Abstract:
1. A transmission device which transmits a plurality of encoded frame images to a reception device connected through a network, the transmission device comprising: an image capturing part that captures a subject and generates a plurality of temporally successive frame images; an analyzer that analyzes a size of a motion of the subject by use of at least two or more of the frame images generated in the image capturing part; a viewing condition receiver that receives viewing conditions from the reception device; a network bandwidth measurement part that measures a congestion degree of the network; a controller that controls a data volume of the plurality of frame images generated in the image capturing part based on the size of the motion of the subject, the viewing conditions, and the congestion degree of the network, to determine a predetermined parameter for encoding; an encoder that encodes the plurality of frame images based on the predetermined parameter; and a transmitter that transmits the plurality of encoded frame images.
