Abstract: A broadcast receiving apparatus makes it possible to select a desired television program quickly by channel-surfing. The broadcast receiving apparatus outputs information of the received broadcast content as television program information of a channel for which the broadcast content is received, includes an operation detector that detects a channel that selects operation, an operation speed calculator that calculates a channel selecting operation speed from the detected channel selecting operation, a list item count determiner that determines, according to the calculated channel selecting operation speed, the number of channels for which the television program information is displayed, a channel determiner that determines channels to be listed so that the television program information is displayed for the determined number of channels, and a display that outputs the television program information of the determined channels to be listed.

Abstract: Provided is a broadcast receiving apparatus which makes it possible to select a desired television program quickly by channel-surfing.

Abstract: A method of driving a liquid crystal display device includes: branching original image data having an original data rate into branched plural-systems image data comprising plural systems having a converted data rate that is equal to either said original data rate or a half of said original data rate; supplying a source driver circuit with said branched plural-systems image data in synchronization with at least one clock signal having a clock frequency that is a quarter of said original data rate; and allowing said source driver circuit to further branch said branched plural-systems image data into gray-scale voltage signals. Circuitry for driving the liquid crystal display device may include: a timing controller; a plurality of data bus lines; and a plurality of source driver circuits for incorporating said image data in synchronization with said at least one clock signal and converting said image data into gray-scale voltage signals.

Abstract: To provide a reception device for receiving a broadcast wave, selecting any of a commercial stream and a program stream that are modulated in the broadcast wave, and outputting the selected stream. The reception device includes an acceptance unit which accepts a channel operation by a user, and a switch unit which, when the acceptance unit accepts the channel operation, selects the commercial stream before the program stream, as the stream to be output.

Abstract: A device control system is provided, in which a host device uploads optimal program code suitable for its own system environment from a target device for control. In the target device 2, a plurality of pieces of program code 231 through 23n used for different system environments and a header object 221 associated with the respective pieces of program code are stored in advance. The host device 1 obtains the header object 221 from the target device 2, and then parses the obtained header object 221 to determine program code 23x (x is one of 1 through n) optimal for its own system environment. The host device 1 then uploads the determined program code 23x from the target device 2 for interpretation, thereby controlling the target device 2.

Abstract: An active-matrix addressing LCD device prevents the formation of unwanted horizontal stripes without decreasing the luminance. The polarity of a data voltage applied to each of the pixels by way of a corresponding one of the data lines and a corresponding one of the TFTs is inverted in every set of two or more horizontal synchronizing periods (e.g., the 2-H dot or line inversion method). The source driver has a resetting means for resetting the data voltages outputted by the source driver circuit in the blanking period of each of the horizontal synchronizing periods. The source driver may have a polarity-inverting means for inverting the polarity of the data voltages outputted by the source driver circuit in the blanking period of each of the horizontal synchronizing periods. The data voltages in each of the horizontal synchronizing periods can be uniform in their rising states.
