In a method to improve backwards compatibility when decoding high-dynamic range images coded in a wide color gamut (WCG) space which may not be compatible with legacy color spaces, hue and / or saturation values of images in an image database are computed for both a legacy color space (say, YCbCr-gamma) and a preferred WCG color space (say, IPT-PQ). Based on a cost function, a reshaped color space is computed so that the distance between the hue values in the legacy color space and rotated hue values in the preferred color space is minimized. HDR images are coded in the reshaped color space. Legacy devices can still decode standard dynamic range images assuming they are coded in the legacy color space, while updated devices can use color reshaping information to decode HDR images in the preferred color space at full dynamic range.

Techniques are directed to an audio codec configured to process audio in such a way that enables the codec to decompress an encoded audio signal at an increased bandwidth and / or bit depth. In some implementations, the audio codec is configured to operate on audio data expressed in the Opus format. In such implementations, the Opus format enables such decompression at increased bandwidth while preserving backward compatibility with standard decompression in the Opus format. The decompression at increased bandwidth and / or bit depth is enabled via a set of extension bits in addition to a base set of bits that represent a set of compressed audio frames. In the case of Opus format, the additional bandwidth and / or bit depth may be specified in a header. In these cases, for decoders that do not enable such decompression at the increased bandwidth, they may ignore the extension bits to preserve backward compatibility.

A power delivery system is described that enables instant 20V / 28V power delivery to sink devices by utilizing unique Configuration Channel (CC) resistor signatures to bypass standard power negotiation delays. The system may implement non-standard pull-down resistors (Rd) in sink devices and matching unique pull-up resistors (Rp) in source adapters to create CC voltages outside legacy USB PD specification ranges, instantly signaling full-power capability without traditional multi-step negotiations. Upon detecting such compatible unique signatures, the source may immediately apply a VBUS voltage of 20V or 28V at full current, eliminating the boot delays caused by standard USB PD negotiation processes. The system also avoids problematic sink standby (pSnkStdby) power consumption limitations that prevent dead battery boot scenarios. The system maintains backward compatibility through automatic fallback to standard USB PD negotiation when non-compliant devices are connected.

A determination that an application developed using the pre-update application development platform is associated with the second version of the function is made. Data associated with the application developed using the pre-update application development platform is then adjusted.

Compressing and re-securing blockchain data using a large codeword model (LCM) with deep learning. The LCM tokenizes the blockchain into sourceblocks, assigns unique codewords to each sourceblock, and processes the codewords through a deep learning core, enabling efficient compression, semantic understanding, and generation of blockchain data. In the event of a compromised block, the system re-encodes and rehashes the entire compressed chain, generating a new secured chain while preserving the original chain as metadata for backward compatibility. The LCM-based approach enhances security, efficiency, and resilience of blockchain networks, offering significant advantages over existing techniques.

A method and apparatus are provided for encoding device health information for remote attestation of health, where device health is represented by integer vectors, where zero values represent a state of health and non-zero values represent a state of unhealth.
