Abstract

A processor implemented method conserves bandwidth capacity by reducing the amount of bandwidth that is used in a communication channel between a content transmitting server and a content receiving client computer while streaming multimedia content. A content receiving client computer receives a multimedia streaming content from a content transmitting server. The multimedia streaming content has a video component and an audio component. In response to determining that a user of the content receiving client computer is no longer watching the video component of the multimedia streaming content, a processor generates and transmits an inattention alert to the content transmitting server. The inattention alert directs the content transmitting server to stream only the audio component of a remaining portion of the multimedia streaming content to the content receiving client computer.

Claims

1. A processor implemented method of conserving bandwidth capacity in a communication channel between a content transmitting server and a content receiving client computer while streaming multimedia content, the computer implemented method comprising:

receiving, by a content receiving client computer, a multimedia streaming content from a content transmitting server, wherein the multimedia streaming content has a video component and an audio component;

displaying the multimedia streaming content on a video display; and

in response to determining that a user of the content receiving client computer is no longer watching the video component of the multimedia streaming content, a processor generating and transmitting an inattention alert to the content transmitting server, wherein the inattention alert directs the content transmitting server to stream only the audio component of a remaining portion of the multimedia streaming content to the content receiving client computer.

2. The processor implemented method of claim 1, further comprising:

determining that the user is no longer watching the video component by detecting that the user has minimized a streaming content window on which the multimedia streaming content was being displayed on the video display.

3. The processor implemented method of claim 2, further comprising:

in response to determining that the user is once again watching the streaming content window, transmitting an attention alert from the content receiving client computer to the content transmitting server, wherein the attention alert directs the content transmitting server to transmit a further remaining portion of the multimedia streaming content with both the video component and the audio component to the content receiving client computer, and wherein the user is determined to once again be watching the streaming content window in response to the streaming content window being maximized on the video display.

4. The processor implemented method of claim 1, further comprising:

tracking a user'"'"'s eye movement with an eye tracking video camera; and

determining that the user is no longer watching the video component in response to the eye tracking video camera and a viewer attention detector determining, from the user'"'"'s eye movement, that the user has not watched the video display for more than a predetermined length of time.

5. The processor implemented method of claim 4, further comprising:

in response to the eye tracking video camera determining that the user is once again watching a video display, transmitting an attention alert to the content transmitting server, wherein the attention alert directs the content transmitting server to transmit a further remaining portion of the multimedia streaming content with both the video component and the audio component to the content receiving client computer.

6. The processor implemented method of claim 1, further comprising:

determining that the user is no longer watching the video component by detecting that the user has moved a first window, on which the multimedia streaming content is being displayed on the video display, behind a second window on the video display.

7. The processor implemented method of claim 6, further comprising:

in response to the user moving the first window back in front of the second window, generating and transmitting an attention alert to the content transmitting server, wherein the attention alert directs the content transmitting server to transmit a further remaining portion of the multimedia streaming content with both the video component and the audio component to the content receiving client computer.

8. A content transmitting server comprising:

a server link interface coupled to a communication link, wherein the communication link is communicatively coupled to a content receiving client computer;

a multimedia content buffer, wherein the multimedia content buffer holds a multimedia content that has a video component and an audio component; and

a multimedia-to-audio-only (MTAO) converter, wherein the MTAO converter converts the multimedia content into an audio-only content in response to receiving an inattention alert from the content receiving client computer, wherein the inattention alert is generated in response to a viewer attention detector at the content receiving client computer determining that a user of the content receiving client computer is not watching the video component of the multimedia content, and wherein only the audio-only content is transmitted from the content transmitting server to the content receiving client computer.

9. The content transmitting server of claim 8, further comprising:

an audio-only content buffer for buffering the audio-only content.

10. A content receiving client computer comprising:

a client link interface coupled to a communication link, wherein the communication link is communicatively coupled to a content transmitting server;

a viewer attention detector; and

an inattention alert generator, wherein the inattention alert generator generates an inattention alert for transmission to the content transmitting server in response to detecting that a user of the content receiving client computer is not watching a multimedia streaming content that is being streamed from the content transmitting server to a video display on the content receiving client computer, wherein the multimedia streaming content includes an audio component and a video component.

11. The content receiving client computer of claim 10, wherein the inattention alert directs the content transmitting server to transmit only the audio component from the multimedia streaming content.

12. The content receiving client computer of claim 10, further comprising:

a window minimizing detector, wherein the window minimizing detector determines that the user is no longer watching the video component by detecting that the user has minimized a streaming content window on which the multimedia streaming content is being displayed on the video display.

13. The content receiving client computer of claim 12, further comprising:

an attention alert generator, wherein the attention alert generator generates and transmits an attention alert to the content transmitting server in response to determining that the user is once again watching the streaming content window, wherein the user is determined to once again be watching the streaming content window in response to the streaming content window being maximized on the video display, and wherein the attention alert directs the content transmitting server to transmit a remaining portion of the multimedia streaming content with both the video component and the audio component to the content receiving client computer.

14. The content receiving client computer of claim 10, further comprising:

an eye tracking video camera for tracking a user'"'"'s eye movement, wherein the eye tracking video camera is logically coupled to the viewer attention detector, and wherein the viewer attention detector determines that the user is no longer watching the video component in response to the viewer attention detector determining, from the user'"'"'s eye movement tracked by the eye tracking video camera, that the user has not watched the video display for more than a predetermined length of time.

15. The content receiving client computer of claim 14, further comprising:

an attention alert generator, wherein the attention alert generator, in response to the viewer attention detector determining that the user is once again watching the video display, transmitting an attention alert to the content transmitting server, wherein the attention alert directs the content transmitting server to transmit a remaining portion of the multimedia streaming content with both the video component and the audio component to the content receiving client computer.

16. The content receiving client computer of claim 10, further comprising:

a window focus detector, wherein the window minimizing detector determines that the user is no longer watching the video component by detecting that the user has moved a first window, on which the multimedia streaming content is being displayed on the video display, behind a second window on the video display.

17. The content receiving client computer of claim 16, further comprising:

an attention alert generator, wherein the attention alert generator, in response to the user moving the first window back in front of the second window, generates and transmits an attention alert to the content transmitting server, wherein the attention alert directs the content transmitting server to transmit a remaining portion of the multimedia streaming content with both the video component and the audio component to the content receiving client computer.
