Title: CLOUD STREAMING SERVICE SYSTEM, IMAGE CLOUD STREAMING SERVICE METHOD BASED ON TRANSPARENCY OF IMAGE, AND APPARATUS THEREFOR
Abstract:
A cloud streaming service system, an image cloud streaming service method based on the transparency of the image, and an apparatus therefor are disclosed. A plurality of frames corresponding to an application execution screen are compared to capture an image, the transparency of the image is checked on the basis of an alpha value corresponding to the image, if the transparency is not consistent, the image is divided into at least one region based on the transparency, and the at least one region may be encoded as still images by the still image encoding technique corresponding to each of the at least one region to be streamed to the user terminal. Accordingly, the captured images can be encoded more naturally and effectively in an image-based cloud streaming service.
