    摘要: 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.

    摘要: A frame synchronizer, frame synchronization method and demodulator which can more positively establish frame synchronization of an input signal which is likely to have a plurality of frame lengths. A differential correlation detector calculates a differential correlation value with no pilot which is associated with the absence of a pilot signal inserted in the input signal and a differential correlation value with a pilot which is associated with the presence of a pilot signal inserted in the input signal. Frame period confirmation counters perform, based on the differential correlation values with no pilot, frame synchronization control appropriate to the input signals whose frame lengths are 21690 and 32490 symbols, respectively. The frame period confirmation counters 1 perform, based on the differential correlation values with a pilot, frame synchronization control appropriate to the input signals whose frame lengths are 22194 and 33282 symbols, respectively.
