Multimedia broadcast forwarding systems and methods

摘要

In various embodiments, communication apparatus and methods for providing robust communications are disclosed. For example, an exemplary communication apparatus for distributing media to one or more receiving apparatus may include receiving circuitry to receive a first wireless multimedia broadcast signal containing at least a first media stream, transmitting circuitry to wirelessly transmit one or more individual media streams simultaneously to the one or more receiving apparatus using one or more wireless transmit signals, and decision circuitry configured to control the transmitting circuitry to transmit the first media stream to at least one receiving apparatus using at least one wireless transmit signal type based on a forward-link data capacity of each wireless channel between the transmitting circuitry and each receiving apparatus.

主权项

1. A wireless communication device for distributing media to one or more receiving apparatus, comprising:
receiving circuitry to receive a first wireless multimedia broadcast signal containing individual media streams; extraction circuitry to extract the individual media streams including at least a first media stream from the received multimedia broadcast signal; transmitting circuitry to wirelessly transmit each of the individual media streams simultaneously to respective ones of a plurality of receiving apparatus via different wireless channels using different wireless signal protocols; decision circuitry to select a wireless signal protocol from the different wireless signal protocols based on variable wireless conditions local to the wireless communication device including a forward-link data capacity of each of the different wireless channels between the transmitting circuitry and each of the plurality of receiving apparatus, to control the transmitting circuitry to transmit the first media stream to at least one receiving apparatus by the selected wireless signal protocol, to determine a more advantageous one of the different wireless signal protocols for a switch of protocols based on information regarding existence and status of the different wireless channels using the different wireless signal protocols, and to switch from the selected wireless signal protocol to the more advantageous wireless signal protocol to transmit the first media stream from the transmitting circuitry to the at least one receiving apparatus in response to the more advantageous wireless signal protocol being determined; and handoff circuitry responsive to the decision circuitry to control the transmitting circuitry to switch protocols.
