Abstract:
A method of operating an IP client device for presentation of video content to a viewer includes the step of transmitting a trickplay request to a server. The client device receives from the server a manifest that references at least first and second consecutive video content fragments. The first fragment contains a sequence of N1 frames and the second fragment contains a sequence of N2 frames, and defines a set of M1 frames of the first fragment, where M1 is less than N1, and a set of M2 frames of the second fragment, where M2 is less than N2. The client device transmits a request for the M1 frames and the M2 frames and receives the M1 frames and the M2 frames. The client device presents the M1 frames and the M2 frames consecutively at the uniform, predetermined frame rate. The sequence of the M1 frames and the M2 frames has a presentation duration of (M1+M2)/F.
