A bi-directional communications interface includes a source multiplexer for connecting to a video source. The source multiplexer includes a source multiplexer input port for receiving an analog video signal from the video source, a source multiplexer output port for driving the video source with an upstream data signal, and a source multiplexer bi-directional port for coupling the analog video signal from the source multiplexer input port to the video cable and for coupling the upstream data signal from the video cable to the source multiplexer output port.

A method and apparatus for securely restricting the viewing of television programs. When a television program has been received along with rating data associated with a rating of the television program; length data associated with a length of the program, a microcomputer determines whether the rating data are higher than a predetermined viewing restricting level. If the rating data have been found higher, a muting circuit mutes the television program until it ends with reference to the television program length data, and the program corresponding to the rating data is outputted from a tuner.

In one of many possible embodiments, the present invention provides a host device that includes a positionable cooling element for dissipating thermal energy generated by a peripheral card inserted into the host device, a positioning mechanism coupled to the cooling element, and a latching mechanism coupled to the positioning mechanism. The movement of the latching mechanism from a first position to a second position causes the positioning mechanism to translate the cooling element towards the peripheral card.

A method of selecting a portion of a block of data for display based on characteristics of a display device. The method comprises several steps. In the first step, a block of Electronic Program Guide (EPG) data is received at a communication device adapted to process this data. Next, an input is received at the communication device regarding an appearance of the display device. The communication device can be a set-top box. The appearance of the display includes, but is not limited to, the resolution, the aspect ratio (AR), and the physical size of the display. Based on these inputs, the communication device next selects a portion, more or fewer columns or rows, of the block of EPG data to be displayed on the display device. The portion of the EPG data selected is formatted and communicated to the display device, e.g. television, for viewing by the user.

Correction of electron beam landing misalignment in a raster-type display is undertaken without using the usual set of coils, but rather by superimposing a landing misalignment correction signal on the already-existing velocity modulation (VM) coil or on another coil located at the junction of the electron beams in the neck of the display. The correction signal may be varied based on pressure, temperature, and ambient magnetic field as indicated by respective sensors to appropriately correct electron beam landing on phosphors the positions of which may be affected by variations in magnetic fields, temperature, and pressure.

A receiving apparatus and a receiving method arranged to reduce the delay time of tuning to and reception of a digital TV broadcast actually and apparently. A coefficient memory for storing coefficient data to be supplied to a channel equalizer of a front end section is provided. A control section generates equalizer coefficients supplied to the channel equalizer by using the equalizer coefficients in the coefficient memory, and updates the equalizer coefficients stored in the coefficient memory by substituting the generated equalizer coefficients for them. The control section supplies a predetermined video signal to a display section instead of a video output from a decoding section before the video output from the decoding section is obtained.

A picture receiving apparatus wherein a received video signal is converted into digital video data which is further compressed before being recorded on a minidisk set in a disk mounting unit along with caption information superimposed on the video signal and index information is recorded. A remote commander is used to select a desired item from index information displayed on a display screen. Pictures of the selected item are displayed on a child screen and caption information associated with the pictures is displayed in a caption display area.

A CPU is designed so as to put a demagnetizing circuit in an operative state in accordance with a result of detecting, among other quantities or events, the number of operations to turn on a power counted by a counter, the lapse of time under a predetermined condition measured by a timer since the pulling-out of an AC plug, the movement of the main body of a display device sensed by a sensor unit, an external magnetic field sensed by a sensor unit or a residual magnetism in a CRT itself sensed by a sensor unit. Instead of carrying out demagnetization each time the power is turned on, demagnetization is performed only under certain conditions when necessary, diminishing the problem of wasteful power consumption. On the top of that, the number of cases in which sound and picture vibration are generated due to a demagnetizing operation carried out right after the turning-on of the power is reduced, resulting in a product easy to handle by the user. In addition, the lives of components composing a demagnetizing circuit such as a positive thermistor can be prolonged.

An information terminal apparatus capable of ensuring enhanced operational facility and realizing easier maintenance of software required for a variety of services. The terminal apparatus includes an external information input port for receiving external software transmitted thereto by radio waves; a first memory for storing the software received by the external information input port; a first controller operated in accordance with the execution of the software stored in the first memory; a console for inputting predetermined data in conformity with the execution of the software; and a display for visually representing various kinds of information in conformity with the execution of the software. The software is obtained via a cable box for transferring a signal to or from the information terminal unit. The cable box includes an interface for transferring information to and from a host processor; a second memory for storing the software transmitted thereto from the host processor; and a second controller for controlling the signal transfer to or from the interface, the second memory and the information terminal unit.

A mobile settings control device (MSCD) presents a user interface (UI) enabling a user to establish display settings for a display associated with an audio video display device (AVDD) with which the MSCD communicates. Before and after adjustment screen shots may be presented full screen and toggled between on either the AVDD or MSCD, or split screens of before and after adjustment screen shots can be presented side by side on the AVDD or MSCD.
