ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a signal receiving device and a signal receiving method and is suitably applied to a signal receiving device and a signal receiving method for obtaining audio/video signals by receiving telecast waves and outputting said audio/video signals to an external recording device.
DESCRIPTION OF THE PRIOR ART
In recent years the telecasting system for transmitting television signals upon digitizing via the satellite such as broadcast satellite and communication satellite, and receiving and viewing the telecasting signal from the satellite by means of the digital satellite telecast receiving device provided in each home has been widely spreading.
In this telecasting system, approximately 150 channels are available, and as compared with the conventional terrestrial waves, a great many programs can be broadcasted. And in order that the user can select the desired program correctly from among the enormous numbers of programs, the data of electronic program guide is transmitted as the telecast scheduled program information.
In the digital satellite telecast receiving device, an electronic program guide table is formed based on the electronic program guide data so that it can be displayed and the user can select the desired program by referring to this electronic program guide table.
The contents of this electronic program guide consist of the title of each program (program name), telecast time (date, and time period, etc.), the name of telecasting station, information on the viewing condition such as fee must be paid or not, the brief description of contents and additional information on such as the cast.
Furthermore, in the case of recording the program received by said digital satellite telecast receiving device under the condition where no digital satellite telecast receiving device is built in the recording device such as VTR (video tape recorder), generally, the audio video source received by the digital satellite telecast receiving device is put into the VTR and said VTR side records this audio video source.
Since the digital satellite telecast receiving device and the VTR are separate independent devices, in the case of recording the image received by the digital satellite telecast receiving device and the user wants to record the desired program, it is necessary that the digital satellite telecast receiving device side selects the desired program, while the VTR side conducts the required setting and operation so that the recording of the program selected by the digital satellite telecast receiving device side can be conducted according to the starting time of the program selected by the digital satellite telecast receiving device side. In short, when the user records the desired program, he is required to go through the complicated operation for multiple equipments.
Furthermore, in this case, as the digital satellite telecast receiving device side information to be recorded on the VTR side only audio and video signals of the program which are actually put on the air can be obtained. For example, since the electronic program guide information to be obtained at the digital satellite telecast receiving device side contains the contents as described above, it is sufficiently effective as the information of recorded program that can be referred after it is recorded. However, since the electronic program guide information is not recorded on the video tape recorded by the VTR, this is not effectively reflected as it is.
DISCLOSURE OF THE INVENTION
The present invention has been done considering the above points and is proposing a signal receiving device and a signal receiving method capable of offering the environment having satisfactory usability to the user and effectively reflecting the electronic program guide data information piled over the telecast wave even after the program is recorded on the VTR.
To obviate such problems according to the present invention,
we provide a channel selecting means for selecting channels; a telecast video output means for outputting video information of the channel selected by the channel selecting means; a program information image output means for forming program information image having the information related to the programs based on the program information data per program and outputting the video information of said program information image; a recording reserved program setting means for registering the desired program from among the telecast scheduled programs as the recording reserved program, and an output control means for executing the control to the program information image output means which causes the video information of the program information image corresponding to the recording reserved program to be sent out at the predetermined timing different from the broadcast time of the recording reserved program based on the contents of the recording reserved program set by the recording reserved program setting means and the control to the telecast video output means which causes the video information of the recording reserved program to be output at least during the time period of telecasting of the recording reserved program; and an operation control means for controlling the recording operation of the external recording device in which video information of the recording reserved program to be transmitted from the telecast video output means and the video information of the program information image to be transmitted from the program information image output means are entered corresponding respectively to the time period during which video information of the program information image is transmitted and the time period during which video information of the recording reserved program is transmitted.
By connecting external recording device in order that the video (audio) information to be sent out is supplied to the external recording device, the recording reserved program registered at the receiving device side can be reserved recording with respect to the external recording device, and when conducting this scheduled recording, the program information image concerning the recording reserved program formed based on the program information data can be recorded on the recording medium of the external recording device in addition to the recording reserved program.
According to the present invention as described above, the recording reserved program registered at the receiving device side can be reserved recording with respect to the external recording device, and simultaneously, when conducting this reserved recording, the title image on the recording reserved program formed based on the program information data can be recorded in addition to the recording reserved program, and thus, even though the receiving device and the external recording device are separate independent equipments, scheduled recording can be executed only by conducting the operation for an ordinary reservation recording setting and at the same time, this can be recorded with the title picture regarding said recording reserved program attached in every recording reserved program, and these can be used as useful recording history information when reproducing these, and thus, even though the receiving device and the external recording device are regarded as separate equipments, the AV system having the ease of use feature for the user can be formed and the receiving device capable of effectively utilizing the program information data obtained at the signal receiving device side can be realized.
Furthermore, according to the present invention, based on the contents of the desired program registered from among the telecast scheduled program of the selected channel as the recording reserved program, the control for outputting the video information of the program information image corresponding to the recording reserved program formed based on the program information data at the predetermined timing different from the broadcast time of the recording reserved program and the control for outputting the video information of the
