Patent ID: 8169913

Claim:
A communication-processing method that performs communication processing on network-connected equipment, the method comprising: sending an identification signal to every apparatus connected to a local area network (LAN) to identify a local apparatus; determining whether a reply signal including identification information in reply to the sent identification signal is received or not; deciding that the local apparatus is connected to the LAN if receiving the reply signal including the identification information; deciding that the local apparatus is not connected to the LAN if receiving no reply signal including the identification information; selecting a communication-processing condition for the identified local apparatus based on the deciding whether the local apparatus is connected to the LAN, wherein the selecting a communication-processing condition includes selecting User Datagram Protocol (UDP) and a first bit rate for communication with the identified local apparatus when it is decided that the identified local apparatus is connected to the LAN and selecting Real-time Transport Protocol (RTP) and a second bit rate, which is less than the first bit rate for communication with the identified local apparatus when it is decided that the identified local apparatus is not connected to the LAN; communicating with the identified local apparatus via the LAN using UDP and the first bit rate when it is decided that the local apparatus is connected to the LAN, and communicating with the local apparatus after connection to the Internet using RTP and the second bit rate when it is decided that the local apparatus is not connected to the LAN; and receiving video content from the local apparatus, the video content including accompanying information for controlling the reproduction of the video content, wherein the accompanying information includes copy guard information and information relative to a wide-detection signal for switching a display image size.
