Patent ID: 8704947

Claim:
A portable wireless audio-video (AV) transmission device for pluggable connection to an AV source device, the AV source device including an AV source unit for generating an AV signal, and an output terminal for outputting the AV signal, the portable wireless AV transmission device comprising: a non-dedicated attachment selectively connectable to adaptively serve a plurality of different AV source devices, the non-dedicated attachment having a connector to be directly plugged and thereby electrically coupled without intervening transmission cable to the output terminal of the selected AV source device operating at a first video resolution, for receiving the AV signal; a video scaler unit housed within the non-dedicated attachment and electrically coupled to the connector, for upscaling a video signal of the AV signal received through the connector from the first video resolution to a second video resolution compatible with a playback device, the second video resolution being different from the first video resolution and outputting an upscaled AV signal including the upscaled video signal, the video scaler unit thereby maintaining AV signal upscaling operation external to the AV source and playback devices; and a wireless transmission unit housed within the non-dedicated attachment and electrically coupled to the video scaler unit, for wirelessly modulating and transmitting the upscaled AV signal that includes the upscaled video signal from the non-dedicated attachment in uncompressed format to the playback device.
