Abstract
A wireless network system capable of controlling highly efficient transfer of AV data by an upper application, using information indicating a wireless link condition that varies dynamically is disclosed. In this wireless network system, a wireless terminal and a wire gateway apparatus each store collected wireless link condition information in a descriptor. An upper application on the wireless terminal reads the descriptor at said terminal device and obtains wireless LAN link condition information. The wireless gateway apparatus makes notification to a wireless terminal of a VTR, for example, that actually exists in a 1394 terminal as if it existed as a sub-unit in the local terminal device. The wireless terminal accesses the collected wireless link condition information and selects a AV/C command to be sent to the VTR sub-unit of the wireless gateway apparatus. The wireless terminal transfers the play command for playback to the wireless gateway apparatus. The wireless gateway apparatus transfers the play command to a VTR sub-unit within a terminal on the wired network. In accordance with this action, the VTR sub-unit within the terminal on the wired network starts transfer of AV data.
