對(duì)于6300萬(wàn)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(duì)其中部分有雙向互動(dòng)點(diǎn)播需求的用戶換發(fā)雙向高清機(jī)頂盒,置換下來(lái)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(tái)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(tái)電視,可以一臺(tái)雙向高清,一臺(tái)單向標(biāo)清。
對(duì)于200萬(wàn)已經(jīng)完成了數(shù)字平移和雙向改造開(kāi)通的用戶(雙向覆蓋用戶已達(dá)3000多萬(wàn)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(dòng)電視業(yè)務(wù)的,我們建議對(duì)于這部分視營(yíng)銷策略決定是否盡快換發(fā)雙向高清機(jī)頂盒。換下來(lái)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(wú)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(lái)做雙向互動(dòng)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?jiàn)當(dāng)僅僅開(kāi)展雙向互動(dòng)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(shì),但對(duì)于同時(shí)需要開(kāi)寬帶和雙向互動(dòng)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3:某社區(qū)互動(dòng)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(dòng)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(duì)于雙向互動(dòng)電視業(yè)務(wù)每戶所需帶寬需要規(guī)劃為50Kbps以開(kāi)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(dòng)點(diǎn)播平臺(tái)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(hào)的轉(zhuǎn)換必須由窄帶EOC來(lái)完成。一個(gè)理想的方案應(yīng)該是機(jī)頂盒完成改造通過(guò)支持PPP來(lái)支持IP協(xié)議棧。窄帶EOC終端僅負(fù)責(zé)將串口PPP信號(hào)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(hào),再進(jìn)行PPP終結(jié)成IP信號(hào)轉(zhuǎn)發(fā)上去或者轉(zhuǎn)換為PPPoE轉(zhuǎn)發(fā)上去。由此可見(jiàn):為了互通,必須機(jī)頂盒廠家、窄帶EOC廠家和互動(dòng)點(diǎn)播平臺(tái)以及廣電運(yùn)營(yíng)商四方充分配合,才有可能做到互通。對(duì)于單個(gè)地方廣電運(yùn)營(yíng)商涉及到如下問(wèn)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(tái)雙向機(jī)頂盒?
機(jī)頂盒中間件和上層互動(dòng)點(diǎn)播平臺(tái)的標(biāo)準(zhǔn)問(wèn)題,能否協(xié)調(diào)?
在機(jī)頂盒廠家和上層互動(dòng)點(diǎn)播平臺(tái)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(dòng)平臺(tái)能夠和機(jī)頂盒之間對(duì)上。
對(duì)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(wèn)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(jí)和調(diào)試使用的,不一定有改造成互動(dòng)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(duì)于省級(jí)廣電運(yùn)營(yíng)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(dòng)點(diǎn)播平臺(tái)多種多樣,一個(gè)地方就是一個(gè)標(biāo)準(zhǔn),無(wú)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(wú)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(chǎng)情況看,目前有窄帶EOC+單向機(jī)頂盒改造的地方,一般互動(dòng)點(diǎn)播平臺(tái)+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?,我們認(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(shuō)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(lái)部署雙向互動(dòng)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(dòng)點(diǎn)播平臺(tái)。在處置現(xiàn)有單向機(jī)頂盒的問(wèn)題上,首先明確幾個(gè)問(wèn)題:先開(kāi)展寬帶接入業(yè)務(wù)還是先開(kāi)展雙向互動(dòng)電視業(yè)務(wù)或是同時(shí)開(kāi)展;何時(shí)規(guī)劃雙向高清互動(dòng)電視,現(xiàn)有單向標(biāo)清機(jī)頂盒有無(wú)升級(jí)軟件支持高清播放的可能性;雙向互動(dòng)點(diǎn)播的滲透率能到多少,是整體轉(zhuǎn)移成雙向互動(dòng)電視還是根據(jù)客戶需求來(lái)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(kāi)通的時(shí)候也較繁瑣的問(wèn)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(lái)部署雙改網(wǎng)絡(luò),采用逐步置換的方式來(lái)解決存量單向機(jī)頂盒的問(wèn)題。我們需要考慮到不是所有的用戶都有雙向互動(dòng)的需求,同時(shí)需要考慮到同一家庭可能有兩臺(tái)及以上的電視機(jī),可以一臺(tái)發(fā)展單向一臺(tái)發(fā)展雙向電視。再次對(duì)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(dòng)電視的普及還有一個(gè)過(guò)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(guò)軟件升級(jí)的方式支持高清的能力。
