White Paper Details
DVB-H Time Slicing & Power Consumption
The idea and intention to use Time Slices in DVB- is to reduce the power consumption of mobile DVB-H receivers.
Time Slices are slots where the relevant data is transmitted. This can be seen as bursts or time slotes as they are used in TDM telecommunication systems like GSM or IDSN.
The approach is:
You have a channel with a constant, maximum bandwidth, e.g. 15 MBit/s MPEG-2 Transport Stream capacity for all video streams and data You are going to radiate different video streams where each has a nominal bandwidth of e.g. 400 KBit/s You will save power by switching of the front end (DVB-H receiver) when your data is not available.
You are “informed” when to wake up your front end, when your next burst is expected.
