当存在全参考时的客观感知多媒体视频质量测量 |
根据ITU-T J.148建议书的定义,多媒体一词指信息通信中使用的音频、视频、文本、图表、传真和电话等多种形式媒体的组合。针对多媒体客观评估方法,建议采用三步骤的方法。前两步将确定适合用于单独衡量视频和音频的感知质量工具。第三步讲确定音视频媒体的客观评估方法。本建议书包含了第一步 – 仅用于多媒体应用的视频。ITU-T J.247建议书提供了当可以获得部分参考信号时,选择适当客观感知视频质量衡量方法的导则。以下为可适用本建议书的示例应用:1) 互联网多媒体流2) 有线或其他网络中的视频电话和视频会议3) 有线网络中LCD显示器上观看的逐行视频电视流,包括采用互联网协议在互联网上传输的那些逐行视频电视流。(VGA是验证测试中最高的清晰度)4) 电信网的移动视频流5) 一些格式的IPTV视频有效载荷(VGA是该验证测试中最高的清晰度)。 |
