Abstract

Methods, systems, and apparatus, including medium-encoded computer program products for transmitting digital media streams. In one aspect, a computer-implemented method includes identifying and transmitting a sequence of frames in a digital video transmission, the sequence of frames comprising an initial frame and subsequent frames corresponding to the initial frame, the subsequent frames comprising data that incrementally updates the initial frame, and initiating a new transmission of the sequence of frames to a new device after sending one of the subsequent frames in the digital transmission, the initiating comprising generating information to cause the new device to inhibit presenting the new transmission until after frames between and including the initial frame and the one of the subsequent frames have been received by the new device, and transmitting, to the new device, the information and the frames between and including the initial frame and the one of the subsequent frames.

First claim

What is claimed is:

1. A computer-implemented method comprising:
identifying, by a server, a sequence of frames in a digital video, the sequence of frames comprising an initial frame and subsequent frames corresponding to the initial frame, the subsequent frames comprising data that incrementally updates the initial frame;
initiating a first transmission of the sequence of frames from the server to a first device;
receiving, from a second device, a request for a subsequent frame that forms part of the digital video;
sending the requested subsequent frame to the second device in response to the request; and
initiating a second transmission from the server to the second device after sending the requested subsequent frame to the second device, the initiating comprising
generating a message to cause the second device to inhibit presenting transmission of frames included within the sequence of frames until after the initial frame and frames between the initial frame and the requested subsequent frame have been received by the second device, and
transmitting, to the second device, the message, the initial frame, and the frames between the initial frame and the requested subsequent frame.

2. The method of claim 1 , wherein the initiating further comprises:
sending a second message to the second device to cause the second device to resume presenting, wherein the second message is sent after the frames between and including the initial frame and the requested subsequent frame are sent to the second device.

3. The method of claim 2 , further comprising sending the second message to the second device to resume presenting upon receiving a receipt message indicating receipt of the frames between and including the initial frame and the requested subsequent frame.

4. The method of claim 1 , wherein identifying the sequence of frames comprises retrieving the sequence of frames from a storage medium.

5. The method of claim 1 , wherein identifying the sequence of frames comprises receiving the sequence of frames from a publisher.

6. A non-transitory computer-readable medium, encoding a program operable to cause a data processing server to perform operations comprising:
identifying, by the data processing server, a sequence of frames in a digital video, the sequence of frames comprising an initial frame and subsequent frames corresponding to the initial frame, the subsequent frames comprising data that incrementally updates the initial frame;
initiating a first transmission of the sequence of frames from the data processing server to a first device;
receiving, from a second device, a request for a subsequent frame that forms part of the digital video, wherein the second device is separate from the data processing server;
sending the requested subsequent frame to the second device in response to the request; and
initiating a second transmission from the data processing server to the second device after sending the requested subsequent frame to the second device, the initiating comprising
generating a message to cause the second device to inhibit presenting transmission of frames included within the sequence of frames until after the initial frame and frames between the initial frame and the requested subsequent frame have been received by the second device, and
transmitting, to the second device, the message, the initial frame, and the frames between the initial frame and the requested subsequent frame.

7. The computer-readable medium of claim 6 , wherein the initiating further comprises:
sending a second message to the second device to cause the second device to resume presenting, wherein the second message is sent after the frames between and including the initial frame and the requested subsequent frame are sent to the second device.

8. The computer-readable medium of claim 7 , the operations further comprising sending the second message to the second device to resume presenting upon receiving a receipt message indicating receipt of the frames between and including the initial frame and the requested subsequent frame.

9. The computer-readable medium of claim 6 , wherein identifying the sequence of frames comprises retrieving the sequence of frames from a storage medium.

10. The computer-readable medium of claim 6 , wherein identifying the sequence of frames comprises receiving the sequence of frames from a publisher.

11. A system comprising:
a publisher configured to publish a digital video;
a server device including a processor; and
a non-transitory computer-readable medium encoding a streaming media engine configured to perform operations comprising:
identifying, by the server device, a sequence of frames in the digital video, the sequence of frames comprising an initial frame and subsequent frames corresponding to the initial frame, the subsequent frames comprising data that incrementally updates the initial frame;
initiating a first transmission of the sequence of frames from the server device to a first device;
receiving, from a second device, a request for a subsequent frame that forms part of the digital video;
sending the requested subsequent frame to the second device in response to the request; and
initiating a second transmission from the server device to the second device after sending the requested subsequent frame to the second device, wherein the initiating comprises
generating a message to cause the second device to inhibit presenting transmission of frames included within the sequence of frames until after the initial frame and frames between the initial frame and the requested subsequent frame have been received by the second device, and
transmitting, to the second device, the message, the initial frame, and the frames between the initial frame and the requested subsequent frame.

12. The system of claim 11 , wherein the initiating further comprises:
sending a second message to the second device to cause the second device to resume presenting, wherein the second message is sent after the frames between and including the initial frame and the requested subsequent frame are sent to the second device.

13. The system of claim 12 , the operations further comprising sending the second message to the second device to resume presenting upon receiving a receipt message indicating receipt of the frames between and including the initial frame and the requested subsequent frame.

14. The system of claim 11 , wherein identifying the sequence of frames further includes retrieving the sequence of frames from a storage medium.

15. The system of claim 11 , wherein identifying the sequence of frames further includes receiving the sequence of frames from the publisher.

16. The system of claim 11 , wherein the publisher is integrated with the streaming media engine.
