Information processor and method for processing information
First Claim
1. A first information processor connected to a network with another information processor having a record medium recorded with a video stream, the first information processor comprising:
- a command generator operable to generate a command requesting the another information processor to extract and produce a specified video frame of the video stream recorded in the record medium, and to send the video frame after converting it into still image data;
a command sender operable to send the command to the another information processor; and
an image data receiver operable to receive the still image data from the another information processor.

Abstract
According to the present invention, it is possible to extract a specified video frame as a still image from a video stream recorded in a record medium of another information processor. A sender information processor sends to a receiver information processor connected to a network a command to extract and generate a specified video frame of a video stream recorded in a record medium, and then to send the video frame to the sender after converting the video frame into still image data. The receiver extracts and generates a requested video frame based on the command, and obtains still image data from the video frame. Then, the receiver sends the still image data to the sender. In this case, the receiver extracts and generates a video frame which corresponds to the video frame specification information included in the command, so as to obtain still image data which corresponds to the image format and size information included in the command. The sender receives the still image data from the receiver.
