Method and apparatus for encoding of bitstreams using rotation

A method of encoding a stream of data points comprising:

• encoding a stream of data points to form a plurality of blocks of encoded data;
• and
• altering at least one block parameter of a second block by using a factor that is dependent on a bitstream parameter of a first block, said block parameter representative of the encoding of data points of the block and said bitstream parameter representative of how bits are utilized to encode the first block such that if the bitstream parameter of the first block is lost the factor may be used to estimate the bitstream parameter of the first block.

A computer readable medium containing executable instructions, which, when executed in a processing system, causes the system to perform the steps for encoding data, comprising:

• calculating a rotation factor from a selected data of a first block;
• and
• altering a selected data of a second block in accordance with the rotation factor such that if the selected data of the first block is lost the rotation factor may be used to estimate the selected date of the first block.
