A method of display user movement in a computing device of a virtual reality system is disclosed. The method comprises generating a first image in a first-person perspective with a first-person control, simulating an avatar according to a first control signal received from a controller of the virtual reality system, and generating a second image including the avatar in the first-person perspective with a third-person control, wherein the first-person perspective indicates that a user sees images as if seen through the avatar's eyes, and a field of view of the avatar is controlled by the user, the first-person control indicates that a user's movement is displayed by a relative position between the avatar and a scene of the images, and the third-person control indicates that the user's movement is displayed by different locations of the avatar in the images.

Methods and apparatus provide for: recording a first sequence of video images output by a videogame, recording a sequence of depth buffer values for a depth buffer used by the videogame, recording a sequence of in-game virtual camera positions used to generate the video images, recording one or more in-game events and their respective in-game positions, generating a second sequence of video images encoding the depth buffer value sequence, and associating the in-game virtual camera position sequence, with at least one of the first and second sequence of video images. Methods and apparatus also provide for: obtaining a first video recording of a videogame playing session comprising a sequence of video images, obtaining a second video recording generated by encoding a depth buffer value sequence, obtaining data indicative of an in-game virtual camera position sequence that is associated with at least one of the obtained video recordings, obtaining data indicative of a statistically significant in-game event and an in-game event position, calculating a position within a current video image of the first video recording corresponding to the in-game event position, in dependence upon the associated in-game virtual camera position and decoded depth buffer values, and augmenting the current video image with a graphical representation of the statistically significant in-game event, responsive to the calculated position.

A method of generating a high-resolution image frame for a state of a video game within a 2D or 3D environment is disclosed. A low-resolution data map of a virtual camera frustum view of the 2D or 3D environment for the state is determined. The data map is of a data type. A high-resolution output data map of the data type is generated from the low-resolution data map. The generating of the high-resolution output data map includes training a neural network. The training includes associating a low-resolution data map of the data type with a high-resolution data map of the data type within the 2D or 3D environment. A high-resolution image of the frustum view is generated from the high-resolution output data map. The generated high-resolution image is displayed on a display device.
