Patent ID: 7512087

Claim:
A communication method for communicating between a first communication apparatus and a second communication apparatus, comprising: forming a plurality of communication networks between the first communication apparatus and the second communication apparatus; measuring, upon starting communication between said first apparatus and said second apparatus, communication quality of said communication networks using at least one of said communication apparatus; and selecting one of said communication networks to be used for the communication, based on: the measured communication quality; and an ability to execute an application program for transmission of high speed video data, wherein said communication quality is measured by the second communication apparatus by: sending test data to the first communication apparatus in response to a request; receiving re-sent test data from the first communication apparatus; comparing the sent test data to the received re-sent test data; and determining the communication quality as a function of errors detected in comparison; or wherein said communication quality is measured by the first communication apparatus by: sending a request for transmission of test data; receiving test data from the second communication apparatus in response to the request; comparing received test data to stored test data; and determining the communication quality as a function of errors detected in comparison.
