Abstract

Systems, apparatuses and methods may include a source device that generates a scene change notification in response to a movement of a camera, modifies an encoding scheme associated with the video content captured by the camera in response to the scene change notification, identifies a full-frame difference threshold, wherein scene analysis information includes frame difference data, and compares the frame difference data to an intermediate threshold that is less than the full-frame difference threshold, wherein the scene change notification is generated when the frame difference data exceeds the intermediate threshold. A sink device may obtain transport quality data associated with video content, modify an output parameter of a display based on the transport quality data, determine a view perspective of a still image containing a plurality of image slices, retrieve only a subset of the plurality of image slices based on the view perspective and decode the retrieved subset.

Claims

1. A sink device comprising:

a display to present video content;

a substrate;

logic coupled to the substrate, wherein the logic is implemented in one or more of configurable logic or fixed-functionality hardware logic, the logic to;

obtain transport quality data associated with the video content, and

modify an output parameter of the display based on the transport quality data; and

a network controller, wherein the logic is to;

determine a first view perspective of a still image that provides a panoramic view of a scene, the still image containing a plurality of image slices and being stitched together from a plurality of crowd-sourced high-resolution images, wherein each of the plurality of image slices include metadata respectively indicating how each of the plurality of image slices maps to the still image and how zooming is to be conducted on each of the plurality of image slices,

retrieve, via the network controller, only a subset of the plurality of image slices based on the first view perspective, and

decode the retrieved subset to obtain a decoded first subset.

2. The sink device of claim 1, wherein the transport quality data is to include one or more of frame delay data, frame drop data or frame error data.

3. The sink device of claim 1, wherein the output parameter is to include one or more of a refresh rate or a decode quality level.

4. The sink device of claim 1, wherein the logic is to determine a second view perspective of the still image, and wherein the second view perspective is to occur after the first view perspective.

5. The sink device of claim 4, wherein if the second view perspective is completely within a field of view of the first view perspective, the logic is to render the decoded first subset based on the second view perspective.

6. The sink device of claim 4, wherein if the second view perspective is not completely within a field of view of the first view perspective, the logic is to:

retrieve an additional subset of the plurality of image slices based on the second view perspective,

decode the additional subset to obtain a decoded second subset, and

render the decoded second subset based on the second view perspective.

7. The sink device of claim 1, wherein the logic is to render the decoded first subset based on the first view perspective.

8. The sink device of claim 1, wherein the first view perspective is to include a zoom level and a pan position.
