Abstract

An example device for retrieving media data, the device comprising: a memory configured to store scene data and image data; and one or more processors implemented in circuitry and configured to: receive data for a bitstream indicating that the bitstream includes one or more overlay images, the overlay images comprising either a single static image to be presented with scene data that remains constant while being presented frame-by-frame with frames of the scene data or an image sequence that repeats with a regular periodicity while being presented frame-by-frame with the frames of the scene data; receive the one or more overlay images from the bitstream; receive the scene data including one or more scene images; and present the scene images and the overlay images.

Claims23

Dependent claims

A method of retrieving media data, the method comprising:

receiving, for a Real-time Transport Protocol (RTP) bitstream, session description protocol (SDP) data including an SDP image attribute indicating that the RTP bitstream includes one or more sets of one or more images to be overlayed over scene data of the RTP bitstream, the SDP image attribute including:
a payload type syntax element that corresponds to a set of one or more images of the one or more sets of one or more images to be overlayed over the scene data and carried within the RTP bitstream;
and
an item count syntax element corresponding to the payload type syntax element, the item count syntax element representing a number of images included in the set of one or more images to be overlayed over the scene data;
receiving the one or more images from the RTP bitstream;
receiving the scene data including one or more frames;
and
presenting the one or more frames and the one or more images, wherein the one or more images are overlayed over the one or more frames of the scene data.
