Abstract

The techniques and systems described herein are directed, in part, to interactions between one or more mobile device applications, mobile device modems (or communication hardware), networks, and other devices. In some embodiments, a device may record a video using a camera. The device may then increase a block size of a first portion of a frame in the video to create a modified video where the first portion includes a larger block size than a second portion of the frame of the modified video. The increased block size may reduce an amount of data used to transmit the modified video to another device using the network communication.

Claims

1. A method comprising:

monitoring a quality of a network communication between a transmitting device and a receiving device;

recording a video using a camera of the transmitting device;

increasing a block size of a first portion of a frame in the video based at least in part on the monitoring of the quality of the network communication to create a modified video where the first portion includes a larger block size than a second portion of the frame of the modified video, the increasing the block size to reduce an amount of data used to transmit the modified video to the receiving device using the network communication; and

transmitting the modified video from the transmitting device to the receiving device via the network communication.

2. The method as recited in claim 1, wherein the increasing a block size of the first portion of the frame includes:

performing facial recognition on the frame to identify an area of the frame that includes a face;

designating the area of the frame that includes the face as the second portion of the frame; and

designating a remaining area of the frame, other than the area of the frame that includes the face, as the first portion of the frame.

3. The method as recited in claim 1, wherein the increasing a block size of the first portion of the frame includes:

determining a width of a border to apply to the frame;

designating the area of the border as the first portion of the frame; and

designating a remaining area of the frame, other than the area of the border, as the second portion of the frame.

4. The method as recited in claim 3, wherein the determining the width of the border to apply to the frame includes determining a dynamic width that is inversely proportional to the amount of data used to transmit the modified video to the receiving device.

5. The method as recited in claim 3, wherein the determining the width of the border to apply to the frame includes:

identifying a face in the frame using facial recognition; and

selecting the width to prevent overlap of the border and the face identified in the frame.

6. The method as recited in claim 1, wherein the quality of the network communication includes at least one of delay, throughput, signal strength, packet loss, capacity, or interference.

7. The method as recited in claim 1, wherein the monitoring the quality of the network communication is performed by receiving a buffer fill level from a modem of the transmitting device that indicates the quality of the network communication.

8. The method as recited in claim 1, wherein the monitoring the quality of the network communication is performed by receiving a downlink indicator from the receiving device that indicates the quality of the network communication experienced by the receiving device.

9. The method as recited in claim 1, further comprising, after a predetermined event, decreasing the block size of the first portion to a block size of the second portion.

10. A device comprising:

a camera;

a transceiver to provide communications to a destination device over a network;

a processor; and

memory to store instructions that, when executed by the processor, cause the processor to perform acts including;

monitoring a quality of a network communication with the destination device;

recording a video using the camera;

increasing a block size of a first portion of a frame in the video based at least in part on the monitoring of the quality of the network communication to create a modified video where the first portion includes a larger block size than a second portion of the frame of the modified video; and

transmitting the modified video to the destination device using the transceiver.

11. The device as recited in claim 10, wherein the acts further comprise performing facial recognition of the frame to detect an area of the frame that includes a face, and assigning the area that includes the face as the second portion of the frame.

12. The device as recited in claim 11, wherein the acts further comprise replacing at least part of the first portion of the frame with a border.

13. The device as recited in claim 10, wherein the acts further comprise determining a size of a border to apply to the frame, wherein the first portion of the frame is based at least in part on the size of the border.

14. The device as recited in claim 13, wherein the first portion of the frame is the border, and wherein the border includes imagery that is different than imagery of the frame that is recorded by the camera.

15. The device as recited in claim 10, further comprising a modem, and wherein the monitoring the quality is performed by receiving a buffer fill level from the modem that indicates the quality of the network communication.

16. A method comprising:

recording a video using a camera;

performing facial recognition on a frame of the video to identify an area of the frame that includes a face;

increasing a block size of another area of the frame, other than the area of the frame that includes the face, to create a modified video; and

transmitting the modified video to a destination device via a network communication.

17. The method as recited in claim 16, further comprising monitoring a quality of a network communication between a transmitting device and the destination device, and wherein the increasing the block size is based at least in part on the quality of the network communication.

18. The method as recited in claim 17, wherein the monitoring the quality is performed by receiving a buffer fill level from a modem that indicates the quality of the network communication.

19. The method as recited in claim 17, wherein the monitoring the quality of the network communication is performed by receiving a downlink indicator from the destination device that indicates the quality of the network communication experienced by the destination device.

20. The method as recited in claim 16, wherein the increasing the block size of another area of the frame includes converting at least a portion of the another area into a border depicted within the frame.
