Abstract
A technique to switch high data rate content from higher frequency band transmission to lower frequency band transmission that uses Internet Protocol, without adding appreciable latency or jitter that may be manifested on a display.
Claims20
A method comprising:
- formatting data content by control of an audio/video protocol adaptation layer based upon characteristics of a first communication protocol, the formatted data content destined for transmission to a target device over a first frequency band using the first communication protocol and during a beacon interval, wherein the formatted data content is separated into a plurality of data chunks to provide gaps in the transmission to avoid overflow of a decoder buffer in the target device, the formatted data content including timing reference information to maintain synchronization of the data chunks, and wherein the first communication protocol is a non-Internet Protocol based communication protocol;
- reformatting a portion of the data content including a subset of the plurality of the data chunks, by control of the audio/video protocol adaptation layer and upon unavailability or interruption of transmission over the first frequency band using the first communication protocol, for transmission over a second frequency band using a second communication protocol, wherein the first frequency band is higher in frequency than the second frequency band;
- communicating with the target device to establish transmission specifications to manage transfer of the reformatted portion of the data content over the second frequency band and to maintain synchronization of the plurality of data chunks to avoid overflow of the decoder buffer in the target device, in accordance with the timing reference information, when the subset of the plurality of data chunks are transmitted over the second frequency band;
- and
- transmitting the portion of the data content over the second frequency band using the second communication protocol and the transmission specifications.

A method comprising:
- formatting data content into a first format based on a first communication protocol at a source device to transmit the data content during a beacon interval over a first frequency band using a directional transmission, wherein the data content is separated into a plurality of data chunks to provide transmission gaps to not overflow a buffer in a target device, and wherein the first communication protocol is a non-Internet Protocol based communication protocol;
- establishing first communication protocol parameters to service the data content so as to not overflow the buffer in the target device, the first communication protocol parameters including timing reference information relating to synchronization of the plurality of data chunks;
- transmitting a portion of the data content over a first communication link at the first frequency band to the target device;
- detecting that the first communication link to the target device is not present;
- formatting the data content based on a second communication protocol to transmit the data content over a second frequency band using a non-directional transmission, wherein the first frequency band is higher in frequency than the second frequency band;
- communicating with the target device to establish transmission specifications to manage transfer of the data content over the second frequency band and to maintain synchronization, between the source device and the target device, of the plurality of data chunks when transmitted over the second frequency band so as to not overflow the buffer in the target device;
- and
- transmitting the data content over a second communication link at the second frequency band using the second communication protocol.

An apparatus comprising:
- a transmitter to transmit outbound radio frequency (RF) signals;
- a receiver to receive inbound RF signals;
- and
- a processing module, including a processor and coupled to the transmitter and the receiver, to provide processing of data content specified by a communication protocol to:
- format the data content, based upon characteristics of a first communication protocol, the formatted data content destined for transmission to a target device over a first frequency band using the first communication protocol and during a beacon interval, wherein the formatted data content is separated into a plurality of data chunks to provide gaps in the transmission to avoid overflow of a decoder buffer in the target device, the formatted data content including timing reference information to maintain synchronization of the data chunks, and wherein the first communication protocol is a non-Internet Protocol based communication protocol;
- upon unavailability of transmission over the first frequency band using the first communication protocol, reformat the data content including a subset of the plurality of the data chunks for transmission over a second frequency band using a second communication protocol, wherein the first frequency band is higher in frequency than the second frequency band;
- communicate with the target device using a third communication protocol to establish transmission specifications to manage transfer of the reformatted data content over the second frequency band and to maintain synchronization of the plurality of data chunks to avoid overflow of the decoder buffer in the target device, in accordance with the timing reference information, when transmitted over the second frequency band;
- and
- transmit the data content over the second frequency band using the second communication protocol.
