Systems and methods for controlling the encoding of a media stream
First Claim

1. A method of encoding a media stream provided from an encoding system to a remotely-located media player, the method comprising:
- encoding the media stream at the encoding system according to at least one encoding parameter;
gathering data about a transmit buffer that receives the encoded media stream within the encoding system;
processing the gathered data about the transmit buffer to determine an estimate of network capacity and a calculated encoder rate, wherein the estimate of network capacity is based upon a rate of data leaving the transmit buffer;
adjusting the at least one encoding parameter during subsequent encoding as a function of at least one of the estimate of network capacity and the calculated encoder rate; and
transmitting the encoded media stream to the remotely-located media player.

Abstract
Systems and methods are described for providing a media stream transmitted from an encoding system to a remotely-located media player. The media stream is encoded according to an encoding parameter. Data is gathered about a transmit buffer within the encoding system, and the gathered data is processed to arrive at an estimate of network capacity and a calculated encoder rate. The encoding parameter is adjusted during subsequent encoding in response to a change in at least one of the estimate of network capacity and the calculated encoder rate.

16. A system for encoding a media stream provided to a remotely-located media player, the system comprising:
-
a transmit buffer; means for encoding the media stream according to at least one encoding parameter and for providing the encoded media stream to the transmit buffer; means for controlling the system, wherein the controlling means is configured to gather data about the utilization of the transmit buffer, to process the gathered data to determine an estimate of network capacity based upon a rate that the transmit buffer empties and a calculated encoder rate based upon a rate that the transmit buffer fills, and to adjust the at least one encoding parameter in the encoding means during subsequent encoding as a function of at least one of the estimate of network capacity and the calculated encoder rate; and means for transmitting the encoded media stream to the remotely-located media player.

17. A media encoding system for providing a media stream to a remote player over a network, the media encoding system comprising:
-
a media encoding module configured to receiving an input signal and to encode the media stream according to at least one encoding parameter; a network interface configured to transmit the encoded media stream to the remote player over the network; a transmit buffer configured to be filled by the media encoding module and emptied by the network interface; and a control module configured to gather data about the transmit buffer, to process the gathered data determine an estimate of a network capacity based upon a rate that the transmit buffer empties and a calculated encoder rate based upon a rate that the transmit buffer fills, and to adjust the at least one encoding parameter during subsequent encoding as a function of at least one of the estimate of network capacity and the calculated encoder rate. - View Dependent Claims (18)
