Abstract: A receiving device of the present disclosure includes: a first processor that (i) receives a broadcast signal obtained by modulating multiplexed data including at least first multiplexed data in a first multiplexing format, out of the first multiplexed data and second multiplexed data in a second multiplexing format different from the first multiplexing format, (ii) demodulates the broadcast signal received, and (iii) outputs the multiplexed data obtained as a result of the demodulation; and a converter that (i) converts, into the second multiplexing format, a multiplexing format of the first multiplexed data included in the multiplexed data that has been output, and (ii) outputs converted data obtained as a result of the conversion.

Abstract: A transmission device includes an image capturing part that captures a subject and generates a plurality of temporally successive frame images, an analyzer that analyzes a size of a motion of the subject by use of at least two or more of the frame images, a viewing condition receiver that receives viewing conditions from a reception device, and a network bandwidth measurement part that measures a congestion degree of a network. The transmission device further includes a controller that controls a data volume of the plurality of frame images based on the size of the motion of the subject, the viewing conditions, and the congestion degree of the network, to determine a predetermined parameter for encoding, an encoder that encodes the plurality of frame images based on the predetermined parameter, and a transmitter that transmits the plurality of encoded frame images.

Abstract: The present invention includes: a packet selection unit that selects predetermined packets from input transport packets; a packet deletion determination unit that determines whether or not to delete packets not selected by the packet selection unit; and a count unit that counts the predetermined number of the packets selected by the packet selection unit. It is therefore possible to record Null packets, which are not necessary in recording, at a requisite minimum every corresponding mode without deleting the Null packets. As a result, it is possible to maintain the same interval of the TS packets as that applied in receiving them.

Abstract: Versatility of a memory card is improved by providing a memory card where data protection mode and normal mode can be selected at discretion. A portable auxiliary storage device includes a mode setting section, a mode detecting section and a memory access control section. The mode setting section allows a user to set a normal mode permitting reading data stored in a memory section or writing the data to the memory section without restriction and a data protection mode for restricting the reading or writing. The mode detecting section detects a mode set in the mode setting section. The memory access control section controls the read or write according to a state of the mode setting section detected by the mode detecting section.
