Core value “국제표준기술 및 국제단체기술들이 극복하지 못한 IPTV 서비스의 전 세계적인 문제점”

실시간 방송과 주문형 방송 등의 선택 시 5초 ~ 15초간의 버퍼링 대기시간

고비용이 투자되는 멀티캐스팅이 가능한 Premium Network 구축을 통

하여 실시간 방송의 즉시시청은 달성하였으나, VOD 는 15초가 소요됨.

음성/영상/자막 동기화의 배속재생 불가로 서비스의 만족을 달성하지 못함.

언어학습 등 콘텐츠의 활용성 증대를 위하여 필요하지만, 고비용이 투

자된 Premium Network 에서도 VTR 수준의 건너뛰기 탐색 수준임.

음성/영상/자막 동기화의 실시간 탐색 불가로 서비스의 만족에 미달함.

DVD 플레이어의 죠그-셔틀 수준의 실시간 탐색이 요구되나, 고비용이 투

자된 Premium Network 에서도 VTR 수준의 건너뛰기 탐색 수준임.

항상 TV를 켜놓는 시청자의 잘못된 습관으로 동시접속수가 증가한다.

접속자의 증가에 따른 스트리밍 서버의 증설이 불가피하여 TCO 증가.

Premium Network 및 Platform 구축 등에 TCO/CAPEX/OPEX 의 증가.

소유비용, 운영비, 자본적 지출 등은 증가하지만 Internet Service 가 불가능하여 국지적이고 자가망에 국한된 서비스로 매출과 수익성에 한계점.

Internet Protocol-RTP “Real-time Transport Protocol (RTP)”

RTP 란 : Real-time Transport Protocol 로써, 실시간으로 대용량 멀티미디어의 전송을 위한 통신 규약으로 네트워크 상에서 스트리밍 데이터를 전송하는 방법에 대한 국제표준. 1995년11월 IESG(Internet Engineering Steering Group) 표준제정 : IETF 코덱별 표준규격 발표. 등장배경

-. UDP의 상위 프로토콜로써 조금은 비 신뢰적이지만 대용량 전송을 가능케 할 목적으로 개발됨. 특 징 :

-. 단방향 대용량 데이터 전송과 빠른 데이터 전송으로 버퍼링 시간을 최소화하여 QoS/QoE 달성. . RTP 자체로는 품질과 신뢰성의 미 보장, RTSP/RTCP 조합으로 품질과 신뢰성을 향상 시킴. . 시간 정보와 정보 매체의 동기화 기능 제공으로 고품질의 멀티미디어 스트리밍 서비스 달성. -. IP 패킷에 캡슐화될 수 없어 어플리케이션 계층에서 UDP 데이터그램에 캡슐화되어 패킷전송. . 다른 Layer3, Layer4 계층과 같이 사용하며, 하위 프로토콜에 의존성이 적으며, 짝수 포트 사용.

“Real Time Streaming Protocol (RTSP)”

RTSP 란 : Real Time Streaming Protocol 로써, 실시간으로 미디어의 전송을 행하는 어플리케이션 계층의 프로토콜로써 멀티미디어를 송.수신하기 위한 통신규약으로 네트워크 상에서 스 트리밍 데이터의 흐름제어와 VCR 제어를 위한 방법에 대한 국제표준 1998년4월 IETF 표준제정 : Real Networks, Netscape communication, Columbia University 개발.

RTSP Ver. 1.0(RFC2326), RTSP Ver. 2.0 등장배경

-. 안전하며 완전한 데이터의 전송을 위하여 TCP가 적당하나 멀티미디어 전송에 느린속도 문제.

-. UDP를 대안으로 삼을 수 있으나, 패킷 손실 및 순서위반 등으로 인하여 매체의 품질에 영향.

-. 실시간 응용 어플리케이션을 위한 TCP와 UDP를 대체할 수 있는 실시간 전용 프로토콜 필요. 특 징 :

-. 양방향 실시간 흐름제어와 조금은 비 신뢰적인 RTP 전송의 데이터 신뢰성을 향상 시키며, 네트 워크 오버헤드 및 지터(도착 지연 시간) 수 억제로 QoS/QoE 달성

. 패킷 손실을 실시간으로 탐지하여 손실률이 크면 전송률을 낮추고 적으면 전송률을 높임 . 클라이언트 버퍼가 Over flow 되면 전송률을 낮추고 Underflow 되면 전송률을 높임

-. 인터넷 상에서 VCR처럼 Play, Rewind, Fast forward, Pause, Result 구현으로 QoS 달성

RFC 2326 Real Time Streaming Protocol 1.0 up to RTSP 2.0 4567 Key management extensions for SDP and RTSP 6064 SDP & RTSP Extensions defined for 3GPP packet switched streaming service & multimedia BCAST

“Real Time Control Protocol (RTCP)”

RTCP 란 : Real Time Control Protocol 로써, RTP 보다는 상위 계층의 UDP Layer 기반의 비 연결 프로토콜로써 클라이언트와 서버간의 멀티미디어 스트리밍에 대한 실시간 제어를 위한 방법에 대한 국제표준.

1997년 IETF 표준제정 : RFC 4571

등장배경 -. 단방향성의 RTP의 기능상의 문제점을 보완하기 위한 RTP 부속 프로토콜의 필요성.

특 징 : -. 서버/클라이언트간 QoS 정보를 교환/평가하여 끊김 없는 고품질 미디어 서비스로 QoS/QoE달성.

. 품질의 감시 . 데이터운반 지시/초기화

. 체증의 제어 . Presentation Control

. 매체간 동기화 . Stream Commend/Control

. 발신지의 식별 . 패킷송신률을 계산/참여자

. 세션크기 추정 ID의 최소한 제어정보 나름

-. RTCP 패킷의 트래픽 크기를 전체의 5% 이내로 제한하고 접속자의 수에 따라 전송의 빈도를 달 리 함으로써 스트리밍 제어를 위한 네트워크의 트래픽 증대를 억제하여 효율적 네트워크 사용. -. RTCP는 RTP 다음의 홀수 UDP 포트를 사용하며, RTCP 제어에 대한 요청은 TCP를 사용한다.

SDP 란 : Session Description Protocol 로써, 인터넷에서 멀티미디어 세션에 참여하기 위한 사용자 가 필요로 하는 정보를 제공하는 실시간 멀티미디어 세션의 정의에 대한 국제표준.

RFC2327(4566개정) 표준제정 : MMUSIC(Multiparty Multimedia Session Control) Working Group

등장배경
