| Abstract: | 智慧型手機的功能日漸強大，而我們希望能夠利用智慧型手機普及的趨勢，實作一個能夠讓眾人互動的電台應用程式，IRIS:互動式2.0手機廣播電台應用程式。聽眾能夠透過網路與在廣播電台上建立節目的分享者連線，來收聽分享者目前正在播放的音樂歌曲。在此，我們將分享者稱作是“網路DJ”，聽眾可以透過頻道來選擇喜歡的電台。而原本僅能收聽音樂的使用者則可以隨時選擇成為“網路DJ”，並且經營屬於自己風格的網路電台。
“網路DJ”除了單純分享音樂外，也可以透過手機上的麥克風收音來主持節目。如果聽眾對“網路DJ”有任何回應，還可以使用Call-in進行網路電話型式的網路對談。
然而因為手機本身有網路傳輸的問題。手機上網時通常位在網路交換器背後，因為使用虛擬位址以至於彼此之間無法直接進行連線。並且當系統內有多名“網路DJ”同時進行放送時，將會有多條不同的聲音串流來爭奪伺服器網路的頻寬，並且造成提供服務的伺服器負擔。為了解決這些問題，我們要優先處理無法直接連線的困境，接著並引入了簡單的負載平衡方式來分散聽眾，進而解決伺服器網路的瓶頸。最後，我們作出這個廣播電台應用程式並且有令人滿意的運行結果。
Smartphones are more powerful and popular nowadays. We hope to utilize smartphones to develop an interactive radio application, IRIS: Interactive 2.0 Radio System on the Internet over Smartphone. Using this App, a user can create a channel and become a “DJ” to provide the show. Otherwise, he/she can be the audience to choose the radio channel that his/her favorite DJ hosts.
The DJ not only provides the music but also can anchor by the microphone on the smartphone. If the audience has any feedback to the DJ, he/she can make a call-in to talk interactively with DJ by the VoIP service.
To this end, there is a problem on network transmission over smartphone. Because smartphones are usually behind NAT, it would cause no one to be able to connect to each other directly due to private IPs. Besides, when many DJ provide their shows on the air, it might cause many streaming relays to overload the Server. Therefore, we need to solve the NAT problem and alleviate the loading on the server by deploying a load balancing architecture. The App and the radio system were developed and the results were satisfactory. |
