1引言

本文針對中國廣電的服務對象提出了相應的業務，并抽象出相應的能力，希望在未來的業務規劃上提供更多思路。在當前融合媒體與大視頻發展的背景下，傳媒與視頻相關技術正在飛速發(fa)展、迭代(dai)，傳(chuan)統廣(guang)電面(mian)臨(lin)諸多(duo)挑戰。面(mian)對即將到來(lai)的(de)(de)(de)5G時代(dai)，以及超高清內(nei)容(rong)制播(bo)(bo)和(he)多(duo)融合業(ye)務（網(wang)(wang)(wang)紅直(zhi)(zhi)播(bo)(bo)、融合直(zhi)(zhi)播(bo)(bo)等(deng)(deng)）的(de)(de)(de)需求(qiu)，4K、8K、VR、AI等(deng)(deng)內(nei)容(rong)的(de)(de)(de)出現(xian)對直(zhi)(zhi)播(bo)(bo)帶(dai)寬提出了(le)更高的(de)(de)(de)要求(qiu)，現(xian)有的(de)(de)(de)DVB頻點資源(yuan)已無法滿(man)足，客戶對終端機頂盒的(de)(de)(de)多(duo)樣化升級要求(qiu)越來(lai)越高，傳(chuan)統的(de)(de)(de)廣(guang)電制播(bo)(bo)流程及DVB直(zhi)(zhi)播(bo)(bo)方式已經無法適應日益更新的(de)(de)(de)需求(qiu)。目(mu)前，廣(guang)電雙向化、光纖化改造(zao)取得全(quan)面(mian)進展，城域(yu)網(wang)(wang)(wang)建設也頗具(ju)規模，具(ju)備開(kai)展IP化直(zhi)(zhi)播(bo)(bo)的(de)(de)(de)網(wang)(wang)(wang)絡(luo)條件(jian)。同時，已建成的(de)(de)(de)門戶、CDN、內(nei)容(rong)運營等(deng)(deng)系統能靈(ling)活改造(zao)接入(ru)IP化改造(zao)中，全(quan)IP化網(wang)(wang)(wang)絡(luo)直(zhi)(zhi)播(bo)(bo)的(de)(de)(de)發(fa)展已是大(da)勢所(suo)趨。
