Data coding buffer for electrical computers and digital data processing systems
View Patent ↗A method of buffering includes determining, based at least in part on a radix of a data symbol, a number of discrete values resulting from coding the data symbol into a buffer. The number of discrete values is compared with a buffer capacity of the buffer. The buffer is scaled based at least in part on the radix of the data symbol if the number of discrete values does not exceed the buffer capacity of the buffer. The data symbol is coded into the scaled buffer if the number of discrete values does not exceed the buffer capacity of the buffer.
1. A method of buffering comprising:
determining a number of discrete values resulting from coding a data symbol into a buffer based at least in part on a radix of the data symbol;
comparing the number of discrete values with a buffer capacity of the buffer;
scaling the buffer based at least in part on the radix of the data symbol if the number of discrete values does not exceed the buffer capacity of the buffer; and
coding the data symbol into the scaled buffer if the number of discrete values does not exceed the buffer capacity of the buffer.
2. The method of claim 1 , further comprising:
sending the coded data symbol from the buffer to a decoder;
initializing the buffer to zero; and
coding a second data symbol into the initialized buffer, wherein the data symbol and the second data symbol are part of a sequence of data symbols.
3. The method of claim 1 , wherein the number of discrete values is determined based at least in part on a comparison of the radix of the data symbol with an accumulated radix of previously coded data symbols.
4. The method of claim 3 , wherein the data symbol is part of a sequence of data symbols, and further wherein the sequence of data symbols comprises mixed radix data symbols.
5. The method of claim 1 , further comprising altering the buffer capacity of the buffer in response to the comparing.
6. The method of claim 5 , wherein the altering comprises increasing the buffer capacity of the buffer to accommodate at least a portion of the coded data symbol.
7. The method of claim 1 , further comprising providing the buffer to a decoder if the number of discrete values exceeds the buffer capacity of the buffer.
8. The method of claim 7 , wherein a length of the buffer is known by the decoder prior to receipt of the buffer by the decoder.
9. The method of claim 1 , wherein the data symbol is part of a sequence of data symbols, wherein the sequence of data symbols comprises a second part of a code resulting from combinatorial coding.
10. The method of claim 1 , wherein the data symbol is part of a sequence of data symbols, and further wherein the sequence of data symbols represents at least a portion of an audio stream or a video stream.
