Abstract

A reception unit supports different types of TV broadcast systems (for example, NTSC-M/M, PAL-/I, PAL-B/G, SECAM-L/L′, PAL-D/D, etc.). The reception unit executes ghost reduction processing, three-dimensional Y/C separation processing, two-dimensional Y/C separation processing, one-dimensional Y/C separation processing, three-dimensional noise reduction processing, etc., for example, as video signal processing to put received video data (TV broadcast signal, video data from an external apparatus, etc.) into high image quality. The video signal processing to be executed is determined in response to the TV broadcast system type of the received video data. Accordingly, the video signal processing optimum for the TV broadcast system type of the received video data is executed.

Claims

1. An electronic apparatus capable of displaying video data on a display, the electronic apparatus comprising:

a reception unit receiving video data corresponding to one of different types of broadcast systems from an external apparatus; and

a video signal processing unit being coupled with the reception unit to receive the video data from the reception unit, the video signal processing unit executing video signal processing corresponding to the broadcast system type of the video data for the video data.

2. The electronic apparatus according to claim 1, wherein the video signal processing unit includes:

a unit executing one processing corresponding to the broadcast system type of the video data, among three-dimensional brightness (Y)/color (C) separation processing, two-dimensional brightness (Y)/color (C) separation processing, and one-dimensional brightness (Y)/color (C) separation processing as the video signal processing corresponding to the broadcast system type of the video data.

3. The electronic apparatus according to claim 1, wherein the video signal processing unit includes:

a unit executing one processing corresponding to the broadcast system type of the video data among three-dimensional noise reduction processing and color distortion correction processing as the video signal processing corresponding to the broadcast system type of the video data.

4. The electronic apparatus according to claim 1, wherein the video signal processing unit includes:

a unit executing ghost reduction processing as the video signal processing corresponding to the broadcast system type of the video data if the broadcast system type of the video data is a specific broadcast system type and inhibiting execution of ghost reduction processing if the broadcast system type of the video data differs from the specific broadcast system type.

5. The electronic apparatus according to claim 1, wherein the reception unit includes a TV tuner receiving a TV broadcast signal carrying video data.

6. The electronic apparatus according to claim 1, wherein the reception unit includes a TV tuner receiving a TV broadcast signal carrying video data and a video input port inputting video data from an external apparatus, and

wherein the electronic apparatus further includes:

a unit determining the type of video signal processing to be executed by the video signal processing unit based on the broadcast system type of the video data and information indicating which input source of the TV tuner and the video input port the video data is input from.

7. A video data reception method receiving video data to be displayed on a display of an electronic apparatus, comprising:

receiving video data corresponding to one of different types of broadcast systems from an external apparatus;

detecting the broadcast system type of the received video data; and

executing video signal processing corresponding to the detected broadcast system type for the received video data.

8. The video data reception method according to claim 7, further comprising:

executing one processing corresponding to the broadcast system type of the video data, among three-dimensional brightness (Y)/color (C) separation processing, two-dimensional brightness (Y)/color (C) separation processing, and one-dimensional brightness (Y)/color (C) separation processing as the video signal processing corresponding to the broadcast system type of the video data.

9. The video data reception method according to claim 7, further comprising:

executing one processing corresponding to the broadcast system type of the video data, among three-dimensional noise reduction processing and color distortion correction processing as the video signal processing corresponding to the broadcast system type of the video data.

10. The video data reception method according to claim 7, further comprising:

executing ghost reduction processing as the video signal processing corresponding to the broadcast system type of the video data if the broadcast system type of the video data is a specific broadcast system type and a step of inhibiting execution of ghost reduction processing if the broadcast system type of the video data differs from the specific broadcast system type.

11. A video data receiver comprising:

a reception unit receiving video data corresponding to one of different types of broadcast systems from an external apparatus; and

a video signal processing unit being coupled with the reception unit to receive the video data from the reception unit, the video signal processing unit executing video signal processing corresponding to the broadcast system type of the video data for the video data.

12. The video data receiver according to claim 11, wherein the video signal processing unit includes:

a unit executing one processing corresponding to the broadcast system type of the video data, among three-dimensional brightness (Y)/color (C) separation processing, two-dimensional brightness (Y)/color (C) separation processing, and one-dimensional brightness (Y)/color (C) separation processing as the video signal processing corresponding to the broadcast system type of the video data.

13. The video data receiver according to claim 11, wherein the video signal processing unit includes:

a unit executing one processing corresponding to the broadcast system type of the video data, among three-dimensional noise reduction processing and color distortion correction processing as the video signal processing corresponding to the broadcast system type of the video data.
