    • A media player (100) coupled to a network (80) contains a processor (110), non-volatile memory (120), volatile memory (130), a driver (140), an input port (150) and an output port (152). The media player (100) receives a media file (90) over the network (80) that contains an encoded media stream (94) and a universal decoder (92). The player's processor (110) converts or translates (or otherwise generates) the universal decoder into a player-specific decoder (132) which may differ from the universal decoder. A library of routines (124) stored in the non-volatile memory (120) is used to create the player-specific decoder (132). The media stream (90) downloaded to the media player (100) may comprise audio, video, or any other desired type of media. In this manner, each media player (100) can generate a decoder (132) that differs, not only from the universal decoder (92), but may also differ from other media players thereby alleviating the burden on the media source from having to download the encoded media with a decoder specific to the target media player.
    • 耦合到网络(80)的媒体播放器(100)包含处理器(110),非易失性存储器(120),易失性存储器(130),驱动器(140),输入端口(150)和输出端口 (152)。 媒体播放器(100)通过包含编码媒体流(94)和通用解码器(92)的网络(80)接收媒体文件(90)。 播放器的处理器(110)将通用解码器转换或转换(或以其他方式生成)到与通用解码器不同的播放器专用解码器(132)中。 存储在非易失性存储器(120)中的例程库(124)用于创建播放器专用解码器(132)。 下载到媒体播放器(100)的媒体流(90)可以包括音频,视频或任何其它所需类型的媒体。 以这种方式,每个媒体播放器(100)可以生成不仅来自通用解码器(92)但不同于其他媒体播放器的解码器(132),从而减轻了媒体源不必下载的负担 具有特定于目标媒体播放器的解码器的编码媒体。
