A plurality of access points for wireless communications and a management apparatus that manages the plurality of access points hold management information that indicates channels used by each of the plurality of access points and an assigning status of bandwidth for each channel. Then, a bandwidth assigning request issued from a wireless station newly connected to a first access point is received via the first access point and a determination is made, based on a bandwidth assigning status of a channel being used by the first access point, as to whether or not bandwidth requested in the bandwidth assigning request is assignable to the channel. When a determination of unassignable is made in the determination, control is conducted to execute exchanging of the channel of the first access point.

System and information processing method and apparatus

An image output apparatus has a communication unit which can communicate with a plurality of external devices, displays an image received from an external device through the communication unit, and acquires, from an external device serving as a provision source of the image being displayed, indication information related to sending of the image to an external device. The image output apparatus controls sending of the image being displayed to an external device other than the external device serving as the provision source on the basis of the acquired indication information.

Image output apparatus having a communication unit, and control method thereof

A communication system having first and second communication apparatuses, and communicates a communication frame obtained by time-division multiplexing a plurality of communication data, wherein the communication apparatus: receives first and second communication data; recognizes whether the first or second communication data is received; assembles a time-division multiplexed first communication frame using the communication data to add information indicating a format of the first communication frame to the first communication frame on the basis of a recognition result; and transmits the first communication frame assembled to the second communication apparatus, and the second communication apparatus receives the first communication frame transmitted; checks the format of the first communication frame on the basis of the information added to the first communication frame; and acquires the communication data from the first communication frame, on the basis of a checking result.

Communication system for communicating a plurality of time-division multiplexed data, and control method therefor

An audio message service apparatus comprises a first memory to store an encoded audio message, a second memory to store management data regarding the encoded audio message stored in the first memory and an encoder for again encoding the encoded audio message stored in the first memory by another different encoding method on the basis of the management data stored in the second memory and for storing the audio message which was again encoded into the first memory. The encoder encodes the encoded audio message by an encoding method of a higher compression ratio.

Audio message service apparatus

A telephone exchange system accommodates a plurality of central office lines and a plurality of telephones and records a telephonic communication in a recording area shared by the plurality of telephones. When predetermined conditions are satisfied, the recording is played back or transferred. The shared recording area can be utilized effectively by erasing a recording after it has been transferred, and by detecting the presence of a voice during a telephonic communication and starting and stopping the recording operation based upon the results of detection. The time at which a recording has been made can be comprehended in the form of a voice when the recording is played back.

Telephone exchange system

In a telephone apparatus which accommodates a plurality of lines and a plurality of terminals, system services in accordance with preset working data are realized based upon prescribed operations such as the dialing of an outgoing call from a terminal. The system services include the storing of desired dial information, the recording and playback of voice information from an outside provider of voice information, and the supplying of billing information.
