20120281005 | Method Of And Apparatus For Encoding And Decoding Data - Each block of texture data elements is encoded as a block of texture data that includes a set of integer values to be used to generate a set of base data values for the block, and a set of index values indicating how to use the base data values to generate data values for the texture data elements that the block represents. The integer values and the index values are both encoded in an encoded texture data block using a combination of base-n values, where n is greater than two, and base-2 values. Predefined bit representations are used to represent plural base-n values (n>2) collectively, and the bits of the bit representations representing the base-n values are interleaved with bits representing the base-2 values in the encoded texture data block. | 11-08-2012 |

20120281007 | Method Of And Apparatus For Encoding And Decoding Data - Each block of texture data elements is encoded as a block of texture data that includes: data indicating how to generate a set of data values to be used to generate data values for a set of the texture data elements that the block represents; data indicating a set of integer values to be used to generate the set of data values to be used to generate data values for a set of the texture data elements that the block represents; data indicating a set of index values indicating how to use the generated set of data values to generate data values for texture data elements of the set of texture data elements that the generated set of data values is to be used for; and data indicating the indexing scheme that has been used for the block. | 11-08-2012 |
20120281925 | Method Of And Apparatus For Encoding And Decoding Data - Each block of texture data elements is encoded as a block of texture data. The encoding process includes determining for each block of texture data elements whether the set of texture data elements of the block all have sufficiently similar data values. If they do, the extent of a region within the texture including the block in which every texture data element has sufficiently similar data values is then determined, and an encoded texture data block to represent the block of texture data elements that indicates that the block specifies a region within the texture in which every texture data element is to be allocated the same data value when decoded, and that includes data indicating the constant data value for the block and data indicating the extent of the region within the texture that the block relates to, is generated. | 11-08-2012 |
