Advertisements in broadcast television programming are digitally replaced with different ads prior to viewing. Replacement can occur in time and/or place shifted content, and can be used to promote a particular advertisement that the viewer has not yet seen, thereby improving the reach of the ad without oversaturation. Data reporting by the playback devices is collected in a database of viewed ads. The information in the database can be used to refresh previously-viewed ads, to increase saturation of particular ads, to replace previously-broadcast but no longer relevant ads, or for other purposes as desired.

Methods and systems are described for condition mitigation. A computing device may display content. The computing device may determine that displaying and/or outputting the content may impact a person with a condition. The computing device may take an action to reduce an impact of the content on the person.

Methods, apparatus, systems and articles of manufacture are disclosed. An example apparatus includes a controller to cause a people meter to emit a prompt for input of audience identification information at a first time and determine a first audience count based on the input, an audio detector to determine a second audience count based on signatures generated from audio data captured in the media environment, and a comparator to cause the people meter to not emit the prompt for at least a first time period after the first time when the first audience count is equal to the second audience count.

Methods, apparatus, systems, and articles of manufacture to improve watermark detection in acoustic environments are disclosed. An example apparatus includes at least one memory, instructions in the apparatus, and processor circuitry to execute and/or instantiate the instructions to encode a first symbol in a media file at a first symbol position on a first encoding layer of a multilayered watermark, and encode a second symbol in the media file at a second symbol position on a second encoding layer of the multilayered watermark, the first encoding layer and the second encoding layer including a plurality of symbol positions, one or more of the plurality of the symbol positions on at least one of the first encoding layer or the second encoding layer to be empty.

Provided is a display device including a display unit, a storage unit configured to store information on a web page, a microphone configured to receive a user's voice command, a network interface unit configured to perform communication with a natural language processing (NLP) server, and a controller configured to transmit text data of the voice command to the NLP server, to receive intention analysis result information corresponding to the voice command from the NLP server, to select, as a final candidate address, one of a plurality of candidate addresses related to a search word included in the received intention analysis result information if the search word is not stored in the storage unit, and to access a website corresponding to the selected final candidate address.

A mobile device responds in real time to media content presented on a media device, such as a television. The mobile device captures temporal fragments of audio-video content on its microphone, camera, or both and generates corresponding audio-video query fingerprints. The query fingerprints are transmitted to a search server located remotely or used with a search function on the mobile device for content search and identification. Audio features are extracted and audio signal global onset detection is used for input audio frame alignment. Additional audio feature signatures are generated from local audio frame onsets, audio frame frequency domain entropy, and maximum change in the spectral coefficients. Video frames are analyzed to find a television screen in the frames, and a detected active television quadrilateral is used to generate video fingerprints to be combined with audio fingerprints for more reliable content identification.

A guide voice output control system includes a voice output control unit having a function of outputting a guide voice in response to a trigger and a function of executing interaction related processing having a reception stage for receiving voice, a recognition stage for recognizing voice, and an output stage for outputting voice based on a recognition result, in which the voice output control unit controls the output of the guide voice according to the processing stage of the interaction related processing when the trigger is generated during the execution of the processing, and dynamically controls the output of the guide voice according to whether or not the processing stage is a stage that does not affect the accuracy of voice recognition or listening difficulty of a user even if the guide voice is output.

An electronic device for providing graphic data based on a voice, and an operation method therefor are provided. The electronic device includes a display, and a processor, and the processor is configured to obtain at least one keyword from a voice signal related to a plurality of images, determine at least one graphic data corresponding to the at least one keyword, select at least one of the plurality of images, based on a point in time at which a voice corresponding to a keyword that corresponds to the determined graphic data is output, and perform control so as to apply the determined graphic data to the at least one selected image.

Disclosed are a user terminal and a control method therefor. A user terminal according to an aspect may include: an extraction unit that extracts original language information pertaining to each character on the basis of at least one among a video file and an audio file separately generated from a moving image file; a translation unit that generates translation information obtained by translating the original language information according to a selected language; and a control unit that provides at least one among the original language information and the translation information.

Methods, apparatus, systems and articles of manufacture are disclosed to identify user presence to a meter. An example apparatus includes memory, instructions, and at least one hardware processor to execute the instructions to at least: obtain presence information from a configuration device, the configuration device separate from the apparatus, the presence information indicating that user is present at the apparatus; verify the presence information matches user information, the user information stored in a memory of the apparatus; cause a confirmation prompt to be displayed on the configuration device, the confirmation prompt to indicate the presence information was obtained by the apparatus; and store the presence information in memory.
