dolby ac meaning in English
杜比数位
Examples
- Hdtv video decoder is a key component of high definition television receiver . as audio compression standard of atsc - hdtv , dolby ac - 3 is a high - quality , low - complexity multichannel audio coder which is used for more and more applications
作为atsc - hdtv系统的声音制式标准，杜比ac - 3是一种高质量、低复杂度的多声道声音编码压缩技术，被越来越多的应用到各种场合。 - Second , this dissertation implements separately a mpeg - 2 video decoder and a dolby ac - 3 digital audio decoder based on software mode , and gives a audio & video synchronization algorithm based on audio - clock - benchmark in mpeg - 2 system decoder , whose feasibility and practicability have been proved by experimenting . it is an all - purpose algorithm , which can perform different decoder according to mpeg - 1 or mpeg - 2 system models , and can also be used for reference to the implementation of other multiplex stream decoders
然后，论文实现了基于软件方式的mpeg - 2标准视频及ac - 3格式压缩音频的实时解码与回放，并依据mpeg - 2系统解码模型实现了一种基于音频基准时钟的mpeg解码器的视音频同步算法，实验证明该算法可行、实用、通用性好，对符合mpeg - 1或mpeg - 2系统标准的视音频解码器均具适用性。 - For details below : 1 ) video changed from mpeg2 ps to mpeg2 ts 2 ) audio of ntsc format that can not be decoded by stb could be changed from dolby acs coding standard to mpeg1 / 2 layerll standard , and packed into mpeg2 ts format 3 ) well synchronized with audio and video by a new arithmetic " successive time stamp " this thesis made a introduction of mpeg2 standard in detail ; discussed the system timing model ; indicated the key during the transforming of video and audio ; especially explain how to deal with the pcr
2 )针对目前机顶盒不能解码的ntsc制式dolbyac3编码算法音频信息，转换成mpeg1 2layer编码，并打成满足mpeg2ts语法的信息包。 3 )提出了能使音视频达到良好同步的继承性时间标签打入算法本文详细介绍了mpeg2标准的语法，讨论了mpeg2系统的时间模型从而指出视音频处理中的关键，对pcr的处理进行了详细的分析，提出了新的视、音频同步算法。
