<p>Disclosed is a dynamic image transmission/reception device capable of establishing a two-way communication of high quality dynamic images between the 50 Hz area and the 60 Hz area, with a simple structure. A 50 Hz/60 Hz adjustment unit (21) acquires whether the operating frequency of the dynamic image transmission/reception device on the other side is 50 Hz or 60 Hz, from frequency information received from the other side. The 50 Hz/60 Hz adjustment unit (21) acquires the operating frequency of its own from a display unit (16) (or an input unit (20)), and determines whether the acquired operating frequency matches the operating frequency indicated by the frequency information. When the frequencies match, an interlaced dynamic image output from the input unit (20) is encoded by an encoding unit (22), and when the frequencies do not match, a progressive dynamic image obtained by subjecting the interlaced dynamic image to IP conversion in the input unit (20) is encoded by the encoding unit (22) to generate a progressive dynamic image stream. A transmission unit (23) transmits the encoded stream, and frequency information indicating the operating frequency of the dynamic image transmission/reception device (5) itself, to the other side.</p> |
