Abstract: An information communication terminal device adapted for an IPTV service that delivers program data from one of a plurality of delivery servers via a communication network includes a channel selection unit, a program data acquisition unit, and a display control unit. The channel selection unit selects a channel number according to channel allocation which defines allocation of channels corresponding to broadcasting regions. The program data acquisition unit requests a specific delivery server to deliver program data according to link information associated with the selected channel number and acquires the program data delivered from the specific delivery server in response to the request. The display control unit performs control such that program content is displayed on a screen based on the received program data. In response to a first operation by a user with respect to the screen, the channel selection unit determines a channel number of a first switching destination according to the channel allocation.

Abstract: An information communication terminal device adapted for an IPTV service, which delivers program data from one of a plurality of delivery servers via a communication network, includes: a program selection unit, a program data acquisition unit, and a display control unit. The program selection unit selects a program according to EPG information in which program scheduling is defined by a plurality of channels and a plurality of delivery time slots along a time axis, the program being selected based on the channels and the delivery time slots. The program data acquisition unit requests delivery of program data of the program to a specific delivery server according to link information and a program identification code, both of which are associated with the selected program, and acquires the program data delivered from the specific delivery server in response to the request. The display control unit performs control such that program content is displayed on a screen based on the received program data.

Abstract: An external device may recognize, in the case of including a communication unit that executes communication via a communication path made up of a pair of differential transmission paths included in a transmission path, information relating to the communication unit thereof. A disk recorder transmits function information indicating that a communication unit (high-speed data line I/F 213) configured to execute communication with an external device via a communication path made up of a reserve line and an HPD line of an HDMI cable to a television receiver via a CEC line that is a control data line of the HDMI cable. The television receiver receives function information, whereby whether or not the disk recorder is an eHDMI-compatible device can be determined, and in the case of an eHDMI-compatible device, a compatible transmission format (application) can be recognized.

Abstract: An AV system composed of an HD recorder and a display unit uses a communication interface of the HDMI. An HDMI source of the HD recorder transmits image data (image signal) in the form of differential signals to an HDMI sink of the display unit through three TMDS channels. The HDMI source inserts content identification information for the identification of the type of a content of image data to be transmitted into an AVI InfoFrame packet placed in a blanking period. A control section of the display unit controls operation of a display processing section which carries out a process for displaying for the image data based on the content identification information received by the HDMI sink and a display section for displaying an image.

Abstract: An internal focus lens includes sequentially from an object side, a first lens group having a positive refractive power; a second lens group having a negative refractive power; and a third lens group having a positive refractive power. The first lens group includes an anti-vibration lens formed by a negative lens that is moved in an orthogonal direction with respect to an optical axis to correct image blur consequent to optical system vibration, and further includes an aperture stop disposed farther on an image side of the first lens group than the anti-vibration lens. The second lens group is moved along the optical axis to perform focusing.
