      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(diǎn)播需求的用戶換發(fā)雙向高清機(jī)頂盒，置換下來的單向機(jī)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(jì)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(biāo)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(dá)3000多萬戶）,，考慮到這部分用戶經(jīng)濟(jì)基礎(chǔ)較好，是最有意愿也最有條件做雙向高清互動電視業(yè)務(wù)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(jī)頂盒,。換下來的雙向標(biāo)清機(jī)頂盒可以給其余有雙向點(diǎn)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(jī)頂盒改造來做雙向互動電視業(yè)務(wù),。圖7-9比較幾種不同的實(shí)施方法,，表2比較了三種方案的不同改造成本?？梢姰?dāng)僅僅開展雙向互動電視業(yè)務(wù)的時(shí)候,，已有單向機(jī)頂盒用戶的改造使用窄帶EOC+單向機(jī)頂盒的方案表面上有成本優(yōu)勢,，但對于同時(shí)需要開寬帶和雙向互動電視業(yè)務(wù)的新用戶使用寬帶EOC+雙向機(jī)頂盒的成本是最低的。

      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(wù)調(diào)查和上行帶寬需求a

      圖10詳細(xì)的示意了基于窄帶EOC的雙向互動點(diǎn)播實(shí)施方案,。廉價(jià)的窄帶EOC方案一般選用的是ZigBee技術(shù),，我們知道ZigBee技術(shù)選用的頻點(diǎn)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(wù)每戶所需帶寬需要規(guī)劃為50Kbps以開展點(diǎn)播和其他增值業(yè)務(wù),。但是窄帶EOC的帶寬最大只有500Kbps,，這樣在同一時(shí)刻，一個(gè)窄帶EOC頭端（和ONU以及CATV光站均放置在光節(jié)點(diǎn)位置）僅能帶10戶,，而我們知道目前一個(gè)光節(jié)點(diǎn)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(shí)我們從圖10中可以看出雙向互動點(diǎn)播平臺和EPON系統(tǒng)間的接口肯定是IP接口,，而EPON是個(gè)二層透明傳輸系統(tǒng),，因此機(jī)頂盒232到IP信號的轉(zhuǎn)換必須由窄帶EOC來完成。一個(gè)理想的方案應(yīng)該是機(jī)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(fù)責(zé)將串口PPP信號轉(zhuǎn)換成ZigBee在同軸電纜上傳輸,，窄帶EOC頭端負(fù)責(zé)將ZigBee還原成PPP信號，再進(jìn)行PPP終結(jié)成IP信號轉(zhuǎn)發(fā)上去或者轉(zhuǎn)換為PPPoE轉(zhuǎn)發(fā)上去,。由此可見：為了互通,，必須機(jī)頂盒廠家、窄帶EOC廠家和互動點(diǎn)播平臺以及廣電運(yùn)營商四方充分配合,，才有可能做到互通,。對于單個(gè)地方廣電運(yùn)營商涉及到如下問題：

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

      機(jī)頂盒中間件和上層互動點(diǎn)播平臺的標(biāo)準(zhǔn)問題,，能否協(xié)調(diào)？

      在機(jī)頂盒廠家和上層互動點(diǎn)播平臺之間標(biāo)準(zhǔn)協(xié)調(diào)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(zhuǎn)換,。保證互動平臺能夠和機(jī)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(jī)頂盒改造成雙向機(jī)頂盒還存在以下的問題：

      現(xiàn)有單向機(jī)頂盒是不是都留了標(biāo)準(zhǔn)RS232接口,，可能存在有的機(jī)頂盒RS232接口僅留置在PCB上未引出機(jī)殼,，也可能存在有的機(jī)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(biāo)準(zhǔn)RS232接口,，機(jī)頂盒底層軟件是否可以更改，因?yàn)樵摻涌谝话闶墙o升級和調(diào)試使用的,，不一定有改造成互動信道的技術(shù)可行性,。

      不同機(jī)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(yùn)營商的技術(shù)部門還需要考慮到,，下屬不同的地/市/縣的機(jī)頂盒CA,、中間件、互動點(diǎn)播平臺多種多樣,，一個(gè)地方就是一個(gè)標(biāo)準(zhǔn),，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(biāo)準(zhǔn)的情況下，將造成系統(tǒng)和設(shè)備廠家改造的意愿極小,，實(shí)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(jī)頂盒改造的地方,，一般互動點(diǎn)播平臺+窄帶EOC+機(jī)頂盒都是一個(gè)廠家的,，只有EPON可能是第三方的，造成了事實(shí)上的壟斷,?；谝陨系脑颍覀冋J(rèn)為窄帶EOC+單向機(jī)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(gè)供應(yīng)商的產(chǎn)品。

      結(jié)論

      在當(dāng)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(wù)使用，同時(shí)考慮到可演進(jìn)性和保護(hù)現(xiàn)有投資,，應(yīng)該選用同時(shí)支持IPQAM和IPTV的互動點(diǎn)播平臺,。在處置現(xiàn)有單向機(jī)頂盒的問題上，首先明確幾個(gè)問題：先開展寬帶接入業(yè)務(wù)還是先開展雙向互動電視業(yè)務(wù)或是同時(shí)開展,；何時(shí)規(guī)劃雙向高清互動電視，現(xiàn)有單向標(biāo)清機(jī)頂盒有無升級軟件支持高清播放的可能性,；雙向互動點(diǎn)播的滲透率能到多少,，是整體轉(zhuǎn)移成雙向互動電視還是根據(jù)客戶需求來進(jìn)行，寬帶的滲透率能到多少,？一旦有寬帶需求的時(shí)候,，一般不應(yīng)該考慮窄帶EOC。窄帶EOC+單向機(jī)頂盒改造的方案存在產(chǎn)業(yè)鏈不好協(xié)調(diào)和及時(shí)協(xié)調(diào)好了在實(shí)際業(yè)務(wù)開通的時(shí)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(jī)頂盒的方案來部署雙改網(wǎng)絡(luò),，采用逐步置換的方式來解決存量單向機(jī)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(shí)需要考慮到同一家庭可能有兩臺及以上的電視機(jī),，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”,?？紤]到高清互動電視的普及還有一個(gè)過程，可以當(dāng)前要求機(jī)頂盒的硬件支持高清,，當(dāng)前可以僅支持標(biāo)清,，但是以后應(yīng)有通過軟件升級的方式支持高清的能力。
