An example apparatus to measure media exposure, the apparatus including memory, computer readable instructions, and processor circuitry to execute the computer readable instructions to obtain an image of streaming media presented by a media device, the media device separate from the processor circuitry, extract a video watermark from a chroma key of the obtained image, convert the video watermark into text formatted metadata, and transmit the text formatted metadate to a central facility. ## Claims ### Claim 1 An apparatus to measure media exposure, the apparatus comprising: a processor; and a non-transitory computer readable storage medium, having stored thereon program instructions that, upon execution by the processor, cause performance of a set of operations comprising: obtain an image of streaming media presented by a media device, the media device separate from the processor; extract a video watermark from a chroma key of the obtained image; convert the video watermark into text formatted metadata; and transmit the text formatted metadate to a central facility. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the media device is a television and the image is retrieved from a camera having a line of sight of a display of the media device. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the set of operations further comprising: trigger an extraction of the video watermark from the obtained image. ### Claim 4 (depends on 3) The apparatus of claim 3, wherein the extraction is triggered based on a timer reaching a threshold time limit. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the set of operations further comprising: obtain the image of the presented media via an image sensor. ### Claim 6 An apparatus to measure media exposure, the apparatus comprising: means for obtaining an image of streaming media presented by a media device, the media device separate from the means for obtaining; means for extracting a video watermark from a chroma key of the obtained image; means for converting the video watermark into text formatted metadata; and means for transmitting the text formatted metadata to a central facility. ### Claim 7 (depends on 6) The apparatus of claim 6, wherein the media device is a television and the image is obtained from a camera having a line of sight of a display of the media device. ### Claim 8 (depends on 6) The apparatus of claim 6, further including means for triggering an extraction of the video watermark from the obtained image. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the extraction is triggered based on a timer reaching a threshold time limit. ### Claim 10 (depends on 6) The apparatus of claim 6, wherein the means for obtaining the image is to obtain the image of the presented media via a means for sensing. ### Claim 11 An apparatus to measure media exposure, the apparatus comprising: means for obtaining an image of streaming media presented by a media presenter separate from the means for obtaining; means for extracting video metadata from a chroma key of the obtained image; means for converting the video metadata into a text format; and means for transmitting the text formatted metadata to a central facility. ### Claim 12 (depends on 11) The apparatus as described in claim 11, wherein the media presenter is a display and the means for obtaining is to obtain a screenshot of the display. ### Claim 13 (depends on 11) The apparatus as described in claim 11, further including means for triggering the means for extracting to extract the video metadata from the obtained image. ### Claim 14 (depends on 11) The apparatus as described in claim 11, further including means for sensing, and wherein the means for obtaining is to obtain the image of the presented via the means for sensing. ### Claim 15 An apparatus to monitor media presented by a media device, the apparatus comprising: means for obtaining, with the means for obtaining separate from the media device presenting media to a user, media of the media device, the media including metadata embedded into a video stream of the media using a chroma key; means for extracting a watermark from the media displayed at the media device, the watermark including the chroma key; means for converting the watermark to an ID3 metadata format; and means for transmitting the ID3 formatted metadata to a central facility. ### Claim 16 (depends on 15) The apparatus as described in claim 15, wherein the means for transmitting is to transmit at least one of a user identifier or a device identifier to the central facility in association with the ID3 formatted metadata. ### Claim 17 (depends on 15) The apparatus as defined in claim 15, wherein the media includes pulse code modulation (PCM) audio data. ### Claim 18 (depends on 15) The apparatus as defined in claim 15, wherein the media device is television. ### Claim 19 (depends on 15) The apparatus as defined in claim 15, wherein the media device is coupled to a television to present the media on the television. ### Claim 20 (depends on 15) The apparatus as defined in claim 15, wherein the means for transmitting is to transmit the ID3 formatted metadata to the central facility via the Internet.
