Description
The present invention relates to an accelerator server, a set-top box and a cloud server for converting images.
Cloud computing technology refers to a technology that integrates and provides resources of computers in different physical locations into virtualization technology, unlike the existing computing environment, which depends on the independent hardware performance of each terminal.
An example of utilizing such cloud computing technology in IPTV (Internet Protocol Television) is VCS (Video Conference System) / ICS (transmitting a media stream in video / image form to a terminal and displaying it on the screen of the terminal using a decoder of the terminal). Internet Computing System) technology. In addition, there is a command-type virtualization technology that downloads a command including a resource of a user interface and implements it on the screen of the terminal.
Here, since VCS / ICS technology receives the original video and image from the cloud server in the terminal, only hardware-based video and image decoders and components for processing framebuffer objects and data packets are required. High performance of the terminal is required because the terminal directly decodes the resource of the image received by the command method and draws the decoded image.
Such a command-type virtualization technology may cause a problem of performance degradation in a situation in which more CPU and memory resources are required than the VCS / ICS technology.
Meanwhile, Korean Patent Publication No. 2010-0117709 discloses font data and a high resolution image corresponding to a maximum resolution of a display device, a screen resolution of a connected display device, and detects a screen resolution of a connected display device. Set the size of the menu frame buffer in the menu, load font data and high resolution images stored in the memory into the system memory, and load font data loaded into the system memory according to the screen resolution of the display device in response to a resizing command by a user operation. And a configuration in which the size of the high resolution image is adjusted and provided to the display device.
We want to calculate the scale factor for the original image conversion of the user interface requested by the set-top box.
