US 2024/0040259 A1 · SYSTEMS AND METHODS FOR FREE-VIEW VIDEO STREAMING

Abstract

The disclosure relates to methods, apparatuses, and systems of providing livestream services involving multiple camera angles. A video streaming system may provide a client with a data stream that allows for viewing the video streaming from any of the multiple cameras at the client's choosing. The video streaming system may first access image data from the multiple cameras. Image data from the multiple cameras taken at a single instance in time may be “stitched” together into a single array of image data to form an “image wall.” The image wall may be compressed to be substantially smaller than the sum of their individual compressed images. A stream of image walls may be generated and transmitted to a client device. Metadata including mapping information enables the client to locate a chosen camera angle to view and switch to any camera angle viewing of the same video stream at the client's choosing.

Claims20

Dependent claims

A system for providing video streaming services, the system comprising:

a memory configured to store image data from a plurality of cameras, the image data comprising an image from each of the plurality of cameras recorded at a same instance in time;
a processor coupled to the memory;
and
an output interface coupled to the processor;
wherein the processor is configured to:
access the image data from the memory;
generate an image wall by combining each image from the plurality of cameras recorded at the same instance in time into an array of image data, wherein each of the images is positioned beside at least one other image within the image wall;
compress the image wall;
and
generate metadata associated with the image wall, the metadata comprising a mapping that ties, for each image within the image wall, a location of said image within the image wall to a camera among the plurality of cameras that recorded said image;
and
wherein the output interface is configured to transmit the compressed image wall and the associated metadata to a client device.

A system for viewing a video stream associated with a plurality of camera angles, the system comprising:

a memory configured to:
store a stream of image walls, wherein each image wall comprises image data recorded at a same instance in time from the plurality of camera angles;
and
store metadata associated with the stream of image walls, the metadata comprising a mapping that ties, for each image within an image wall of the stream of image walls, a location of said image within the image wall to a camera angle among the plurality of camera angles that recorded said image;
and
a processor coupled to the memory;
wherein the processor is configured to:
access the stream of image walls;
decompress each image wall among the stream of image walls;
access a user-selected camera angle;
locate, within the stream of image walls, a stream of images associated with the user-selected camera angle by utilizing the mapping within the stored metadata;
and
cause display of the stream of images associated with the user-selected camera angle.
