Terrestrial television is a term which refers to modes of television broadcasting which do not involve satellite transmission or via underground cables. Terrestrial television broadcasting dates back to the very beginnings of television as a medium itself and there was virtually no other method of television delivery until the s with the beginnings of cable television, or community antenna television CATV.

The first non-terrestrial method of delivering television signals that in no way depended on a signal originating from a traditional terrestrial source began with the use of communications satellites during the s and s of the twentieth century.

The analogue television picture is "drawn" several times on the screen 25 in PAL system as a whole each time, as in a motion picture film, regardless of the content of the image. Satellite television is television signals delivered by means of communications satellites and received by satellite dishes and set-top boxes. In many areas of the world it provides a wide range of channels and services, often to areas that are not serviced by terrestrial or cable providers.

Satellite television, like other communications relayed by satellite, starts with a transmitting antenna located at an uplink facility which have very large uplink satellite dishes, as much as 9 to 12 meters 30 to 40 feet in diameter what results in more accurate aiming and increased signal strength at the satellite. The evolution of LNB was a need, so the designs for microstrip based converters were adapted for the C-Band taking advantage of its central design that was the concept of a block for down conversion of a range of frequencies to a lower, and technologically more easily handled block of frequencies, the IF - intermediate frequency.

The advantages of using an LNB are that cheaper cable could be used to connect the indoor receiver with the satellite TV dish and LNB, and that the technology for handling the signal at L-Band and UHF was far cheaper than that for handling the signal at C-Band frequencies. The shift to cheaper technology from the 50 Ohm impedance cable and N-Connectors of the early C-Band systems to the 75 Ohm technology and F-Connectors allowed the early satellite TV receivers to use what were in reality modified UHF TV tuners which selected the satellite television channel for down conversion to another lower intermediate frequency centered on 70 MHz where it was demodulated.

This shift allowed the satellite television industry to change to a far more commercial mass production one. The satellite receiver demodulates and converts the signals to the desired form outputs for television, audio, data, etc. Cable Television or Community Antenna Television CATV is a system for distribution of audiovisual content for television, FM radio and other services to consumers through fixed coaxial cables, avoiding the traditional system of radio broadcasting antennas broadcast television and have widespread use, mainly through the pay-TV services.

The use of different frequencies allows many channels to be distributed through the same cable, without separate wires for each, and the tuner of the TV or Radio selects the desired channel from among all transmitted. A cable television system begins at the head end, where the program is received and sometimes originated , amplified, and then transmitted over a coaxial cable network. The architecture of the network takes the form of a tree, with the "trunk" that carries the signals in the streets, the "branches" carrying the signals for buildings and, finally, the "arms" carrying the signals to individual homes.

The coaxial cable has a bandwidth capable of carrying a hundred television channels with six megahertz of bandwidth each, but the signals decay quickly with distance, hence the need to use amplifiers to "renew" the signals periodically to boost them. Backbone trunks in a local cable network frequently use optical fibre to minimize noise and eliminate the need for amplifiers as optical fibre has considerably more capacity than coaxial cable and allows more programs to be carried without signal lost or noise adding.

Most of the TV tuners are able to directly receive the cable channels, which are usually transmitted in the RF radio frequency band, however, many programs are encrypted and subject to a tariff itself and in such cases, you must install a converter between the cable and the receiver. DTTV is transmitted on radio frequencies through the airwaves that are similar to standard analogue television, with the primary difference being the use of multiplex transmitters to allow reception of multiple channels on a single frequency range such as a UHF or VHF channel.

The amount of data that can be transmitted and therefore the number of channels is directly affected by the modulation method of the channel. In general a 64QAM channel is capable of transmitting a greater bit rate, but is more susceptible to interference. This is called hierarchical modulation. DTTV is received via a digital set-top box, or integrated receiving device, that decodes the signal received via a standard aerial antenna, however, due to frequency planning issues, an aerial with a different group usually a wideband may be required if the DTTV multiplexes lie outside the bandwidth of the originally installed aerial.

The HDTV is transmitted digitally and therefore its implementation generally coincides with the introduction of digital television DTV , technology that was launched during the s. High-definition television HDTV yields a better-quality image than standard television does, because it has a greater number of line resolution. The visual information is some 2 to 5 times sharper because the gaps between the scan lines are narrower or invisible to the naked eye.

The larger the size of the television the HD picture is viewed on, the greater the improvement in picture quality. On smaller televisions there may be no noticeable improvement in picture quality. The lower-case "i" appended to the numbers denotes interlaced; the lower-case "p" denotes progressive: With the interlaced scanning method, the 1, lines of resolution are divided into pairs, the first alternate lines are painted on a frame and then the second lines are painted on a second frame; the progressive scanning method simultaneously displays all 1, lines on every frame, requiring a greater bandwidth.

Pay-per-view often abbreviated PPV offers a system by which a television audience can purchase events to view on TV-monitors via private telecast of that event to their homes.

The broadcaster shows the event at the same time to everyone ordering it as opposed to video-on-demand systems, which allow viewers to see the event at any time and can be purchased using an on-screen guide, an automated telephone system, or through a live customer service representative. Events often include feature films, sporting events, adult content movies and "special" events.

VoD systems either stream content through a set-top-box, allowing viewing in real time, or download it to a device such as a computer, digital video recorder, personal video recorder or portable media player for viewing at any time. For disk-based streaming systems which store and stream programs from hard disk drive, trick modes require additional processing and storage on the part of the server, because separate files for fast forward and rewind must be stored. Memory-based VoD streaming systems have the advantage of being able to perform trick modes directly from RAM, which requires no additional storage or CPU cycles on the part of the processor.

It is possible to put video servers on LANs, in which case they can provide very rapid response to users. Streaming video servers can also serve a wider community via a WAN, in which case the responsiveness may be reduced.

It can be known "normal" TV channels or channels specifically designed for the Internet. Web TV, in a simplified form, is nothing more than the provision of video and audio over the Internet; and the way to assist the transmission varies from the monitor of a computer through the use of an iPod or a mobile phone to the TV set if one have the decoder. Moreover, thanks to IP Internet Protocol , will be possible the combination of several interfaces in a multi-service unit and the broadcast and distribution of diverse and varied services on the same network, which previously required differentiated infrastructure, including: TV signals, telephone service and broadband Internet access, setting a platform we know today as Triple Play.

In essence, the triple play concept is not entirely new because, in terms of services, there are some years ago that are available some solutions combining a mix of TV services, telephony and Internet access. Studies show that the churn rate voluntary abandonment of service of the offer triple play subscribers is substantially lower than that observed when the voice, data and TV are sold on a non-convergent way.

Another factor is the progress in access technologies and platforms for packet telephony and video. The access over optical fibre in its more popular form, known as PON passive optical network , reflects an even more daring way, resulted in significant investments in that technology, seeking for high-speed Internet access, voice and multi-channel of high-definition TV union.

Progress in video distribution systems is on the way too. The main driver is integrated platforms consisting of set-top-boxes, servers and video content protection system DRM - digital rights management , together with appropriate tools, middleware and billing, allow the provision of a variety of TV services in several formats, such as streaming, video on demand and time-shifted TV, based on a combination of underlying IP networks and DSL or optical access systems.

In this context, the sophistication of algorithms for compression of video signals has a relevant role. The search for a strategy to offer multiple play-based dual, triple, quadruple etc. CABLE TV Cable Television or Community Antenna Television CATV is a system for distribution of audiovisual content for television, FM radio and other services to consumers through fixed coaxial cables, avoiding the traditional system of radio broadcasting antennas broadcast television and have widespread use, mainly through the pay-TV services.

Цвета покидали небо; теплые красные и золотые тона вытекли прочь, оставив антарктически-синий, постепенно сгустившийся в ночь. Задержав дыхание, Элвин ждал момента, ведомого из всего человечества лишь ему - момента, когда оживет и затрепещет первая звезда. С тех пор как он последний раз побывал в этом месте, прошло много недель, и он знал, что картина ночного небосвода должна была измениться.

Но он не был готов впервые увидеть Семь Они не могли называться иначе: непрошенная фраза сама сорвалась с его губ.

За годы, лежащие впереди, предстояло сделать так. Джизирак знал, что стоит на рубеже двух эпох: он уже повсюду чувствовал убыстряющийся пульс человечества.

Это циклопическое и такое пустынное помещение исчезло почти так же стремительно, как и возникло. Образ его вызвал в сознании Олвина что-то похожее на благоговение. Впервые он осознал значение той огромной затерянной карты под Диаспаром. Мир оказался куда более полон чудесами, чем ему когда-либо представлялось. Олвин снова глянул на табло. Ничто не изменилось: ему понадобилось меньше минуты, чтобы промелькнуть через пустынную станцию.

Машина снова набирала скорость, и, хотя движение по-прежнему почти не ощущалось, стены туннеля уже отбрасывались назад с быстротой, о порядке которой он не мог и догадываться. Казалось, целая вечность прошла, прежде чем снова наступило почти неощутимое изменение в характере вибрации. Теперь на табло значилось: Лиз. Минута эта оказалась самой долгой в жизни Олвина.

И все же за этот ничтожный срок она изменилась неузнаваемо: куда как больше, нежели имела право по логике естественного хода событий. Великие солнца, что когда-то, во времена своей гордой юности, пылали столь неистово, теперь угасали, приговоренные. Но Олвин никогда не видел неба в его древней красе и поэтому просто не представлял себе, что же оказалось утрачено.

Холод, пронизывающий его до костей, заставлял возвращаться обратно, в город.

Насколько хватал глаз, вокруг не было ничего, кроме леса и ровных пространств, заросших Олвин перевел взгляд на горизонт, и там, над кромкой деревьев, простираясь справа налево исполинской дугой, замыкающей в себе мир, темнела каменная гряда, по сравнению с которой даже самые гигантские сооружения Диаспара показались бы карликами. Гряда эта лежала так далеко, что детали ее скрадывались расстоянием, но все-таки угадывалось в ее очертаниях что-то такое, что до глубины души поразило Олвина.

Я в одном только уверен. Когда Лиз существовал, он был очень похож на Диаспар. Все города в основе своей были похожи. И неудивительно, что в конце концов они были покинуты людьми, которые стянулись в один центр -- в Диаспар.

На кой, спрашивается, ляд было им иметь их больше одного?. Олвин едва слышал Шута. Он был поглощен разглядыванием этого диковинного снаряда, нетерпеливо пытаясь найти вход.

Если машина управлялась централизованно или при помощи устного кодового приказа, ему бы ни за что не удалось заставить ее повиноваться ему и она до конца его жизни так и осталась бы сводящей с ума загадкой.

Шорох ветра в листве он слышал и раньше, но здесь его сопровождали тысячи других неясных шумов, ничего не говоривших уму. Его атаковали неизвестные ароматы, исчезнувшие даже из памяти его рода.

Тепло, изобилие расцветок и благоуханий, невидимое присутствие миллионов живых существ обрушились на него с почти сокрушительной силой. Вдруг он наткнулся на озеро. Деревья с правой стороны внезапно расступились, и перед ним оказался водный простор с точками крошечных островков. Никогда в своей жизни Элвин не видел такого количества воды: самые большие пруды в Диаспаре были в сравнении с этим почти лужами.

Стоит только каждому из них сформировать мысль-пожелание, как он сразу очутиться -- во всех смыслах, кроме физического,-- перед лицом любого избранного им в собеседники жителя Диаспара. Эти люди не ведали, что такое скука, поскольку имели доступ ко всему, что происходило в мире воображения и в реальной жизни с тех самых времен, когда был построен этот город.

Людей, чье сознание было устроено таким вот образом, город обеспечивал всем необходимым с безукоризненной полнотой. А того, что такое существование является, в сущности, совершенно бесплодным, не понимал даже и сам Олвин.

По мере того как молодые люди выбирались из центра города к его окраине, число встречных на улицах все уменьшалось, и, когда тротуар плавно остановился у очень длинной платформы, сложенной из яркого мрамора, вокруг них уже не было ни одной живой души. Они пересекли застывший водоворот вещества, из которого эта странная субстанция струящегося тротуара возвращалась к истоку, и остановились перед стеной, пронизанной ослепительно освещенными туннелями.

Олвин без колебаний выбрал один из них и ступил в .

Мне уже все равно. Когда я возвратился в усыпальницу Ярлана Зея, то обнаружил, что Алистра, оказывается, следила за нами. Надо думать, она сообщила Совету, что ты покинул Диаспар и что я тебе в этом помог.

Шли минуты. Это настроение медленно истаивало.

За ними не было ничего -- совсем ничего, разве что тягостная пустота песков, в которой человек -- поговаривали -- быстро сходил с ума. Тогда почему же эта пустота влекла его так, как ни одного из окружающих его людей.

Олвин никак не мог этого понять.

Они только потратили бы зря время в бесплодных разговорах, а затем поступили бы точно так же, как сейчас Алистра. Джезерак выслушал ее рассказ без видимых эмоций.
