Abstract
A transmission and reception system includes a transmission apparatus for transmitting content and a reception apparatus for receiving the content. The transmission apparatus includes a coding section that codes the content into hierarchy codes and outputs coded data of a plurality of layers, a packet generation section that generates packets including the coded data and a timestamp and outputs packets from low-level information of the coded data, and a transmission section that transmits the packets. The reception system includes a reception section that receives the packets, a holding section that holds the packets, a writing control section that controls the writing of the packets, and a determination section that determines whether there is packet loss in the packets. When there is packet loss, the writing control section writes the packets received up to a time of packet loss based on a timestamp in the packets.
