Abstract:
1. A device comprising: an encoder to encode a data stream comprising a sequence of digital values; and a power management module to indicate an amount of available power, said power management module being designed to indicate a sequence of amounts of available power at corresponding time instances, wherein said encoder is designed to receive said sequence of amounts and to select an encoding technique to encode a corresponding subset of said sequence of digital values in response to said receiving said sequence of amounts, and to select a first encoding technique to encode said data stream if said amount is above a threshold and a second encoding technique otherwise, further wherein said sequence of digital values represent a sequence of image frames and said encoder comprises a first block designed to estimate motion between successive image frames at a first resolution and a second block designed to estimate motion between successive image frames at a second resolution, which respectively perform said first encoding technique and said second encoding technique.
