Abstract: A data deduplication method includes: acquiring a live streaming data stream to be processed, wherein the data stream includes at least one audio/video packet; and executing following operations on one audio/video packet, each audio/video packet carrying an identifier, and the identifier being determined according to the order of the audio/video packet in the live streaming data stream; determining, according to the identifier of the audio/video packet, whether the audio/video packet is a repeatedly acquired audio/video packet, and if so, discarding the audio/video packet. Accordingly, it is ensured that no unduplicated data is sent to a user, and the problem that in a live streaming process, due to the fact that an intermediate link is reconnected, a user acquired part of duplicated data, and the audio/video rollback phenomenon caused by the duplicated data being played is solved.

Abstract: A data distribution system includes: an edge stream-pushing server configured to receive streaming media data packets sent by a stream pusher, serialize the streaming media data packets, and forward the serialized streaming media data packets to a plurality of central servers; a central server configured to cache the serialized streaming media data packets, if a serialized back-to-source request from the edge stream-pulling server is received, determine, a start position of to-be-transmitted streaming media data packets according to the serialized back-to-source request, and send the cached streaming media data packets to the edge stream-pulling server according to the start position; and an edge stream-pulling server configured to deserialize received streaming media data packets to restore the received streaming media data packets, and send the restored streaming media data packets to a user terminal.

Abstract: The present disclosure discloses a method and an apparatus for adjusting a timestamp of a live streaming video, relating to the field of video processing technology. The method includes: acquiring a target audio/video frame of the live streaming video and determining the timestamp corresponding to the target audio/video frame; based on the timestamp corresponding to an audio/video frame preceding the target audio/video frame, deciding whether the timestamp corresponding to the target audio/video frame is abnormal; and if abnormal, adjusting the timestamp corresponding to the target audio/video frame based on the timestamp corresponding to the preceding audio/video frame. The present disclosure ensures that the timestamps of the entire live data stream of the live streaming video are continuously stable and improves the playing stability of the live streaming video.
