- PNG portable network graphics
- PNG palletized portable network graphics
- JPEG joint photography experts group
- the image quality is good when encoding, but when the bandwidth of the transmission network is low due to the large data size, the transmission speed may be reduced.
- Palletized PNG still image compression reduces the data size of the image during encoding, which guarantees transmission speed, but degrades image quality due to the 8-bit color representation.
- the JPEG still image compression technique has a high compression efficiency and can greatly reduce the amount of data transmitted during encoding.
- the high compression efficiency can cause a large system load when encoding and decoding.
- the image cloud streaming service method using the application code is generated to include the animation information by converting the still image-encoded capture image and the first code to generate the application result screen in the user terminal
- the second code is transmitted to the user terminal to perform a cloud streaming service based on a still image (S740).
