Embodiment Construction

[0028] Embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 10 .

[0029] (remote distribution system)

[0030] FIG. 1 is a system schematic diagram of a remote distribution system 1 according to an embodiment of the present invention. The remote distribution system 1 is respectively connected to the host side 100, the server room 200, and the client side 300 via the Internet protocol, and the contents of the lectures given by the lecturer can be distributed to the attendees at remote locations in real time or on demand.

[0031] Here, the host side 100 refers to a classroom, a meeting room, or the like where a lecturer (or speaker) actually gives a lecture (or a lecture). The host side 100 is composed of at least a host terminal 10, an encoder terminal 20, a screen 30, a projector 40, a pointer position detection camera 50, a lecturer camera 60, a laser pointer 70 held by the lecturer, and a whiteboard 80. .

[0032]The host t...

Abstract

A remote delivery system for delivering a lecture content given by an instructor to a remote location preliminarily, converts an instructor's document to an animation file, delivers to a student's terminal, automatically delivers, from the starting of a lecture, image sound data including an image and sound of the instructor, the number of the instructor's document selected by the instructor, location data of a pointer on a screen, character or figure data drawn on a whiteboard by the instructor and animation information included in the instructor's document, and displays on the student's terminal in real time by comparing an instructor document number and an animation information number preliminarily written in the animation file with delivered numbers.

Description

technical field [0001] The present invention relates to a remote distribution system and a remote distribution method for distributing lectures in real time or on demand to listeners at remote locations using a communication network. Background technique [0002] The existing remote distribution system and remote distribution method have been disclosed in JP-A-2000-250392. The remote distribution system and remote distribution method acquire the content of lectures given by lecturers in schools, companies, lectures, etc. as video data and audio data, and provide them to attendees at remote locations via a network. [0003] In this remote distribution system, a lecturer needs to give lectures to a terminal device (PC) for distribution. In addition, in this remote distribution system, there is a restriction that a dedicated application for distribution must be operated. Therefore, there is a problem that the burden of operation on the instructor side is heavy. [0004] Also...
