Patent ID: 8826346

Claim:
A method of operating an IP client device for presentation of video content to a viewer, wherein in a normal play mode the video content is received from a server in fragments each containing a plurality of video frames and the IP client device presents the video frames at a predetermined, uniform frame rate F frames per second, whereby a fragment containing N frames has a normal presentation duration of N/F seconds, the method comprising: receiving a trickplay request, transmitting the trickplay request to a server, receiving a manifest from the server, wherein the manifest references at least first and second consecutive video content fragments, the first fragment contains a sequence of N1 frames, where N1 is an integer greater than one, and the second fragment contains a sequence of N2 frames, where N2 is an integer greater than one, and the manifest defines a set of M1 frames of the first fragment, where M1 is an integer less than N1, and a set of M2 frames of the second fragment, where M2 is an integer less than N2, transmitting a request for said M1 frames and said M2 frames, receiving said M1 frames and said M2 frames, and presenting said M1 frames and said M2 frames consecutively at F frames per second, whereby the sequence of said M1 frames and said M2 frames has a presentation duration of (M1+M2)/F.
