商品描述
The “digital revolution” of the last two decades has pervaded innumerable aspects of our daily lives and changed our planet irreversibly. The shift from analog to digital broadcasting has facilitated a seemingly infinite variety of new applications―audience interactivity being but one example. The greater efficiency and compression of digital media have endowed broadcasters with a “digital dividend” of spare transmission capacity over and above the requirements of terrestrial broadcasting. The question is, who will use it, and how? Comparing the European experience with that of broadcasters elsewhere in the world, the author sketches the current status of international frequency management, quantifies the value of the “dividend” itself, analyzes the details of the analog-to-digital switchovers already completed, and posits what the future holds for the sector. As we grapple with new devices, inconceivable a mere generation ago, that allow us to access digital media instantly, anywhere and at any time of day, this book is a potent reminder that what we have witnessed so far may be just the first wavering steps along a road whose destination we can only guess at.
商品描述(中文翻譯)
「過去二十年的數位革命」已滲透到我們日常生活的無數方面,並不可逆轉地改變了我們的星球。從類比廣播轉向數位廣播促進了看似無限的新應用,觀眾互動只是其中一個例子。數位媒體的更高效率和壓縮能力使廣播商擁有了超出地面廣播需求的「數位紅利」的額外傳輸容量。問題是,誰將使用這些容量,如何使用?作者將歐洲的經驗與世界其他地區的廣播商進行比較,勾勒出國際頻率管理的當前狀況,量化「紅利」本身的價值,分析已完成的類比到數位的切換細節,並推測該領域的未來。當我們面對新設備時,這些設備在一代人之前是不可想像的,讓我們能夠隨時隨地即時訪問數位媒體,這本書強而有力地提醒我們,迄今為止所見的可能只是沿著一條我們只能猜測其目的地的道路的第一步。
