Data processor and communication system
First Claim
1. A data processor for managing a bandwidth for use by an electronic device participating in a communication network, comprising:
- a wireless communication section communicating with the electronic device anda bandwidth management section performing control to variably allocate, based on a request from the electronic device, a bandwidth to be used for communication performed by the electronic device,wherein the bandwidth management section comprises a bandwidth management table and performs bandwidth allocation control by referring to information recorded in the bandwidth management table,wherein the bandwidth management table comprises a field for holding information for use in managing the bandwidth for the electronic device,wherein the bandwidth management section records, upon recognizing an additional electronic device, identification information identifying the additional electronic device and attribute information about data to be transmitted by the additional electronic device as new entry data in the bandwidth management table,wherein the identification information represents a MAC address, and the attribute information represents a usable data format, andwherein the MAC address information and the usable data format information is information contained in beacon information included in a superframe used in UWB communication.

Abstract
A data processor which can flexibly control bandwidth settings and setting changes is provided. The data processor controls bandwidth allocation to electronic devices participating in a communication network. The data processor has a communication section used to communicate with the electronic devices and a bandwidth management section which performs control to variably allocate, based on requests from the electronic devices, bandwidths to be used for communication by the electronic devices. In cases where an additional device is added to the communication network and an adequate bandwidth cannot be allocated to the additional device, the bandwidth management section requests another electronic device transmitting video data of a resolution higher than corresponding to the user'"'"'s intention to change its data format so as to allow an adequate bandwidth to be allocated to the additional device.

a wireless communication section communicating with the electronic device and a bandwidth management section performing control to variably allocate, based on a request from the electronic device, a bandwidth to be used for communication performed by the electronic device, wherein the bandwidth management table comprises a bandwidth management table and performs bandwidth allocation control by referring to information recorded in the bandwidth management table, wherein the bandwidth management table comprises a field for holding information for use in managing the bandwidth for the electronic device, wherein the bandwidth management section records, upon recognizing an additional electronic device, identification information identifying the additional electronic device and attribute information about data to be transmitted by the additional electronic device as new entry data in the bandwidth management table, and wherein, when a bandwidth acquisition command is received from the electronic device;
the bandwidth management section determines, by referring to the bandwidth management table, whether or not a requested bandwidth can be acquired and requests, as required, another electronic device to change the bandwidth used thereby or discontinue communication being performed thereby; and
, when it is determined that the request made by the bandwidth acquisition command can be met, the bandwidth management section updates entry data corresponding to the electronic device recorded in the bandwidth management table with information about the bandwidth that can be acquired for the electronic device and information about the destination address for transmission to be made using the bandwidth whereas, when it is determined that the request cannot be met, the bandwidth management section sends a notice of that effect to the electronic device having issued the bandwidth acquisition command. - View Dependent Claims (3, 4, 5, 6, 7)
