Abstract

The OTT service that provides multimedia video has spread over the Internet for terminals with a variety of resolutions. The terminals are in communication via a networks such as 3G, LTE, VDSL, ADSL. The service of the network has been increased for a variety of terminals giving rise to the need for a new way of encoding multimedia is increasing. SVC is an encoding technique optimized for OTT services. We proposed an efficient multimedia management system for the SVC encoded multimedia data. The I/O trace was generated using a zipf distribution, and were comparatively evaluated for performance with the existing system.

여러 종류의 해상도를 가지는 단말들에 대해 인터넷을 통해 멀티미디어 동영상을 제공하는 OTT 서비스가 확산되고 있다. 각 단말들은 3G, LTE, VDSL, ADSL등 네트워크 망을 이용한 통신을 하고 있다. 다양한 해상도의 단말들과 다양한 속도의 네트워크망의 이용자들에 맞춰서 새로운 멀티미디어의 압축방식의 필요성이 높아졌다. 스케일러블 부호화 방식은 시간적/공간적 계위성을 제공하기 위해서 멀티미디어 데이터를 저장할 때 계층적 B 화면 구조를 이용하고 있다. 이를 이용하여 계층적으로 부호화된 멀티미디어 데이터는 OTT 서비스에 최적화 되어있으며, 이를 효율적으로 관리하기 위한 파일 배치 기법과 MLP 인기도 관리 정책, WFF 버퍼 캐시 관리 정책을 제안한다. 본 논문에서는 zipf 분포를 이용한 접근 트레이스를 생성하고, 기존 시스템과 제안한 시스템의 성능을 비교 평가하였다.
