Method and apparatus for converting the modality of multimedia contents to support the quality of service according to media resource

Abstract

The present invention relates to modality conversion for supporting Quality of Service (QoS) according to media resources, which includes the steps of receiving a modality conversion descriptor in which the characteristics of the modality conversion of the multimedia contents are described, receiving the multimedia contents, and converting the modality of the multimedia contents into a modality determined according to a media resource and the modality conversion descriptor. According to the present invention, a systematic approach to a design for an overlap content value model is provided so that the conversion boundaries between modalities can be quantitatively calculated. As a result, the correlation between various modalities can be established in a single model, and modality conversion supporting the optimal QoS can be performed.
