Method of processing video data from video presenter
First Claim
1. A method of displaying a video data stream including a plurality of alternating odd and even frames received from a video presenter, the method comprising the steps of:
- (a) receiving data of a first odd frame from the video data stream;
(b) processing the received data of the first odd frame (c) substantially simultaneously with step (b), receiving data of a first even frame adjacent said first odd frame;
(d) processing the received data of said first even frame; and
(e) substantially simultaneously with step (d), receiving data of a second odd frame subsequent to said first even frame.

Abstract
Provided is a method of processing video data in which a computer processes video data received from a video presenter, displays a moving picture, and captures a still picture when a still picture capture signal is generated. The method includes: (a) receiving data of an odd frame; (b) processing and displaying the received data of the odd frame and simultaneously receiving data of an even frame next to the odd frame; (c) processing and displaying the received data of the even frame and simultaneously receiving data of an odd frame next to the even frame; and (d) performing the (b) and the (c) repeatedly and alternately.

13. A method for displaying a high-speed video signal from a video presenter that communicates with a computer linked with a display, the method comprising:
-
initializing the computer for communication with the video presenter;
receiving a light at the video presenter that is reflected from a subject;
converting the light at the video presenter to a video data including a plurality of frame units;
storing the plurality of frame units to a memory of the video presenter;
at the computer, requesting a first frame unit from the video presenter;
storing the first frame unit in a first buffer of the video presenter;
first converting the first frame unit in the first buffer to a first format;
second converting the first frame unit in the first buffer from the first format to a second format;
outputting the first frame unit to a graphic device interface linked with the display substantially simultaneously with the first and second converting steps, requesting a second frame unit adjacent the first frame unit from the video presenter; and
substantially simultaneously with the outputting step, storing the second frame unit in a second buffer of the video presenter. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A system for presenting video data, the system comprising:
-
a video presenter comprising an optical system, a photoelectric converter in communication with the optical system, a signal processing unit linked with the photoelectric converter, a digital camera processor, a frame memory, a microprocessor and a first serial communication interface; and
a computer comprising a central processing unit executing a video data processing program and including a first buffer and a second buffer, a memory, a second serial communication interface and a graphic device interface, wherein, the optical system receives a light that is converted to a video signal by the photoelectric converter in cooperation with the digital camera processor, the digital camera processor storing the video signal in the frame memory, so that when the video presenter and the computer are linked by an interconnection means between the first and second serial communication interfaces the central processing unit requests a first frame from the microprocessor, stores the first frame in the first buffer, processes the first frame and outputs the first frame from the first buffer to the graphical device interface, and while the central processing unit processes and outputs the first frame the central processing unit also requests a second frame adjacent the first frame and stores said second frame to the second buffer.
