Data processing apparatus, data processing method, and program

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.

主权项

1. A data processing apparatus comprising:
a memory configured to store, as a slot subject to extraction, at least a part of slots of a plurality of slots making up a frame that is a collection of said plurality of slots each providing a unit of error correction coding; and circuitry configured to
execute read/write control in which said slot subject to extraction of said plurality of slots in one frame is written to said memory and said slot subject to extraction of said one frame written to said memory is read within a preset unit time; output dummy data; and execute output processing in which, when said slot subject to extraction is changed, said dummy data is outputted with a timing immediately before a change start frame from which the change of said slot subject to extraction is started and, for frames subsequent to said change start frame, said slot subject to extraction read from said memory is outputted.
