Abstract

Recently, many kinds of TV contents based on multimedia need transmission systems without the saved. In this study, we develop the streaming device and smart app to transmit and play without store for multimedia contents such a broadcasting, internet, VOD, video, and animation. To do this, we compare and analysis main CPU products, broadcasting tuners and interfaces for streaming sources, and memory products. We then design and implement the streaming device which supports 30fps@FHD H.264 decoding and streaming, and multimedia sources with more than three. We develop the software for these requirements. Thissystemis useful to support billing service for multimedia contents.

최근 다양한 멀티미디어를 기반으로 한 다종류 TV 콘텐츠를 서비스에 있어, 저장 없이 전송하는 시스템의 개발이 필요하다. 본 연구에서는 방송/인터넷/VOD/카메라 기반의 동영상/애니메이션 등 멀티미디어 콘텐츠를 저장 없이 스트리밍 전송하여 다중의 일반재생기기 및 스마트폰을 이용하여 재생할 수 있는 스트리밍 기기 및 스마트기기용 앱 개발 방안을 제안한다. 이를위해 메인 CPU 비교분석, 방송용 튜너 및 스트리밍 소스와의 인터페이스 비교분석 그리고 메모리를 기준으로 기존 상용제품들을 분석한다. 이를 기반으로 재생 및 동시 스트리밍 성능을 30fps@FHD H.264 디코딩 및 동시 스트리밍할 수 있으며, 3종 이상의 멀티미디어 소스를 지원할 수 있는 하드웨어를 설계 구현하였다. 또한 트랜스코딩 능력은 30fps@FHD를 만족할 수 있는 소프트웨어 모듈을 개발하였다. 제안한 시스템은 멀티미디어 콘텐츠 과금 서비스에 효과적으로 활용될 수 있다.
