A computer-implemented system (100) for presenting content to a subscriber comprises: a detection component (104) for detecting an inactive subscriber in a session of a website portal; a tracking component (114) for tracking interaction of the inactive subscriber with the session content; and an analysis component (202) for analysing subscriber browsing behaviour, extrapolating subscriber experience level based on the analysis, and suggesting content as session content, wherein the subscriber experience level is extrapolated by tracking how often a subscriber selects Help and other menu categories; and a content component (116) for obtaining and presenting new content targeted to the inactive subscriber during the session based on the tracked interaction of the inactive subscriber with the session content, wherein the session content is new content as part of the session content based on the subscriber experience level.

Apparatus and method for creating electronic programme guide

Apparatus and method for creating electronic programme guide

Invention relates to an apparatus and a method of creating an electronic programme guide from programme information stored in an electronic programme guide database for a plurality of channels. The apparatus for creating an electronic programme guide from programme information stored in an electronic programme guide database for a plurality of channels comprises a control unit, a display unit, a time selection unit comprising a user input interface, a programme information search unit and a determining device. The control unit further includes a displayed information updating unit. An electronic programme guide displays elements relating to programmes accessible on a plurality of channels at a given moment in time. When the given time changes, the electronic programme guide updates elements corresponding to channels on which a programme which is accessible at a new time is different from a programme accessible at the previous time.

Arranging sub-track fragments for streaming video data

Arranging sub-track fragments for streaming video data

Invention relates to means of storing and transporting encoded video data. The method includes assembling encoded video data into a video file fragment comprising sub-track fragments, which comprise a plurality of hierarchically related encoded video images of the encoded video data, arranged continuously in the decoding order within a corresponding sub-track fragment, wherein the hierarchically related encoded video images each correspond to a common hierarchical layer; outputting data; receiving a request in accordance with a streaming protocol which specifies the sub-track fragment. In the method, the request comprises a hypertext transfer protocol (HTTP) partial GET request which specifies a byte range corresponding to the sub-track fragment; outputting the hierarchically encoded video images of the sub-track fragment.

Projector

Projector

Projector includes a lamp (41) of a light source, an illumination control unit (74) which is configured to power the lamp in order to turn on the lamp of the light source, a cooling unit (6) which is configured to transmit a fluid coolant in order to cool the lamp of the light source and an activation control unit (763). The activation control unit (763) is configured to control operation of the cooling unit in a predefined period from the turning on the lamp of the light source. The activation control unit controls at least one of the duration of said predefined period and the limited intensity of flow of the fluid coolant per unit time, transmitted from the cooling unit during said predefined period, based on operating history of the lamp of the light source.

Method and apparatus for controlling device

Method and apparatus for controlling device

Registered device is identified from the screen input using the camera, the user input is taken for the identified device, and the control command corresponding to the input is transmitted to the identified device.

Device of image generation and camera system

Device of image generation and camera system

Invention relates to an image generation device, such as a CMOS image sensor, and a camera system. The result is achieved by the fact that the image generation device includes: a block of pixel matrix acting as a block of light reception, which includes devices of photoelectric conversion, and in which multiple pixels that release electric signals, when photons drop, are arranged in the form of a matrix; a block of a sensitive circuit, in which multiple sensitive circuits, which receive electric signals from pixels and perform binary detection in respect to the fact whether photons have or have not dropped onto pixels with the specified period of time, are arranged in the form of a matrix; and a block of a circuit of detection result integration, having a function of integration of multiple results of sensitive circuits detection for appropriate pixels or for each group of pixels, in which the block of detection result integration releases the number of fallen photons to the block of light reception, by means of photon count, for integration of multiple detection results in multiple pixels.

Video quality assessment technology

Video quality assessment technology

Method comprises phases, during which video bit stream containing a sequence of image frames is received, the error occurrence is determined in the display frame segment, time distribution and spatial distribution of the named error is identified by means of the motion vector information and internal prediction relating a segment, affected by the error, the quality of video bit stream is assessed on the basis of the named error distribution.
