  • Patent number: 7607151
    Abstract: An electronic program table processing apparatus can obtain the number of receivable channels M and the standard number of channels N displayable on one screen. When EPG display data is generated, the apparatus examines whether or not the number M is smaller than the number N. If so, the apparatus generates the EPG to display the program information for M channels on one screen. If not, the apparatus generates the EPG to display the program information for N channels on one screen.

  • Publication number: 20070127882
    Abstract: A video recording apparatus, by comparing the preselected video recording duration with a preset reference video recording duration, assumes a video recording end time as an end time of a broadcast program next to the broadcast program for which the start of video recording is instructed in case the preselected video recording duration is shorter than the preset reference video recording duration, and assumes the video recording end time as the end time of the broadcast program for which the start of video recording is instructed in case that the preselected video recording duration is longer than the preset reference video recording duration.

  • Publication number: 20070044747
    Abstract: An air intake sound control structure comprises a sound guiding pipe, a sound producing body, and a silencing means. The sound guiding pipe is branched off from a branch portion formed on a part of an air intake flow passage of an automobile, communicating with the air intake flow passage. The sound producing body is held by the sound guiding pipe at the position spaced apart from the branch portion, thereby sealing the sound guiding pipe, and producing a sound at a frequency which corresponds to its own natural vibration frequency by its vibration. The silencing means is disposed on the side of the branch portion of the sound guiding pipe and canceling a sound at a target frequency for suppression out of the air intake sound. The sound generated by the vibration of the sound producing body is transmitted into a vehicle interior.

  • Publication number: 20050235313
    Abstract: A program information acquisition apparatus includes a program information acquisition unit, a program information accumulation unit, and a program information acquisition determining unit. In this configuration, a start of an acquisition operation by the program information acquisition unit is determined based on an information accumulation status of the program information accumulation unit. Thus, program information distributed from a desired reception target can be accumulated as the latest information as much as possible. Since unneeded program information is not acquired, program information acquisition with high energy saving effects is made possible.
