Overview

We have developed "highlight playback technology" which detects the most exciting highlights of sports programs and automatically plays back a summary. The large-capacity hard disk enables long recording and playback of sports coverage summaries as and when you choose.

Technology Point

World's first *1 automatic sports summary playback function

Mitsubishi Electric has developed the world's first "highlight playback technology" which automatically detects the most exciting highlights of sports programs and automatically plays back a recorded summary.

Automatic highlight detection using audio analysis

Audio analysis focuses on elements such as the announcer's voice and audience's cheering, and the exciting parts are displayed as a graph. Audio analysis enables high precision detection even if the type of sport, country and spoken language are different.

Summary of the programs for the length of time you want to watch them

By looking at the graph showing the highlights, it is possible to choose the length of the summary. For example, 2 hours of soccer coverage could be summarized into just five minutes of goal action.

Music playback function

Mitsubishi Electric has developed a song playback technology that detects only the musical performance scenes (music) in music programs.

Playback of only songs and musical performances in music programs

By playing back only the music portions of music programs back to back, you can enjoy an original music video clip consisting exclusively of songs and musical performances. Such music scenes can also be dubbed to a disc.
