Each of the program / advertisement sending units 101, 115, and 117 includes a program recording unit 103 in which program data is digitally recorded on a disk or tape, an advertisement recording unit 105 in which advertisement data is recorded on a disk or tape, and an advertisement. And an advertisement ID adding unit 113 that generates information related to the advertisement, such as information specifying the advertiser of the advertisement and the length thereof. The advertisement data output from the advertisement recording unit 105 and the information related to the advertisement generated by the advertisement ID adding unit 113 are multiplexed by the multiplexing unit 111, and the main program data and the advertisement data are switched by the switching unit 109 to be multiplexed. Collected in 107.

  The multiplexing unit 107 forms a transport stream by multiplexing the digital stream of each program. In addition, a program table generated by the program table generating unit 119 is added to the multiplexing unit 107, and the program table is inserted into the transport stream at a substantially constant interval. The transport stream generated by the multiplexing unit 107 is modulated / amplified by the transmitter 121 and transmitted via the transmission antenna 123.

  On the receiving side of the digital broadcasting system shown in FIG. 2, the digital broadcasting received by the receiving antenna 125 is added to the receiver 127. The receiver 127 includes a tuner unit 131. The digital broadcast received by the reception antenna 125 is selectively received by the tuner unit 131, and the transport stream is restored. Then, it is output to the digital video 129 externally attached to the receiver 127 and is added to one input terminal of the switching unit 133.

  The digital video 129 is a digital recording / reproducing apparatus using a magnetic tape or disk as a medium, and records / reproduces the added transport stream. The transport stream reproduced from the digital video 129 is input to the receiver 127 and applied to one input terminal of the switching unit 157. The other input terminal of the switching unit 157 has an output of an advertisement storage unit 155 described later. Then, the output of the switching unit 157 is applied to the other input terminal of the switching unit 133.

  By switching the switching unit 133, it is possible to switch between the currently broadcast digital broadcast and the playback image of the digital video 129 recorded previously. The output of the switching unit 133 is applied to the program guide detection unit 137 and the switching unit 135. The program guide detection unit 137 detects and stores the program guide from the transport stream, thereby holding the program items existing in the transport stream, and closing the switching unit 135 when the user wants to watch the program. Only the program to be viewed is added to the decryption unit 139 and the advertisement ID detection unit 141.

  The decoding unit 139 decodes the MPEG2 stream of the program selected by the user, and outputs the image to the monitor 147 and the sound to the speaker 149. The advertisement ID detection unit 141 detects the ID of the advertisement multiplexed in the program, extracts the advertisement length and the advertiser information from the ID, and outputs them to the control unit 143.

  The control unit 143 is added with remote control information from the light receiving unit 153 of the infrared remote control, advertisement ID information from the advertisement ID detection unit 141, reproduction recording date / time information, and date information from a timer. The latest advertisement acquired via a line such as a telephone line is stored in the advertisement storage unit 155. The advertisement stored in the advertisement storage unit 155 is added to the switching unit 157 and replaced with the output from the digital video 129 under the control of the control unit 143.

  In step S205 (in the case of a video playback command), the digital video 129 is changed to a playback state. When the reproduction starts, the control unit 143 checks the advertisement ID output by the advertisement ID detection unit 141 in step S207, and when an advertisement is detected, the control unit 143 proceeds to step S209. In step S209, an advertiser is identified from the advertisement ID, the advertisement ID is sent to the advertiser through a line, and a response is awaited.

  In the next step S211, the advertiser's answer is determined, and if the advertiser gives an instruction to replace the advertisement, the process proceeds to step S213. If an instruction is given to use the advertisement stored in the medium as it is, step S217 is given. Migrate to

  In step S213, since a new advertisement is sent through the line, the switching unit 157 is switched to the advertisement storage unit 155 side in step S215 while the new advertisement is stored in the advertisement storage unit 155, and flows to the monitor 147 and speaker 149 side. And play new ads.

  If the process proceeds to step S217, the advertisement contained in the medium (digital video 129) is reproduced as it is. Even when a new advertisement is reproduced in step S215 or an advertisement stored in the medium is reproduced as it is in step S217, functions such as fast-forward and fast-forward reproduction are prohibited until the advertisement ends.

  When the reproduction of the advertisement is completed, in step S219, the switching unit 157 is returned to the digital video 129 side, and the reproduction is continued. In subsequent step S221, a remote control command is received from the user, and if the video is stopped in step S223, the process ends. If not, the process returns to step S207 to continue monitoring advertisements.
