Techniques are disclosed herein that provide a TV receiver that supports a set of existing iTV standards and proprietary iTV implementations. Further, the TV receiver can be extended to support additional iTV standards and proprietary iTV implementations. A digital television data stream is received and processed by a client. The digital television data stream is analyzed to determine which interactive television format is present. A registry of interactive television virtual machines is searched to determine whether a virtual machine is registered for the interactive television format. Each of the interactive television virtual machines is adapted for one of the interactive television formats. If a virtual machine that matches the interactive television format is found, it is loaded and hosted. Hosting the virtual includes providing services to the virtual machine through common application programming interfaces (APIs) machine includes. The common APIs may be used by any virtual machine that is loaded.

In one aspect, a method includes identifying an upcoming content-modification opportunity on a channel, where the upcoming content-modification opportunity relates to a modifiable content-segment transmitted by a content-distribution system on the channel, and where the modifiable content-segment includes an overlay content portion and a non-overlay content portion. The method also includes responsive to identifying the upcoming content-modification opportunity on the channel, identifying a content-presentation device tuned to the channel. The method also includes determining location data associated with the overlay content portion. The method also includes transmitting, to the identified content-presentation device, the determined location data to facilitate the content-presentation device performing a content-modification operation in connection with the identified upcoming content-modification opportunity on the channel, where performing the content-modification operation involves replacing only the non-overlay content portion with supplemental content.

The present technology relates to an information processing apparatus, mobile terminal, information processing method, program, and information processing system that can make it possible to easily link information output by a certain device to information output by another device. An information processing apparatus according to one aspect of the present technology includes: a reception control unit for allowing receiving a content containing first address information specifying a source of provision of first information being information related to the content; an output control unit for allowing outputting the content; an acquisition unit for acquiring the first information from a server acting as the source of the provision of the first information based on the first address information; and a provision unit for providing, to a mobile terminal, second address information included in the first information, the second address information specifying a source of provision of second information being mobile terminal-specific information related to the content. The present technology can be applied to a device including a display.

Disclosed herein is a display apparatus and a control method thereof, and more particularly, to a technology configured to extract captions displayed on a display screen, convert the captions into voice, and output the voice. The display apparatus includes a display, a sound outputter configured to output sound, and a controller configured to select a caption data acquisition method based on the type of caption displayed on the display, configured to convert the caption data, which is obtained according to the selected caption data acquisition method, into voice data, and configured to allow the sound outputter to output a content of the displayed caption as voice based on the voice data that is converted.

Disclosed are a logical channel number parsing method and a logical channel number parsing device. The method includes: acquiring an operator which provides program signal, and searching channels in sequence according to preset frequency points; acquiring channel information of a current frequency point, and extracting logical channel number data from the channel information, when searching channels according to each of the frequency points; and parsing the logical channel number data according to a prestored logical channel number configuration table corresponding to the operator, to obtain each of attribute parameters comprised in the logical channel number data. The present disclosure simplifies the parsing operation of the logical channel number.

The invention relates to a television broadcast system comprising a number of television cameras (C1, C2); at least one production unit (12) which is configured to generate a series of production images from the camera images of the number of television cameras (C1, C2) and to issue said images as production signals (S3); a number of analysis modules (A1, A2) which are configured to analyse each individual camera image, to calculate camera-image metadata (M) and an associated camera-image hash value (H) for each camera image and to issue the camera-image metadata (M) and the camera-image hash value (H) for each camera image asynchronously; a synchronisation module (14) connected to the production unit (12) and the analysis modules (A1, A2) and configured to receive the production images from the production unit (12) as synchronously buffered images and to calculate, for each production image, an associated production image hash value (HR). The synchronisation module (14) is also configured to compare production image hash values (RH) and camera image hash values (H), to assign, on the basis of this comparison, the associated camera-image metadata (Mj) of a camera image as production-image metadata (MR) to a current production image (Ri), and to issue the production-image metadata (MR) as synchronously buffered images; a multiplication module (16) connected to the synchronisation module (14) and the production unit (12) and configured to receive the production-image metadata (MR) from the synchronisation module (14) as synchronously buffered images and to receive the production images from the production unit (12) as synchronously buffered images, the multiplication module also being configured: to compensate a time difference between a production image and the associated production-image metadata (MR); to change in the production image, on the basis of the production-image metadata (MR), at least one portion of the production image by means of an augmentation, thus producing an augmented production image; and to issue the augmented production image.

A method for gaze tracking is provided. One embodiment of the method for gaze tracking, comprising: presenting a content to a viewer via a playback device, tracking a gaze path of the viewer with a gaze tracker coupled to the playback device, selecting a viewer profile from a plurality of viewer profiles stored in a viewer profile database based on the gaze path of the viewer, and predicting a future gaze location of the viewer based on the viewer profile. Systems perform similar steps and non-transitory computer readable storage mediums each store one or more computer programs are also provided.

A method of predicting point cloud attribute coding includes receiving point cloud data comprising one or more candidate points and extracting one or more candidate attribute values for the one or more candidate points from the received point cloud data. The method further includes calculating a weighted median from the one or more extracted candidate attribute values and a weight factor, whereby the weight factor corresponds to a relative importance factor of a candidate vector associated with the extracted candidate attribute values. The method further includes assign one or more prediction indices corresponding to attribute data for video encoding to the candidate points in response to the calculation of the weighted median, wherein the prediction indices and processing the media content to encode the attribute data associated with the candidate points having the lowest prediction indices.
