Abstract

One of the most promising services on the wireless network is multimedia data service. With recently emerged wireless communication technologies which conventionally were devoted to mobile phone services, pre-encoded contents as well as live video data can be transmitted via the same network. As there is enough room in the improvement of data transmission bandwidth in wireless network, video data service is likely to be more demanding. In this paper, real time MPEG-4 video encoder is described as apart of a whole system for live video services over wireless networks. As there are minimal assumptions on the underlying networks, presented system and service can be easily supported by different network system.

이동통신에서의 멀티미디어 데이터 서비스는 매우 중요한 응용으로 떠 오른지 오래이다. 예전에는 이동전화를 위한 음성서비스에 국한되었으나, 근래의 기술발전으로 동영상을 서비스하기에 충분할 정도로 대역폭이 넓어졌다. 기술경쟁이 치열하고, 발전속도가 빠른 만큼, 동영상서비스에 대한 요구는 점점 늘어갈 것으로 예상된다. 본 논문에서는 이동통신에서 라이브 동영상 서비스를 제공하기 실시간 MPEG-4 비디오 인코더와 이를 위한 통신망의 구성에 대하여 서술한다. 통신망의 구성에 대한 가정을 최소로 했기 때문에 새로운 형식의 이동통신 기술이 대두된다 하더라도 본 논문에서 기술하는 동영상 서비스 시스템은 쉽게 적용 가능하다.
