Abstract: To provide an information processing device that is capable of enhancing reliability of detection processing of detecting a terminal. An information processing device includes: a first communication unit that transmits, by using a short-distance wireless communication function, a request to a terminal corresponding to identification information obtained beforehand; a determination unit that determines, on the basis of presence/absence of a response from the terminal corresponding to the identification information to the request, whether or not the terminal has been detected; and a second communication unit that transmits, to other devices, a detection result based on the determination of the determination unit.

Abstract: As shown in FIG. 7, the recording medium (e.g., non-transitory computer-readable storage medium) may not only be the removable media 231 having recorded therein a program which includes a magnetic disk (including a floppy disk), an optical disc (including a CD-ROM (Compack Disk-Read Only Memory) and a DVD (Digital Versatile Disk)), a mageto-optical disc (including an MD (Mini-Disk), a semiconductor memory, etc., and is deliver to a user for providing the program independently of the main part of the apparatus, but also be the ROM 222 or a hard disk contained in the storage section 228, on which the program is recorded and which is assembled into the main apparatus beforehand so as to be provided for the user.

Abstract: The present invention provides a system that can provide contents of reliable quality. The hold state is held until a holding time elapses. If a network congestion is detected within the holding time, the state is changed to a down state. When the holding time elapses, the state is changed to an up state. If it is found that there is no network congestion in the down state, the state is changed to the hold state. If it is found in the up state that the transmission rate reaches the maximum bit rate, the state is changed to the hold state. If any network congestion is detected in the up state, the state is changed to the down state.

Abstract: The present invention aims at providing transmission of video data over a network without missing the video data. The video data outputted from an input section is encoded by an encoder and then inputted into a TCP control section through a buffer. The TCP control section distributes the inputted data to reception apparatuses over a network such as the Internet. A rate control section detects an increase rate of the video data of the buffer and controls a transmission rate of the encoder according to the increase rate. The present invention can be applied to a transmission apparatus for transmitting the video data by way of a real-time delivery.

Abstract: An information processing apparatus includes a first receiver operable to receive predetermined information including a transmission state of data transmitted from another information processing apparatus, a congestion estimation unit operable to estimate congestion of a network on the basis of the predetermined information received by the first receiver, a control signal generator operable to generate a first control signal for controlling a data transmission rate of the another information processing apparatus based on the congestion estimated by the congestion estimation unit, and a first transmitter operable to transmit the first control signal generated by the control signal generator to the another information processing apparatus.
