Abstract

Disclosed herein is a digital broadcast receiver capable of performing synthesis on a commercial that a user desires. If the commercial satisfies the Jth condition, a synthesis unit reads image data assigned to the Jth condition from a storage unit. Further, if a sync signal has been detected, the synthesis unit synthesizes an image represented by the image data read from the storage unit with video represented by a video signal outputted from a decoder, and outputs the synthesized data.

Claims

1. A digital broadcast receiver comprising:

a receiving unit for receiving a digital signal sequence which is data of content transmitted by a digital broadcast;

a decoder for decoding the received digital signal sequence into content information, an audio signal, and a video signal;

a storage unit for storing image data;

a synthesis unit for reading image data stored in the storage unit and synthesizing an image represented by the image data with video represented by the video signal; and

a controller for controlling the receiving unit, the decoder, the storage unit, and the synthesis unit;

wherein

the storage unit further stores a condition for determining whether the transmitted content is a commercial with which an image is synthesized and information for designating image data assigned for each condition;

the controller determines whether the transmitted content satisfies a condition stored in the storage unit; and

if the controller determines that the transmitted content satisfies at least one of conditions stored in the storage unit, the synthesis unit reads from the storage unit image data designated by information for designating image data assigned for a satisfied condition stored in the storage unit and synthesizes an image represented by the image data with video represented by the video signal.

2. The digital broadcast receiver according to claim 1, wherein the controller uses the content information to determine whether the transmitted content satisfies a condition stored in the storage unit.

3. The digital broadcast receiver according to claim 1, wherein

the controller detects a sync signal from the received digital signal sequence;

and

if the controller determines that the transmitted content satisfies at least one of conditions stored in the storage unit, the synthesis unit reads from the storage unit image data designated by information for designating image data assigned for a satisfied condition stored in the storage unit and synthesizes an image represented by the image data with video represented by the video signal only during a period determined based on the sync signal.

4. The digital broadcast receiver according to claim 1, wherein

the controller detects a sync signal from the received digital signal sequence;

and

if the controller determines that the transmitted content satisfies at least one of conditions stored in the storage unit, the synthesis unit reads from the storage unit image data designated by information for designating image data assigned for a satisfied condition stored in the storage unit and synthesizes an image represented by the image data with video represented by the video signal only during a period over which the controller detects the sync signal.

5. The digital broadcast receiver according to claim 1, wherein the condition designates a company advertised in a commercial, a category of content, and a broadcast time.

6. The digital broadcast receiver according to claim 2, wherein

the controller detects a sync signal from the received digital signal sequence;

and

if the controller determines that the transmitted content satisfies at least one of conditions stored in the storage unit, the synthesis unit reads from the storage unit image data designated by information for designating image data assigned for a satisfied condition stored in the storage unit and synthesizes an image represented by the image data with video represented by the video signal only during a period determined based on the sync signal.

7. The digital broadcast receiver according to claim 2, wherein

the controller detects a sync signal from the received digital signal sequence;

and

if the controller determines that the transmitted content satisfies at least one of conditions stored in the storage unit, the synthesis unit reads from the storage unit image data designated by information for designating image data assigned for a satisfied condition stored in the storage unit and synthesizes an image represented by the image data with video represented by the video signal only during a period over which the controller detects the sync signal.

8. The digital broadcast receiver according to claim 2, wherein the condition designates a company advertised in a commercial, a category of content, and a broadcast time.

9. The digital broadcast receiver according to claim 3, wherein the condition designates a company advertised in a commercial, a category of content, and a broadcast time.

10. The digital broadcast receiver according to claim 4, wherein the condition designates a company advertised in a commercial, a category of content, and a broadcast time.

11. The digital broadcast receiver according to claim 6, wherein the condition designates a company advertised in a commercial, a category of content, and a broadcast time.

12. The digital broadcast receiver according to claim 7, wherein the condition designates a company advertised in a commercial, a category of content, and a broadcast time.
