Excessive playout buffering at the receiver is prohibitive and significantly delayed packets have to be discarded and considered as late loss. We propose to improve the tradeoff among delay, late loss rate, and speech quality using multi-stream transmission of real-time voice over the Internet, where multiple redundant descriptions of the voice stream are sent over independent network paths. Scheduling the playout of the received voice packets is based on a novel multi-stream adaptive playout scheduling technique that uses a Lagrangian cost function to trade delay versus loss. Experiments over the Internet suggest largely uncorrelated packet erasure and delay jitter characteristics for different network paths which leads to a noticeable path diversity gain. We observe significant reductions in mean end-to-end latency and loss rates as well as improved speech quality when compared to FEC protected single-path transmission at the same data rate. In addition to our Internet measurements, we analyze the performance of the proposed multi-path voice communication scheme using the ns network simulator for different network topologies, including shared network links.","PeriodicalId":416848,"journal":{"name":"MULTIMEDIA '01","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125236524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A recent study indicates that less than 1% of documents on the web include streaming media links [AshourOl 1. Text continues to be the primary information source today with media being peripheral, if at all. In parallel, the resources for locating relevant information contained in streaming media, such as search engines, web directories and portals are not as well developed as those for text. What is the problem here? Is it the lack of resources for media that are an impediment to making media mainstream? Or is it the lack of compelling reasons to use media the reason for the lack of resources? The indexing challenges offered by the unstructured, spatio-temporal nature of media together with the lack of universal media standards largely accounts for this [Chang98, Gupta97, Jones96, Wactlar99, Zhang961. Further, media offers additional complexity due to content rights protection issues that prevent free sharing of media. This panel brings together experts from the today’s leading streaming media formats together with representatives of o p e n standards for media. They are Synchronized Multimedia Integration Language (SMIL), MPEG-4, Real Media, Windows Media and QuickTime.

Jang, Hong-Ru Lee","doi":"10.1145/500141.500201","DOIUrl":"https://doi.org/10.1145/500141.500201","url":null,"abstract":"This paper presents an implementation of a content-based music retrieval system that can take a user's acoustic input (8-second clip of singing or humming) via a microphone and then retrieve the intended song from a database containing over 3000 candidate songs. The system, known as Super MBox, demonstrates the feasibility of real-time music retrieval with a high success rate. Super MBox first takes the user's acoustic input from a microphone and converts it into a pitch vector. Then a hierarchical filtering method (HFM) is used to first filter out 80% unlikely candidates and then compare the query input with the remaining 20% candidates in a detailed manner. The output of Super MBox is a ranked song list according to the computed similarity scores. A brief mathematical analysis of the two-step HFM is given in the paper to explain how to derive the optimum parameters of the comparison engine. The proposed HFM and its analysis framework can be directly applied to other multimedia information retrieval systems. We have tested Super MBox extensively and found the top-20 success rate is over 85%, based on a dataset of about singing/humming 2000 clips from people with mediocre singing skills. Our studies demonstrate the feasibility of using Super MBox as a prototype for music search engines over the Internet and/or query engines in digital music libraries.","PeriodicalId":416848,"journal":{"name":"MULTIMEDIA '01","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129676074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
