Routing schemes are provided for a communication network. In one scheme, destination terminals and associated neighboring terminals are listed in a routing control cache at each communication terminal in the network, and packets are routed toward the destination terminal through the associated neighboring terminals. In another scheme, a single path from a source terminal to a destination terminal is automatically expanded into multiple paths. In yet another scheme, packets are routed as long as this does not increase the number of hops to the destination terminal. These schemes enable multiple paths to be established by a simple procedure not requiring complex distance calculations. In still another scheme, routing is restricted to the shortest path and paths up to a given number of hops longer than the shortest path, permitting paths to diverge in multiple directions from the source and destination terminals.

PROBLEM TO BE SOLVED: To freely edit video contents in a short time by the intention of an end user. SOLUTION: A video contents analyzer 82 analyzes contents of an original video image, and a contents-providing device 83 provides a particular scene extracted from the contents. When an edit instruction is sent, while confirming the provided particular scene, a video configuration device 89 provides an edited object video image resulting from applying edit processing to the original image along with the edit instruction this time. Upon the receipt of revision of edit processing, a new edited object video image subjected to revised edit processing is provided to an end user. When receiving an edit processing end instruction, the edited object video image provided, immediately prior to this is converted into a desired format and the resulting image is distributed as the edited video image.
