Method, system and device for playing streaming media

A system for playing streaming media, comprising:

• at least one computing device or integrated circuit module, configured to implement:
• a determining module, adapted to obtain information of a media file, which comprises an identification of the media file and a URL of the media file, and to determine at least two storages storing the media file by searching a network for the at least two storages according to a preset first correspondence relationship between the identification of the media file and information of the storages;
• a processing module, adapted to:
• test connection speeds of the determined at least two storages;
• determine a storage of the at least two storages having a connection speed larger than a first threshold;
• obtain media streaming data corresponding to the media file from the storage;
• a playing module, adapted to play the obtained media streaming data;
• and
• an adjusting module, adapted to adjust the media streaming data corresponding to the obtained media file;
• wherein establishing the first correspondence relationship between the identification of the media file and the information of the storages comprises:
• allocating a unique identification to the media file;
• obtaining information of the storages storing the media file;
• and
• forming the first correspondence relationship between the identification of the media file and the information of the storages;
• wherein the allocating a unique identification comprises:
• averaging the media file into N parts with a certain length, subjecting each of the N parts to hash operation to obtain a Block Content Identity (BCID) for each part, and then subjecting all BCIDs to hash algorithm to obtain a Global Content Identity (GCID) which acts as the unique identification corresponding to the media file.

A storage device that stores program code for playing streaming media, wherein the program code is executable by a computing device to implement:

• a determining module, adapted to obtain information of a media file, which comprises an identification of the media file and a URL of the media file, and to determine at least two storages storing the media file by searching a network for the at least two storages according to a preset first correspondence relationship between the identification of the media file and information of the storages;
• a testing module, adapted to test connection speeds of the determined at least two storages;
• a processing module, adapted to:
• determine a storage of the at least two storages having a connection speed larger than a first threshold;
• obtain media streaming data corresponding to the media file from the storage;
• a playing module, adapted to play the obtained media streaming data;
• and
• an adjusting module, adapted to adjust the media streaming data corresponding to the obtained media file;
• wherein establishing the first correspondence relationship between the identification of the media file and the information of the storages comprises:
• allocating a unique identification to the media file;
• obtaining information of the storages storing the media file;
• and
• forming the first correspondence relationship between the identification of the media file and the information of the storages;
• wherein the allocating a unique identification comprises:
• averaging the media file into N parts with a certain length, subjecting each of the N parts to hash operation to obtain a Block Content Identity (BCID) for each part, and then subjecting all BCIDs to hash algorithm to obtain a Global Content Identity (GCID) which acts as the unique identification corresponding to the media file.
