SYSTEM FOR CLOUD STREAMING SERVICE, METHOD FOR STILL IMAGE-BASED CLOUD STREAMING SERVICE AND APPARATUS THEREFOR
First Claim
1. A cloud streaming server comprising:
- a capture unit configured to capture a changed region contained in a changed frame in comparison with a previous frame;
an encoding unit configured to select a still image compression technique by considering one or more of a size of the changed region and an image type corresponding to the changed region, and to perform a still image encoding of the changed region corresponding to one frame by using the selected still image compression technique; and
a sending unit configured to perform a cloud streaming service based on a still image by sending the still-image-encoded changed region to a user.

Abstract
The present invention relates to a system for a cloud streaming service, a method for a still image-based cloud streaming service and an apparatus therefor. The still image-based cloud streaming service can be provided by capturing the changed area in the changed frame by comparing same with the previous frame, selecting a still-image compression technique by considering any one or more from among the size of the changed area and image characteristics, and transmitting, to a user, the changed area encoded by the still-image compression technique. When providing a still image-based cloud streaming service, by utilizing still-image compression techniques which are appropriate to the conditions, the compression efficiency of the still image and speed of the cloud streaming service can be improved.

11. A cloud streaming server comprising:
-
a capture unit configured to capture a changed region contained in a changed frame in comparison with a previous frame; an encoding unit configured to select a still image compression technique in accordance with an image type determined by considering one or more of the number of colors of an image corresponding to the changed region and a standard deviation of pixel values of the image, and to perform a still image encoding of the changed region corresponding to one frame by using the selected still image compression technique; and a sending unit configured to perform a cloud streaming service based on a still image by sending the still-image-encoded changed region to a user. - View Dependent Claims (12, 13, 14, 15)
