Abstract
A coder (e.g., an encoder or decoder) implements coding of two dimensional blocks of image data using two dimensional differential pulse code modulation (2D DPCM). The coder may switch between DPCM and other types of coding, such as transform coding on a block by block basis. The 2D DPCM may obtain a reconstructed pixel within the two dimensional bloc and code a second, different, pixel within the two dimensional block using the reconstructed pixel. The coder may also create a bitstream of entropy encoded residuals that supports hybrid implicit/explicit specification of coding parameters.
