Abstract
A transmission device includes a data controller to output one or more data frames; a encoder to generate one or more encoded data packets for a first data frame among the one or more data frames; and a transmission controller to determine a transmission time point of each of the one or more encoded data packets, and transmit the one or more encoded data packets to a reception device at the determined transmission time point corresponding to each of the one or more encoded data packets.
Claims15
A transmission device, comprising:
- a data controller configured to output a plurality of data frames;
- an encoder configured to generate a first plurality of encoded data packets and a second plurality of encoded data packets for the plurality of data frames by applying each data frame of the plurality of data frames to a preset encoding matrix;
- and
- a transmission controller configured to
- determine transmission time points of each encoded data packet of the first plurality of encoded data packets and second plurality of encoded data packets, and
- transmit the first plurality of encoded data packets and second plurality of encoded data packets to a reception device at the determined transmission time points,
- wherein
- each encoded data packet of the first plurality of encoded data packets is generated based on each corresponding data frame among the plurality of data frames, and
- each encoded data packet of the second plurality of encoded data packets is generated based on at least two data frames among the plurality of data frames, and
- wherein the transmission controller is configured to determine
- each transmission time point of each encoded data packet of the first plurality of encoded data packets as a first time point when the encoder generates the each encoded data packet of the first plurality of encoded data packets and
- each transmission time point of each encoded data packet of the second plurality of encoded data packets as a second time point after a preset delay time from when the encoder generates the each encoded data packet of the second plurality of encoded data packets.
