TH20862A - Expanded Service Information Control (EDS) System - Google Patents

Abstract

Systems for processing television signals Containing Data components such as Expanded service information It contains a decoder for processing the data components that will produce the information of the time. Control devices that respond to information for The modifications of time information such as time of day, etc. are maintained in the system. The time information decoded from the video signal is compared with the time information that is decoded. Maintain in the system to determine the difference of time. If the time difference is within a predetermined range, such time difference indicates that the time information from the TV signal will be null, the control device will respond to the time difference in the interval. Preset range by preventing modification of time information maintained in the system, the user may provide an input signal through the device as the remote controller to control in the manner in which the device The controller will respond to the time difference.

Claims (9)

1. a system for processing television signals That includes Information components and contain information components. The system consists of one method for processing such data elements. To create the first data at It is information for the first moment. A second method is for generating a second, transient, second, and simplifying information. The modification of the second information occurred. By responding to the first such information A control method for processing the aforementioned first and second data to determine the difference of time between the first and second time. Indicated by the first and second transient information, respectively, in response to the control signal. For preventing such modifications Of the second such data If such time difference is within range one and to prevent Modification of the aforementioned two data Regardless of the said control signal, if the time difference falls within the second range excluding the first such range and the path for the generation of such control signals, then 2. System according to claim 1 in which the difference of the said period will fall within a certain period of time. The first and second ranges thereof Indicating that the second time will follow the first time 3. System according to claim 1 in which the difference of the aforementioned periods is in the second range. If the time difference is in the first such range, it indicates that the second time is after that time. 4. System according to claim 3, where the aforementioned means of generating such control signal consists of an output path for informing the user. To show that the time difference falls within the aforementioned range and the input path responding to user activation during the time when telling Such notifications are generated for such users. For generating such control signals 5. The system according to claim 4 also consists of a memory method for storing codes, such a control path will be responded to the specified value of the stored code. For the protection of the second method From making such adjustments 6. System according to claim 5 in which the stored code will be set to the predetermined value. In advance in response to the activation by the user. 7. The system according to Clause 6 also consists of A means for modulating such television signals from a number of television signals; The way of such memory A number of code stores Related to a reasonable number of such television signals Way of control It will respond to any appropriate one of the stored code. For protection The second way Not to modify If any one of the codes is stored a certain amount It has a value based on the preset value. 8. System according to claim 3, where the values of the first range will be values from 2 minutes to 15 minutes; And the values of the second range will be values greater than 15 minutes. 9. System according to claim 1, the first such transient information shall consist of the first time of day; And the second such transient information contains the second time of the day maintained by the system 1. 0. System according to claim 1, which the information for the first moment It also contains the first date and the second such transient information. Also contains the second date That is maintained by the said system
