摘要：
A solution for delivery of audiovisual content to a receiver device is provided. At the transmitter side, a transmission buffer is constituted, while offering fast channel change and fast trick modes at the receiver side. At least one GoP, starting with a first I-frame is sought in the content that is to be transmitted. The timing references of the data in the at least one GoP that is prepared for delivery to a receiver device are modified so that the data is decoded by the receiver at a slowed-down rate for a given duration. This creates a lag between reading of data in by the transmitter and decoding of data by the receiver. The lag is used by the transmitter to fill the transmission buffer, while the receiver does not have to wait for the transmission buffer to be filled to start decoding.
