Multimedia network picture-in-picture

摘要

A content server consistent with certain embodiments of the present invention has a mechanism for receiving a picture-in-picture communication to initiate a picture-in-picture function. A video image scaler, responsive to the picture-in-picture communication, scales a secondary video image to produce a reduced size secondary video image. A secondary video image embedder embeds the reduced size secondary video image into a main video image to produce a picture-in-picture video image. A video encoder encodes the analog picture-in-picture video image into a digital video format to produce a digital picture-in-picture video image. A packetizer and streamer packetizes the digital picture-in-picture video image into Internet protocol (IP) packets to form a packetized data stream and addresses the Internet protocol packets to the target networked device prior to transmitting.
