Systems and Methods for Using Seektables to Stream Media Items

A first client device, comprising:

• one or more processors;
• and
• memory storing one or more programs, which when executed by the one or more processors cause the client device to:
• receive, from a second client device, a request to stream a media item from a first position within the media item;
• obtain, from a server, a seektable that identifies a plurality of segments into which content corresponding to the media item is divided, wherein each segment of the plurality of segments includes multiple samples;
• consult the seektable to determine a segment of the media item to retrieve in response to the request, the segment including content at the first position;
• after consulting the seektable, retrieve, from the server, the segment of the media item;
• and
• play the content corresponding to the first position using the retrieved segment.

A non-transitory computer-readable storage medium storing one or more programs configured for execution by one or more processors of a first client device, the one or more programs comprising instructions for:

• receiving, from a second client device, a request to stream a media item from a first position within the media item;
• obtaining, from a server, a seektable that identifies a plurality of segments into which content corresponding to the media item is divided, wherein each segment of the plurality of segments includes multiple samples;
• consulting the seektable to determine a segment of the media item to retrieve in response to the request, the segment including content at the first position;
• after consulting the seektable, retrieving, from the server, the segment of the media item;
• and
• playing the content corresponding to the first position using the retrieved segment.
