摘要： There are provided a transmitting section 308 for receiving program information representative of an outline and receiving condition of a receivable program and further receiving a program on the basis of the program information, and a zone-change determining section 307 for detecting a change of the program information. The program selecting section 309 causes the transmitting section 308 to suspend program reception and to switch a communication port, on the basis of a determination of a change of program distribution area by the zone-change determining section 307. Due to this, the transmitting section 308 is allowed to continuously receive the program so far received. This, in the case a program is provided at a communication port different based on each region, makes it possible to correctly receive a program even if moving traversing a region.

摘要： In a sending device (100), a fragmenting portion (101) fragments a bit stream according to the predicted relationship of the frames, and the output of the fragmenting portion (101) is allocated to either a TCP (Transmission Control Protocol) or a UDP (User Datagram Protocol) port. In an IP (Internet Protocol) layer, an encrypting portion (102) executes an encryption process only on the port to which bit stream corresponding to the I (Intra) frames is transmitted. In a receiving device (110), a decrypting portion (112) decrypts data on the port to which the bit stream corresponding to the I frames is transmitted, and a reassembling portion (111) restores the data to the original bit stream. This restoration is carried out by lining up the packets in increasing order of TR (Temporal Reference) value. Thus, the amount of time required for encryption and decryption is reduced compared to a case in which encryption is performed on all frames.

摘要： A media receiving apparatus capable of preventing media from being positioned in an invalid display area or a program from being temporarily stopped, even if the vertical/horizontal ratio of the resolution of the display section is switched while a broadcast or streaming program is being displayed. In this apparatus there are a plurality of display sections D1 and D2 with different resolutions, and a display directive section (303) directs a display section to be set as active in accordance with the mode of use of the user. A layout information selection section (304) selects a layout corresponding to the resolution of the display section indicated by the display directive section (303) from layout information that includes layouts corresponding to display sections D1 and D2 distributed from a media distribution apparatus, and in accordance with the selected layout a media display control section (306) selects media distributed from the media distribution apparatus, performs conversion processing comprising enlargement or reduction, and displays media on the display section designated by the display directive section (303).

摘要： In a sending terminal (10), a propagation delay measurement portion (102) uses propagation delay time measurement packets to measure the round trip time to/from an intermediate node of intermediate nodes (12, 13, 14) with the potential of becoming a bottleneck. Based on the results of this measurement, a transmission rate determining portion (104) determines the transmission rate of the data, and a data sending portion (100) sends the data at the determined transmission rate.
