Of: Chengdu Conte Group Long Yongqing Introduction Broadcasting TV Cable Network Operation As a inhabitant report complement remodel as well as changes to a citation of industrialization, wire networks will progressively turn a IT industry, vast network operators. Broadcasting Cable Network Industry reform, faced with good opportunities as well as many challenges. Challenges from communications operators; with a countries in a investigate Standard AVS R & D as well as H.264 Technology, in sold a good advantages of H.264 technology, telecommunications operators can operate existent interpretation network for video value-added commercial operation services? IPTV (Ie Network TV ), IPTV duty of a tangible promote graduation over a years VOD . From air wave as well as air wave inner challenges; heavenly body promote Digital TV And wireless digital TV to network as well as low price advantages, is firm to mangle a wire network to entrance a user’s elementary Monopoly . Industrial worth is to concede wire networks to find growth upon their own power. Wired, wireless as well as heavenly body delivery of 3 co-exist, contingency fool around their particular advantages, combining a core of their Competition Force. 1 a accumulation of delivery methods, advantages as well as stipulations (1) approach promote heavenly body mode Nationwide commercial operation a lowest price (especially for a mountain), as well as can fool around promote upon inhabitant air wave as well as air wave resources upon a advantages, as Video Compression Technology, partial of a heavenly body transponder will be equates to to entirely encounter a vast national module upon a series of users requirements. DBS (access users) equates to singular one-way promote delivery mode as well as high-definition digital TV commercial operation difficulty to lift out vast interpretation streams (if in suitability with a H.264 standard, we can lift HDTV). (2) wireless digital air wave broadcasts Certain area lonesome by a lowest cost, wireless air wave as well as air wave is report a initial endless operate of transmission, as analog TV frequencies to apparatus constraints, a past twenty years progressively wire network transposed in a cities as well as towns. With video application record growth (in suitability with a H.264 standard, a 8Mhz earthy bandwidth TV channels can additionally promote some-more than 32 standard-definition television), TVB channel delivery with a multi-channel digital air wave is not usually possible, though additionally has entrance Flexible good advantage. Terrestrial air wave entrance process is additionally singular by a categorical issues one-way promote delivery (if approaching to be used bi-directional transmission, contingency be in accord with Planning Base station, as well as this is air wave TV hire Stop building a whole of a utterly opposite theory). (3) alternative communications networks carried out underneath conditions of IPTV in broadband Although a H.264 video application record to await interpretation entrance regulating 512kbps-1Mbps network of IPTV, though there have been still a critical necessity of network bandwidth, earthy as well as technological issues of network latency; as well as some-more than a single machine, module source as well as network entrance Entry costs (system costs) as well as so on. These problems shorten a graduation of IPTV applications. (4) Cable air wave Network entrance mode To HFC wire network, represented by two-way delivery in sequence to grasp peculiarity conditions, both air wave as well as air wave networks as well as a magnitude of abounding interactive information exchnage network edge, can be carried out in sequence to variegate their business, personalized use with a combined worth of a many rival business, generally for high-volume difficulty of tall clarification digital promote TV, video telephony, or interactive VOD as well as alternative high-volume commercial operation conduct. Internet entrance costs aloft than a heavenly body networks as well as TV networks, reduction than a Ethernet as well as disfigured span networks, a pass is how a HFC network to lift out a accumulation of commercial operation as well as personalized service, which is to fool around a wire core cunning key. 2 HFC two-way network, a core competitiveness (1) HFC two-way network await individualized mandate of users, it is heavenly body as well as TV networks do not have singular features, which encounter a particular mandate of users share vast commercial operation market. (2) HFC two-way network entrance with good magnitude (bandwidth) resources to any visual node 500 of a resource, for example, a initial net of about 400M (50 8M channels) organised a one-way promote TV (including digital TV) programs, a superfluous we estimate 320M (40 8M channels) for downlink interpretation delivery resources, can encounter some-more than 2000 opposite users upon direct IPTV real-time mandate (more than a single machine), a uplink apparatus is larger than a in effect 40M (about twelve 3.2M channels), a common interpretation bandwidth larger than 120Mbps (high-quality network with 64QAM uplink, a tangible apparatus is larger than 200Mbps), whilst assembly a ubiquitous conditions underneath which some-more than 500 users online Game (Uplink apparatus beyond is a largest commercial operation network games), VOIP , Video telephones as well as alternative network services. (3) HFC two-way network conditions, CMTS as well as Modem await tolerable enlargement of a user, a channel share of technical superiority, have been a network operators underneath a conditions of fast technological development, shortening investment, show off increase core competitiveness. This is a Ethernet or disfigured span network switching apparatus do not have a analogous advantage. (4) HFC two-way network building a whole costs have been reduce (relative to metro Ethernet as well as disfigured span Cable Net), a furious as well as not usually a sell of equipment, delivery apparatus (as against to Ethernet), tall reliability, easy to maintain. (5) HFC two-way network is a “One network as well as multi-function” basis, which is “triple play”, a network await a doing of TV, voice as well as interpretation services for a farrago of content, personalized service. Business competitiveness is a core competitiveness. (6) HFC two-way record continues to rise network harmony is improved than a alternative communications network, is a standard multi-platform coexistence vigilance to grasp a building a whole of a single (or a) network, can await a growth of a accumulation of commercial operation . This indicate Operate Content government as well as ever-changing commercial operation conditions, generally for real. 3 how to raise a core competitiveness of wire networks (1) Two-way Network A peculiarity two-way network is a foundation, is a premise. There is no approach of not all. Would be reduction in effect though quality. (2) government of smart Improve network government to grasp government of intelligence, or can not conform to commercial operation diversification, though can not encounter a personalized service. Radio as well as air wave networks benefaction elementary domicile monthly by a miss of user government user apparatus government is intensely critical which a simple government functions, though a miss of a multi-service management
