Abstract

In one aspect, an example method includes (i) capturing, by a computing system, via a camera of the computing system, video content; (ii) encoding, by the computing system, the captured video content to generate a video stream; and (iii) while generating the video stream: (a) making, by the computing system, a determination that each condition in a condition set is satisfied, wherein the condition set includes a condition relating to a change in a data rate of the video stream; and (b) responsive to making the determination, outputting, by the computing system, via a user interface of the computing system, an indication that the computing system is unsteady.

First claim

What is claimed is:

1. A method comprising:
receiving, by a computing system, from an end-user device, a video stream generated by the end-user device, the video stream representing video content captured by a camera of the end-user device, wherein the video stream has a data rate, wherein the data rate is an amount of data of the video stream that is streamed per unit of time; and
while receiving the video stream:
making, by the computing system, a determination that each condition in a condition set is satisfied, wherein the condition set includes a condition relating to a change in the data rate of the video stream with respect to at least one threshold, and wherein the at least one threshold is selected by the computing system based on one or more encoding parameters being used by the end-user device to generate the video stream; and
responsive to making the determination, causing, by the computing system, the end-user device to output, via a user interface of the end-user device, an indication that the end-user device is unsteady.

2. The method of claim 1 , wherein the one or more encoding parameters includes an encoding standard being used by the end-user device to generate the video stream.

3. The method of claim 1 , wherein the computing system is a content system of a video production system (VPS), wherein the VPS is configured to integrate the video stream into a video program for production.

4. The method of claim 1 , wherein causing the end-user device to output the indication comprises transmitting, to the end-user device, an instruction to output the indication, the method further comprising:
while the end-user device is generating the video stream:
receiving, by the end-user device, from the computing system, the instruction; and
responsive to receiving the instruction, outputting, by the end-user device, via the user interface of the end-user device, the indication.

5. The method of claim 1 , wherein the indication is a visual indication, and wherein causing the end-user device to output the indication comprises transmitting, to the end-user device, a message including the visual indication, the method further comprising:
while the end-user device is generating the video stream:
receiving, by the end-user device, from the computing system, the message including the visual indication; and
responsive to receiving the message including the visual indication, displaying, by the end-user device, via the user interface of the end-user device, the message.

6. The method of claim 1 , wherein the at least one threshold includes a threshold amount, and
wherein the condition is that the change in the data rate of the video stream is at least the threshold amount.

7. The method of claim 1 , wherein the generated video stream includes a first portion and a second portion that is different from the first portion, the method further comprising:
while generating the video stream, determining, by the computing system, a first data rate of the first portion and a second data rate of the second portion,
wherein the at least one threshold includes a first threshold data rate and a second threshold data rate, and
wherein the condition is that the determined first data rate is less than the first threshold data rate and the determined second data rate is greater than the second threshold data rate.

8. The method of claim 7 , wherein each of the first and second portions of the generated video stream include a common portion of the generated video stream.

9. A non-transitory computer-readable medium having stored thereon program instructions that upon execution by a processor, cause performance of a set of acts comprising:
receiving, by a computing system, from an end-user device, a video stream generated by the end-user device, the video stream representing video content captured by a camera of the end-user device, wherein the video stream has a data rate, wherein the data rate is an amount of data of the video stream that is streamed per unit of time; and
while receiving the video stream:
making, by the computing system, a determination that each condition in condition set is satisfied, wherein the condition set includes a condition relating to a change in the data rate of the video stream with respect to at least one threshold, wherein the at least one threshold is selected by the computing system based on one or more encoding parameters being used by the end-user device to generate the video stream; and
responsive to making the determination, causing, by the computing system, the end-user device to output, via a user interface of the end-user device, an indication that the end-user device is unsteady.

10. The non-transitory computer-readable medium of claim 9 , wherein the one or more encoding parameters includes an encoding standard being used by the end-user device to generate the video stream.

11. The non-transitory computer-readable medium of claim 9 , wherein the computing system is a content system of a video production system (VPS), wherein the VPS is configured to integrate the video stream into a video program for production.

12. The non-transitory computer-readable medium of claim 9 , wherein causing the end-user device to output the indication comprises transmitting, to the end-user device, an instruction to output the indication, the set of acts further comprising:
while the end-user device is generating the video stream:
receiving, by the end-user device, from the computing system, the instruction; and
responsive to receiving the instruction, outputting, by the end-user device, via the user interface of the end-user device, the indication.

13. The non-transitory computer-readable medium of claim 9 , wherein the indication is a visual indication, and wherein causing the end-user device to output the indication comprises transmitting, to the end-user device, a message including the visual indication, the set of acts further comprising:
while the end-user device is generating the video stream:
receiving, by the end-user device, from the computing system, the message including the visual indication; and
responsive to receiving the message including the visual indication, displaying, by the end-user device, via the user interface of the end-user device, the message.

14. The non-transitory computer-readable medium of claim 9 , wherein the at least one threshold includes a threshold amount, and
wherein the condition is that the change in the data rate of the video stream is at least the threshold amount.

15. The non-transitory computer-readable medium of claim 9 , wherein the generated video stream includes a first portion and a second portion that is different from the first portion, the set of acts further comprising:
while generating the video stream, determining, by the computing system, a first data rate of the first portion and a second data rate of the second portion,
