Synchronizing media content tag data

1. A method comprising:

receiving first metadata associated with a first version of a media content item, wherein the first metadata includes a first plurality of hash value data sequences indicating a plurality of time-based positions in the first version of the media content item;

receiving second metadata associated with a second version of the media content item, wherein the second metadata includes a second plurality of hash value data sequences indicating a plurality of time-based positions in the second version of the media content item;

mapping the first plurality of hash value data sequences to corresponding hash value data sequences of the second plurality of hash value data sequences to create stream timing metadata;

determining segment boundaries of segments within the first version of the media content item and segments within the second version of the media content item;

mapping the segment boundaries of segments within the first version of the media content to corresponding segments within the second version of the media content to create segment metadata; and

embedding the stream timing metadata and the segment metadata into the second version of the media content item.

2. The method of claim 1 , wherein the first version of the media content item comprises a reference version of the media content item stored at a host media device.

3. The method of claim 1 , wherein the second version of the media content item comprises transcoded cloud-storage version of the media content item.

4. The method of claim 3 , wherein the second version of the media content item comprises a sequence of portions of the media content item transcoded for HTTP Live Streaming (HLS) protocol.

5. The method of claim 1 , wherein the stream timing metadata includes a hash value of a segment of the media content item and a start time value in seconds of the segment of the media content item.

6. The method of claim 1 , further comprising:

receiving an input, wherein the input corresponds to a request to play the media content item beginning at a specified point in time;

determining, based on the stream timing metadata, a frame in the second version of the media content item corresponding to the specified point in time; and

causing to be displayed the second version of the media content item beginning with the specified point in time.

7. The method of claim 1 , wherein mapping the segment boundaries comprises identifying segment transitions within the media content item.

8. The method of claim 7 , wherein the segment transitions include at least one of a change in a style of closed caption text associated with the media content item, a change in an audio level of the media content item, an instance of scene blanking, and a display of a known advertisement.

9. A system comprising:

control circuitry configured to:

receive first metadata associated with a first version of a media content item, wherein the first metadata includes a first plurality of hash value data sequences indicating a plurality of time-based positions in the first version of the media content item;

receive second metadata associated with a second version of the media content item, wherein the second metadata includes a second plurality of hash value data sequences indicating a plurality of time-based positions in the second version of the media content item;

map the first plurality of hash value data sequences to corresponding hash value data sequences of the second plurality of hash value data sequences to create stream timing metadata;

determine segment boundaries of segments within the first version of the media content item and segments within the second version of the media content item;

map the segment boundaries of segments within the first version of the media content to corresponding segments within the second version of the media content to create segment metadata; and

embed the stream timing metadata and the segment metadata into the second version of the media content item.

10. The system of claim 9 , wherein the first version of the media content item comprises a reference version of the media content item stored at a host media device.

11. The system of claim 9 , wherein the second version of the media content item comprises transcoded cloud-storage version of the media content item.

12. The system of claim 11 , wherein the second version of the media content item comprises a sequence of portions of the media content item transcoded for HTTP Live Streaming (HLS) protocol.

13. The system of claim 9 , wherein the stream timing metadata includes a hash value of a segment of the media content item and a start time value in seconds of the segment of the media content item.

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

receive an input, wherein the input corresponds to a request to play the media content item beginning at a specified point in time;

determine, based on the stream timing metadata, a frame in the second version of the media content item corresponding to the specified point in time; and

cause to be displayed the second version of the media content item beginning with the specified point in time.

15. The system of claim 9 , wherein mapping the segment boundaries comprises identifying segment transitions within the media content item.

16. The system of claim 15 , wherein the segment transitions include at least one of: a change in a style of closed caption text associated with the media content item, a change in an audio level of the media content item, an instance of scene blanking, and a display of a known advertisement.
