Picture codec and teleconference terminal equipment.

摘要

In a teleconference terminal equipment; a picture codec (in Fig. 2) for simultaneously displaying a still picture and video on a single screen, comprising an analog-to-digital converter (200) which converts a picture signal into digital picture data, a picture-in-picture processor (205) which is supplied with the digital picture data as self-picture data of the terminal equipment, a video decoder (206) or a still picture decoder (207) which decodes input picture data and delivers the decoded data to the P-in-P processor (205), and a digital-to-analog converter (220) which is supplied with picture data for forming a P-in-P frame, having been produced from the self-picture data and the decoded data by the P-in-P processor (205), and which converts the supplied picture data into an analog signal and delivers the analog signal as an output.
