CPSE, world’s biggest security exhibition, was held from Oct. 29 to Nov. 1, 2015, in Shenzen, China.  This year, more than 1500 companies from 150 countries presented their latest security and surveillance products and solutions.
ccHDTV Alliance members A-Tec Subsystem, Inc. (www.a-tecsubsystem.com), Fuho Technology Co., Ltd. (www.vacron.com), and Ubiquity Smart Technology,  Inc.(www.ubiquitysmart.com) also jointly showcased their world leading DTV surveillance products.  The main themes of ccHDTV Alliance’s booth included multiple 4K videos over one coaxial cable and long-distance wireless surveillance cameras.  The members also exhibited solutions for wide-area, long-distance, and global surveillance system de-ployment.
The founding member of ccHDTV Alliance, ITE Technologies, Inc. (www.ite.com.tw), is a public fabless IC design company in Taiwan.  ITE’s ccHDTV chipset is the core of all DTV surveillance products.  ITE’s unique and robust digital transmission technology allows DTV surveillance products to send digital video and audio farther than 1km on a 5C-2V coaxial cable without any repeaters.  In addition, as many as 16 digital videos can be daisy-chained onto one single coaxial cable using inexpensive cable-TV power splitters.  These unique capabilities enable easy integration of DTV surveillance products into digital security systems, IoT, or cloud applications.

Multiple 4K Videos over One Coax:
Ultra HD DTV surveillance products showcased in CPSE include 4K DTV Cam and 4K DTV DVR.  DTV surveillance system is the only solution capable of simultaneously delivering multiple digital 4K videos over one coaxial cable.  Just like IP cameras, DTV surveillance cameras send digital video using digital transmission.  Thus, unlike analog and analog HD cameras, the video quality of DTV cameras is insensitive to the quality and length of the coaxial cable.

Long Distance Wireless Surveillance:
Because DTV cameras use coded OFDM for transmission, they can also be used for wireless surveillance.  DTV wireless products can achieve a transmission distance of up to 500 meters in an open space.  The products are good for places where cable installation is difficult, for example, seashores, mountain areas, construction sites, etc.

Smart Single Coax Transmission:
The reputed surveillance maker, Fuho Technology Co., is an early adaptor of the ccHDTV surveillance technology.  Fuho has manufactured many models of DTV Cams and DTV DVR’s using ITE’s chipset.  At CPSE, Fuho exhibited their DTV surveillance solutions for multiple 1080P@30fps and 1080P@60fps video transmission over a single 1 km 5C-2V coaxial cable without any repeaters.

Wide-Area and Long Distance Solutions:
A-    Tec Subsystems exhibited their DTV surveillance products with power over coaxial cable ( POC).  The power, video, and control signals are all multiplexed in one cable, thus enabling the so-called “one-cable solution.” This solution is best for places where electrical infrastructure is limited.  With 5C2V cable, the transmission distance can reach 1 km without any repeaters.  And if optical fiber is used, then the video can be transmitted as far as 50km.  This meets the security requirements for very large installation sites or very remote sites, such as farms, forests, and amusement parks.

Multinational Global Business:
UST Inc. demonstrated three killer products at the show: the 16-channel V100 Series, 32-channel P100 Series, and 64-channel E100 Series hybrid (IP+DTV) DVR’s.  These hybrid DVR’s constitute a suite of scalable products that matches the growth of companies from small to large and local to worldwide.

• 聯陽半導體發展ccHDtv緣起

在類比電視時代，CVBS(Composite Video Baseband Signal)是通用的信號格式，它也被用來當類比式監視系統(CCTV)的信號標準；當數位電視(DTV)逐漸取代類比電視成為全球趨勢，正如CVBS 作為類比式監視系統中的信號標準，以DTV技術來扮演同樣的角色於數位式監視系統中是理所當然的事。
聯陽半導體過去鑽研數位電視接收晶片已經有許多年，相關產品如可持式數位電視、NB dongle及機上盒的出貨量已經有幾千萬顆的實績，憑此技術基礎，聯陽思考憑藉以DTV技術來開發下一世代的數位式監視系統，經過幾年的研究，終於開發出以DTV技術為核心的數位式監視系統的全新規格，聯陽名之為『ccHDtv架構』。

• ccHDtv的核心技術及其優點

監視系統的組成，簡單來講就是由攝影機經由傳輸線傳送影像至後端的儲存設備(DVR)，然後作播放、儲存、回放以及其他應用功能。
ccHDtv (高清閉路電視系統)是一套針對攝影機、傳輸技術、儲存設備等新發展出來的高清影像監視系統 解決方案，利用數位電視技術將數位高清(High Definition)影像信號在同軸電纜、傳輸雙絞線上傳送，亦可以無線傳輸方式傳送；經實際證明，多路的1080p30或1080p60影像透過 ccHDtv技術可以容易地在一條傳統的3C2V/RG59同軸電纜上同時序列傳送，在無中繼器(repeater)輔助的情況下，傳輸距離仍可長達 500公尺。ccHDtv信號採用H.264壓縮技術經廣播式傳輸，不僅解決了CCTV閉路電視系統中高清影像傳輸的困難，同時也減輕儲存設備端的容量需 求，將使監視系統高清化在影像傳輸與後端儲存方面變得輕鬆容易，在工程安裝或操作使用上幾乎與傳統cctv系統一樣，對於想追求高畫質監控又不願重新佈線 或對網路穩定性有疑慮的使用者來說，ccHDtv將是一個最佳選擇。

• ccHDtv架構的主要特色：

1. 運用數位電視技術，家中數位電視某一頻道即可當作監視器用，非常平民化
2. 數位電視通訊協定的本質具有極強悍的抗雜訊與抗多路徑干擾的錯誤修正能力，因此類比監視系統升級到高清水準，仍可續用原來cctv老舊接頭與纜線，升級無須換線
3. 工程規劃布線安裝猶如傳統cctv系統的作業方式，迎合傳統安裝者
4. 提供通訊安全性之傳輸資料加解密功能(Data Encryption)以及避免訊號因被剪線而中斷之傳輸線双重化(Cable Redundancy)設計
5. 信號傳輸利用廣播式傳輸原理，運用不同載波，單一傳輸線可具有高通道容量，理論值可傳送超過100台高清的影像信號於單一傳輸線上
6. 無須輔助中繼器，傳輸距離即可長達500米以上
7. 支援聲音與控制回傳功能(Return channel)，配合DVR操控需求
8. 可支援多種傳輸介質，有線無線皆可用，利於布建規劃
9. 提供DTV轉接器，方便現存不同監控技術的攝影機無需汰換即可整合至ccHDtv架構
10. 提供DTV網路橋接器，可與網路接軌，利於ccHDtv與現存IP監控系統整合

• ccHDtv主要產品內容

DTV CAM：支援ccHDtv標準的攝影機
DTV HD DVR：支援ccHDtv標準的儲存設備(HD DVR)
DTV HUB：類比(CVBS) / DTV之轉換設備，讓既存的類比攝影機透過此HUB轉換升級為DTV CAM
DTV Gateway：DTV CAM橋接至IP Network，使DTV CAM就可成為現存IP監控系統的Device亦具有 IP CAM功能與網路接軌。

• 與其他監控系統之技術比較

隨著生活日益重視城市安全及家居安全，安全監控系統的技術發展推陳出新，諸如數位化後的DVR監控系統、網路攝影機(IP camera)的IP監控系統架構以及韓國業者主推的HDcctv架構(HD-SDI)。
安控產業是屬於封閉市場，大體而言，類比式cctv監控系統由於傳統安裝習慣的因素，目前在安空市場佔有率 仍然最大(約七成)，IP監控系統隨著網路應用環境及數位高清(high Definition)技術的發展，這幾年成長最快，但對於傳統閉路電視安裝者而言網路太過專業與複雜，維護成本過高，而且在多路高清攝影機的環境下，對 頻寬之穩定性亦存有疑慮，因此市場的拓展遇到傳統安裝習慣的心理阻力；至於韓國業者推出的HDcctv架構(HD-SDI)，傳輸線亦使用同軸電纜，傳輸 信號不壓縮，有即時性影像的優點，但其資料量大約是一般類比攝影機的數倍，相應的儲存設備需很大的容量，造成很大的成本負擔，這是很難普及至應用市場的真 正原因。

各監控系統比較表

聯陽整合許多自有技術，已完成開發ccHDtv相關晶片與應用設計，相較於其他監控技術，ccHDtv因具有許多架構上的特點而創造了整體的競爭優勢，對於需要全新的數位式監視系統或則類比式監視系統升級到高清水準的業者而言，ccHDtv是一套最佳的完整解決方案。

ccHDtv未來的市場機會:

監視系統走向高清數位化是城市安全未來必然的趨勢，ccHDtv同時符合市場趨勢與使用者習慣，未來看到的市場機會有三個層面：
1. 升級市場：全球既存攝影機有4億支，大部分類比攝影機需要升級到高清數位，ccHDtv是目前升級市場唯一最佳解決方案
2. 新建市場：除了能取代類比市場版圖又能與IP-base監視系統結合，以發展需要海量資料處理或複雜運算的高端應用市場產品，高低階產品市場皆涵蓋
3. 新增市場：有線電視數位化是各國趨勢，ccHDtv可運用於home security，增加有線電視業者在居家安全監視的附加服務，如果價格合理具誘因，應可以刺激廣大的家庭需求
