Abstract: The present invention relates to parallel treatment of DVB-H data bursts. It provides a method of reception of consecutive at least first and second data bursts and a data reception unit. The method comprise receiving a first data burst, processing the first data burst during a first period, and receiving a second data burst during a second time period, wherein the first and second time periods at least to some extent overlap in time. By using a first and a second memory for storing alternating data bursts, the data reception unit can be kept in an inactive less power consuming mode a longer time, thus saving energy as compared to prior art techniques.
