  • 6. After 13 years of development, we formed an enterprise culture of honesty andinnovation. We constantly pursue excellence, emphasize commitment andpractice. We are willing to make contribution to the development of digital TVindustry together with our colleagues.Chapter 1 Requirement Analysis1. Requirement AnalysisThe digital cable television or community antenna television (CATV) systemcould provide the best quality TV programs to the spectators because the signalsare transmitted by hybrid fiber coax (HFC) network. The total system includeshead-end system, HFC network, and clients of STB and TV set. Chart 1-1 CATV network structureThere are plenty of bandwitch in HFC network, so the number of programsmaybe more than 100. The programs could come from satellite, fibre, local TVstation.COMPUNICATE TECHNOLOGIES INC. 6ADD:No. 901-905, Block B ( Office Section) Maples International Center, No. 32 XizhimenNorth Street, Haidian District, Beijing 100082 P.R.C.Tel:+86 10 62272800 Fax:+86 10 62277908Website:www.compunicate.cn
  • 7. Moreover, the project should comply with international standards, such as DVBand TCP/IP. The proposal should be advanced, practical, security, and openend,which could be updated and expanded in future.2. Head-end System ConstitutionBasic Head-End PlatformThe basic head-end system should receive all kinds of TV signal, and convert tostandard transport stream (TS), then broadcasting to the HFC network or IPnetwork. The mainly equipments include satellite dish, receiver, multiplexer,modulator, CAS and EPG system, etc.Conditional Access SystemBased on the head-end hardwares, CTI-CAS, which includes CAS Core moduleand SMS module, could support TV operators pay-TV service. The CAS Coremodule works with scrambler to scrambling the transport streams, as well asworks with SMS module for managing subscribers, statistic, authority, andaccount in order to guaranetee the business income and improve themanagement.Value-Added ServiceIn the future, operators could add some value-added services, such as mosaicnavigation, video broadcasting, short message charge, etc.3. HFC networkThe Hybrid Fiber-Coaxial (HFC) network is composed of optical fiber main line,coaxial cable branch, and access network. The fiber optic network extends fromthe cable operators master headend, sometimes to regional headends, and outCOMPUNICATE TECHNOLOGIES INC. 7ADD:No. 901-905, Block B ( Office Section) Maples International Center, No. 32 XizhimenNorth Street, Haidian District, Beijing 100082 P.R.C.Tel:+86 10 62272800 Fax:+86 10 62277908Website:www.compunicate.cn
  • 8. to a neighbourhoods hubsite, and finally to a fiber optic node which servesanywhere from 25 to 2000 homes.4. Receiver SystemThe most popular receiver is Set Top Box. Recently the digital TV set sale isincreasing. The receivers should have the functions of demodulating, decodingMPEG-2 signal, EPG display. Some advanced receivers could show data-broadcasting content and support mosaic guide. If there are scrambled programs,the corresponding descrambling funciton is needed.COMPUNICATE TECHNOLOGIES INC. 8ADD:No. 901-905, Block B ( Office Section) Maples International Center, No. 32 XizhimenNorth Street, Haidian District, Beijing 100082 P.R.C.Tel:+86 10 62272800 Fax:+86 10 62277908Website:www.compunicate.cn
  • 9. Chapter 2 Total solution of head-end systemThe cable network could have plenty of programs, which come from satellite,SDH, or local TV, etc. The quatity of equipments is mainly due to the programsources. For example, if several programs are from the same satellite, and havethe same frequency parameters, they could be received by one satellite receiver.However, if they are from different satellite, we have to use more satellitereceivers. The situation of SDH adapter is similar to satellite receiver.Because the electromagnetic environment in HFC is very good, the modulator isalmost quadrature amplitude modulation (QAM). The mode of 64 QAM isrecommended by which the digital bitrate could achieve 38 Mbps in an 8 MHzchannel. If each program bitrate is 6 Mbps, 6 programs could be multiplexed inone channel. If each program bitrate is 4.5 Mbps, 8 programs could be together.The excess bandwidth about 2 Mbps is commonly used for CAS and EPGpackets.Fomula is D * N * 188/204 = D * (lg QAM/ lg2) * 188/204D is symbolrate, could be estimated like this: Bandwidth / (1+0.16), or thecommon value in some countries. N is the logarithm of the QAM mode. In RScode, a 204 bytes packet is used to transmit 188 bytes net data.Here are some reference parameters below. Bandwidth Symbolrate 32QAM 64QAM 256QAM 7.975 MHz 6.875 Msps 31.679 Mbps 38.015 Mbps 50.686 Mbps 6 MHz 5.057 Msps 23.302 Mbps 27.962 Mbps 37.283 Mbps Table 2-1 Bitrate in different environmentsCOMPUNICATE TECHNOLOGIES INC. 9ADD:No. 901-905, Block B ( Office Section) Maples International Center, No. 32 XizhimenNorth Street, Haidian District, Beijing 100082 P.R.C.Tel:+86 10 62272800 Fax:+86 10 62277908Website:www.compunicate.cn

  • 13. Comment: Some TV programs could be received by same receiver Table 2-2 Product list3. System DescriptionThe recommended head-end solution includes mainly Compunicate products,and some our purchased products in long term, which benefit quick supply andeasy intergration. In the stage of construction, operators could consult thissystem for bidding sub-systems respectively in order to use the best product. Weare glad to support in technique and engineering as always.4.1 Satellite programThere are two kinds of satellite programs which have to be received myPowervu9850 or free-to-air (FTA) SD & HD program. The free program could bereceived by MPEG-2 SD or MPEG-4 SD satellite receiver.In cable network, the satellite programs could be transmitted without encoding.So the receiver should output TS stream directly which maybe including severalprograms (MPTS). If several programs have the same frequency, symbolrate,polarization, and they are from the same satellite, they could be transmitted bythe same receiver.4.2 Signal Process (multiplex, scramble, modulate)All the output signals of receivers, enter into the multiplexers and scramblers.Here we suggest use EM800 Platform (including ASI input cards) which cansupport ASI and IP output and S100 Scrambler for DVB-C STB and IP STB..Compunicate EM800 Platform supports 4PCS ASI input cards in 1U chassis atmost and each ASI input card can support 4 ASI input (SPTS or MPTS), supportsASI and IP outputs.COMPUNICATE TECHNOLOGIES INC. 13ADD:No. 901-905, Block B ( Office Section) Maples International Center, No. 32 XizhimenNorth Street, Haidian District, Beijing 100082 P.R.C.Tel:+86 10 62272800 Fax:+86 10 62277908Website:www.compunicate.cn
  • 14. The EM800 platform could multiplex all input transport streams into one multiprogram transport stream (MPTS). The scrambler could scramble the clear TSstream into scrambling TS stream by interchanging message with CAS system.The newwork management system could monitor all ASI port by GUI interface,support editing NIT/PAT/PMT/SDT/CAT tables and transferring all tables.The scrambled streams enter modulator and transmitter for broadcasting overcarrier waves.4.4 Electronic Program GuideCompunicate SI-EPG system could insert service informations (SI) into transportstreams, including detailed event information table (EIT) which could be used forelectronic program guide (EPG) service.SI-EPG system has Client / Server structure, based on network and distributeddatabase system. The software module could be distributed on severalworkstations and servers or installed in one server. In this case, it is enough touse one edit workstation, one SI server and one SI injector.Actually, the SI-EPG system could not only send EPG information, but also sendall SI information. These informations have different feature in application. The SIinformation is needed to be edited only when the DTV head-end system begin toestablish or change. It may keep long time without any operation. However, theEPG information should be changed daily, weekly, or monthly. So the SI-EPGsystem supports program schedule import and export of many TXT and XMLformat to improve efficiency.Moreover, the SI-EPG system has lots of powerful functions, such as online editand offline edit, multi languages, word check, schedule censorship, etc. Specially,the system could support new mosaic navigation descriptors in which some ofour inventions have been adopted by lots of international companies.4.5 CAS & SMSCOMPUNICATE TECHNOLOGIES INC. 14ADD:No. 901-905, Block B ( Office Section) Maples International Center, No. 32 XizhimenNorth Street, Haidian District, Beijing 100082 P.R.C.Tel:+86 10 62272800 Fax:+86 10 62277908Website:www.compunicate.cn
  • 15. CTI-CAS system manages all subscribers, environment, accounts, andauthorization informations by means of distributed workstations, servers anddatabase. The CAS connects to scrambler with standard interface to sendauthorization message to the receivers.CTI-CAS core module includes EMM generator (EMMG) and ECM generator(ECMG). ECMG gets access criteria (AC) information and control word (CW)from the simulcrypt synchroniser (SCS) module of scrambler, then generatesencrypted entitlement control message (ECM) information and returns it to SCSby standard interface. EMMG generates encrypted entitlement managementmessage (EMM) from SMS database, then submits it to scrambler forbroadcasting. All transfer of the ECM, EMM is encrypted professionally for highsecurity.SMS module is another important module of CTI-CAS which has payment,distributing smart cards, query, print invoice, statics functions and so on. Allsubscribers’ information is managed by SMS which has kinds of interface withother system outside. For example, EPG interface, short message charginginterface, bank interface, etc.CTI-CAS supports channel, subject, level, event process, and PPV, IPPVfunctions, has flexible addressing, Bmail and on screen display (OSD) messagefunctions, etc. The standard system could support 3,000,000 subscribers, andcould be upgraded smoothly.CTI-CAS accords with international and national stardards completely. It hasopen interfaces for third party systems, has work well with many scramblers,BOSS systems and STBs in hundreds of projects all over the world.4.6 SummarySo the head-end solution is designed mainly with Compunicate products.
