Abstract:
1. A method of allowing a user of a communication terminal to instruct a content server to edit original content which is structured to include video content in the form of a series of video frames and which has been stored in the content server with which the communication terminal is communicable, the method comprising: a first step of converting, by the content server, the original content into proxy content that has a data size smaller than that of the original content, and that is viewed by the user of the communication terminal on the communication terminal, for instructing the content server to edit the original content without downloading the original content from the content server; a second step of transmitting, by the content server, the proxy content to the communication terminal; a third step of playing back, by the communication terminal, the proxy content, and of producing proxy-editing information in response to a user's editing operation on the communication terminal; a fourth step of transmitting, by the communication terminal, the proxy-editing information to the content server; and a fifth step of editing, by the content server, the original content in accordance with the proxy-editing information, wherein the original content further includes audio content represented by an audio signal, the first step includes: creating video content of the proxy content, by performing a frame decimation process in which ones of the video frames of the video content of the original content are extracted, such that the extracted video frames occur at a decimating video-frame-rate that is lower than an original video-frame-rate of the original content, the created video content of the proxy content being in the form of a series of the extracted video frames; creating audio content of the proxy content, by segmenting the audio signal of the audio content of the original content into a series of audio frames occurring at a frame rate substantially equal to the decimating video-frame-rate; calculating a series of sound levels representative of local audio signals of the series of audio frames; and correlating the calculated sound levels and respective video frames of the video content of the proxy content with each other, and the third step includes playing back the video content of the proxy content by displaying the video content on a display screen, and visualizing a time series of ones of the calculated series of sound levels, in association with a successively-selected one of the video frames which is displayed on the display screen.
