Abstract

The embodiment of the invention discloses a stream media version aligning method and stream media version aligning equipment, wherein the method comprises the following realization steps of: obtaining a first stream medium and a second stream medium, wherein the first stream medium and the second stream medium are different versions of the same stream medium; carrying out cross-correlation calculation on the first stream medium and the second stream medium to obtain a cross-correlation maximum position, and then, determining the time migration of the cross-correlation maximum position of the first stream medium and the second stream medium; and aligning the first stream medium and the second stream medium according to the time migration. The cross-correlation calculation is used for determining the cross-correlation maximum position; then, the time migration is determined according to the cross-correlation maximum position; and the time migration between the stream media of different versions can be accurately determined, so that the alignment of stream medium versions is realized. Compared with a scheme adopting an energy method, the scheme provided by the invention has the advantages that the limitation is little, and the wide application can be realized, so that the success rate of the stream medium version alignment is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a streaming media version alignment method and equipment. Background technique [0002] Streaming media is a data stream played in time order, for example: audio songs, video movies, etc. Taking songs as an example, on the Internet, due to the needs of transmission and production, the same song may be rewritten into many different versions, resulting in different singing positions of the song, but in fact the lyrics and the main melody of the song are both identical. In order for some resources (eg lyrics, video) to be reused when presented to the user, it is necessary to find out the starting point where different versions of the same song begin to sing, or to find the time delay between different versions of the song. [0003] In order to realize automatic singing position alignment, there are many ways. for example: [0004] 1. On the premise that the lyrics of the two v...
