感覺很拗口，因為是機器翻譯的？＠＠

實際上要講的是 What is MTP (Media Transfer Protocol) ?

wiki : Media Transfer Protocol

The Media Transfer Protocol is a devised set of custom extensions to the Picture Transfer Protocol (PTP).

Media Transfer Protocol supports the transfer of music files on digital audio players and movie files on portable media players.

from Definition of "Media Transfer Protocol"

The Media Transfer Protocol is a system devised by Microsoft that allows for the synchronization of media files between a personal computer and a device such as a cell phone or MP3 player.

所以看來是跟微軟有關的

那去google group上發問

看到這個

Is there any plan to support MTP protocol in Donut or later?

所以G1上應該是有3rd party來做MTP, Google android project open source的部份不支援MTP !

update 2011

Android 3.0 開始在Nvdia的平台上開始有支援MTP嚕

不過MTP跟adb之前還有一些問題，

所以不建議同時開始MTP以及adb
