Abstract
This paper describes a dynamic image control function on video communication system for agricultural informatics. The video communication system is used for remote diagnosis of diseases and pests and remote observation of remotely located fields. The main feature of the proposed function is that the function can dynamically control size and quality of video images according to a user's demands and purposes. The proposed function does not need to adjust QoS parameters. Furthermore, the proposed function can transmit the video images effectively for an assigned network by controlling the QoS parameters to fit them into the network. We experimented on three different bandwidth networks using the proposed function. From experimental results, we verified that the proposed function worked finely on any bandwidth and transmits the video images to the best on the assigned network bandwidth.
