Description

  The present invention relates to an image display device with an ID display function and an image display system.

  A conventional image display device has an ID display as a separate casing, and is installed in a set with an image display device in a broadcasting facility, a relay car, or the like. For this reason, the installation space is increased, and the number of connection cords is increased, resulting in erroneous wiring and generation of noise.

JP-A-5-183878

  The present invention solves the above-described problems, and provides an image display device and an image display system that save space and energy when displaying an image and ID information related to the image, and reduce the number of connection cords to reduce erroneous wiring and noise. The issue is to provide.

  In order to solve the above problems, the image display device of the present invention receives an image and each signal of ID information or a composite signal thereof, and provides an image display unit in a display screen and an ID display unit in a blank portion. It is characterized in that ID information relating to an image being displayed is displayed simultaneously with the image.

  According to the present invention, the image and the ID information related to the image are displayed simultaneously on the same screen, so that the installation space is reduced compared to the conventional case, power consumption is reduced, and erroneous wiring and noise generation can be reduced. There is an effect of becoming.

  Hereinafter, the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a first embodiment of a display screen according to the present invention, in which an image having an aspect ratio of 16: 9 is displayed on the display screen 1 employing a liquid crystal panel having an aspect ratio of 4: 3, and an upper margin is displayed. An ID display unit 2 is provided in the part, and ID information related to the image is efficiently displayed. Also, a tally mark indicating the screen selection status is displayed on the right side of the ID display unit 2.

  FIG. 2 shows a second embodiment of the display screen according to the present invention, which is an example in which a plurality of ID display sections are set. ID display portions 4 and 5 are provided at the upper and lower portions of the image display portion 3 of the display screen 1 so that they are properly used depending on the type of ID information. In this embodiment, the screen selection status is determined by the color change of the display ID and the blinking operation.

  FIG. 3 shows a first embodiment of the system block of the present invention, in which signals from the image input unit 11 and the ID input unit 12 are superimposed by the signal synthesis unit 13. These combined signals are input to the image display device 15 via the communication system 14.

  The composite signal input to the image display device 15 is separated into an image signal and an ID signal by the signal separation unit 16, the display layout is determined by the image ID synthesis unit 17, and the liquid crystal display unit 19 is used as shown in FIGS. Is displayed. At this time, the screen selection status is simultaneously displayed on the display unit 19 in accordance with the tally signal 18.

  FIG. 4 shows a second embodiment of the system block of the present invention, and is an example in which the image signal and the ID signal are input separately in the image display device 24, unlike the example of FIG. Each signal from the image input unit 21 and the ID input unit 22 is input to the image display device 24 via the communication system 23.

  The signal input to the image display device 24 is displayed on the liquid crystal display unit 27 as shown in FIG. 1 or FIG. At this time, according to the tally signal 26, the screen selection status is simultaneously displayed on the display unit 27.

It is a 1st Example of the display screen by this invention. It is a 2nd Example of the display screen by this invention. 1 is a first embodiment of a system block according to the present invention. It is 2nd Example of the system block by this invention.
