Abstract

Methods and apparatus to measure exposure to streaming media are described. An example method includes demultiplexing a closed captioning transport stream from a media stream, the media stream intercepted intermediate a media device and a display. Metadata is extracted from the closed captioning transport stream. At least one of the metadata or data based on the metadata is exported to a media measurement server.

Claims

1. A method of measuring exposure to streaming media, the method comprising:

intercepting, with a processor of a media monitor, a first media stream intermediate a media device and a display, the first media stream output by the media device based on a second media stream and a timed text track received at the media device from a service provider, the media monitor coupling the media device and the display, the timed text track including media-identifying metadata formatted in an ID3 format;

demultiplexing, with the processor, a closed captioning transport stream from the first media stream;

extracting metadata from the closed captioning transport stream, the metadata inserted into the closed captioning transport stream by the media device based on the timed text track;

determining whether the metadata is (1) the media-identifying metadata and is (2) formatted using the ID3 format; and

in response to determining that the metadata is (1) the media-identifying metadata and (2) is formatted using the ID3 format, exporting at least one of the metadata or data based on the metadata to a media measurement server.

2. The method as described in claim 1, further including timestamping at least one of the metadata or the data based on the metadata.

3. The method as described in claim 1, further including transmitting an identifier of at least one of the media device or the display to the media measurement system.

4. The method as described in claim 1, further including processing the metadata to form a media exposure metric.

5. The method as described in claim 1, wherein the media stream is a Moving Picture Experts Group version 2 (MPEG2) transport stream.

6. The method as described in claim 1, wherein the closed captioning transport stream is a digital television closed captioning (DTVcc) transport stream.

7. An apparatus to measure exposure to streaming media, the apparatus comprising:

a media interceptor to intercept a media stream intermediate a media device and a display, the media interceptor to couple the media device to the display, the media stream output by the media device based on media and a timed text track received from a service provider, the timed text track including media-identifying metadata formatted in an ID3 format;

a demultiplexer to demultiplex a closed captioning transport stream from the media stream;

a metadata extractor to extract metadata from the closed captioning transport stream, the metadata inserted into the closed captioning transport stream by the media device based on the timed text track; and

a transmitter to transmit the metadata to a media measurement server when the metadata is (1) the media-identifying metadata and (2) is formatted using the ID3 format.

8. The apparatus as described in claim 7, wherein the metadata extractor is to timestamp the metadata upon extraction of the metadata from the closed captioning transport stream.

9. The apparatus as described in claim 7, further including a metadata converter to convert the metadata into a format for transmission via the transmitter.

10. The apparatus as described in claim 9, wherein the format is a text format.

11. A tangible machine-readable storage medium comprising instructions which, when executed, cause processor of a media monitor to at least:

intercept a first media stream intermediate a media device and a display, the first media stream output by the media device based on a second media stream and a timed text track received at the media device from a service provider, the media monitor coupling the media device and the display, the timed text track including media-identifying metadata formatted in an ID3 format;

demultiplex a closed captioning transport stream from the first media stream;

extract metadata from the closed captioning transport stream, the metadata inserted into the closed captioning transport stream by the media device based on the timed text track;

determine whether the metadata is (1) the media-identifying metadata and is (2) formatted using the ID3 format; and

in response to determining that the metadata is (1) the media-identifying metadata and (2) is formatted using the ID3 format, export at least one of the metadata or data based on the metadata to a media measurement server.

12. The machine-readable medium as described in claim 11, wherein the instructions, when executed, further cause the processor to timestamp at least one of the metadata or the data based on the metadata.

13. The machine-readable medium as described in claim 11, wherein the instructions, when executed, further cause the processor to transmit an identifier of at least one of the media device or the display to the media measurement system.

14. The machine-readable medium as described in claim 11, wherein the instructions, when executed, further cause the processor to process the metadata to form a media exposure metric.

15. The machine-readable medium as described in claim 11, wherein the media stream is a Moving Picture Experts Group version 2 (MPEG2) transport stream.

16. The machine-readable medium as described in claim 11, wherein the closed captioning transport stream is a digital television closed captioning (DTVcc) transport stream.
