Video adaptation in conferencing using power or view indications
Conferencing applications run a variety of devices, including portable devices, such as smart phones, laptop computers, and tablet computers. A source device may be taking a high-resolution video to provide the video as a conference portion of a conference being viewed by a number of devices. The number of devices displaying the conference may only be displaying the conference portion as a thumbnail image, or other low-data image, or not be currently displaying the conference portion at all. The number of devices viewing the conference may then signal back to the source device to downgrade/terminate the capturing and/or transmission of the video. The source device then provides the video or other conference portion in a data-thrifty format more closely matching the conference portion as it is being displayed on the number of devices.
1. A communication device, comprising:
a network interface;
a video sensor that captures a video image;
a video controller that receives a throttling signal, via the network interface, from an endpoint receiving the video image;
wherein the throttling signal comprises a conference mode of a conference, the conference being provided by a host and the conference comprising the video image provided by the communication device and another conference portion provided by another device; and
wherein, in response to the throttling signal, the video controller adjusts an attribute of the capturing of the video image by the video sensor, the attribute effecting an encoding of the video image uploaded to the host via the network interface for receipt, as a portion of the conference, by a number of devices associated with a number of conference participants, the conference comprising the video image as adjusted.
2. The communication device of claim 1 , wherein the conference mode comprises indicia of an endpoint providing conference content.
3. The communication device of claim 1 , wherein the throttling signal comprises indicia of battery charge for a battery powering the endpoint.
4. The communication device of claim 1 , wherein:
the throttling signal is generated by a conference application executing on the endpoint and presenting, on the endpoint, a conference content comprising the video image and a conference component.
5. The communication device of claim 4 , wherein the conference mode comprises indicia of a communication type of the network interface being utilized by the endpoint receiving the conference content comprising the video image.
6. The communication device of claim 4 , wherein the conference mode comprises indicia of a display mode of the conference component.
7. The communication device of claim 6 , wherein the indicia of the display mode of the conference component, further comprises indicia of the conference component relative to the video image.
8. The communication device of claim 4 , wherein:
the communication device uploads, via the network interface, a conference comprising the conference content for display by the endpoint; and
in response to receiving the conference mode, the conference content is modified in accordance with indicia of the conference mode.
9. The communication device of claim 1 , wherein the attribute comprises at least one of frame rate, frame size, resolution, color, encoding method, and compression type.
10. A method, comprising:
receiving a conference content comprising a video portion received from a first conference device and a conference component from a third conference device;
broadcasting, via a network connection, a conference comprising the conference content to a second conference device;
receiving a conference mode indicia from the second conference device, wherein the conference mode indicia is associated with the conference content as displayed on the second conference device; and
signaling the first conference device to alter capturing of the video portion captured by a video sensor of the first conference device providing conference content in accordance with the conference mode indicia.
11. The method of claim 10 , further comprising:
determining that the conference mode indicia indicates the second conference device has been placed in a state, wherein the second conference device is displaying the conference content in a format requiring less bandwidth than a format of conference content received; and
wherein the step of signaling the first conference device to alter the conference content in accord with the conference mode indicia, further comprises signaling the first conference device to throttle bandwidth of the conference content.
12. The method of claim 10 , further comprising:
determining that the conference mode indicia indicates the second conference device is not displaying the conference content; and
wherein the step of broadcasting the conference further comprising, broadcasting the conference with a placeholder content in lieu of at least a portion of the conference content.
13. The method of claim 10 , further comprising:
determining that the conference mode indicia indicates the second conference device is not displaying the conference content; and
wherein the step of signaling the first conference device to alter the conference content in accord with the conference mode indicia, further comprises signaling the first conference device to discontinue providing the conference content.
14. The method of claim 10 , wherein the first conference device performs the step of broadcasting the conference.
15. A server, comprising:
a network interface configured to receive a conference portion comprising a first video from a first device and a conference component from a third device and transmit a conference, comprising the conference portion, to a second device; and
a processor, configured to receive by the second device and via the network interface, a first indicia of a presentation mode of the conference portion selected by a user of the second device, in response to the first indicia, transmit to the first device, via the network interface, a throttling signal to cause a video sensor of the first device to adjust capturing of an image captured thereby.
16. The server of claim 15 , wherein the first indicia of the presentation mode indicates an absence of presentation of the conference portion by the second device and the throttling signal indicates termination of the conference portion.
17. The server of claim 15 , wherein the first indicia of the presentation mode comprises a battery state indicia of the first device.
18. The method of claim 10 , wherein the third conference device, providing the conference component, and the second conference device, receiving the conference, are the same conference device.
19. The server of claim 15 wherein the third device, providing the conference component, and the second device, receiving the conference, are the same device.
