The Broadcast News Transcription System
Realization of "human-friendly broadcasting" is important in order to make available broadcasting services for the elderly or hearing impaired. Expanding closed-captioned broadcasts is one of the means to accomplish this. To meet the demands for this news program closed-captioning service, our Laboratories have been developing a broadcast news transcription system which can recognize an announcer's speech and automatically create a caption with which the broadcast may be subtitled.
The broadcast news transcription system recognizes the announcer's speech and creates a caption with natural Japanese sentences using the appropriate Kanji and Kana characters. The system's characteristics are as follows:
Moreover, a time delay of no more than 5 seconds between the announcer and the closed-captioning is desirable. The reviewing and correction process takes about 3 seconds, which leaves a delay of less than 2 seconds available for recognition.
Field Emitter Image Sensor with HARP target
Field emitter array :A field emitter array is a two-dimensional matrix electron source consisting of many small pixels. Each pixel includes a one tip or many tips micro-miniature field emitter.
The field emitter is fabricated by IC technology, and electrons are emitted from each tip by applying voltage (electric-field). The field emitter has many advantages, such as low power consumption and high emission current density, compared to the conventional thermal cathode.
