COMPUTATIONAL COMPLEXITY AND PRECISION CONTROL IN TRANSFORM-BASED DIGITAL MEDIA CODEC |
摘要 |
<p>A digital media encoder/decoder includes signaling of various modes relating to computation complexity and precision at decoding. The encoder may send a syntax element indicating arithmetic precision (e.g., using 16 or 32-bit operations) of the transform operations performed at decoding. The encoder also may signal whether to apply scaling at the decoder output, which permits a wider dynamic range of intermediate data at decoding, but adds to computational complexity due to the scaling operation.</p> |
