Abstract

PURPOSE:To attain ease of data change and easy-to-see pattern display at a terminal equipment by giving information such as charge/time of each channel included in an in-band signal transmitted from the center to a character inserter so as to display it on a screen. CONSTITUTION:When a charged program is selected, a controller 12 gives character information such as charge/time to the character inserter 10 based on the in-band data as to a selected channel, the character inserter 10 takes synchronism by using a synchronizing signal from a descrambler 9 and displays the charge/time of the channel on the screen of a TV receiver. As a result, when a key input of 'charged channel selection OK' comes from a keyboard 13, the converter 8 is tuned to the channel. Then the signal releasing the scramble is given to a descrambler 9 at the same time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a terminal device in 0ATV that provides right-handed programs and the like. [Prior Art] As a conventional 0ATV terminal device, the one shown in FIG. 1 is known. Here, the TV signal from the center side passes through a converter 2° descrambler 3 via a branch, and is sent to the TV receiver. On the other hand, the data signal branched by the splitter 1 is demodulated by the demodulator 4, analyzed by the controller 1-roller 5, and it is determined whether the selected channel input from the keyboard 6 is permitted or prohibited. Ru. If permitted, the converter 2 is deconned to the selected channel by the control signal from the controller 5, and if the TV signal is scrambled, a descramble signal is sent to the descrambler 3. . Then, when the tunnel of the right-hand channel 1 program is selected using the key 6, the controllers 1 to 5 first specify a message channel that informs them of the fee and time of the right-hand channel, and display it on the screen of the TV receiver. Give the image of the message channel ↑・channel to the keyboard 6 in the current state and press the key of [Right-handed channel selection 01〈], then for the first time, the control signal for tuning the corresponding ↑・channel will be sent. , is sent from the controller 5 to the converter 2. [Technical issue 1] As described above, in the CA TV prostitution terminal equipment, it is necessary to indicate the price, time, etc. of all paid channels in the video of the message channel, and in addition, it is necessary to indicate the fee, time, etc.・Only the time cannot be displayed on the screen.And the video of the message channel must be changed every time the time changes. [Objective of the Invention] The present invention was made based on the above circumstances. This allows in-band data from the center to be processed on the terminal side and displayed on the screen, and information such as the fee and time of the channel can be displayed for advantageous programs without using a message channel. facilitates data changes;
In addition, we aim to provide a CATV terminal installation where the screen display on the terminal is easy to see. (Nursing of the invention) For this purpose, the present invention analyzes the data signal inputted to the converter from the center side by the demodulator and the data signal taken in by the demodulator, and enables/disables the selected channel. d3, which determines the value and tunes the converter, sends information such as the fee and time of each Bouyannel included in the in-band sent from the center to the character inserter, and is configured to accept the information displayed on the screen. It is characterized by: [Embodiment 1] An embodiment of the present invention will be specifically described below with reference to FIG. 2. In the figure, reference numeral 7 denotes a splitter, which branches the data signal from the TV double signal sent from the center side 1) t +. TV Shintan converter 8. Descrambler 9a3
and is output to the TV receiver via the character inserter 1o, the data signal is demodulated by the demodulator 11, and the data signal is output to the TV receiver via the character inserter 1o.
Herola 12 is analyzed. Channel selection data is input from the keyboard 13 to the controller 12, and it is determined whether the channel is permitted or prohibited. If the result of the determination is permission, a control signal is given to the converter 8 to tune to that channel. Furthermore, if the block has been scrambled, a descramble signal is given from the controller 12 to the descrambler 9. If the selected channel is an advantageous program, the controller 12 gives character information such as charge and time to the character inserter 10 based on in-band data about the selected channel,
The character inserter 10 synchronizes with the 110 signal from the descrambler 9 and displays the charge, time, etc. of the channel on the screen of the TV receiver. As a result, the keyboard 13 displays “Right O’1 channel selection OK.”
If you have the key power of J, converter 8 will be added to the channel.
Tune. At the same time, a signal to descramble is given to the descrambler 9. Note that in the above embodiment, the case where the selection of the desired channel is permitted is explained in 81, but if the selection is not permitted, a message indicating that the desired channel is not permitted may be displayed on the screen. [Effects of the Invention] The present invention has been described in detail above, and is advantageous because the terminal is equipped with a key ↑/actuator inserter, and the fare and time can be displayed on the screen using information from in-band data on the center side. When changing the program fee/time, there is no need to change the message channel image, the negative 1B on the center side can be reduced by 1, and what's more, at the μm end, the fee, time, etc. can be displayed for the selected M groups. It has advantages in use, such as making the screen easier to read.
