20120008678 | Quantization Control for Variable Bit Depth - The quantization parameter QP is well-known in digital video compression as an indication of picture quality. Digital symbols representing a moving image are quantized with a quantizing step that is a function QSN of the quantization parameter QP, which function QSN has been normalized to the most significant bit of the bit depth of the digital symbols. As a result, the effect of a given QP is essentially independent of bit depth a particular QP value has a standard effect on image quality, regardless of bit depth. The invention is useful, for example, in encoding and decoding at different bit depths, to generate compatible, bitstreams having different bit depths, and to allow different bit depths for different components of a video signal by compressing each with the same fidelity (i.e., the same QP). | 01-12-2012 |

20140327822 | Backwards-Compatible Delivery of Digital Cinema Content with Extended Dynamic Range - A digital cinema signal is encoded to produce a resulting coded digital cinema bitstream. Decoding the resulting coded digital cinema bitstream allows backwards-compatible delivery of digital cinema content.
