    • The present invention is directed to a system and method which allows highly compressed data files to be expanded in a standalone decoder having an output at least 80 times larger than the compressed input. In one embodiment, a universally available interface is used to transport encoded media from a host PC to a decoder external to the PC for expansion and presentation as a HD display image. In one embodiment, a USB port of the user's PC (or other storage device) is used to transport data at a rate of between 0.3 Mbit/sec and 5 Mbits/sec for expansion into a robust HD signal of up to about 3Gbits/sec or higher. In other embodiments, provision is made for reducing the decompressed expanded data file to below 480 Mbits/sec so as to accommodate retransport of the decompressed file back to the PC or storage device for temporary storage or display.
    • 本发明涉及一种系统和方法,其允许在具有比压缩输入大至少80倍的输出的独立解码器中扩展高度压缩的数据文件。 在一个实施例中,普遍可用的接口用于将编码的媒体从主机PC传送到PC外部的解码器,用于作为HD显示图像进行扩展和呈现。 在一个实施例中,用户PC(或其他存储设备)的USB端口用于以0.3Mbit / s和5Mbits / sec之间的速率传输数据,用于扩展到高达约3Gbits /秒的鲁棒HD信号 或更高。 在其他实施例中,提供了将解压缩的扩展数据文件减少到低于480Mbits / sec,以便将解压缩的文件的重新转发回PC或存储设备进行临时存储或显示。
