`ABSTRACT
`( 57 )
`While presenting on a display apparatus videos of high
`picture quality obtained from portable video processing
`apparatuses such as a camera and a cellular , it is possible to
`communicate with the Internet and / or a home network . A
`display apparatus includes a first radio communication unit
`capable of receiving video information by radio from an
`external video processing apparatus , a second radio com
`munication unit capable of connecting by radio to a network ,
`and a control unit for controlling assignment of connection
`by radio transmission for each of the first and second radio
`communication units . The control unit assigns connection of
`the first radio communication unit with higher priority and
`controls the assignment of the transmission rate such that the
`transmission rate between the first radio communication unit
`and the external video processing apparatus is more than that
`between the second radio communication unit and the
`network .
