Digital Terrestrial Television/Sound/Data Broadcasting in Japan- (Courtesy Asia-Pacific Broadcasting Union.) Kenichi Tsuchida, Naohiko Iai, Masayuki Takada, Syunji Nakahara, Shigeki Moriyama and Makoto Sasaki (Digital Broadcasting Networks) Integrated Services Digital Broadcasting (ISDB) is an emerging digital broadcasting concept.. The three kinds of systems, ISDB-S (Satellite), ISDB-T (Terrestrial) and ISDB-C (Cable) were developed in Japan to provide flexibility, expandability and commonality for the multimedia broadcasting services using each network.. Since digital satellite broadcasting began service using ISDB-S in December of last year in Japan, we would like to introduce the three ISDB systems mentioned above.. Abstract The Integrated Services Digital Broadcasting - Terrestrial (ISDB-T) system was developed to provide flexibility, expandability, and commonality for multimedia broadcasting services using terrestrial networks.. The results of the field trials showed the feasibility of ISDB-T system for digital terrestrial television/sound/data broadcasting services.
DVB - Digital Video Broadcasting
DVB - Digital Video Broadcasting Il servizio DVB-T è realizzato secondo le specifiche presentate nella norma ETSI ETS 300 744 che considera tecniche di compressione video e audio secondo lo standard MPEG.. In particolare il sistema di codifica audio si attiene allo standard MPEG LayerII (MUSICAM) già usato nel Digital Audio Broadcasting.. Anche per il DVB-T, come per il DAB, si può quindi parlare di bouquet di servizi potendo trasmettere da 2 fino a 4 programmi a definizione standard (SDTV) più servizi di data broadcasting.
DVB - Digital Video Broadcasting
DVB - Digital Video Broadcasting The DVB-T service will be carried out in line with the specifications presented in the ETSI ETS 300 744 rule which considers video and audio compression techniques according to the MPEG standard.. In particular, the audio coding system complies with the MPEG LayerII (MUSICAM) standard which has been already used in the Digital Audio Broadcasting.. As is the case with DAB, also in the case of DVB-T, we can speak of a range of services since we can broadcast 2-4 programs at standard definition plus data broadcasting services.. Obviously, the creation of a SFN network for the DVB-T poses the same stringent conditions on the signal broadcasting plants as those already incurred for the DAB: same signal content, synchronization in time and consistency in frequency.. Besides pay services, the DVB-T system is the most effective solution for the broadcasting of free-to-air TV services; create the only practical means for portable reception; to reduce the network implementation costs, thanks to the re-use of the existing analog infrastructure; carry out the regional/local broadcasting.

BS Digital Broadcasting 1-2
BS digital broadcasting is supported by many new technologies.. BS digital broadcasting can adopt a variety of modulation schemes suitable for information, such as video, audio, and data, to mitigate the service shut-off problem by rain.. Once ISDB services are transmitted via broadcasting satellite, subscribers of cable TV networks should be able to enjoy its services.. The AAC is applied for BS digital TV broadcasting.. In addition to standard 2-channel stereo and bilingual broadcasting, this system supports 5-channel surround-sound.. NHK has carried out formal listening tests of AAC and has confirmed that it satisfies the broadcasting quality at approximately half the bit rate of MPEG-2 BC (Backward Compatible), which is another MPEG Standard.. The ability to save data transmitted by digital broadcasting automatically and to access relevant information on programs.. We will continue to develop Home Servers that will provide high-performance, low-cost viewer services for the launch of digital broadcasting.

Digital Broadcast Industry Trends
| Broadcast End Market Video Production Markets Video Delivery Markets Broadcast Solutions Broadcast Resources > > > Industry Trends Digital Broadcast Industry Trends The conversion from analog to digital television broadcasting is already underway in many countries, creating new business opportunities for silicon providers and broadcast equipment manufacturers, as well as television broadcasters and broadband service providers.. The rapid growth of these opportunities is further driven by government timelines put forth in many countries to transition to digital terrestrial broadcasting and cease analog broadcasting altogether.. Governments can benefit by reallocating and auctioning the now available analog terrestrial spectrum, and create opportunities to promote literacy and information access programs through digital broadcasting.. Digital Television Standards Various standards organizations have been formed to influence digital television (DTV), including the Society of Motion Picture and Television Engineers (SMPTE), Advanced Television Systems Committee (ATSC), the Digital Video Broadcasting (DVB) project, and the Association of Radio Industries and Businesses (ARIB).

Broadcast Once, Watch Anywhere . Broadcast Once, Watch Anywhere JSR 272 Aims to Deliver Interactive TV on the Go by Frank Sommers May 18, 2005 Summary Digital broadcasting has recently emerged to bring live television to cell phones, PDAs, and other mobile devices.. Addressing those constraints, DVB-H (Digital Video Broadcasting - Handhelds) adapts the emerging DVB standard to mobile devices [3 ].. "Digital broadcasting is another trend for mobile devices that developers should be aware of." "It ususally takes between one and one-and-a-half years to produce a standard through the JCP.. In Japan, the Integrated Services Digital Broadcasting (ISDB-T) standard offers audio, video, and multimedia not only to HDTV-enabled TVs, but also to mobile devices.
Server: Broadcast Video Scenario
. When using Windows Media technologies, the source is a server running Windows Media Services.For broadcasting, an alternate Radio Frequency (RF) spectrum, other than what is used for a cell phone signal, is usually implemented.. The network you will use to deliver the broadcast must be capable of handling multicast.Several digital mobile broadcast technologies that are designed specifically for mobile broadcasting are available, such as Digital Video Broadcasting: Handheld (DVB-H), Digital Multimedia Broadcasting (DMB), Terrestrial Integrated Services Digital Broadcasting (ISDB-T), and Digital Audio Broadcasting (DAB).. For example, in most cases, the user cannot pause, fast-forward, or rewind the stream.The broadcasts may be delivered using digital mobile broadcast technologies that can provide more reliability and lower power demand, such as Digital Video Broadcasting: Handheld (DVB-H), Digital Multimedia Broadcasting (DMB), Terrestrial Integrated Services Digital Broadcasting (ISDB-T), and Digital Audio Broadcasting (DAB).
