數位化帶來公共電視經營新契機，同時實踐知識社會的價值觀。在原有的節目播出頻寬外，公共電視可以提供更多的頻道、資訊、互動軟體、多媒體功能。然而，究竟如何的服務項目能促進公民社會的發展，取決於該國公視的體質、媒體的生態、以及新時代教育內涵的需求。證諸先進民主國家發展趨勢，取向選擇之依據主要在於有線電視與網際網路之普及度；高者，公共電視將發展互補的數位教育功能；低者，公共電視則可開發新的電視立基市場，並與前者競爭。臺灣公共電視之體質不及強勢的歐洲公共電視，但是節目政策也不同於美國的教育方針，因此臺灣的模式可以學習歐洲如何開發教育娛樂創新頻道，並同時效法美國電視產業尋求策略聯盟的彈性，以使教育資源可以在未來各種數位平臺上流通，普及地促進文化公民的福利。

Thanks to digitization, a new vision entitled to public service broadcasting (PSB) and enhanced the value of knowledge in new economy. PSB could provide the multichannel program, information, interactive software, multimedia content along the extra spectrum other than the normal program on a single channel. However, whether the value of education is tenable by developing PSB digital service, is depended on matching the existing accountability of public service, media environment with the demand of new approaches. Based on the facts of advanced industrialized countries, the approach adopted is greatly decided by the popularity and coverage of cable and internet services. For the highest usage rate of former services, PSB should position itself as a complementary broadcaster; for the lowest rate of them, PSB could form a niche market of its strength, then move to compete with other players. It was not likely to achieve such strength by PSB in Taiwan, compared to the works of European public broadcasters. Neither should Taiwan develop a distance education program following U.S. PBS due to different origins. A Taiwan model could lauch edutainment channel in an innovative way, also flexibly build strategic alliances with different platforms to circulate educational materials widely. It is an eclectic approach to contribute the cultural citizenship in Taiwan during 21st Century.
