Inheritance in a tiered signal quality hierarchy

Computer readable hardware storage having instructions stored thereon, the instructions, when carried out by a processing device, causing the processing device to perform operations of:

• receiving a first set of reconstruction data to reconstruct the signal at a first level of quality, the first set of reconstruction data including a symbol specifying an attribute setting of a parent element in the rendition of the signal at the first level of quality;
• dividing the parent element into multiple sub-elements to reconstruct the signal at a second level of quality, the second level of quality higher than the first level of quality;
• and
• utilizing the attribute setting of the parent element as specified by the symbol and the rendition of the signal at the first level of quality to produce a default attribute setting for a respective sub-element in the multiple sub-elements unless a second set of reconstruction data to reconstruct the signal at the second level of quality specifies a different attribute setting for the respective sub-element.

A computer system comprising:

• a processor;
• a memory unit that stores instructions associated with an application executed by the processor;
• and
• an interconnect coupling the processor and the memory unit, enabling the computer system to execute the application and perform operations of:
• receiving a first set of reconstruction data to reconstruct the signal at a first level of quality, the first set of reconstruction data including a symbol specifying an attribute setting of a parent element in the rendition of the signal at the first level of quality;
• dividing the parent element into multiple sub-elements to reconstruct the signal at a second level of quality, the second level of quality higher than the first level of quality;
• and
• utilizing the attribute setting of the parent element as specified by the symbol as a default attribute setting for a respective sub-element in the multiple sub-elements until a second set of reconstruction data to reconstruct the signal at the second level of quality specifies a different attribute setting for the respective sub-element.
