Description

Technical field

[0001] The invention relates to a method and system for encoding and transmitting JPEG2000 images, in particular to a method and system for encoding and transmitting images on a device based on EP1C12Q240C8 and S3C4510B embedded platforms. Background technique

[0002] The JPEG2000 standard is a high-quality still image coding standard that can provide image coding and decoding algorithms with different compression qualities from lossless to lossy. With the development of multimedia and network technology, network image transmission has been widely used.

[0003] Because the JPEG2000 coding standard compresses images with high quality and complex algorithms, the current traditional coding systems are implemented using PC-based computer platforms or high-end MCUs based on embedded operating systems. The equipment is huge and complex, with high cost, low operating speed and low execution efficiency. . With the civilianization and popularization of the application of...
