Based at least in part on the distinct sets of encoded data, the signal processor decodes and reconstructs a corresponding rendition of signal for each set of the encoded data. The distinct sets of renditions of signal are then combined into a single rendition of reconstructed signal. ## Claims ### Claim 1 A method comprising: via computer processor hardware, performing operations of: retrieving a transient image signal component and a core image signal component from storage, the transient image signal component being encoded at a first set of multiple different bit rates, the transient image signal component being encoded independently of encoding the core image signal component, the encoded transient image signal component at the first set of multiple different bit rates supporting multiple levels of playback quality and the core image signal component being encoded at a second set of multiple different bit rates, the core image signal component being encoded independently of encoding the transient image signal component, the encoded core image signal component at the second set of multiple different bit rates supporting multiple levels of playback quality; combining the transient image signal component and the core image signal component together to generate a single data stream for transmission to a target recipient; transmitting, over a communication link, the single data stream to the target recipient;
