Abstract
A method of transmitting content to a content receiver and of receiving content from a content transmitted is provided. The method may include receiving, at a content transmitter, a content transmission request fragmenting a segmented content corresponding to the content transmission request into at least one frame, generating a header comprising a frame identifier for the at least one frame, and transmitting the at least one frame and the header to the content receiver.
Claims17
A method of transmitting content, the method comprising:
- receiving, at a content transmitter, a content transmission request;
- fragmenting a segmented content corresponding to the content transmission request into at least one frame;
- generating a header comprising a frame identifier for the at least one frame in a link adaptor layer set as an upper layer of a media access control (MAC) layer, the frame identifier being associated with a frame number of the at least one frame, a name of the content, and a segment number of a seament comprising the at least one frame, wherein the frame number is defined in the link adaptor layer and the name of the content and the segment number are defined in an upper layer of the link adaptor layer;
- and
- transmitting the at least one frame and the header to the content receiver,
- wherein the receiving of the content transmission request comprises receiving a transmission request of a lost frame at a random time in a lost frame request duration, the lost frame request duration being a time frame during which the lost frame is to be requested.
A method of receiving content from a content transmitter, the method comprising:
- transmitting a content transmission request to the content transmitter;
- and
- receiving at least one frame containing at least a portion of a segmented content corresponding to the content transmission request,
- wherein the at least one frame comprises a header with a frame identifier of the at least one frame, the header being generated in a link adaptor layer set as an upper layer of a media access control (MAC) layer,
- wherein the frame identifier is associated with a frame number of the at least one frame, a name of the content, and a segment number of a segment comprising the at least one frame,
- wherein the frame number is defined in the link adaptor layer and the name of the content and the segment number are defined in an upper layer of the link adaptor layer, and
- wherein the transmitting of the content transmission request comprise transmitting a transmission request of a lost frame at a random time in a lost frame request duration, the lost frame request duration being a time frame during which the lost frame is to be requested.
A content receiver for receiving content from a content transmitter, the content receiver comprising:
- a communicator configured:
- to transmit a content transmission request to the content transmitter, based on a content name, and
- to receive at least one frame containing at least a portion of a segmented content corresponding to the content transmission request, the content name being defined in a first layer;
- and
- a controller configured:
- to determine a lost frame that is not received from the content transmitter, and
- to control the communicator to transmit a lost frame retransmission request based on a plurality of information defined in the first layer to request retransmission of the lost frame in a second layer, the second layer being a lower layer of the first layer and being a link adaptor layer set as an upper layer of a media access control (MAC) layer,
- wherein the plurality of information is associated with a frame number of the at least one frame, a name of the content, and a segment number of a segment comprising the at least one frame wherein the frame number is defined in the second layer and the name of the content and the segment number are defined in the first layer, and
- wherein the communicator is further configured to transmit a transmission request of a lost frame at a random time in a lost frame request duration, the lost frame request duration being a time frame during which the lost frame is to be requested.
