Systems and methods for interfacing a white space device with a host device

摘要

Information is communicated from a host device to a receiving device via white space. A white space device is interfaced with the host device. The white space device has at least one port configured to communicatively interface with a host device to receive multimedia content from the host device. The white space device also optionally has a television band engine configured to encode a transport stream containing at least a portion of the multimedia content received from the host device. A transmitter is configured to transmit the transport stream via white space.

主权项

1. A white space device comprising:
at least one port for communicatively interfacing with a host device to receive multimedia data from the host device, the multimedia data being optionally displayed at the host device while being received via the at least one port, the multimedia data being received in response to a user input received at the host device; an encoder coupled with a multiplexer and physically encased in the white space device as a single physical unit comprising a short communication interface between the encoder and the at least one port, to encode at least a portion of the received multimedia data into a transport stream; a white space spectrum controller to determine available white space spectrum periodically while quieting a transmitter and to adjust a transmission channel dynamically to maintain the transport stream, based at least in part on the determination; and the transmitter to wirelessly output at least the transport stream encoded from the portion of the received multimedia data via white space.
