摘要： PROBLEM TO BE SOLVED: To easily access desired information among many bookmarks even when the resolution of a screen is small by displaying connection destinations from this size in the decreasing order of priority. SOLUTION: A display unit 10 has the 'contents' of a bookmark arranged on a circular table 60. The table 60 is divided into 8 genres of 'weather' 68, 'news' 69, 'travel' 70, etc. Then contents are displayed as icons behind the icons of the genres. For example, the icon 63 of 'homepage 1' is displayed in pattern representing its feature. This arrangement order is determined according to the degree of user's 'preference'. Namely, the icon on the most front side has the largest degree of 'preference', which decreases toward rearer ones. Here, a three-dimensional display accompanied by a perspective converting process is made.

摘要： PROBLEM TO BE SOLVED: To easily and accurately recognize the broadcasting condition of a desired program by extracting a character code related to a specified character code from program information and displaying a character corresponding to the character code in the prescribed area of a program chart. SOLUTION: A data extraction part 109 extracts program information from data information outputted from a signal separation part 102, decodes it and outputs it to a data storage part 110. The data storage part 110 stores the program information, and a display data preparation part 111 prepares and outputs an image data of the program chart based on outputted program guide information. At this time, the display data preparation part 111 refers to the dictionary of the character code stored in a memory 114 and converts the character code included in the program information to a display data of the character corresponding to it. Then, the image date of the program chart outputted from the display data preparation part 111 are inputted to an image synthesis part 106. Images outputted from the image synthesis part 106 are displayed on a display part.

摘要： PROBLEM TO BE SOLVED: To perform the optimum screen display by controlling a screen state in the situation when external information is shown on a TV receiver. SOLUTION: When a telephone line is connected to an external information input-output terminal 109, a modem 111 modulates, demodulates data and corrects errors. Then, a CPU 35 processes the data, creates document data in an HTML format and outputs it to a display control processing circuit 112 through a data bus 114. When a data transfer speed is slow due to the congestion of a connected line, the size of a screen is changed in accordance with the speed. That is, a television image is shown in a large size on a screen and an HTML document video part is shown in a small size by means of control signals a and b of the output of the circuit 112. Thereby, when information such as an internet, etc., can not immediately be shown, a waiting state can be improved. Also, in sound, when a transfer speed is slow, television image sound is increased and HTML document related sound is reduced at the time of synthesizing in a sound synthesizing circuit 107 by means of a control signal c of the output of a sound control processing circuit 113.

摘要： PROBLEM TO BE SOLVED: To prevent a user from having nothing to do and make the elapse state of a wait time easy to know by making a bar display showing the elapse of an in-actuation period or data read-in period on a television or VTR screen. SOLUTION: The screen of TV is displayed to prevent the user from having nothing to do and the large-sized bar display showing the elapse of the starting of the Internet is provided at part of the TV screen. The figure shows how display screens 1-4 of the display change when a connection with the Internet is started. Thus, a TV image is displayed on the entire screen of the display to prevent the user from feeling bored until the Internet connection is completed, and the bar display showing the elapse of the actuation is displayed on the TV screen to let the user easily know the elapse state. Then the screen 4 appears on the completion of a read of a browser and thus the screen is switched automatically to the screen of the Internet, so that the user starts operation on the screen of the Internet thereafter.

摘要： PROBLEM TO BE SOLVED: To provide the wide conversion circuit for an image signal in which wide conversion processing with less image quality deterioration is realized and a TV image with high image quality is obtained. SOLUTION: Motion correction interlace - noninterlace scanning conversion is conducted based on a motion vector for MPEG video coding with respect to a decoded image signal of digital broadcast and wide conversion signal processing such as vertical compression and vertical expansion is conducted by using the noninterlace scanning signal. Then the noninterlace scanning signal or the signal converted again into the interlace scanning signal is used to generate a signal suitable for a display section whose aspect ratio is 16:9 or 4:3.

摘要： PROBLEM TO BE SOLVED: To efficiently generate a motion vector for each picture element based on the motion vector of MPEG video encoding by dividing a macro block into four areas and performing simple two-vector operation processing concerning respective motion vectors. SOLUTION: Concerning a data stream signal DBS of digital broadcasting, a video encoding data stream signal VBS is extracted at a separation part 1 and an image data signal S1, motion vector MV and macro block information MB are outputted at an IVLC part 2. At a motion vector processing part 4, the signal processing of motion vector generation is performed, and a motion vector MVE for each picture element is provided in its output. A motion vector selection part 6 selects a motion vector required for operation processing out of these motion vectors and outputs it. Then, in the case of simple two-vector operation processing, a motion vector V0 and a one of motion vectors V1, V2, V3 and V4 corresponding to the area of a picture element (Xa,Ya) in the macro block are outputted.

摘要： PROBLEM TO BE SOLVED: To display an image without deterioration in the image and to prevent the circuit scale from being increased by reading a standard television signal synchronously with a stable oscillation output in the case of reading the standard television signal from a storage section in an N-multiple means so as to conduct double speed conversion and correcting a time base of the signal. SOLUTION: A received standard television signal is written in storage sections 105a, 105b used for double speed conversion in an N multiple means 105 synchronously with an oscillation output from a 2nd oscillation means 107 in common for the double speed conversion. The standard television signal of N multiple speed whose time base fluctuation having been in existence at the reception is outputted by reading the written standard television signal from the storage sections 105a, 105b synchronously with the oscillation output from the 1st oscillation means 124. The standard television signal of N multiple speed is given to a display device 126 synchronously with a horizontal drive pulse from a horizontal drive pulse generating means 109 and displayed thereat.

摘要： PURPOSE:To always provide high-quality pictures by eliminating the picture quality deterioration of video signals after waveform equalization by performing optimum picture quality correction to the video signals after waveform equalization based on the state of input video signals and the information of waveform equalization. CONSTITUTION:An average noise component contained in the video signal is detected by a noise detection circuit 113 and outputted to a picture quality control circuit 114. A tap coefficient arithmetic circuit 116 prepares information for estimating the state of equalized images from tap information at the time of waveform equalization and outputs it to the circuit 114. The circuit 114 prepares picture quality control information and outputs it to a picture quality correction circuit 115 based on noise information outputted from the circuit 113, image state information outputted from the circuit 116 and GCR peak level information prepared from a reference (GCR) signal for ghost removal inserted to the inputted video signal. Thus, high-quality pictures can be always provided without causing deterioration of an S/N or conversely causing unsharpness after waveform equalization.
