    CPC classification number: H05B47/175

    Abstract: In one aspect, an example method includes (i) causing a content-presentation device to output for presentation reference visual content; (ii) causing a lighting device to emit light in accordance with a lighting parameter, wherein initially the light emitted in accordance with the lighting parameter does not correspond to the reference visual content; (iii) receiving first input indicating an adjustment to the lighting parameter; (iv) responsive to receiving the first input, causing the lighting device to adjust the lighting parameter, thereby causing the lighting device to adjust the emitted light; (v) receiving second input indicating that the adjusted emitted light corresponds to the reference visual content; and (vi) responsive to receiving the second input, calibrating the lighting device at least by (i) causing storage of the adjusted lighting parameter and (ii) causing the lighting device to be configured to emit light in accordance with the stored lighting parameter.

    Abstract: A computing system that identifies a media stream that a media client is processing for presentation determines which frame format of the media stream the media client is processing for presentation. And the computing system uses that determined frame format as a basis to facilitate dynamic content modification. For instance, based on then determined frame format, the computing system could work to ensure that replacement or overlay content that the media client obtains to facilitate dynamic content modification of the media stream is of that determined frame format. Further or alternatively, based on the determined frame format, the computing system could work to ensure that the media client gets provisioned with reference fingerprints of that particular frame format of the media stream, for use to facilitate client-side fingerprint matching to confirm that the media stream continues to be identified media stream.

    Abstract: A computing system identifies a media stream being received by a client, based on fingerprint matching conducted with query fingerprints generated by the client at a frame rate. The computing system then causes the client to increase the frame rate, in order to facilitate establishment by the computing system of synchronous lock between true time within the media stream and client time according to an clock of the client. The computing system then uses the established synchronous lock as a basis to map a true-time point at which a content revision should be performed in the media stream to a client-time point at which the client should perform the content revision. And the computing system causes the client to perform the content revision at the determined client-time point.

    Abstract: Use of watermarking in a media stream as a trigger for carrying out a fingerprint-related action, such as starting to generate fingerprints of the media stream, increasing a rate of generation of fingerprints of the media stream, starting to report fingerprints of the media stream, requesting fingerprints, or engaging in a fingerprint comparison. In an implementation, a media client that is processing the media stream could detect the watermark in the media stream and could responsively carry out or cause to be carried out a fingerprint-related action. Or an entity in a media-distribution path along which the media stream flows to a media client could detect the watermark in the media stream and could responsively carry out or cause to be carried out a fingerprint-related action. Further, the watermark could be inserted into the media stream in the first place based on transport-stream carried metadata, among other possibilities.
