Abstract

In this paper, we designed an embedded audio video bridging (AVB) platform based on IEEE 802.1BA for real-time multimedia transmission in smart-car, smart-home, smart-theater, and then evaluated a performance of the implemented platform by analysis of IEEE 802.1AS (time synchronization protocol) and IEEE 802.1Qat (stream reservation protocol). Especially, the AVB Layer-2 protocol of MRP(Multiple Registration Protocol), MMAP(Multicast Address Acquisition Protocol), IEEE 1722, 1722.1 etc. was and implemented by linux based operating system. It is shown by interoperability tests with commercial products that the implemented platform transmits real-time multichannel AV data over AVB networks for Multichannel Multimedia Transmission.

본 논문에서는 고품질 멀티미디어 데이터를 IEEE 802.1 Audio Video Bridging 기반의 네트워크를 통해 스마트 자동차와 스마트 홈 및 스마트 공연장에서 실시간으로 송수신할 수 있는 임베디드 플랫폼을 설계를 통해 정밀한 시간 동기화 표준인 IEEE 802.1AS와 QoS 보장을 위한 자원할당 표준인 IEEE 802.1Qat 프로토콜 분석을 통해 성능을 검증한다. 이를 위해 MRP(Multiple Registration Protocol), MMAP(Multicast Address Acquisition Protocol), IEEE 1722, 1722.1 등 AVB의 핵심 Layer-2 프로토콜을 리눅스 운영체제를 기반으로 구현한다. 아울러 상용 AVB 엔드포인트와 연동 실험을 통해 상호 호환성 및 멀티미디어 스트림의 실시간 송수신이 가능함을 보인다.
