Shared error resiliency path through coefficient reordering
Abstract:
The method, system, and apparatus of a shared error resiliency path through coefficient reordering is disclosed. In on embodiment, determining that an input data is data-partitioned, performing a discrete cosine transform and a quantization of the input data to form a quantized data, separating a first coefficient representing a DC coefficient of the quantized data for each block of the input data, rearranging other coefficients representing AC coefficients of the quantized data for each block of the input data in a fashion produces a zig-zag scan output similar to that of a non-data-partitioned data, bypassing a DC encoding module, determining whether any of the rearranged AC coefficients of the quantized data need to be encoded, performing a zig-zag scan on the rearranged AC coefficients of the quantized data when they need to be encoded, and encoding the rearranged AC coefficients of the quantized data based on the zig-zag scan.
