Abstract: A computer-implemented method of video coding comprises receiving at least one frame of a video sequence of an interactive application interface associated with at least one asset displayable on the interface in response to a user action related to the interface. The method includes encoding the at least one frame. The method also includes transmitting the at least one asset and the encoded at least one frame to a remote device. The transmitting operation refers to performing the transmitting regardless of whether a request to display the at least one asset exists. The asset can be a non-persistent asset on the frame only while a user performs a continuous action or maintains a cursor at a specific place on the interface. The asset also can be a persistent asset on the frame in response to a first action and is removed from the display in response to a second action.
