    • A data processing apparatus, a data processing method, and a program that are configured to prevent (or lower) the increase in scale and cost of the apparatus. A read/write control portion executes read/write control in which slots subject to extraction of two or more slots in one frame that is a collection of two or more slots each of which is a unit of error correction coding are written to a ring buffer and the slots subject to extraction in one frame written to the ring buffer are read within the unit time. When slots subject to extraction are changed, an output portion executes output processing in which dummy data outputted from a dummy data output portion are outputted with a timing immediately before a change start frame that is a frame from which the change of slots subject to extraction is started and, slots subject to extraction read from the ring buffer are outputted for frames subsequent to the change start frame. The present disclosure is applicable to reception apparatuses for receiving BS digital broadcasting, for example.
    • 一种数据处理装置,数据处理方法和程序,被配置为防止(或降低)装置的规模和成本的增加。 读/写控制部分执行读/写控制,其中在一帧中作为两个或更多个时隙的集合的两个或更多个时隙中的两个或更多个时隙被提取的时隙,每个时隙都是纠错编码的单位,被写入环形缓冲器 并且在单位时间内读取在写入环形缓冲器的一帧中被提取的时隙。 当进行提取的时隙发生改变时,输出部分执行输出处理,其中从伪数据输出部分输出的虚拟数据以紧邻改变开始帧之前的定时被输出,该改变开始帧是从其提取的时隙的改变是 开始,并且从改变开始帧之后的帧输出从环形缓冲器读取的提取的时隙。 例如,本公开可应用于接收BS数字广播的接收装置。
