Description
本創作係關於一種電視訊號傳輸系統，特別是一種將原先分離的衛星電視訊號及地面電視訊號結合並透過單一光纖纜線傳輸電視訊號之光纖傳輸系統。The present invention relates to a television signal transmission system, and more particularly to an optical fiber transmission system that combines originally separated satellite television signals and terrestrial television signals and transmits television signals through a single optical fiber cable.
現今，一般的電視用戶，想要同時收看衛星訊號的電視節目與地面訊號的電視節目，需要先安裝一種碟型衛星電視天線及地面電視接收天線，以接收衛星電視廣播訊號與地面電視廣播訊號，再透過具有地面電視訊號輸入端的低雜訊放大降頻器，將衛星電視廣播訊號放大後，再降頻至中頻，並結合地面電視訊號在輸出端輸出，最後透過同軸電纜將衛星電視中頻訊號及地面電視訊號傳輸至用戶端。Nowadays, in general, TV users who want to watch satellite TV programs and terrestrial TV programs at the same time need to install a satellite TV antenna and a terrestrial TV receiving antenna to receive satellite TV broadcast signals and terrestrial TV broadcast signals. Then, through the low noise amplification downconverter with the ground TV signal input terminal, the satellite television broadcast signal is amplified, then down-converted to the intermediate frequency, and combined with the terrestrial television signal output at the output end, and finally the satellite television intermediate frequency is transmitted through the coaxial cable. Signals and terrestrial TV signals are transmitted to the client.
然而，利用同軸電纜傳輸的衛星電視中頻訊號及地面電視訊號，可以傳輸的距離，會受到同軸電纜較高的電纜損耗影響，對於集合住宅單位(Multi-Dwelling Unit，MDU)，例如公寓、大廈或社區等使用公共電視接收天線的多用戶住宅環境，則需要裝置中繼放大器才能將衛星電視中頻訊號及地面電視訊號傳輸至距離衛星電視天線與地面電視接收天線較遠端的用戶。However, satellite TV IF signals and terrestrial TV signals transmitted over coaxial cable can be transmitted at a distance that is affected by the high cable loss of the coaxial cable. For Multi-Dwelling Units (MDUs), such as apartments and buildings. Or a multi-user residential environment using a public television receiving antenna, such as a community, requires a relay amplifier to transmit satellite television IF and terrestrial television signals to users farther away from the satellite TV antenna and the terrestrial TV receiving antenna.
基於衛星電視訊號雙極性與寬頻帶，例如垂直極化及水平極化或左旋極化或右旋極化，寬頻帶在10.7~12.75兆赫茲之特性，以傳統通用型低雜訊放大降頻器(Universal LNB)為例，需將衛星電視訊號放大後，再降頻成為四組衛星電視中頻訊號，並利用四組同軸電纜以傳輸至集合住宅單位中的用戶端分配使用。利用此習知的應用與設置方式，在訊號到達收視端與用戶端之前，還需要設置許多個分歧器(Tap)、分路器(Splitter)與多工切換器(Multi Switch)。Based on the characteristics of satellite TV signal bipolar and wideband, such as vertical polarization and horizontal polarization or left-hand polarization or right-hand polarization, the wide frequency band is 10.7~12.75 MHz, with the traditional general-purpose low noise amplification downconverter. (Universal LNB), for example, the satellite TV signal needs to be amplified, then down-converted into four sets of satellite TV IF signals, and transmitted to the user terminals in the collective residential unit by four sets of coaxial cables. With this conventional application and setting method, before the signal reaches the viewing end and the user end, it is also necessary to set a number of taps, splitters and multiplex switches (Multi Switch).
有鑑於此，在集合住宅單位多用戶使用環境中，若使用同軸電纜傳輸衛星電視中頻訊號及地面電視訊號，考量同軸電纜較高的電纜損耗與衛星電視訊號雙極性與寬頻帶的特性，需要建置多個同軸電纜、中繼放大器、分歧器、分路器與多工切換器，此衛星電視收視系統的設置不僅複雜，且此一系統維護不易。因此，為了以簡單的方式，針對集合住宅單位中多用戶的應用，本發明結合了衛星電視廣播訊號及地面電視廣播訊號的電視訊號之光纖傳輸系統。In view of this, in the multi-user environment of the collective residential unit, if the coaxial cable is used to transmit the satellite TV IF signal and the terrestrial TV signal, considering the higher cable loss of the coaxial cable and the characteristics of the bipolar and wideband of the satellite TV signal, The installation of multiple coaxial cables, relay amplifiers, splitters, splitters and multiplexers, the installation of this satellite TV viewing system is not only complicated, but also the maintenance of this system is not easy. Therefore, in a simple manner, for a multi-user application in a collective residential unit, the present invention combines a fiber-optic transmission system for a television signal of a satellite television broadcast signal and a terrestrial television broadcast signal.
