A display apparatus includes: an obtainer that obtains HDR video data representing a luminance of each pixel by a code value; a converter that converts the HDR video data into HDR video using a first EOTF; a region extractor that extracts a first region including a pixel having a code value included in a first range of less than a first code value corresponding to a first point at which a slope of a tangent to the first EOTF is a predetermined slope and a second region including a pixel having a code value included in a second range of greater than or equal to the first code value; an adjuster that increases a sharpness gain of the first region relative to a sharpness gain of the second region in the HDR video data; and a display that displays the HDR video using adjusted data resulting from the adjustment.

Display apparatus and display method

A circuit module for a digital television receiver is formed by multi-layering a decoder LSI including a CPU and a decoder, a decoder layer substrate including a CA interface circuit, a demodulation function layer substrate including a demodulator, and an extension function layer substrate including a communication controller. The demodulation function layer substrate and the extension function layer substrate can be selectively multi-layered to the decoder layer substrate in response to a broadcasting system of a digital television signal or a type of a CA module.

Circuit module for use in digital television receiver for receiving digital television broadcasting wave signal

A module board has a configuration in which a first circuit board, a first composite sheet, a second circuit board, a second composite sheet, and a third circuit board are laminated in this order. Inspection terminals are arranged in a matrix shape in a predetermined region on an upper surface of the third circuit board. Electronic components are mounted on the first and second circuit boards. The inspection terminals are electrically connected to the electronic components mounted on the first and second circuit boards through vias and wiring patterns.

A transmitting party adds reproduction time information to each transport packet to form an extended transport packet, encapsulates the extended transport packet, adds capsule counter information, and transmits the capsule. A receiving party has a storage means, and transmits a re-send request including the capsule count information to the transmitting party when a packet loss occurs. At the receiving party, the re-sent data received overwrites data in its original storage region. At reproduction, the receiving party decodes the data after compensating for jitter referring to reproduction time information. Accordingly, a packet loss or jitter is compensated for at both transmitting and receiving parties in a communications network such as the Internet so as to prevent the occurrence of a decoding error at the receiving party.

Content receiver and content transmitter

Broadcast points in a broadcaster's sole region are turned into package information by processing the contents transmitted from a broadcaster, and the package information is stored in the receiver common information region of a television broadcast receiver, and thereby, it becomes possible even for a communication browser that is an application of the television broadcast receiver to refer to and use the information of broadcast points. It is possible by using a communication browser to receive a service provided in a home page of a company other than the broadcasting company.

Television receiver and digital broadcast system

A television broadcasting devicetransmits a television signal onto which control data for controlling a browser function of a television receiverhas been multiplexed. A television screen generating sectiongenerates a television screen based on the received television signal. A browser display instruction obtaining section, a URL obtaining section, and a display style information obtaining sectionextract the control data multiplexed onto the television signal. When a browser display instructionis received, a microcomputerreceives a contentcorresponding to a URLfrom a server, and generates a browser screen based thereon. A screen combining sectioncombines the browser screen with the television screen in accordance with display style informationreceived from the microcomputer. Thus, it is possible to display the browser screen in a combined form with the television screen in accordance with a display style designated by a broadcaster of the television signal.

A DTV module includes a CPU, a decoder, and a CA interface circuit. The decoder executes a decoding processing on a digital television signal inputted from a demodulator provided on a motherboard, so as to decode the digital television signal into a video signal and an audio signal, and outputs the video signal and audio signal. The CA interface circuit is connected to a CA module via a PC card socket, and executes input and output processings on signals communicated among the demodulator, CA module, decoder, and CPU. The CPU controls the CA interface circuit by switching types of the signals, so that a selected type of signal conforms to a type of the CA module, in response to a broadcasting system of a digital television signal or the type of the connected CA module.

An operation guarantee system includes a decoder circuit, a comparison circuit, a CPU circuit, a frequency adjustment circuit and a DQ adjustment circuit. The comparison circuit compares a test data signal input from the decoder circuit with an expected value data signal input from the exterior, and detects the presence or absence of an output error in the decoder circuit. The CPU circuit controls the frequency adjustment circuit and the DQ adjustment circuit to vary a frequency of a clock signal input to an external memory and a delay amount of the data signal. In addition, the CPU circuit acquires a result of detection of the comparison circuit under various conditions. Then, the CPU circuit determines an appropriate frequency of the clock signal input to the external memory based on a relationship between the various conditions and the presence or absence of the output error.

A name and a URL of a specific link destination are stored in a specific link destination information storing section. A microcomputer changes a process to be performed on a link destination depending on whether or not a link destination targeted for the process is a specific link destination. The specific link destination is highlighted when displaying link destinations as icons, and the specific link destination is displayed first when displaying a list of the link destinations. An access history about the specific link destination is stored in an access history storing section. An information server collects the access history from a television receiver and counts the number of accesses to the specific link destination. When the advertisement site is selected as the specific link destination, the number of accesses to the specific link destination is used as an index for indicating an advertising effect.

Television receiver and method for counting the number of accesses from the receiver

A television receiver (1) acquires numerical quantity information from program list information acquired from a television signal or the like, the acquired numerical quantity indicates the number of program-related information related to a television program and (2) displays the acquired numerical quantity information on a television display screen. When a user selects a television program whose program-related information is to be acquired, the television receiver acquires a URL of program-related information from an address server by utilizing the program identification code of the selected television program, acquires the program-related information from an information server by utilizing the acquired URL, and displays the acquired program-related information so as to be superimposed on a television picture.
