Method, device and system for obtaining rich media files

A device for obtaining a rich media file, comprising a receiving module, a rich media file processing module and a sending module, wherein

• the receiving module is configured to receive a download request, and output the received download request to the rich media file processing module;
• the rich media file processing module is configured to receive the download request, search for and obtain the rich media file according to a rich media file identifier carried in the download request, wherein the rich media file has been adjusted according to display screen information of a terminal device, and output the adjusted rich media file to the sending module;
• and
• the sending module is configured to send the rich media file output by the rich media file processing module to the corresponding terminal device according to a terminal device identifier;
• wherein the rich media file processing module comprises a rich media file storing unit, a rich media file searching unit, and a rich media file adjusting unit,
• the rich media file storing unit is configured to store rich media files;
• the rich media file searching unit is configured to receive the download request, search in the rich media files stored in the rich media file storing unit for the rich media file corresponding to the rich media file identifier, which is carried in the download request, and output the download request and the rich media file searched out to the rich media file adjusting unit;
• and
• the rich media file adjusting unit is configured to, according to the display screen information of the terminal device carried in the download request, adjust the received rich media file to enable size of the adjusted rich media file to be equal to size of display screen of the terminal device, and output the adjusted rich media file to the sending module;
• wherein the device further comprises a rich media file quality processing module configured to receive the rich media file output by the rich media file adjusting unit, obtain quality information about the rich media file, and determine whether quality of the rich media file is higher than quality requirements in quality information about the rich media file carried in the download request;
• when it is determined that the quality of the rich media file is higher than the quality requirements in the quality information about the rich media file carried in the download request, the rich media file quality processing module is further configured to process the rich media file to enable the quality of the processed rich media file to meet the quality requirements in the quality information about the rich media file carried in the download request, and output the processed rich media file to the sending module;
• when it is determined that the quality of the rich media file is not higher than the quality requirements in the quality information about the rich media file carried in the download request, the rich media file quality processing module is further configured to output the rich media file to the sending module.
