A method and apparatus for adjusting an embedded portion of a television signal. The embedded portion is adjusted such that a downstream receiver effects no change on a displayed video upon decoding the adjusted embedded portion.

Method and apparatus for adjusting an embedded portion of a television signal

A management tool is disclosed which aids the user in controlling the flow of data from one database table to another in computer memory, particularly when both the potential amount of data and the number of programmed functions which can be performed upon or be controlled by the data are large. In general, the tool is an interactive method of controlling the programmed flow of data in computer memory from an input table of rows and columns includes the steps of (1) generating a control grid (the crossbar) of rows and columns on a display monitor, (2) assigning each row of the grid to a respectively different column of the input table, (3) assigning each column of the grid to the role a different function a column of the input table may perform in generation of the output table, (4) inserting marks at selected intersections of rows and columns of the grid to set the functions selected columns of the input table perform in generation of the output table, and (5) controlling generation of the output table from data in respective input table columns selected by marks in accordance with the respective functions assigned to grid columns by the same marks.

A multi-step method enables a user to extract useful information from a complex relational database without needing to construct elaborate Structured Query Language statements or to become familiar with details of the particular data model involved. In particular, the method generates a table of output data from a relational database having one or more database tables made up of columns of attributes, rows instances, and one or more keys composed of one or more attributes each as elements. In the method, the steps include selecting an attribute from one of the database tables upon which to base an intermediate table, displaying a key of the database table containing the selected attribute, selecting an attribute element of that key for constraint, generating and displaying a list of alternative attribute sets the members of any of which when constrained will constrain the selected attribute element, selecting a set from that list of alternative attribute sets, generating and displaying a list of combinations of values for the selected attribute set, selecting one of the combinations of values from the list of value combinations, generating an intermediate table in accordance with the selected combinations of values from the list of value combinations, and generating the table of output data from the intermediate table. The intermediate table has only keys whose values have not been constrained.
