标准摘要
[中文适用范围]: 本部分 IEC 61883 规定了在 IEEE 1394 高性能串行总线上传输 ITU-R BT.601 4:2:2 格式(包括该格式的兼容扩展)的未压缩或压缩视频数据的协议。数据封装格式与 IEC 61883-1 兼容,关联音频数据应按照 IEC 61883-6 格式化。 IEC 61883 不支持 MPEG-4、Windows Media Format (WMF) 和汽车导航应用等常见视频格式。为避免解码器负担,源设备应转换为 ITU-R BT.601 4:2:2 格式并使用通用编解码器。该规范支持消费电子、汽车导航和航空娱乐等应用场景。 为确保互操作性,规范要求:1) 1394 TA 控制的编解码器列表;2) 至少引用一个视频编解码器。 [外文原描述]: IEC 61883-8:2008+A1:2014 specifies a protocol for the transport of uncompressed or compressed video data in the 4:2:2 format of recommendation ITU-R BT.601 (including compatible extensions to this format for the higher and lower resolutions of other commonly used video resolutions) over high performance serial bus, as specified by IEEE Std 1394-1995 as amended by IEEE Std 1394a-2000 and IEEE Std 1394b-2002 (collectively IEEE 1394). The data formats for the encapsulation of video data are compatible with those specified by IEC 61883-1. Associated audio data, if any, should be formatted as specified by IEC 61883-6. This consolidated version consists of the first edition (2008) and its amendment 1 (2014). Therefore, no need to order amendment in addition to this publication.
