[投影之窗消息]
中國人壽保險（集團）公司是國家大型金融保險企業，集團新大樓地處北京市西城區金融大街核心位置，屬金融街國際金融城范疇。中國人壽集團新大樓音視頻系統工程不僅要滿足集團內部業務培訓的需要，同時也是中國人壽集團對內外交流的窗口，所以，客戶從設備選型、系統設計到實施的要求都非常高。整個音視頻系統集視頻會議、投影及大屏顯示、會議發言、音響擴聲、信號切換等功能于一體，可滿足各種規模會議、培訓及小型娛樂活動的需要。各子系統音視頻設備全部由控制室統一控制并由AV信號傳到控制室統一處理；系統內部各房間的多媒體信號可以交互共享；建成后的系統平臺可提供各種音視頻信號的接入和輸出。
中國人壽集團技術部門深知要保障大樓音視頻系統穩定、安全并提供高品質的視聽效果，只考慮音視頻設備的性能是不夠的，作為系統信號傳輸“神經脈絡”的線纜和接插件也十分重要。考慮到大樓內會議室數量較多，信號點位密集，信源終端之間距離跨度較大，電磁干擾強烈等因素，因而高品質的線材和接插件成為本項目的首選。整個大樓AV系統設備基本采用了國際主流廠商設備，包括專業音箱、高清攝像機、專業投影機,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線材，以保障整個系統較高的性能、完美的音視覺體驗。佳耐美公司為此項目提供的線材基本涵蓋了佳耐美主要AV產品，包括RGBH信號傳輸電纜V5-5CFB、YUV分量信號纜V3-5CFB、VGA信號電纜V5-1.5C、數字同軸電纜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.
