Abstract
In transmission systems using digital video broadcasting standards for handheld terminals data is transmitted in bursts. Due to the restricted computing time, buffering of one or more bursts is necessary. The invention provides a memory optimalization for consecutive burst support. Thereby, a cyclic or non-cyclic memory model for a memory unit (19) of the device (1) for receiving bursts is provided.
Claims10
A device for receiving bursts in a communications network, comprising:
- a receiving unit for receiving said bursts;
- and
- a memory unit, wherein said receiving unit is adapted to receive a first burst comprising multiprotocol encapsulation and forward error correction data and to send at least a part of said first burst to said memory unit, and is adapted to receive a second burst comprising multiprotocol encapsulation and forward error correction data and to send at least a part of said second burst to said memory unit, and wherein said memory unit is adapted to store said first burst in a first part and said second burst in a second part and to overwrite a part of said first burst to store said second burst after said first data is processed, wherein said memory unit is arranged so that the second part is sized based on a throughput for processing said data of said first burst.
A method for receiving burst in a communications network, which method comprises the steps of:
- receiving a first burst comprising multiprotocol encapsulation and forward error correction data;
- storing at least a part of said multiprotocol encapsulation data of said first burst and at least a part of said forward error correction data of said first burst;
- receiving a second burst comprising multiprotocol encapsulation and forward error correction data;
- storing a first part of said data of said second burst in a second memory part in addition to the data of said first burst stored in a first memory part, wherein said second memory part is sized according to a processing throughput of said data of said first burst;
- and
- overwriting a part of said data of said first burst in said first memory part with a second part of said data of said second burst, after said data of said first burst has been processed.
