Embodiments disclosed herein pertain to power conservation for electronic devices. According to one embodiment, power conservation can be achieved through adaptive frame rate control for a display associated with an electronic device. The frame rate is able to be controlled so as to adapt to a frame rate that is adequate for the display task. Since the display often times displays content that is not very dynamic, the frame rate in such situations can be controlled to use a reduced frame rate, which thereby reduces power consumption. However, when the display displays content that is substantially dynamic, the frame rate in such situations can be controlled to use an enhanced (or not reduced) frame rate, which ensures reasonable display quality.

A frequency-domain audio codec is provided with the ability to additionally support a certain transform length in a backward-compatible manner, by the following: the frequency-domain coefficients of a respective frame are transmitted in an interleaved manner irrespective of the signalization signaling for the frames as to which transform length actually applies, and additionally the frequency-domain coefficient extraction and the scale factor extraction operate independent from the signalization. By this measure, old-fashioned frequency-domain audio coders / decoders, insensitive for the signalization, would be able to nevertheless operate without faults and with reproducing a reasonable quality. Concurrently, frequency-domain audio coders / decoders able to support the additional transform length would offer even better quality despite the backward compatibility. As far as coding efficiency penalties due to the coding of the frequency domain coefficients in a manner transparent for older decoders are concerned, same are of comparatively minor nature due to the interleaving.
