FIELD: physics; video technology. ^ SUBSTANCE: invention relates to devices for re-encoding video data for real time streaming, and particularly to re-encoding video data for real time streaming in a mobile broadcast application. Proposed is a device for using content information to encode multimedia data, which includes a content classification module, which is configured to classify content multimedia data and provide content classification data, and an encoder which is configured to encode multimedia data in a first data group and a second data group based on content classification, wherein the first data group contains a coefficient, and the second group of data contains a first differential refinement associated with the coefficient of the first group of data. ^ EFFECT: design of a transcoder which provides for highly efficient processing and compression of multimedia data, which uses information defined from the said multimedia, and is scalable and error-tolerant for use in several multimedia data applications. ^ 49 cl, 45 dwg |
