Abstract
Methods and system for managing media clips over a data network. Media streams may be received over a data network and stored by a storage server. Metadata regarding the media streams may be generated and stored at a metadata server. A control station can retrieve media frames originating in the stored media streams from the storage server, based on metadata. Media frames from multiple media streams can be retrieved and displayed in synchronization, based on respective timecodes.
Claims20
A method of managing media clips over a data network, the method comprising:
- receiving a plurality of original media streams corresponding to a single event from a plurality of media sources, wherein each original media stream comprises a plurality of media frames;
- for each of the plurality of original media streams, determining a timecode for the corresponding original media stream by extracting one or more timecode packets embedded in one or more portions of the original media stream, the timecode comprising a plurality of timecode references corresponding respectively to the plurality of media frames, wherein each timecode reference is a timing reference associated with a point in time on a timebase, and wherein all timecode references associated with the original media stream are referenced to the timebase;
- determining whether timecode references for at least two original media streams received from at least two different media sources are referenced to a common timebase;
- for each of the plurality of original media streams having timecode references referenced to the common timebase, storing the original media stream at a storage server;
- if the timecode references for the at least two original media streams are not referenced to the common timebase, then for each original media stream that is not referenced to the common timebase:
- generating one or more new timecode packets comprising new timecode references referenced to the common timebase;
- generating a modified media stream by embedding, into the one or more portions of the media stream from which the timecode packets were extracted, the one or more new timecode packets comprising the corresponding new timecode references;
- and
- storing the modified media stream at a storage server;
- and
- for each stored media stream, generating at least one stored metadata record in a metadata database, each stored metadata record comprising a stored media stream identifier corresponding to the stored media stream, and one or more metadata tags, wherein each stored media stream is referenced to the common timebase.

A system for managing media clips, the system comprising:
- a data network;
- a plurality of media sources;
- a metadata server;
- a storage server coupled to the metadata server via the data network;
- and
- a controller,
- wherein
- the storage server is configured to:
- receive a plurality of original media streams corresponding to a single event from the plurality of media sources, wherein each original media stream comprises a plurality of media frames;
- and
- the controller is configured to:
- for each of the plurality of original media streams, determine a timecode for the corresponding original media stream by extracting one or more timecode packets embedded in one or more portions of the original media stream, the timecode comprising a plurality of timecode references corresponding respectively to the plurality of media frames, wherein each timecode reference is a timing reference associated with a point in time on a timebase, and wherein all timecode references associated with the original media stream are referenced to the timebase;
- determine whether timecode references for at least two original media streams received from at least two different media sources are referenced to a common timebase;
- for each of the plurality of original media streams having timecode references referenced to the common timebase, store the original media stream in the storage server;
- and
- if the timecode references for the at least two original media streams are not referenced to the common timebase, then for each of the plurality of original media streams that is not referenced to the common timebase:
- generate one or more new timecode packets comprising new timecode references referenced to the common timebase;
- and
- generate a modified media stream by embedding, into the one or more portions of the media stream from which the timecode packets were extracted, the one or more new timecode packets and comprising the corresponding new timecode references;
- and
- store the modified media stream in the storage server;
- and
- for each stored media stream, generating at least one stored metadata record in a metadata database, each stored metadata record comprising a stored media stream identifier corresponding to the stored media stream, and one or more metadata tags, wherein each stored media stream is referenced to the common timebase.
