[投影之窗消息]
中國(guó)人壽保險(xiǎn)（集團(tuán)）公司是國(guó)家大型金融保險(xiǎn)企業(yè)，集團(tuán)新大樓地處北京市西城區(qū)金融大街核心位置，屬金融街國(guó)際金融城范疇。中國(guó)人壽集團(tuán)新大樓音視頻系統(tǒng)工程不僅要滿足集團(tuán)內(nèi)部業(yè)務(wù)培訓(xùn)的需要，同時(shí)也是中國(guó)人壽集團(tuán)對(duì)內(nèi)外交流的窗口，所以，客戶從設(shè)備選型、系統(tǒng)設(shè)計(jì)到實(shí)施的要求都非常高。整個(gè)音視頻系統(tǒng)集視頻會(huì)議、投影及大屏顯示、會(huì)議發(fā)言、音響擴(kuò)聲、信號(hào)切換等功能于一體，可滿足各種規(guī)模會(huì)議、培訓(xùn)及小型娛樂(lè)活動(dòng)的需要。各子系統(tǒng)音視頻設(shè)備全部由控制室統(tǒng)一控制并由AV信號(hào)傳到控制室統(tǒng)一處理；系統(tǒng)內(nèi)部各房間的多媒體信號(hào)可以交互共享；建成后的系統(tǒng)平臺(tái)可提供各種音視頻信號(hào)的接入和輸出。
中國(guó)人壽集團(tuán)技術(shù)部門(mén)深知要保障大樓音視頻系統(tǒng)穩(wěn)定、安全并提供高品質(zhì)的視聽(tīng)效果，只考慮音視頻設(shè)備的性能是不夠的，作為系統(tǒng)信號(hào)傳輸“神經(jīng)脈絡(luò)”的線纜和接插件也十分重要。考慮到大樓內(nèi)會(huì)議室數(shù)量較多，信號(hào)點(diǎn)位密集，信源終端之間距離跨度較大，電磁干擾強(qiáng)烈等因素，因而高品質(zhì)的線材和接插件成為本項(xiàng)目的首選。整個(gè)大樓AV系統(tǒng)設(shè)備基本采用了國(guó)際主流廠商設(shè)備，包括專(zhuān)業(yè)音箱、高清攝像機(jī)、專(zhuān)業(yè)投影機(jī),等等。
在連接線材及接插件方面，則采用了日本佳耐美公司廣播級(jí)線材，以保障整個(gè)系統(tǒng)較高的性能、完美的音視覺(jué)體驗(yàn)。佳耐美公司為此項(xiàng)目提供的線材基本涵蓋了佳耐美主要AV產(chǎn)品，包括RGBH信號(hào)傳輸電纜V5-5CFB、YUV分量信號(hào)纜V3-5CFB、VGA信號(hào)電纜V5-1.5C、數(shù)字同軸電纜L-5CFB、四芯星絞音頻線L-4E5AT、音箱電纜2S9F、插頭及音視頻跳線盤(pán)等。
Audio and Video system of new PICC office tower
PICC is one of large state-run insurance enterprises in
China. Its new office tower is located at the central area of the
financial street in Xicheng District of Beijing. PICC equipped a
sophisticated audio and video system to support not only its internal
training purpose, but also presentation functions in other events like
video conferences, etc. The AV system includes AV facilities in
conference rooms, projection system, big screen display, professional
audio, signal exchange system, etc. One central control room manages all
AV signals processing and transmission. Multimedia signals can be shared
among every sub-system and each individual room. The final AV platform
also provides various input and output interfaces of audio and video
signals.
PICC technical department understands well that high performance of
AV equipment is not enough to support a reliable and secured audio and
video system of high quality. As the ‘blood vessel’ of an AV system,
cabling shall be put on the same priority as it for AV equipment to be
connected. Considering factors such as big quantity of conference rooms
and AV interfaces, long distances between signal sources and its
terminals, and also complicated situation of electric-magnetic
interferences, etc, the high quality of cabling is a must to match the
performance of its AV equipment like professional speakers, HD video
camera, and professional projectors, etc. All AV cabling including
cables and connectors finally went to Canare, a Japan-based manufacturer
in professional AV cabling with broadcasting quality. Canare company
provided RGBHV cable (V5-5CFB), YUV component signal cable (V3-5CFB),
VGA cable (V5-1.5C), digital video cable (L-5CFB), mic cable of star
quad (L-4E5AT), speaker cable (2S9F), various connectors, and
audio/video patchbays in the AV system of PICC new office tower.
