Abstract

A computer-implemented system and method for streaming video from a server to a client are described. For example, a method according to one embodiment comprises: receiving at the server a request for video content from the client; in response to the request, determining the hardware/software configuration of the client; generating and/or selecting a temporary decoder based on the hardware/software configuration of the client; transmitting the temporary decoder to the client, the client installing the temporary decoder; encoding and streaming the requested video content from the server to the client, the video content being encoded based on the capabilities of the temporary decoder, the video content being decoded by the temporary decoder and rendered on the client; detecting that the client has ended the session with the server; and in response to detecting that the client has ended the session, temporarily disabling and/or removing the temporary decoder from the client.

Claims

1. A computer-implemented method for streaming video from a server to a client comprising:

receiving at the server a request for video content from the client;

in response to the request, determining the hardware/software configuration of the client;

generating and/or selecting a temporary decoder based on the hardware/software configuration of the client;

transmitting the temporary decoder to the client, the client installing the temporary decoder;

encoding and streaming the requested video content from the server to the client, the video content being encoded based on the capabilities of the temporary decoder, the video content being decoded by the temporary decoder and rendered on the client;

detecting that the client has ended the session with the server; and

in response to detecting that the client has ended the session, temporarily disabling and/or removing the temporary decoder from the client.

2. The method as in claim 1 further comprising:

detecting one or more characteristics of the communication channel as the temporary decoder is being transmitted from the server to the client; and

encoding the requested video content on the server based on the detected characteristics of the communication channel.

3. The method as in claim 2 wherein one of the characteristics of the communication channel comprises the round-trip latency of the communication channel.

4. The method as in claim 2 wherein one of the characteristics of the communication channel comprises the data rate of the communication channel.

5. The method as in claim 2 wherein one of the characteristics of the communication channel comprises the reliability of the communication channel.

6. The method as in claim 5 wherein the reliability of the communication channel is characterized based on a percentage or lost packets or packets received with errors.

7. The method as in claim 6 wherein, in response to detecting a percentage of lost packets or packets received with errors below a first specified threshold value, then encoding the video content without error correction;

and in response to detecting a percentage of lost packets or packets received with errors above the first specified threshold value, then encoding the video content with error correction.

8. The method as in claim 7 wherein, in response to detecting a percentage of lost packets or packets received with errors above a second specified threshold value, then attempting to establish a different communication channel with the client.

9. The method as in claim 8 wherein the different communication channel is between the client and a different server.

10. The method as in claim 3 wherein, in response to detecting a round-trip latency above a specified threshold value, then attempting to establish a different communication channel with the client with a relatively lower round-trip latency.
