Rendering of an interactive lean-backward user interface on a television
Embodiments of the invention relate to user interfaces and systems and methods for generating a real-time “lean-back” user interface for use with a television or other display device and for reuse of encoded elements for forming a video frame of the user interface. An interactive session is established between a client device associated with a user's television and the platform for creating the user interface over a communication network, such as a cable television network. The user interface is automatically generated by the platform and is animated even without interactions by the user with an input device. The user interface includes a plurality of interactive animated assets. The animated assets are capable of changing over time (e.g. different images, full-motion video) and are also capable of being animated so as to change screen position, rotate, move etc. over time. A hash is maintained of cached encoded assets and cached elements that may be reused within a user session and between user sessions.

9. The method according to claim 1 , wherein the communications network does not include a quality of service.
10. The method according to claim 9 , wherein the method is performed substantially real-time.
11. The method according to claim 1 , further comprising:
causing a first interactive animated asset of the plurality of interactive animated assets to transition from an inactive state into an active state, including causing the first interactive animated asset to begin presentation of a full motion video sequence.
12. The method according to claim 11 , further comprising:
after a predetermined amount of time after causing the first interactive animated asset to transition from the inactive state to the active state:
causing the first interactive animated asset to transition from the active state into the inactive state; and
causing a second interactive animated asset to transition from an inactive state into the active state.
13. The method according to claim 12 , wherein:
causing the first interactive animated asset of the plurality of interactive animated assets to transition from the inactive state into the active state further includes causing an indicia of the activation to be displayed in association with the first interactive animated asset.
14. The method according to claim 12 , wherein causing the first interactive animated asset of the plurality of interactive animated assets to transition from the inactive state to the active state further includes causing an audio track associated with the first interactive animated asset to be transmitted with the sequence of encoded video frames.
15. The method according to claim 5 , wherein activation of an interactive animated asset of the plurality of interactive animated assets causes graphical portions of the user interface to be replaced with the full motion video.
16. The method according to claim 1 , wherein an interactive animated asset of the plurality of interactive animated assets in an inactive state is represented by a still image sized to fit within a tile.
