The playback method includes a first step of outputting stereo audio signals using the monaural audio signal if the necessary stereo process information is not supplied; a second step of starting updating stereo variables within filters, and outputting the stereo audio signals using the monaural audio signal until all the state variables are updated, if the necessary stereo process information is supplied; and a third step of performing the stereo process based on stereo process information acquired by the necessary stereo process information, on the monaural audio signal to generate and output stereo audio signals, if all the state variables within the filters are updated.

该再生方法包括：第一步骤，如果没有提供立体声处理必需信息，则输出使用了非立体声音频信号的立体声音频信号；第二步骤，如果提供了立体声处理必需信息，则开始更新滤波器内的状态变量，并输出使用了非立体声音频信号的立体声音频信号，直到更新完所有的状态变量；以及第三步骤，如果更新完滤波器内的所述状态变量，则对非立体声音频信号执行基于通过立体声处理必需信息获取的立体声处理信息的立体声处理，并生成并输出立体声音频信号。

A telesync is the same spec as a CAM except it uses an external audio source (most likely an audio jack in the chair for hard of hearing people). A direct audio source does not ensure a good quality audio source, as a lot of background noise can interfere. A lot of the times a telesync is filmed in an empty cinema or from the projection booth with a professional camera, giving a better picture quality. Quality ranges drastically, check the sample before downloading the full release. A hellogh percentage of Telesyncs are CAMs that have been mislabeled.

除了使用外置的音源（通常为影院椅子上为听力欠好的人设的耳机孔），TELESYSNC 和CAM的标准是相同的这个直接的音源并不能保证是好的音源，这是它因为受到很多配景噪音的干扰很很长时间候TS是在空的影院录制，或是用专业摄像机在投影室录制，以是图像质量有可能比CAM好质量的升沉有可能很大，在下载前最佳查看SAMPLE很大比例的TS是从CAM纰缪标志成
