- 초록
- Multimedia service can be categorized as conversational, streaming, and download services, which differ in temporal and semantic quality requirements. Performance of SVC (Scalable video coding) is analyzed in the three dimensional (spatio-temporal) frequency domain. Based on the analysis, SVC scheme can be modified to satisfy various requirements as being compliant to the international standards. Decoding without enhancement layer data results in drift phenomenon. Several drift-free techniques are analyzed.
