Personal media broadcasting system with output buffer
First Claim
1. A device that transmits a media stream to a media player via a network, the device comprising:
- a processor configured to construct the media stream in a format suitable for transmission over the network, wherein the media stream is constructed from an audio/video signal using an adjustable encoding parameter having a value determined at least in part based upon an a then-current condition of the network so that the encoding of the media stream is adapted in real time based upon the then-current condition of the network; and
a network interface configured to transmit the media stream to a client over a network.

Abstract
A personal media broadcasting system enables video distribution over a computer network and allows a user to view and control media sources over a computer network from a remote location. A personal broadcaster receives an input from one or more types of media sources, digitizes and compresses the content, and streams the compressed media over a computer network to a media player running on any of a wide range of client devices for viewing the media. The system may allow the user to issue control commands (e.g., “channel up”) from the media player to the broadcaster, causing the source device to execute the commands. The broadcaster and the media player may employ several techniques for buffering, transmitting, and viewing the content to improve the user'"'"'s experience.

9. A placeshifting device comprising:
-
a receiver interface configured to receive audio/visual source content; a network interface configured to transmit data on a network; and a processor, wherein the processor is configured to construct a media stream suitable for transmission over the network from the received audio/video source content by encoding the source content using an encoding parameter selected at least in part based on a then-current condition of the network so that the encoding of the media stream is adapted in real time based upon the then-current condition of the network, wherein the placeshifting device is further configured to transmit the media stream via the network interface and to adapt the encoding of the audio/visual content by changing the encoding parameter as the then-current condition of the network changes during transmission of the media stream. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method for providing access to audio/visual content from a remotely located media client via a network, the method comprising:
-
constructing a media stream suitable for transmission over a network by encoding the audio/visual content using an encoding parameter selected at least in part based on a then-current condition of the network; sending the media stream from the transmit buffer to the remotely located media client over the network; and adapting the encoding of the audio/visual content by changing the encoding parameter as the condition of the network changes during streaming of the audio/visual content to the remotely located media client so that the encoding of the audio/visual content is adapted in real time based upon the then-current condition of the network. - View Dependent Claims (16, 17, 18, 19, 20)
