How do I send a message to a network-connected TV using Delphi7.

Ex.: I have a system that controls attendance queues, I need to show the next call password on a TV that is connected on the network.

  • Obs: you still don’t have a system that controls attendance queues, you’re still building it. What’s your question? What you already have ready?

  • I’m building the system, doubt is how to send the message with the next password to a TV connected to the network

  • Connecting the computer to a TV with HDMI output does not resolve?

  • But in this case how do I send the message? I need to work in a network

  • It depends on which connections your TV has. You can connect it to network?

    There’s no point in making an app for your TV to read these messages, and if the TV’s broken you have to buy one just like it. The business is to make a PC program that shows these messages and connect it on TV.

  • has yes, I can turn on the tv the way it is easier to work with the system

  • Why don’t you show this on the system itself and leave the TV connected to a PC?

Your problem is not exactly of programming but of understanding how the mechanism works.

I’m not saying it’s impossible for you to communicate with TV given the current technologies, but it takes work and it won’t bring anything useful.

This problem is solved as trivially as possible. You make a program to work on a normal computer and use the TV as a monitor. Whether this computer is networked or not will make a difference. Of course it will probably be to receive information from other computers indicating that the queue has to anadar, but then the problem is already another.

I will not go into detail because it is not the focus of the question, but most likely the other computers will communicate with this computer that will control the queue control application through the data bank that you have chosen to use.

  • I understood what you said. but in this case, how do I so that when the system is being on another pc (ie what does not have tv as monitor) understand that the message should be sent to what has tv as monitor?

  • You connect an HDMI cable between your computer and your television. You want to send the message to one or more Tvs?

  • no, I want several pcs connected to the network to send message to the tv

  • That’s what I said, the easiest thing is these computers, which are going to report that the queue went to the switchboard on the TV, record the information in the database. There are several ways to make the communication but I think for you that this raw is the simplest. And it’s not so simple. But it’s another question. Then you need to start doing something and see if you have specific questions.

  • Thanks for the tip... I’ll try it like this...

  • Use the INDY components. Create a Tcpserver on the computer where the TV will be on, and on the client machines a Tcpclient. Then Tcpserver will be "listening" to a certain port, and just have the clients send information to the server...
