摘要:
When wireless communications are performed with other communication devices, an inquiry message to discover other communication devices residing in the vicinity is wirelessly transmitted by having communication ranges altered at a plurality of stages; response messages to the transmitted inquiry message are received; information relating to a receiving state or frequency of receipt of the response messages from the respective communication ranges is preserved with respect to each communication device which is a source of the response message; and based on the preserved information relating to the receiving state or the frequency of receipt of the response messages a communication device to be a connection object for wireless communication is selected. By doing so, when short-range wireless communications are performed, communication services can be performed appropriately between required devices.

This invention concerns a network comprising a master and slaves. In the network, each slave figures out its performance values as performance parameters and transmits the performance parameters to the master. The master performs a process of selecting a backup master as a candidate for the next master, on the basis of the performance parameters transmitted from the slaves. The master supplies BM information containing synchronization information and the address of the backup master selected, to the slaves. When the master is removed from the network, the slaves determine the next master in accordance with the backup-master information. Thus, the slaves can be immediately connected to the next master.

The present invention relates to a communication system, a communication method, an information processing apparatus, and an information processing method for easily and quickly organizing a communication group containing a plurality of apparatuses. The user places a PDA 2 in proximity to a personal computer 1. When an electromagnetic wave emitted from a reader/writer of the PDA 2 is received by a reader/writer of the personal computer 1, the personal computer 1 notifies the PDA 2 of stored communication group organizing information. The PDA 2 stores the communication group organizing information while establishing a synchronization for a Bluetooth communication with the personal computer 1 based on the communication group organizing information to establish the Bluetooth communication with the personal computer 1. The present invention is applicable to a variety of information processing apparatuses such as a personal computer and a PDA.

A slide show display system with BGM includes at least one content provision device that stores at least one of image content and music content, a playback device that plays back the image content and the music content, and an information processing device that controls the playback device to display a slide show with BGM. The information processing device includes a content information notification portion that transmits information on the image content and the music content that will be played back to the playback device, as well as a playback request portion that makes a playback request to the playback device to play back the content. The playback device includes a content acquisition portion that acquires the content from the at least one content provision device and a content playback portion that plays back the content in response to the playback request from the information processing device.

The present invention relates to a communication system and a method thereof, an information processing apparatus and a method thereof, an information processing terminal and a method thereof, which can start wireless communication easily and promptly. When an electromagnetic wave radiated from a reader/writer of a PDA 2 is received in a reader/writer of a personal computer 1, the personal computer 1 notifies the PDA 2 of device information stored therein. The PDA 2 establishes synchronization for Bluetooth communication with the personal computer 1 in accordance with a Bluetooth address contained in the device information and selects a service in accordance with a service record contained in the device information to establish communication via Bluetooth. The present invention can be applied to various information processing apparatuses such as a personal computer or a PDA.
