Overlay rendering of user interface onto source video
First Claim
1. A method of providing an interactive user interface for generating a blended output that includes the interactive user interface and one or more supplemental images, the method comprising:
- at a server remote from a client device;
transmitting a video stream that includes an interactive user interface towards the client device using a first data communications channel configured to communicate video content;
receiving a command that relates to a user input received through the interactive user interface;
generating an updated interactive user interface in accordance with the command;
in accordance with a determination that the client device is not capable of overlaying the updated interactive user interface and one or more supplemental images;
determining, at the server, a state of a decoder at the client device by retrieving one or more frames buffered on the server to obtain a state that corresponds to a frame corresponding to the command related to the user input; and
blending the updated interactive user interface and the one or more supplemental images determined based on the state of the decoder at the client device to generate a blended output frame with the one or more supplemental images over the updated interactive user interface, wherein each supplemental image of the one or more supplemental images is associated with a corresponding transparency coefficient and the blending is performed according to the transparency coefficient for each supplemental image of the one or more supplemental images; and
transmitting the blended output frame toward the client device for display on a display device.

Abstract
A method of generating a blended output including an interactive user interface and one or more supplemental images. At a client device, a video stream containing an interactive user interface is received from a server using a first data communications channel configured to communicate video content and a command is transmitted to the server that relates to a user input received through the interactive user interface. In response to the transmitting, an updated user interface is received using the first data communications channel, and one or more supplemental images are received using a second data communications channel. Each supplemental image is associated with a corresponding transparency coefficient. The updated user interface and the one or more supplemental images are blended according to the transparency coefficient for each supplemental image to generate a blended output and the blended output is transmitted toward the display device for display thereon.
