Method, apparatus, and system for processing media data

A media server, comprising:

• a play request receiving unit, configured to receive a play request which carries information of media content to be played;
• and
• a data obtaining unit, configured to:
• obtain, according to the information of the media content to be played, information of a source server and media data from a locally stored media data segment;
• determine, according to play time of the locally stored media data segment, start time and/or end time of a media data segment to be obtained from the source server;
• and obtain, according to at least one of the determined start time and end time of the media data segment, the media data segment from the source server.

A media data processing method, comprising:

• receiving a media data obtaining request which carries feature data;
• determining a play unit to be sent according to the media data obtaining request;
• checking whether feature data of the play unit to be sent matches the feature data in the request;
• and
• sending data from a play unit next to the play unit whose feature data matches that in the media data obtaining request if the feature data of the play unit to be sent matches the feature data in the media data obtaining request, wherein an all-open interval may be used to indicate a play range.

A source server, comprising:

• a request receiving unit, configured to receive a media data obtaining request which carries feature data;
• a determining unit, configured to determine a play unit to be sent according to the media data obtaining request;
• a checking unit, configured to check whether feature data of the play unit to be sent matches the feature data in the media data obtaining request;
• and
• a sending unit, configured to send media data from a play unit next to the play unit whose feature data matches that in the media data obtaining request.

A media data processing system, comprising a media server and a source server, wherein:

• the media server comprises:
• a play request receiving unit, configured to receive a play request which carries information of media content to be played;
• and
• a data obtaining unit, configured to:
• obtain, according to the information of the media content to be played, information of the related source server and media data from a related locally stored media data segment;
• determine, according to play time of the locally stored media data segment, start time and/or end time of a media data segment to be obtained from the source server;
• and obtain, according to the determined start time and/or end time of the media data segment, the media data segment from the source server;
• the source server comprises:
• a request receiving unit, configured to receive a media data obtaining request which carries feature data;
• a determining unit, configured to determine a play unit to be sent according to the media data obtaining request;
• a checking unit, configured to check whether feature data of the play unit to be sent matches the feature data in the media data obtaining request;
• and
• a sending unit, configured to send media data from a play unit next to the play unit whose feature data matches that in the request.
