Abstract

A method includes transmitting a low-resolution stream, buffering a high-resolution stream in a buffer memory, receiving a request for a high-resolution media item, retrieving the high-resolution media item from the buffer memory based on the frame numbers, and transmitting the high-resolution media item. The request includes one or more frame numbers based on the low-resolution stream.

First claim

What is claimed is:

1. A method comprising:
transmitting a low-resolution video stream;
buffering a high-resolution video stream in a buffer memory;
receiving a request for the high-resolution video stream, the request including beginning and ending frame numbers based on the low-resolution video stream;
retrieving the high-resolution video stream from the buffer memory via a synchronizer, wherein the synchronizer synchronizes the low-resolution video stream and the high-resolution video stream to a same relative time; and
transmitting the high-resolution video stream.

2. The method of claim 1 , further comprising:
receiving a device stream; and
encoding the device stream into the low-resolution video stream and the high-resolution video stream.

3. The method of claim 1 , wherein the low-resolution video stream is a medical imaging scan.

4. The method of claim 1 , wherein the beginning and ending frame numbers are determined based on an interest of a viewer in a part of the low-resolution video stream.

5. The method of claim 4 , further comprising:
detecting the interest of the viewer in a part of the low-resolution video stream based on the viewer pausing the low-resolution video stream.

6. The method of claim 4 , further comprising:
detecting the interest of the viewer in the part of the low-resolution video stream based on the viewer slowing the low-resolution video stream.

7. A system comprising:
one or more processors; and
a memory storing instructions that, when executed by the one or more processors, cause the system to:
transmit a low-resolution video stream;
buffer a high-resolution video stream in a buffer memory;
receive a request for the high-resolution video stream, the request including beginning and ending frame numbers based on the low-resolution video stream;
retrieve the high-resolution video stream from the buffer memory via a synchronizer, wherein the synchronizer synchronizes the low-resolution video stream and the high-resolution video stream to a same relative time; and
transmit the high-resolution video stream.

8. The system of claim 7 , the memory storing instructions that, when executed by the one or more processors, further cause the system to:
receive a device stream; and
encode the device stream into the low-resolution video stream and the high-resolution video stream.

9. The system of claim 7 , wherein the low-resolution video stream is a medical imaging scan.

10. The system of claim 7 , the memory storing instructions that, when executed by the one or more processors, further cause the system to halt transmission of the low-resolution video stream.

11. The system of claim 10 , the memory storing instructions that, when executed by the one or more processors, further cause the system to resume transmission of the low-resolution video stream.

12. The system of claim 7 , wherein the beginning and ending frame numbers are determined based on an interest of a viewer in a part of the low-resolution video stream.

13. The system of claim 12 , the memory storing instructions that, when executed by the one or more processors, further cause the system to:
detect the interest of the viewer in the part of the low-resolution video stream based on the viewer pausing the low-resolution video stream.

14. The system of claim 12 , the memory storing instructions that, when executed by the one or more processors, further cause the system to:
detect the interest of the viewer in the part of the low-resolution video stream based on the viewer slowing the low-resolution video stream.

15. A computer program product comprising a non-transitory computer useable medium having a computer-readable program, wherein the computer-readable program, when executed on a computer, causes the computer to:
receive a low-resolution video stream;
transmit a request for a high-resolution video stream, the request including beginning and ending frame numbers based on the low-resolution video stream; and
receive the high-resolution video stream via a synchronizer, wherein the synchronizer synchronizes the low-resolution video stream and the high-resolution video stream to a same relative time.

16. The computer program product of claim 15 , wherein the computer-readable program, when executed on a computer, further causes the computer to transmit a request to halt the low-resolution video stream.

17. The computer program product of claim 16 , wherein the computer-readable program, when executed on a computer, further causes the computer to transmit a request to resume the low-resolution video stream.

18. The computer program product of claim 17 , wherein the request to resume the low-resolution video stream is generated upon completion of receiving the high-resolution video stream.

19. The computer program product of claim 15 , wherein the beginning and ending frame numbers are determined based on an interest of a viewer in a part of the low-resolution video stream.

20. The computer program product of claim 19 , wherein the computer-readable program, when executed on a computer, further causes the computer to:
detect the interest of the viewer in the part of the low-resolution video stream based on the viewer pausing the low-resolution video stream.
