Abstract: The present invention relates to a method and an apparatus for encoding and decoding spectrum coefficients in the frequency domain. The spectrum encoding method may comprise the steps of: selecting an encoding type on the basis of bit allocation information of respective bands; performing zero encoding with respect to a zero band; and encoding information of selected significant frequency components with respect to respective non-zero bands. The spectrum encoding method enables encoding and decoding of spectrum coefficients which is adaptive to various bit-rates and various sub-band sizes. In addition, a spectrum can be encoded using a TCQ method at a fixed bit rate using a bit-rate control module in a codec that supports multiple rates. Encoding performance of the codec can be maximised by encoding high performance TCQ at a precise target bit rate.

Abstract: A method for generating a secure single-tap authentication user interface includes obtaining a screenshot of content from an application operating in an execution environment outside of a trusted execution environment, generating graphical elements of a single-tap authentication user interface, and generating a progress switching layer. Additionally, the method includes responsive to an authentication request, generating a composited display, the composited display comprising the screenshot of content from the application, the graphical elements of the single-tap authentication user interface, and the progress switching layer, passing the composited display from outside the trusted execution environment to the trusted execution environment and displaying, by the trusted execution environment, the composited display as part of a trusted user interface (TUI).
