This paper introduces our implementation of a personal real-time live broadcast system. This system is comprised of three main components: the caster program, data manipulation program, and management program. The caster program is a client program running on the end user's personal computer equipped with a webcam. This program provides a convenient environment (cue sheet, prompts, reference image, buttons to control broadcasting) in which the user can create his video contents easily. The data manipulation program receives user's webcam video stream, combines the stream with the reference image and texts, then outputs HDMI, SID or RTSP as the manager directs. The management program manages broadcasting schedules, cue sheets, and users. User registration, user information modification, and deletion of a user are handled by the management program. A producer creates a broadcasting schedule (cue sheets) with the management program. One of the distinguished features of our personal real-time live broadcast system is its less than 1 second delay time.
