The audio format is decompressed, or includes performing a corresponding decoding action, so that the audio can be played by the built-in speaker, or the external speaker 813 in this example, through the audio processing unit 804, especially by streaming. the

In terms of video processing technology, the device 80 may be provided with a video processing circuit in another embodiment, such as a video processing unit 806 electrically connected to the microprocessor 801, and the video processing unit 806 is a video processing unit. The main circuit includes performing operations such as video decoding and decompression, and can generate corresponding data according to the supported video format for broadcasting. After the video is converted to an image, it can be displayed on an external display 815 . the

To sum up, the mobile data processing device proposed by the utility model can connect at least two external storage media, and can perform data transmission between different external storage media without occupying the network between the device and other devices. Bandwidth, and provide a variety of data access services through a variety of storage functions provided by the device, including the ability to play audio or/and video generated by wireless terminal devices connected to the near end. the

But the above description is only the preferred feasible embodiment of the utility model, and therefore it does not limit the protection scope of the claims of the utility model, and all the equivalent structural changes made by using the specification of the utility model and the contents of the accompanying drawings are all the same. It is hereby declared that it is included in the protection scope of the present utility model. the
