发明名称 Audio-visual data transmission over internet protocol at higher rates
摘要 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.

主权项 1. 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.
