使用 hifree 應用程式，觀察其播放媒體的方式，分別使用哪種協議。
一、選擇"頻道"撥放
其作法是直接下載整首歌曲後播放，並非使用RTSP協議。
1. hifree 先向伺服器取得歌曲清單
[truncated] GET /get_channel_song.php?enc=u&oenc=kkt&hw_vendor=kkbox&hw_model=fttx&sid=V0000a.739500000000000000000000000000AbED05335PoQDS001Fn6Jjc9e1&ksid=V0000a.739500000000000000000000000000AbED05335PoQDS001Fn6Jjc9e1&kkid=KKBOX-VZQSCFAG
User-Agent: KKBOX air(Get Song List)\r\n
Host: api.kkbox.com.tw\r\n
Cookie: PPHPSESSID=267759049478910113475\r\n
2. hifree 要求取得使用者選擇的歌曲(此時並沒有使用 RTSP)
[truncated] GET /kkbox/cht/v1/NSP9rz404KNLZIR1GHEux0P4.wma?enc=u&oenc=kkt&hw_vendor=kkbox&hw_model=fttx&sid=V0000a.739500000000000000000000000000AbED05335PoQDS001Fn6Jjc9e1&ksid=V0000a.739500000000000000000000000000AbED05335PoQDS001Fn6Jjc9e
Connection: Keep-Alive\r\n
Host: 210.61.218.49\r\n
3. 伺服器回歌曲
HTTP/1.1 200 OK\r\n
Content-Length: 4651681\r\n
Content-Type: audio/mpeg\r\n
Content-Diposition: attachment; filename="311701_2_r2_v1.mp3"\r\n
二、選擇"廣播" 撥放
其作法是使用 HTTP Get 方式，利用 chunked encoding 方式，透過多個HTTP封包，取得欲撥放的資料。整個過程實際上是根據 Windows Media HTTP Streaming Protocol Specification 運作。
1.試著使用 RTSP over TCP 連線，試了三個不同的 IP 都失敗
2. 利用 HTTP 取得封包( [MS-WMSP])

三、選擇"MV" 撥放，此處也是使用 [MS-WMSP] 的協議
