A video recording apparatus, wherein the electronic program table data of a broadcast program is acquired, and in response to a recording instruction for the broadcast program while viewing, the broadcast end time of the broadcast program recorded is acquired from the electronic program table data, so that the video information is recorded until the program end time from the time of the recording instruction. In the case where the broadcast program is delayed, the sum of the broadcast end time of the broadcast program to be recorded and a predetermined delay time is determined as the recording end time. From the time of the recording instruction to the program end time, the video information is recorded.

Abstract:
First, a unilayer wiring board is fabricated, which has wiring layers formed in desired shapes on both sides of an insulating base member; and a metal bump formed on the wiring layer on one side of the insulating base member. Then, a desired number of unilayer boards are prepared and stacked up. On that case, the board disposed in the uppermost layer is prepared without having a metal bump. The boards are positioned and stacked up in such a manner that a metal bump of one of adjacent boards is connected to a corresponding wiring layer of the other board. Thereafter, resin is filled into gaps between the stacked boards, and insulating layers are formed on both sides of a multilayer board obtained through the above steps, in such a manner as to cover the entire surface except pad areas defined at predetermined positions on the wiring layers.
