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.

Claims

1. A method of managing media clips over a data network, the method comprising:

displaying at least one user interface element on a display;

receiving a search input via an input device, wherein the search input identifies at least one metadata item;

transmitting a clip request to a metadata database based on the at least one metadata item, wherein the metadata database comprises metadata records associated with a plurality of timecoded references;

receiving at least one media clip identifier in response to the clip request;

requesting at least one media clip from a storage server based on the at least one media clip identifier;

receiving the at least one media clip from the storage server;

receiving a transformation input via the input device, wherein the transformation input identifies at least one transformation to apply to the at least one media clip;

applying the at least one transformation to the at least one media clip;

generating a first additional metadata item relating to the at least one media clip identifier and a second additional metadata item relating to the at least one transformation; and

transmitting the first additional metadata item and the second additional metadata item to the metadata database to update a metadata record corresponding to the at least one metadata item.

2. The method of claim 1, wherein each media frame within the corresponding at least one media clip comprises a unique identifier.

3. The method of claim 1, further comprising transmitting the at least one media clip to an output node.

4. The method of claim 1, further comprising:

receiving a request for at least one proxy media clip from a control station;

retrieving at least one media clip that corresponds to the at least one proxy media clip in response to the request;

transcoding the at least one media clip to generate the at least one proxy media clip; and

transmitting the at least one proxy media clip to an output node identified in the request.

5. The method of claim 1, further comprising displaying the at least one media clip.

6. The method of claim 1, wherein the at least one media clip comprises at least two media clips, the method further comprising:

selecting two or more media clips, wherein each of the two or more media clips originate from a source media stream, wherein each of the two or more media clips have an associated start and stop point within the source media stream; and

arranging the two or more media clips in a sequence.

7. The method of claim 6, further comprising recording the sequence as a single media clip.

8. The method of claim 6, further comprising recording the sequence as metadata indicating the source media stream for each of the two or more media clips in the sequence, along with the start and stop point within the source media stream for each of the two or more media clips in the sequence.

9. A system for managing media clips, the system comprising:

a data network;

a metadata database comprising a plurality of metadata records associated with a plurality of timecode references;

a storage server; and

a processor coupled to a memory, the processor being coupled to the metadata database and the storage server via the data network, and being configured to;

display at least one user interface element on a display;

receive a search input via an input device, wherein the search input identifies at least one metadata item;

transmit a clip request to a metadata database based on the at least one metadata item;

receive at least one media clip identifier in response to the clip request;

request at least one media clip from a storage server based on the at least one media clip identifier;

receive the at least one media clip from the storage server;

receive a transformation input via the input device, wherein the transformation input identifies at least one transformation to apply to the at least one media clip;

apply the at least one transformation to the at least one media clip;

generate a first additional metadata item relating to the at least one media clip identifier and a second additional metadata item relating to the at least one transformation; and

transmit the first additional metadata item and the second additional metadata item to the metadata database to update a metadata record corresponding to the at least one metadata item.

10. The system of claim 9, wherein the storage server is further configured to generate a unique identifier for each media frame within the corresponding at least one media clip.

11. The system of claim 9, wherein the storage server is further configured to transmit the at least one media clip to an output node.

12. The system of claim 9, wherein the storage server is further configured to:

receive a request for at least one proxy media clip from a control station;

retrieve at least one media clip that corresponds to the at least one proxy media clip in response to the request;

transcode the at least one media clip to generate the at least one proxy media clip; and

transmit the at least one proxy media clip to an output node identified in the request.

13. The system of claim 9, wherein the control station is further configured to display the at least one media clip.

14. The system of claim 9, wherein the control station is further configured to:

select two or more media clips, wherein each of the two or more media clips originate from a source media stream, wherein each of the two or more media clips have an associated start and stop point within the source media stream; and

arrange the two or more media clips in a sequence.

15. The system of claim 9, wherein the control station is further configured to record the sequence as a single media clip.

16. The system of claim 9, wherein the control station is further configured to record the sequence as metadata indicating the source media stream for each of the two or more media clips in the sequence, along with the start and stop point within the source media stream for each of the two or more media clips in the sequence.
