Method and device for http streaming over unreliable transport protocol

A method of receiving by a second device data packets from a first device, the method comprising at the second device:

• receiving a data packet from the first device;
• retrieving from the received data packet an association table associating identifiers of a plurality of data packets, previously transmitted by the first device, and corresponding reliability information;
• determining, based on the association table, a data packet previously transmitted by first device, not correctly received by second device, a which is of reliable type;
• and
• requesting retransmition of the data packet.

A first device for transmitting data packets to a second device, the first device being configured for:

• sending a data packet to the second device;
• upon reception of a request for retransmitting the sent data packet is received from the second device, obtaining reliability information on whether the sent data packet is of reliable type or unreliable type;
• and
• if the data packet is of reliable type, then the data packet is resent to the second device;
• and
• if the data packet is of unreliable type, then a notification is sent to the second device for notifying the second device that the data packet is not to be resent.
