Media stream fragment request

A system comprising:

• a client system operable to interact with a server system and to perform operations comprising:
• receiving, at the client system, an index of a media stream, the media stream being fragmented into multiple sequentially arranged fragments, each of the fragments having an associated identifier, the index comprising a list of sequentially arranged fragment identifiers corresponding to at least a portion of the multiple sequentially arranged fragments;
• requesting, from the server system, fragments of the media stream based on the received index;
• receiving, from the server system, at least a portion of the requested index based fragments of the media stream;
• identifying fragment identifiers that are potentially missing from the received index, the identifying comprising identifying a gap in the list of sequentially arranged fragment identifiers based, at least in part, on a determined naming convention that indicates the sequential arrangement of the fragment identifiers;
• requesting, from the server system, potentially missing fragments associated with the potentially missing fragment identifiers, the requesting of potentially missing fragments occurring in series until a predetermined number of requests fail to return a potentially missing fragment;
• receiving one or more of the potentially missing fragments associated with the potentially missing fragment identifiers;
• and
• processing the received index based fragments and the one or more received potentially missing fragments for display.

A computer storage medium encoded with a computer program, the program comprising instructions that when executed by data processing apparatus cause the data processing apparatus to perform operations comprising:

• receiving, at a client system, an index of a media stream, the media stream being fragmented into multiple sequentially arranged fragments, each of the fragments having an associated identifier, the index comprising a list of sequentially arranged fragment identifiers corresponding to at least a portion of the multiple sequentially arranged fragments;
• requesting, from a server system, fragments of the media stream based on the received index;
• receiving, from the server system, at least a portion of the requested index based fragments of the media stream;
• identifying fragment identifiers that are potentially missing from the received index, the identifying comprising identifying a gap in the list of sequentially arranged fragment identifiers based, at least in part, on a determined naming convention that indicates the sequential arrangement of the fragment identifiers;
• requesting, from the server system, potentially missing fragments associated with the potentially missing fragment identifiers, the requesting of potentially missing fragments occurring in series until a predetermined number of requests fail to return a potentially missing fragment;
• receiving one or more of the potentially missing fragments associated with the potentially missing fragment identifiers;
• and
• processing the received index based fragments and the one or more received potentially missing fragments for display.
