Abstract

A digital broadcasting receiver includes a digital tuning section having a plurality of tuners which receive digital broadcasting and output video signals of programs as well as a copy control signal, and a controller which selects one of video signals supplied from the tuners based on the copy control signal supplied from the digital tuning section. The foregoing structure allows the receiver to output the videos of programs free from intermittence at the beginning of the program of which copy control signal is switched from the previous one.

Claims

1. A digital broadcasting receiver comprising:

a digital tuning section including a plurality of tuners for receiving digital broadcasting and outputting a video signal of a program as well as a copy control signal; and

a controller for selecting one of the plurality of tuners, to which selected tuner the video signal of the program is input, based on the copy control signal supplied from the digital tuning section.

2. The digital broadcasting receiver of claim 1, wherein the controller includes:

a reservation information recorder for recording reservation information in advance about a program designated by a user;

a copy control signal decoder for decoding copy control signals of a plurality of programs received by the digital tuning section; and

a tuner switcher for selecting one of the plurality of tuners, to which selected tuner the video signal of the plurality of programs is input.

3. The digital broadcasting receiver of claim 2, wherein the controller further includes an identical quantity of to-be-recorded video producing sections to a quantity of the tuners, each one of which to-be-recorded video producing sections produces a to-be-recorded video in accordance with the copy control signal based on the video signals of the programs supplied from the plurality of tuners.

4. The digital broadcasting receiver of claim 3, wherein when a consecutive plurality of programs are received and the reservation information recorder detects that the copy control signals, decoded by the copy control signal decoder, of the plurality of programs are different from each other, the reservation information recorder switches a tuner, from which video signals of the plurality of programs are supplied to the tuner switcher, to another tuner at a given time.

5. The digital broadcasting receiver of claim 4, wherein the plurality of programs are received based on reservation information recorded in the reservation information recorder.

6. The digital broadcasting receiver of claim 5, wherein the reservation information is EPG (electronic program guide) information received by the digital tuning section.

7. The digital broadcasting receiver of claim 5, wherein the copy control signal includes EPG (electronic program guide) information received by the digital tuning section.

8. The digital broadcasting receiver of claim 4, wherein the given time is a predetermined time before a first program is switched to a second program that is received consecutively following the first program.

9. The digital broadcasting receiver of claim 8, wherein the given time is one minute.

10. The digital broadcasting receiver of claim 4, wherein a video signal, selected from video signals of a plurality of programs which are input to the tuner switcher, is a previous reserved program of consecutive programs to be received, and a video signal of another program out of the plurality of programs is a latter reserved program of the consecutive programs to be received.
