Abstract

A video display system includes a video display unit, and an external unit configured to be communicatable with the video display unit. The video display unit includes a display panel and is configured to transmit specific information to the external unit. The specific information includes display panel information related to the display panel. The external unit is configured to derive a parameter from the specific information received from the video display unit and to transmit, to the video display unit, one of the derived parameter and related data related to the derived parameter. The parameter determines image quality.

First claim

What is claimed is:

1. A video display system comprising:
a video display unit; and
an external unit configured to communicate with the video display unit,
the video display unit including a display panel and configured to transmit specific information to the external unit, the specific information including display panel information related to the display panel, and
the external unit being configured to derive a parameter from the specific information received from the video display unit and to transmit, to the video display unit, one of the parameter and related data that is related to the parameter, the parameter determining image quality,
wherein the video display unit includes a sensor and is configured to generate the display panel information based on an output from the sensor, the sensor being configured to detect one or more of electric characteristics, optical characteristics, and environment of the display panel, and
wherein the external unit includes:
at least one memory configured to store content data and the parameter;
an information processing unit configured to perform one of an operation of processing the content data with use of the parameter and thereby generating processed content data, and an operation of generating metadata as the related data, the metadata being additional data of the content data and including the parameter; and
a distribution server configured to perform one of an operation of distributing the processed content data to the video display unit, and an operation of distributing, to the video display unit, the content data together with the metadata.

2. The video display system according to claim 1 , wherein
the content data includes video content data and content attribute data, and
the information processing unit performs one of an operation of processing the video content data with use of the parameter and the content attribute data and thereby generating the processed content data, and an operation of generating the metadata as the related data, the metadata being additional data of the video content data and including the parameter and the content attribute data.

3. The video display system according to claim 1 , wherein the video display unit performs one of an operation of displaying, on the display panel, a video based on the processed content data, and an operation of displaying, on the display panel, a video based on the content data while controlling the display panel based on the metadata.

4. The video display system according to claim 1 , wherein the specific information further includes user information.

5. The video display system according to claim 1 , wherein
the video display unit includes
a system circuit configured to decode one of the processed content data and the content data, and then to perform an image process thereon, and
a panel drive circuit configured to drive the display panel and to transmit the specific information to the external unit.

6. An external unit comprising:
a receiving section configured to receive specific information from a video display unit, the video display unit including a display panel, and the specific information including display panel information related to the display panel;
an arithmetic section configured to derive one of a parameter and related data that is related to the parameter from the specific information received by the receiving section, the parameter determining image quality;
a transmitting section configured to transmit, to the video display unit, one of the parameter and the related data derived by the arithmetic section;
at least one memory for storing content data and the parameter;
an information processing unit including the receiving section, the arithmetic section, and the transmitting section, the arithmetic section being configured to perform one of an operation of processing the content data with use of the parameter derived from the specific information and thereby generating processed content data, and an operation of generating metadata as the related data, the metadata being additional data of the content data and including the parameter; and
a distribution server configured to perform one of an operation of distributing the processed content data to the video display unit, and an operation of distributing, to the video display unit, the content data together with the metadata.
