Abstract

In this paper, we present a design and implementation of a personalized broadcasting system using TV-Anytime metadata for providing personalized services. The TV-Anytime specifies metadata schema, metadata coding and delivery, and provides service models to provide personalized broadcasting content services at anytime when users want to consume using metadata, which includes ECG (Electronic Content Guide) and content descriptive information in a PDR (Personal Digital Recorder)-centric environment. The proposed personalized broadcasting system consists of a server that provides metadata binary-coding, encapsulation and multiplexing, and a client terminal that takes charge of de-multiplexing, metadata decoding, and metadata processing for personalized content accessing and consumption. This paper presents the details of the design of each functional module, and the evaluation results with a set of service scenarios in an end-to-end broadcasting test-bed.

본 논문은 TV-Anytime 메타데이터를 이용하여 맞춤형 방송 서비스를 제공하기 위한 맞춤형 방송 전송 시스템의 설계 및 구현에 관한 것이다. TV-Anytime은 저장장치를 갖는 수신기 환경에서 ECG(Electronic Content Guide) 및 콘텐츠 기술(description) 메타데이더를 이용하여 시청자가 원하는 시간에 시청자의 취향에 따른 개인화된 방송 콘텐츠 서비스를 제공하기 위한 메타데이터 스키마 및 메타데이터 부호화/전송 등의 제반 표준 및 서비스 모델을 제시하고 있다. 본 논문에서는 제시하는 TV-Anytime 기반의 맞춤형 방송 전송 시스템은 전송 서버단에서의 메타데이터 이진 부호화 및 MPEG-2 TS(Transport Stream) 다중화, 그리고 단말에서의 역다중화. 복호화 및 메타데이터 기반의 맞춤형 콘텐츠 소비 기능 등을 포함한다. 본 논문에서는 제시하는 전송 시스템의 각 기능 모듈들의 설계 및 구현의 상세 기술과 맞춤형 콘텐츠 서비스 시나리오를 이용한 서버-단말간의 검증 결과를 기술한다.
