IP technology is suitable for broadcast stations aimed at diversification of broadcasting services such as 4K/8K UHDTV due to its ease of multiplexing and ability to perform bidirectional communication, along with the decrease in cost per bit. Therefore, live program production systems using IP technology are considered an effective means for implementing broadcasting systems more efficiently and flexibly. Remote production is attracting attention as a new style of live program production using IP. In remote production, broadcast stations and venues are connected by IP network, and programs are remotely produced from the broadcast station side. To enable remote production, it is necessary for both the venue and the broadcast station to share, in real-time, high-quality video taken at the venue. It is also required to bidirectionally communicate signals other than video/audio that are necessary for program production, such as control and communication line signals. To realize 8K remote production, we have developed a lightweight compressed 8K over IP transmission device. In this work, we describe its functions and report experimental results on multi-channel audio remote production with 8K video and real-time 8K camera control on a 1000-km IP network.","PeriodicalId":156441,"journal":{"name":"2018 Principles, Systems and Applications of IP Telecommunications (IPTComm)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123773106","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}

One of the impairment factors that IP networks exhibit which affects the quality of voice services is packet loss. Different types of networks will have different packet loss characteristics, with most being susceptible to bursty loss, which can be significantly detrimental to voice quality. As part of the evolution of codec technologies, Enhanced Voice Services (EVS) has been introduced by 3GPP in order to provide higher speech and audio qualities at lower bitrates and higher resilience to packet loss compared with previous communication codecs. In this paper, a method has been developed for characterising and comparing the performance of codecs under different bursty packet loss characteristics. It has been used to compare the performance of EVS with AMR-WB and G.722. EVS has been tested with and without its partial redundancy mode, known as Channel-Aware (CA) mode. All codecs have been tested using a range of different packet loss profiles (PLPs) with loss rate values reaching 20% and mean burst length values going up to 10 packets. It was found that EVS with and without CA performs better than AMR-WB and G.722 for almost all the tested PLPs.","PeriodicalId":156441,"journal":{"name":"2018 Principles, Systems and Applications of IP Telecommunications (IPTComm)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121643298","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}
