Patent ID: 8019917

Claim:
An audio/video (AV) capture device, comprising: a signal source, capturing an external image to generate a first input video signal; an AV processor, receiving and compressing the first input video signal generated by the signal source to generate a second input video signal; a first video streaming adapter (VSA), receiving the first input video signal generated by the signal source and adding a first payload header onto the first input video signal to generate a first video streaming; a second video streaming adapter (VSA), receiving the second input video signal generated by the AV processor and adding a second payload header onto the second input video signal to generate a second video streaming; a micro controller, generating a command to the first and the second VSA; and a transmission unit coupled to the first VSA and the second VSA, transmitting the first video streaming generated by the first VSA and the second video streaming generated by the second VSA to an external device by time division duplex; wherein the first VSA and the second VSA communicate with each other through an interlock mechanism, to avoid the first VSA and the second VSA concurrently outputting the first video streaming and the second video streaming to the transmission unit.
