Dalam kertas kerja ini, kami mencadangkan kaedah pemampatan pengepala RTP/UDP/IP, Pemampatan Rujukan Berbilang (MRC), yang direka bentuk untuk komunikasi multimedia mudah alih. MRC ialah kaedah mampatan yang mengira perbezaan daripada berbilang pengepala rujukan yang telah dihantar dan memasukkannya ke dalam pengepala termampat. Penerima boleh menyahmampat pengepala termampat selagi sekurang-kurangnya satu daripada pengepala rujukan diterima dengan betul dan dinyahmampat. MRC meningkatkan keteguhan terhadap kehilangan paket berbanding dengan CRTP yang ditakrifkan dalam IETF RFC2508, dan mengenakan kurang overhed dan beban pengiraan daripada mampatan pengepala teguh (ROHC) yang ditakrifkan dalam RFC3095. Kami juga melaksanakan MRC dan algoritma pemampatan pengepala lain ke dalam katil ujian mudah alih kami, dan menjalankan eksperimen penstriman multimedia di atas katil ujian. Keputusan eksperimen menunjukkan bahawa MRC menawarkan tahap kadar kehilangan paket yang sama seperti RTP Lama untuk kedua-dua strim audio dan video, dan menyediakan kualiti media yang lebih baik daripada RTP dan CRTP Legacy pada pautan radio yang terdedah kepada ralat. Mampatan tajuk yang teguh terhadap kehilangan paket dijangka sebagai teknologi utama untuk perkhidmatan penstriman VoIP dan multimedia melalui 3G dan rangkaian mudah alih masa hadapan.

Abstract: In this paper, we propose an RTP/UDP/IP header compression method, Multiple-Reference Compression (MRC), which is designed for mobile multimedia communications. MRC is a compression method that calculates differences from the multiple reference headers that have already been sent and inserts them into a compressed header. The receiver can decompress the compressed header as long as at least one of the reference headers is correctly received and decompressed. MRC improves robustness against packet losses compared with CRTP defined in IETF RFC2508, and imposes less overheads and computational burden than robust header compression (ROHC) defined in RFC3095. We also implemented MRC and other header compression algorithms into our mobile testbed, and conducted multimedia streaming experiments over the testbed. The results of the experiments show that MRC offers the same level of packet loss rate as Legacy RTP for both audio and video streams, and provides better media quality than Legacy RTP and CRTP on error-prone radio links. Header compression robust against packet losses is expected as a key technology for VoIP and multimedia streaming services over 3G and future mobile networks.
