    • Digest playback apparatus and method for a VCR. The digest playback apparatus includes a system controller for outputting a plurality of control signals to control the entire operation of a video cassette recorder system, the plurality of control signals including speed-change multispeed and direction data and audio multispeed change mode ON/OFF data. An analog/digital conversion circuit converts an analog audio signal read by an audio head and then restored to its original state into digital audio data regardless of a speed-change mode. A memory stores the digital audio data from the analog/digital conversion circuit. A digital/analog conversion circuit converts the digital audio data stored in the memory into an analog audio signal, and a control circuit controls the analog/digital conversion circuit, the memory and the digital/analog conversion circuit to output the analog audio signal from the digital/analog conversion circuit as a 1 multispeed which allows the user to accurately listen to the output analog audio signal.
    • 用于录像机的摘要播放装置和方法。 摘要回放装置包括:系统控制器,用于输出多个控制信号以控制盒式磁带录像机系统的整体操作,所述多个控制信号包括变速多速和方向数据以及音频多速变速模式ON / OFF数据。 模拟/数字转换电路转换由音频头读取的模拟音频信号,然后将其恢复到其原始状态到数字音频数据,而不管速度变化模式如何。 存储器存储来自模拟/数字转换电路的数字音频数据。 数字/模拟转换电路将存储在存储器中的数字音频数据转换成模拟音频信号,并且控制电路控制模/数转换电路,存储器和数/模转换电路,以从模拟音频信号输出模拟音频信号 数字/模拟转换电路作为1个多速度,允许用户准确地收听输出的模拟音频信号。
