Description

A person with low cost.
按，一般習用視訊之傳輸裝置４（如第４圖所示），係由一編碼器４１、一調變器４２、一I/Q單元４３、一混合單元４４及一升頻器４５所構成；當使用時係由編碼器４１將TS訊號傳輸至調變器４２，再由I/Q單元４３將調變之訊號加以轉換，而轉換號之訊號再由混合單元４４配合第一頻率４４１進行調變，最後再由升頻器４５配合第二頻率４５１之混波，而輸出高解析影像訊號。
雖然，上述習用視訊之傳輸裝置４可輸出一般影像訊號，並不是高解析影像訊號，且目前高解析影像訊號僅能將高解析影像訊號（HDMI/SDI）作近距離及點對點之傳輸（HDMI大約五公尺，SDI大約100公尺），因此，於運用上已無法符合實際之需求；然，若要應用於高解析度訊號之遠距離傳輸時（約一公里以上），則須採用SNG車或衛星進行傳輸，如此，不但會有結構複雜以及體積龐大之情形外，更會有使用成本極高之問題產生。
有鑑於此，本案之創作人特針對前述習用創作問題深入探討，並藉由多年從事相關產業之研發與製造經驗，積極尋求解決之道，經過長期努力之研究與發展，終於成功的開發出本創作「高解析視訊傳輸裝置」，藉以改善習用之種種問題。

Modulation, and finally the upconverter 45 cooperates with the second frequency 451 to output a high resolution image signal.
Although the above-mentioned conventional video transmission device 4 can output a general video signal, it is not a high-resolution video signal, and currently the high-resolution video signal can only transmit high-resolution video signals (HDMI/SDI) for short-distance and point-to-point transmission (HDMI is approximately 5 meters, SDI is about 100 meters), therefore, it can not meet the actual needs in application; however, if it is to be used for long-distance transmission of high-resolution signals (about one kilometer or more), SNG vehicles must be used.
