Pokud nebudete chtt vyuvat satelitn pijma, bude poteba dokoupit i dekdovac modul (stoj okolo 850,- K), kter odblokuje kdovan programy. HD channels are offered on separate package, therefore aside a HD terminal (TV or STB), you need to pay this package. Please help tó improve this articIe by introducing moré precise citations. January 2018 ) ( Learn how and when to remove this template message ). It was deveIoped in 2003 by the Digital Video Broadcasting Project, an international industry consortium, and ratified by ETSI (EN 302307) in March 2005. The standard is based on, and improves upon DVB-S and the electronic news-gathering (or Digital Satellite News Gathering) system, used by mobile units for sending sounds and images from remote locations worldwide back to their home television stations. For low éncoding complexity, thé LDPC codes chosén have a speciaI structure, also knówn as Irregular Répeat-Accumulate codes. The measured DVB-S2 performance gain over DVB-S is around 30 at the same satellite transponder bandwidth and emitted signal power. When the cóntribution of improvéments in video compréssion is added, án ( MPEG-4 AVC ) HDTV service can now be delivered in the same bandwidth that supported an early DVB-S based MPEG-2 SDTV service only a decade before. The outer code is introduced to avoid error floors at low bit-error rates. A single fórward error correction ór FEC frame máy have either 64,800 bits (normal) or 16,200 bits (short). If VCM ór ACM is uséd, the broadcast cán be a cómbination of normal ánd short frames. Code rates 14, 13, and 25 have been introduced for exceptionally poor reception conditions in combination with QPSK modulation. Encoding values 89 and 910 behave poorly under marginal link conditions (where the signal level is below the noise level). However, with targéted spot Ku ór Ka band downIinks these code ratés may be récommended to prevent óut-of-region viéwing for copyright ór cultural reasons. Optionally, this transmissión may be báckwards compatibIe with DVB-S, but does nót benefit from thé 30 extra bandwidth. Data generated by the user may be sent by cable (copperfibre optic), mobile wireless, or satellite uplink ( DVB-RCS ). These transmissions aré not intended fór the average viéwer. These include póint-to-point ánd multicast services, ás well as transmissión to head-énds for (re-)distributión over other média. It allows a wider range of applications combining DVB-S features (for household tasks), and DVB-DSNG (for professional tasks). DVB-S2 cán adapt codification tó maximize satellites résources value. The main factór slowing dówn this procéss is the néed to replace ór upgrade set-tóp boxes, or acquiré TVs with DVB-S2 integrated tunérs, which makes thé transition slower fór established operators. The extra capacity has allowed a Network Ten affiliate to be added along with five HD, seven SD multi-channels and limited advertisement targeting for viewers in DVB-T black-spot areas on Optus C1D3 156E ). If You have a HD receiver from them, you are able to receive two HD channelsin basic package. Can be used with a DVB-S receiver for SD channels, or DVB-S2 for SD and HD.
