<p>巴西已确定采用MPEG-H音频系统传输沉浸式和互动式音频，极大地增强了现有ISDB-Tb地面数字电视系统。数码视讯快速响应，并在其最新的10k118广播电视编码器中加入MPEG-H音频的支持。</p>
<p><span>数码视讯</span><span>10k118</span><span>是一款高性能且易于使用的编码器，适用于有线、卫星、</span><span>IPTV</span><span>和地面数字电视等应用场景。在</span><span>Fraunhofer IIS</span><span>和数码视讯双方技术团队的紧密配合下，</span><span>数码视讯</span><span>10k118</span><span>成功集成了</span><span>MPEG-H</span><span>音频，且能够输出满足巴西最新</span><span>ABNT</span><span>广播电视标准要求的</span><span>ISDB-Tb</span><span>码流。这使得电视台可以在现有的</span><span>SBTVD/ISDB-Tb</span><span>系统上同时播出</span><span>AAC</span><span>音频和具备沉浸声及互动式功能的</span><span>MPEG-H</span><span>音频内容。</span></p>
<p><span>数码视讯的实时广播电视编码器现已支持所有主要的视频格式，并通过</span><span>ISDB-T</span><span>、</span><span>DVB-T2</span><span>和</span><span>DVB-C</span><span>在各种高清和超高清广播服务中传输</span><span>MPEG-H</span><span>音频。此外，数码视讯</span><span>10k118</span><span>的集成方案也将为中国超高清视频的产业发展贡献力量。</span></p>
<p><span>数码视讯高级产品经理郭佳颖表示：</span><span>“Fraunhofer IIS</span><span>是我们音频解决方案的长期合作伙伴，我们非常高兴能够使用</span><span>MPEG-H</span><span>音频。数码视讯的产品遍布全球</span><span>110</span><span>多个国家和地区，服务于全球</span><span>10</span><span>亿人口，我们相信</span><span>MPEG-H</span><span>音频将会为更多家庭带来创新音频体验。”</span></p>
<p><span>MPEG-H</span><span>音频系统在设计之初便能够同时支持</span><span>SDI</span><span>和</span><span><span> </span>IP</span><span>传输。其独特的方案使</span><span>MPEG-H</span><span>元数据能够通过</span><span>SDI</span><span>上的</span><span>PCM</span><span>通道进行传输，并始终保持与视频帧率同步。</span><span>MPEG-H</span><span>制作与监听单元可用于个性化功能的直播制作，并实时向数码视讯编码器提供</span><span>MPEG-H</span><span>元数据。</span></p>
<p><span>Fraunhofer IIS</span><span>中国区负责人</span><span>Toni Fiedler</span><span>表示</span><span>: “</span><span>目前所有主流广播电视标准均采用了</span><span>MPEG-H</span><span>音频，这将极大地提升广播电视服务水平及并为消费者带来丰富音频体验。数码视讯对</span><span>MPEG-H</span><span>音频的支持是</span><span>Fraunhofer</span><span>的又一个里程碑，符合</span><span><span> </span>Fraunhofer</span><span>一直以来对市场的承诺，即为全球尤其是巴西、中国以及欧洲市场提供高质量的领先音频技术。”</span></p>
