Patent ID: 8358301

Claim:
A method of producing a secondary depth map (D*) of a secondary video sequence (M*), wherein the secondary video sequence (M*) is derived from a primary video sequence (M) having a primary depth map (D) which comprises information which allows a suitable video rendering device to produce a three-dimensional rendering of the primary video sequence (M); wherein the secondary video sequence (M*) is available at a client (C) and wherein the primary depth map (D) is available at a server (S), which client and server are connected by a network (N), the method comprising the steps of: transmitting the primary depth map (D) from the server to the client, aligning, at the client, the primary depth map (D) with the secondary video sequence (M*) so as to produce alignment information (AI), and deriving, at the client, the secondary depth map (D*) from the primary depth map (D) using the alignment information (AI), wherein said secondary depth map (D*) comprises information which allows a suitable video rendering device to produce a three-dimensional rendering of the secondary video sequence (M*).
