A method comprising generating, for primary content to be broadcasted for output on a primary content output device, rendering adaptation information configured for use in adapting the rendering of the primary content on a secondary content output device thereby providing an output of secondary content which is derived from the broadcasted primary content; wherein the primary content comprises at least a first media portion having a first temporal output characteristic; wherein the rendering adaptation information comprises temporal information configured for use in adjusting the rendering of the at least first media portion so as to enable generation of secondary content comprising at least a second media portion having a second temporal output characteristic that can differ from the first temporal output characteristic of the at least first media portion. Also disclosed is a method comprising receiving the above primary content and rendering adaption information in order to generate secondary content. Further disclosed is a method for generating secondary content, as above, wherein the rendering adaption information instead comprises two or more sets of spatial co-ordinates for identifying two or more media portions of the primary content for output as secondary content. Finally disclosed is a method for generating secondary content, as above, wherein the primary content has a dimension n and the rendering adaption information is configured to adjust the dimension n of the primary content to enable a dimension k of the secondary content, where k<n. |
