Presentation of content on a display device is adaptively modified based on the apparent size of a content area in which the content is presented. A distance between the first user and the display device is determined, as well as an actual size of the content area in which the content is being presented. Based on the distance and the actual size of the content area, an apparent size of the content area is calculated, and presentation of the content is modified based on the apparent size of the content area.

A method for playing multimedia data in an electronic device includes A method for playing multimedia data in an electronic device, the method comprising: receiving a request for transmitting a file including multimedia data to a second device; identifying sample playback data that is a portion of multimedia data; transmitting the identified sample playback data; and transmitting the multimedia data of the file to the second device after transmitting the sample playback data. An electronic device includes a radio frequency unit configured to transmit or receive a signal, and a processor configured to receive a sample playback data that is a part of the multimedia data of a file via the radio frequency unit, and play the received sample playback data of the multimedia data while receiving the file from the external device.

The present invention provides a digital video broadcasting-terrestrial (DVB-T) system and modulation method thereof. The system comprises a transmission module and a receiving module. The transmission module modulates a video signal to a DVB-T signal. The receiving module receives the DVB-T signal via a transmission line and demodulates the DVB-T signal to the video signal, and at the same time, monitoring the signal-to-noise ratio (SNR) or bit error rate (BER), and quantizes them to a reference data. The receiving module transmits the reference data to the transmission module through the same transmission line. The system can determine a control parameter according to the reference data to set the modulation parameter of the DVB-T signal.

The present invention relates to a display system for displaying an image on a display comprising: (a) said display system includes physical information related to a physical resolution of physical pixels for said displaying said image on said display; (b) said display system includes logical information related to an application graphics plane that includes a graphics plane resolution of logical pixels; (c) said display system selects said image to be displayed within said application graphics plane on said display from a set of available images based upon said logical information related to said graphics plane resolution of logical pixels.

A wireless device supporting Wi-Fi Direct service includes: a display; a communication unit; and a controller configured to cause: transmitting resolution information including a plurality of resolutions that are supported by the wireless device to a second wireless device; receiving an entire image including a first image and a second image from the second wireless device if a resolution of the first image is not one of the plurality of resolutions; displaying the first image by removing the second image from the received entire image when the entire image is received; and receiving the first image from the second wireless device without the second image if the resolution of the first image is included in the resolution information, the second image being an image that is added to the first image such that a resolution of the received entire image corresponds to one of the plurality of resolutions.

A method of connecting a mobile device to a common display associated with a display computer controlling the common display, including, for each mobile device downloading a display application onto the mobile device, selecting the display computer for the common display in the display application, connecting the mobile device to the display computer, selecting, on the mobile device, what is to be displayed on the common display, and sending a data stream of the selection to the display computer to be displayed in a window on the common display corresponding to the mobile device.

Methods and systems are disclosed that allow a user to efficiently navigate media selections in an interactive media guidance application and easily identify media for viewing. The disclosed methods and systems provide an environment wherein video assets are displayed according to a user preference on a mosaic page with multiple cells. A subset of the assets appropriate for display in a particular cell is determined based on the user preference. Relevance scores of the assets meeting the user preference are computed, and the asset having the greatest relevance for the user is selected and displayed the corresponding cell. The relevance scores can be computed based on the user's historic viewing habits, user interaction with a media guidance application, or on specific user input.

An information processing apparatus in communication with a video output apparatus via a wireless communication network includes a screen display unit outputting a screen on a display apparatus; a screen data acquisition unit acquiring screen data of the screen; a screen data transmission unit transmitting the screen data to the video output apparatus via the wireless communication network; an apparatus capability acquisition unit inquiring about apparatus capability of the video output apparatus and acquiring the apparatus capability from the video output apparatus; and one of a resolution change unit changing a screen resolution of the screen, which is output by the screen display unit, in accordance with the apparatus capability or an acquisition range change unit changing a range, which is acquired by the screen data acquisition unit, in accordance with the apparatus capability into a part of the screen data.

A digital broadcast receiving apparatus capable of executing a function with a higher added value is provided. A broadcast receiving apparatus configured to receive contents includes: a receiving unit configured to receive the contents; an interface through which the contents received by the receiving unit are outputted; and a control unit configured to control an output state of the contents from the interface. The control unit is configured to determine an output state of the contents from the interface in accordance with a combination of control information indicating a copy control state of the contents, control information for specifying whether protection is required or not when the contents are to be outputted, information indicating resolution of video of the contents, and information indicating transmission characteristics of the video of the contents, which are received by the receiving unit together with the contents.
