title="有線網(wǎng)絡">有線網(wǎng)絡，網(wǎng)絡建設和改造要直接向雙向化過渡”，意即數(shù)字化和雙向化同步完成。2.2009年廣電總局在《廣電總局關于促進高清電視發(fā)展的通知》中要求大力推廣高清頻道。目前8個省市開通了13套高清電視節(jié)目，高清將是不可逆轉的趨勢，而且推廣的速度會比想象的快。

      對于6300萬已經(jīng)完成了數(shù)字化平移單位完成雙向化的用戶，建議對其中部分有雙向互動點播需求的用戶換發(fā)雙向高清機頂盒，置換下來的單向機頂盒即可以給尚未完成數(shù)字平移的用戶使用，也可以給家庭第二臺電視使用。按照統(tǒng)計在類似于北京等城市，有80%的家庭擁有兩臺電視，可以一臺雙向高清，一臺單向標清。

      對于200萬已經(jīng)完成了數(shù)字平移和雙向改造開通的用戶（雙向覆蓋用戶已達3000多萬戶），考慮到這部分用戶經(jīng)濟基礎較好，是最有意愿也最有條件做雙向高清互動電視業(yè)務的，我們建議對于這部分視營銷策略決定是否盡快換發(fā)雙向高清機頂盒。換下來的雙向標清機頂盒可以給其余有雙向點播需求但無高清需求的用戶使用。

      目前業(yè)界有一種提法是采用單向機頂盒改造來做雙向互動電視業(yè)務。圖7-9比較幾種不同的實施方法，表2比較了三種方案的不同改造成本。可見當僅僅開展雙向互動電視業(yè)務的時候，已有單向機頂盒用戶的改造使用窄帶EOC+單向機頂盒的方案表面上有成本優(yōu)勢，但對于同時需要開寬帶和雙向互動電視業(yè)務的新用戶使用寬帶EOC+雙向機頂盒的成本是最低的。

      圖9

 

      表2三種方案的成本比較（單位：元）

      表3：某社區(qū)互動業(yè)務調查和上行帶寬需求a

      圖10詳細的示意了基于窄帶EOC的雙向互動點播實施方案。廉價的窄帶EOC方案一般選用的是ZigBee技術，我們知道ZigBee技術選用的頻點是315/433/868/915MHz，為了不和廣電現(xiàn)有的頻譜資源沖突，一般選用915MHz。另外根據(jù)衰減不同窄帶EOC方案的帶寬（共享）為0.6Kbps~500Kbps。從表3中可以看到對于雙向互動電視業(yè)務每戶所需帶寬需要規(guī)劃為50Kbps以開展點播和其他增值業(yè)務。但是窄帶EOC的帶寬最大只有500Kbps，這樣在同一時刻，一個窄帶EOC頭端（和ONU以及CATV光站均放置在光節(jié)點位置）僅能帶10戶，而我們知道目前一個光節(jié)點覆蓋的用戶至少為50戶。因此窄帶EOC的帶寬限制還是非常大的。同時我們從圖10中可以看出雙向互動點播平臺和EPON系統(tǒng)間的接口肯定是IP接口，而EPON是個二層透明傳輸系統(tǒng)，因此機頂盒232到IP信號的轉換必須由窄帶EOC來完成。一個理想的方案應該是機頂盒完成改造通過支持PPP來支持IP協(xié)議棧。窄帶EOC終端僅負責將串口PPP信號轉換成ZigBee在同軸電纜上傳輸，窄帶EOC頭端負責將ZigBee還原成PPP信號，再進行PPP終結成IP信號轉發(fā)上去或者轉換為PPPoE轉發(fā)上去。由此可見：為了互通，必須機頂盒廠家、窄帶EOC廠家和互動點播平臺以及廣電運營商四方充分配合，才有可能做到互通。對于單個地方廣電運營商涉及到如下問題：

      機頂盒廠家的意愿和配合度，是愿意重新改造單向機頂盒還是再賣一臺雙向機頂盒？

      機頂盒中間件和上層互動點播平臺的標準問題，能否協(xié)調？

      在機頂盒廠家和上層互動點播平臺之間標準協(xié)調好后還需要中間的窄帶EOC廠家的配合確保PPP協(xié)議和IP協(xié)議的正常轉換。保證互動平臺能夠和機頂盒之間對上。

      對于915M的窄帶EOC仍然需要考慮如何穿透放大器。

      另外單向機頂盒改造成雙向機頂盒還存在以下的問題：

      現(xiàn)有單向機頂盒是不是都留了標準RS232接口，可能存在有的機頂盒RS232接口僅留置在PCB上未引出機殼，也可能存在有的機頂盒雖然留出了RS232接口，但是為焊接RS232收發(fā)芯片電平為TTL電平；

      留了標準RS232接口，機頂盒底層軟件是否可以更改，因為該接口一般是給升級和調試使用的，不一定有改造成互動信道的技術可行性。

      不同機頂盒的RS232接口形式不一定一樣，特別是2,3,5以外其他針的定義可能不同。

      對于省級廣電運營商的技術部門還需要考慮到，下屬不同的地/市/縣的機頂盒CA、中間件、互動點播平臺多種多樣，一個地方就是一個標準，無法做到很好的統(tǒng)一，在此情況下，產(chǎn)業(yè)鏈上的各方很難配合好，無統(tǒng)一標準的情況下，將造成系統(tǒng)和設備廠家改造的意愿極小，實際的可操作性也極差。根據(jù)現(xiàn)有市場情況看，目前有窄帶EOC+單向機頂盒改造的地方，一般互動點播平臺+窄帶EOC+機頂盒都是一個廠家的，只有EPON可能是第三方的，造成了事實上的壟斷。基于以上的原因，我們認為窄帶EOC+單向機頂盒改造的方案基本上不可行的，或者說難度極大，除非是從上到下都是用一個供應商的產(chǎn)品。

      結論

      在當前的情況下，廣電可以選用IPQAM來部署雙向互動電視，從而可以節(jié)約下行IP帶寬供寬帶接入業(yè)務使用，同時考慮到可演進性和保護現(xiàn)有投資，應該選用同時支持IPQAM和IPTV的互動點播平臺。在處置現(xiàn)有單向機頂盒的問題上，首先明確幾個問題：先開展寬帶接入業(yè)務還是先開展雙向互動電視業(yè)務或是同時開展；何時規(guī)劃雙向高清互動電視，現(xiàn)有單向標清機頂盒有無升級軟件支持高清播放的可能性；雙向互動點播的滲透率能到多少，是整體轉移成雙向互動電視還是根據(jù)客戶需求來進行，寬帶的滲透率能到多少？一旦有寬帶需求的時候，一般不應該考慮窄帶EOC。窄帶EOC+單向機頂盒改造的方案存在產(chǎn)業(yè)鏈不好協(xié)調和及時協(xié)調好了在實際業(yè)務開通的時候也較繁瑣的問題。因此我們的建議還是采用寬帶EOC+雙向機頂盒的方案來部署雙改網(wǎng)絡，采用逐步置換的方式來解決存量單向機頂盒的問題。我們需要考慮到不是所有的用戶都有雙向互動的需求，同時需要考慮到同一家庭可能有兩臺及以上的電視機，可以一臺發(fā)展單向一臺發(fā)展雙向電視。再次對于尚未數(shù)字化的區(qū)域建議在成本允許的情況下，考慮數(shù)字化、雙向化、高清化一步到位，避免以后不斷的“翻燒餅”。考慮到高清互動電視的普及還有一個過程，可以當前要求機頂盒的硬件支持高清，當前可以僅支持標清，但是以后應有通過軟件升級的方式支持高清的能力。
