    • Disclosed are a system, a method, and a computer program for reproducing high-quality image free from jerkiness even when the content reproducing speed is varied. The clock frequency set at a high level according as the content reproducing speed ascends is outputted from the system clock, and such variable clock signal outputted from the system clock is inputted to each processing section in charge of processing of content reproduction such as the data storage section, decoding section, buffer control section, output control section, and output display section. In these sections, processing of data is carried out by regulating the processing speed in accordance with the clock signal having a frequency conforming to the content reproducing speed. Such configuration allows all-frame variable-speed display without needing frame decimation operation even at a high-speed reproduction, for example, resulting in realization of reproduction of jerkiness-free, high-quality image.
    • 公开了一种系统,方法和计算机程序,即使在内容再现速度变化时,也可以再现高质量的图像,而不会出现抖动。 从系统时钟输出按照内容再现速度上升设定的高电平的时钟频率,并且从系统时钟输出的这种可变时钟信号被输入到负责诸如数据存储的内容再现处理的每个处理部分 部分,解码部分,缓冲器控制部分,输出控制部分和输出显示部分。 在这些部分中,通过根据具有符合内容再现速度的频率的时钟信号来调节处理速度来进行数据处理。 这种配置允许全帧可变速度显示,即使在高速再现时也不需要帧抽取操作,例如导致实现无抖动,高质量图像的再现。
