A data processing system () for graphics processing, including a scene manager (). The scene manager () includes a scene loader () for receiving a description of 3 dimensional objects in a scene from a 3-dimensional modelling tool (). The description includes first 2-dimensional frame data. The scene manager () has a texture image modification unit () for receiving second 2-dimensional frame data from a 2-dimensional rendering engine (), and for replacing the first frame data by the second frame data. The scene manager () has an animation scheduler for scheduling and monitoring an animation of the scene. The system includes a display manager () operative to invoke the scene manager () to render output frames in a display buffer (), and a scene Tenderer () configured for applying the 2-dimensional frame data to the 3-dimensional objects to produce textured 3-dimensional objects in the display buffer () and outputting the textured objects in the animation. Related apparatus and methods are also described.

A system and method for video trick mode playback is described, the system and method including a user actuated control operative to slide () a playback position along a video file, the user actuated control including a rewind actuation, a forward actuation () and a default neutral actuation, a player device including a plurality of video file readers (-) operative to play the video frames at nominal frame rate disposed along the video file, around the playback position, the distance between the video file readers varying according to the sliding speed of the playback position, a trick play engine to control the sliding speed and direction of the playback position, the sliding speed and direction being functions of a user actuation and a trick play engine velocity, the position at which each one of the plurality of video file readers is disposed along the video file is updated to catch-up with the playback position when the playback position is not sliding forward at nominal frame rate according to predetermined rules.
