Abstract
Provided are a virtualization server for presentation virtualization and a method thereof. The virtualization server includes: a virtual layer management unit which generates a virtual screen for a user terminal; a service operation unit which executes a service requested from the user terminal, and displays a result of the executed service on the virtual screen; a screen division processing unit which divides the virtual screen into a plurality of sub-blocks; and an image data encoding unit which classifies the plurality of sub-blocks into image sub-blocks and text sub-blocks and encodes the image sub-blocks by a first encoding scheme and encodes the text sub-blocks by a second encoding scheme.
Claims20
A virtualization server for presentation virtualization, the server comprising:
- a virtual layer management unit which generates a virtual screen for a user terminal;
- a service operation unit which executes a service requested from the user terminal, and which displays a result of the executed service on the generated virtual screen;
- a screen division processing unit which divides the virtual screen into a plurality of sub-blocks;
- and
- an image data encoding unit which classifies a sub-block, of the plurality of sub-blocks, into one of an image sub-block and a text sub-block and which encodes image sub-blocks by a first encoding scheme and encodes text sub-blocks by a second encoding scheme.
An image data encoding method for presentation virtualization, the method comprising:
- acquiring information of a virtual screen to be transmitted to a user terminal;
- at a server, dividing the virtual screen into a plurality of sub-blocks;
- classifying a sub-block, of the plurality of sub-blocks, into one of an image sub-block and a text sub-block;
- and
- encoding the image sub-block by a first encoding scheme and encoding the text sub-block by a second encoding scheme.
An image data encoding method, the method comprising:
- at a server, dividing an image into a plurality of sub-blocks;
- classifying a sub-block, of the plurality of sub-blocks, into one of an image sub-block and a text sub-block;
- and
- encoding the sub-block by a first encoding scheme if the sub-block is classified as the image sub-block and encoding the sub-block by a second encoding scheme if the sub-block is classified as the text sub-block.
An image data decoding method for presentation virtualization, the method comprising:
- at a server, receiving, from a virtualization server for presentation virtualization, encoded image data of a virtual screen;
- determining whether a sub-block, of the received image data, is an image sub-block or a text sub-block;
- and
- decoding the sub-block by a first decoding scheme when the sub-block is determined as the image sub-block and decoding sub-block by a second decoding scheme when the sub-block is determined as the text sub-block.
