An address of a terminal on a network is fixed during the session. The present invention provides an electronic apparatus that can be connected to a network, including, a communication unit communicating with another electronic apparatus existing on the network, a temporary-address setting unit setting a temporary address that is temporarily valid on the network, an address-requesting unit requesting that an address management apparatus connected to the network should set an address at a predetermined timing, when the temporary address is set, and an address-request stopping unit inhibiting the address-requesting unit from operating, while the communication unit is communicating with the other electronic apparatus, by using the temporary address.

Electronic apparatus having communication function and control method

A mutual recognition process is performed in step S. When it is determined in step Sthat a request for sending a list of musical pieces has been received, the list of musical pieces is sent in step S. When a request for sending audio data has been received in step S, a transfer-rate measurement process is executed in step S. When it is determined according to the transfer rate in step Sthat the audio can be transmitted, the corresponding compressed audio data is extracted in step S, the compressed audio data is decoded to generate linear PCM data suited to the transfer rate in step S, and transmitted in step S. When the audio data cannot be transmitted, an error message is transmitted in step S. The present invention can be applied, for example, to a server for distributing audio data and an audio player terminal for reproducing the distributed audio data.

Data stream-distribution system and method therefor

A sound-field production apparatus includes a direct-sound-generating unit for generating a direct sound from a sound signal supplied to the direct-sound-generating unit and a reflected-sound-generating unit for generating a sound serving as a substitute for a sound obtained as a result of reflection of the direct sound at a level lower than the direct sound with a timing lagging behind the direct sound from the sound signal supplied to the reflected-sound generating unit. The sound-field production apparatus makes it possible to reproduce an impressive sound field that gives a better feeling of presence on the scene as a sound field in a movie theater or the like does by creating a sound-field space having an effect of sound-image broadening.
