Abstract
A module having access to a secure memory and an unsecure memory, the module configured to: read, from the secure memory via a secure channel, a decrypted decoded rendition of a base layer of a video signal, wherein the decrypted decoded rendition of the base layer has a first resolution; read, from the unsecure memory, a decoded rendition of an enhancement layer of the video signal, wherein decoded rendition of the enhancement layer has a second resolution, wherein the second resolution is higher than the first resolution; generate an upsampled decrypted decoded rendition of the base layer of the video signal by upsampling the decrypted decoded rendition of the base layer such that the upsampled decrypted decoded rendition of the base layer has the second resolution; apply the decoded rendition of the enhancement layer to the upsampled decrypted decoded rendition of the base layer to generate an output plane; output the output plane, via the secured channel, to the secure memory for storage in the secure memory, wherein the output plane is for use in outputting by an output module to a display.
