Abstract Along with the increasingly developed computer technology and the wide application of Internet, the use of Internet has been more and more diverse. The function of narrowband network that was limited in the transmission of texts and basic graphs cannot meet the needs of the transmission of multimedia which is consisted of audio, data, video, etc. Therefore, the broadband network has gradually become the mainstream of the network application. The objectives of this study are to discuss the technologies commonly applied in broadband network and to find out how the function of broadband network could be promoted in Taiwan. This study is an industrial policy research. The comparative analysis was conducted on the secondary data collected from both domestic and foreign sources. As shown by the statistics, the number of broadband subscribers has been increasing rapidly in both domestic and foreign areas. This reflects the rising demand of broadband. The conclusions of the study are as follows: 1. The government policy and the industry support make the number of broadband subscriber increase sharply. 2. ADSL and Cable Modem are the technologies commonly adopted among various countries. 3. The economy factor is the primary consideration in adopting the broadband technologies. 4. The content of network is the key factor to the popularity of broadband network. 5. The popularity of broadband network will promote the electronic commerce. There are five suggestions in this study: 1. To install a full optical-fiber network. 2. To accelerate the network into the Internet Protocol one. 3. To cultivate the software professionals. 4. To rationalize the fee of broadband network. 5. To implement the policy on speeding up the construction of broadband network. Key word: Internet, Broadband network, ADSL, Cable Modem

The purpose of this work is to assess and propose possible methods for increasing the transmission speed of the cable television distribution, concretely the UPC network in Brno. The first part of work collectively processes general knowledge and gives the reader into the issue. After that follows an analysis of TV cable networks UPC in Brno, especially view of data transmission. After familiarization with the physical aspect of the network is described data communications itself, including standard DOCSIS, respectively EuroDOCSIS. Particular attention is paid to factors that have effect on data transmission and speed. Benefit is the calculation of dividing ratio in different parts of the network and compared with the real load. As far as possible in the given work results of measurements with regard to the quality of the network. The last part is about how to increase speeds. Perspective solution is mainly a technology which is based on standard EuroDOCSIS 3.0, which introduces the concatenation of individual channels. Result of made tests of first cable modem EuroDOCSIS 3.0 confirms the very high speeds and currently preparedness for other major step in so long development of TV cable network.

鑒於寬頻網路是電子商務發展基石，各國無不積極規劃寬頻網路基礎建設，藉由技術昇級與整合，建構安全可靠的電子商務服務環境，吸引更多企業與消費者參與使用電子商務。ING Barings在2000年研究報告中指出，台灣未來寬頻網路服務市場營收可望在2004年達到773.3億之多，預計寬頻網路服務市場將隨著國際頻寬成本不斷降低而成長。 在行政院NII小組推動「三年三百萬人」寬頻上網目標後，根據資策會資訊情報中心統計，目前我國網際網路使用人口已經達到六百萬人，寬頻網路使用人口則已超過四十萬人。眾多市場競爭者中，有線電視業者由於擁有最後一哩及內容優勢，有助於發展整合性服務，成為進入市場優勢之一。 基於上述原因，本文研究目的旨在探討： （一）國外寬頻網路主要發展國家之市場現況。 （二）國內寬頻網路服務市場之發展現況。 （三）有線電視寬頻網路事業針對寬頻網路市場之整體佈局。 （四）有線電視寬頻網路事業在消費者資料庫上之運作現實。 （五）有線電視寬頻網路事業在企業關係利益人上之運作現實。 （六）有線電視寬頻網路事業在組織架構與傳播策略上之運作現實。 （七）有線電視寬頻網路事業在溝通執行要素上之運作現實。 透過文獻探討及深度訪談等方法，本文針對國外寬頻網路市場整體環境，以及國內兩大有線電視寬頻網路服務業者—東森國際網路與和信超媒體進行研究探討，得到下列結論： （一）政策及價格因素為影響各國寬頻網路服務市場能否迅速普及的關鍵因素。 （二）有線電視寬頻網路服務業者主要的威脅來自ADSL的競爭，以及HFC雙向網路佈建完成度的不足。 （三）母集團由上而下的推動，有助於國內有線電視寬頻網路事業的佈局。 （四）國內有線電視寬頻網路事業尚無行銷傳播專有消費者資料庫的規劃，而消費者資料庫蒐集方式與內容過於單向。 （五）國內有線電視寬頻網路事業依其市場利益點發展M & A策略，並視時間與事業定位轉換其企業關係利益人溝通策略。 （六）整合行銷跨功能管理過程及內部整合行銷系統，有助於國內有線電視寬頻網路事業進行傳播策略的整合。 （七）國內有線電視寬頻網路事業在傳播工具整合上具有良好成效，有助於品牌提昇與企業關係利益人的互動。 本研究並做出下列建議： （一）市場上，國內有線電視寬頻網路服務業者應該： 1.加速地方系統台的通路整合。 2.擴張綜合平台理念，提供綑綁式服務。 3.轉移並區分消費者市場。 （二）而就整合行銷觀點，國內有線電視寬頻網路服務業者應該： 1.改變公司行銷傳播的體制及優先順序。 2.建立新品牌接觸點與關係型的消費者資料庫內容。 3.儘快建立公司內部整合行銷系統。
