Digital signage is the category: any screen showing scheduled content that is updated remotely. Indoor TV and indoor media (“TV indoor” and “mídia indoor”, as the Brazilian market calls them) are the names for that screen when it sits in an enclosed space — a shop, a reception area, a waiting room. Corporate TV is the same screen turned towards the staff. Underneath, it is always the same three parts: a screen, something that plays the content and software that updates it from afar. What changes from one quote to the next is not the name, it is four answers: whose content it is, who watches, which screen and who updates it.
Why there are four names for the same screen
Because each name circulates in a different corner of the market. “Digital signage” is the term used by screen manufacturers and by the international market. “Indoor media” is advertising vocabulary. “Corporate TV” belongs to internal communication. And “indoor TV” — TV indoor — is the name Brazilian retail hears the most. All four circulate at the same time, and the buyer receives quotes that seem to be about different things.
In Brazil, the name “TV indoor” still carries a specific image — even for those who sell it. In the Café & Tech Podcast episode behind this article, streamed live on 18 December 2024, the perception shows up like this:
"…the name Indoor TV, everybody thinks of that little box (…) that the thing has to be done manually and does not update from the cloud. If it updates, it is a workaround, you have to go around using Google Drive…" Statement from the episode of 18 December 2024, linked at the end of this article. Translated from Portuguese.
It is worth reading that line for what it is: the portrait of a perception, not a technical definition. The little box with a USB stick exists, but it is one way of setting up the screen, not the meaning of the name. In the way the market organises the terms, the relationship is different. The digital signage glossary by Progic (in Portuguese) defines it like this, in our translation: “Digital signage is the term that covers every application in this market, such as digital indoor media, digital outdoor media, indoor TV, in-store TV, corporate TV, among others.” And further on: “Digital indoor media / indoor TV – These are the digital signage screens installed in enclosed spaces.”
In other words: every indoor TV is digital signage, and neither name is “more technological” than the other. The same episode says, right afterwards, the line that supports this reading:
"…the technology built into all of this (…) is the same technology used in different strategies, in different segments, in different places." Statement from the same episode. Translated from Portuguese.
The map of the terms
One row per term, so you recognise the vocabulary when it shows up in a quote. “Signage” on its own simply means the signs, boards and notices of a place; digital signage is that done with screens.
| Term | What it is | Where it shows up | Who tends to use the name |
|---|---|---|---|
| Digital signage | The category: electronic screens in place of traditional signage, with content managed by software. | From the airport video wall to the TV behind the counter. | Screen manufacturers, software suppliers, the international market. |
| Indoor TV (TV indoor) | The digital signage screen in an enclosed space. | Shop, clinic, gym, restaurant, reception area. | Brazilian suppliers serving retail and services. |
| Indoor media (mídia indoor) | The same enclosed space, seen as a media space. The Progic glossary treats it together with indoor TV. | Malls, gyms, lifts, screen networks. | Agencies and screen networks — and also those who use it as a synonym for indoor TV. |
| Corporate TV | Digital signage inside the company, as an internal communication tool. | Canteen, factory floor, office. | HR and internal communication. |
| DOOH (digital out-of-home) | Digital media “out of home”. The Progic glossary lists the acronym as a synonym for digital signage. | Screens in places people pass through, indoors or outdoors. | The advertising market, when the screen is sold as space for advertisers. |
Notice what the table does not separate: technology. No row requires equipment that another forbids. That is why comparing quotes by name leads nowhere — and why the four questions below are worth more than the glossary.
Question 1 — whose content is it?
At one end, the content is yours: this week's promotion, the service the customer does not know you offer, the opening-hours notice. At the other, the content belongs to advertisers who pay for the space — and the screen becomes a media business. They are two different projects, with different sums, and the name on the quote does not say which of the two is being offered.
It really does not. In queries run in Portuguese on 11 October 2026, Google's AI answer to “what is the difference between indoor TV and digital signage?” described indoor TV as a media format whose goal is “almost always monetisation through advertising”. On the same day, ChatGPT, answering a buyer's question, described indoor TV as the TV installed in the establishment “to broadcast your own content” and kept “indoor media” for advertising that is “frequently third-party” (both quotes translated from Portuguese). For one answer, indoor TV is the screen that sells ads; for the other, it is precisely the one that does not. Ask two sources and you get two opposite definitions.
Neither use is wrong. If your plan is to sell space, the article on starting a side income with one screen covers that calculation. If your plan is to show your own promotions, you need none of what exists to serve advertisers.
What to ask the supplier: is the content on my screen only mine, or do third-party ads come in? If they do, who decides which ones, and who gets paid for them? Can I block an advertiser that competes with me?
Question 2 — who watches?
At one end, the customer: whoever is in the shop, in the queue, in the waiting room. At the other, the staff — and that is when the same screen starts being called corporate TV. The Progic glossary defines corporate TV as “digital signage used inside companies as an internal communication tool” (our translation). The technology is the same; what changes is the content and the wall the screen hangs on.
When the viewer is the customer, the screen competes for attention with another screen. The episode says this about the waiting room:
"…your main competitor is your customer's phone." Statement from the episode of 18 December 2024. Translated from Portuguese.
That is why the screen at a point of sale is not scheduled like television. The length of the cycle, for example, depends on how long people stay in the room — the rule is in how long the indoor TV loop should be, and the waiting-room case is in TV for the dental office waiting room. When the viewer is the staff, the content changes in nature: indicator, target, shift notice. The two most common uses are in visual management on the factory floor and in indoor TV to engage staff during idle time.
What to ask the supplier: can I have different schedules on different screens — one for the shop floor, another for the staff room — under the same contract? How many screens with their own schedule does the plan cover?
Question 3 — which screen?
At one end, the regular Smart TV, the same one you buy for the living room. At the other, the professional signage display. This is not a marketing difference: the manufacturer itself treats them as distinct products, and you can see it in the warranty. In LG Brazil's warranty table (in Portuguese), checked on 11 October 2026, the categories appear separately:
| Category in LG Brazil's table | Warranty period |
|---|---|
| Television Plasma/LCD/LED/OLED | 1 year |
| Digital Signage | 3 years |
| LED Signage | 2 years |
| Hotel TV | 2 years |
| TV Signage | 1 year |
| Corporate TV (TV Corporativa) | 1 year |
The table shows two things. First: “digital signage” and “corporate TV”, here, are product line names — one more meaning for the same terms. Second: the signage display is not a TV with a higher price; it is another category, with another warranty period. The table is the Brazilian one; check the manufacturer's page for your own country.
The honest caveat about warranty. The warranty of a home TV usually does not cover continuous commercial use. The exact condition is in the warranty certificate of each model, not in the general table — read yours before hanging the screen in the shop. And be wary of any hours-per-day figure quoted from memory: ask the supplier for the model's spec sheet on the manufacturer's site.
That does not make the Smart TV the wrong choice. For a shop open during business hours that wants to show its own promotions, it does the job. The professional display exists for the cases in which the screen never rests, sits in the sun or is part of a large network. If your question is a shop window or a storefront, the comparison is in LED wall vs Smart TV on the storefront; if it is an upright screen, in vertical indoor TV without a kiosk.
What to ask the supplier: does the system run on the TV I already own, or does the quote include a specific screen? If it does, is it a home TV or a signage display — and what does that model's warranty certificate say about commercial use?
Question 4 — what plays the content and who updates it?
Every screen needs something to play the content. At one end, an app installed on the Smart TV itself, with the schedule built in a cloud panel. At the other, a separate device — player, box, mini PC — and, in the worst case, a USB stick someone has to swap by hand. This is where the “little box” from the episode lives: it is not indoor TV, it is one of the possible answers to this question.
The second half of the question weighs more day to day: who updates it, and from where? Changing the promotion from your phone, without going to the screen, is different from depending on a visit. The route without a device, and the care needed with generic hardware, are in indoor TV without a box.
To find out whether your TV and your network can cope, the episode offers a rule of thumb:
"…if your TV opens YouTube and the videos play well, it will work." Statement from the episode of 18 December 2024. Translated from Portuguese.
It is a starting test, not a report. The diagnosis of Wi-Fi, cable and freezing is in indoor TV freezing and the network requirements.
What to ask the supplier: is the app in the app store of my TV, this model? If not, which device do I need to buy? Do I change the content myself, remotely, or does it depend on someone going to the screen?
Where JMV Indoor sits on this map
In its simplest corner. By the four questions:
- Content: yours. You build the schedule with your own pieces.
- Who watches: customer or staff — the system is the same, the schedule of each point changes.
- Screen: a compatible Smart TV, horizontal or vertical.
- What plays it and who updates it: the JMV Indoor app, downloaded from the Smart TV's official store, and an online panel opened in the browser on a phone or a computer.
Compatibility, exactly as it appears in the requirements on the site: Samsung (Tizen), Google TV, Amazon Fire Stick, Roku TV and Roku Stick. LG (webOS): works on some models; the app is under review in the LG store. Confirm your model before subscribing. HDMI alternative, for a TV without the app: Amazon Fire TV Stick, Chromecast or Android TV Box. Before buying anything, see which TVs the app runs on and check your model.
Plan prices are always up to date in the plans table, and there is a 30-day trial with no credit card. And if your doubt is not between the names in this article but between a channel on the internet and the screen in the shop, the right article is web TV vs indoor TV: which one to get. The extended definition of indoor TV, with the environments where it works best, is in the SiteHost article on what indoor TV is and why your company needs it (in Portuguese).
Checklist: what to ask any supplier before signing
It applies to any quote, with any of the four names in the header — ours included:
- Whose content is it? Only mine, or do third-party ads come in? Who decides and who gets paid?
- Does it run on the TV I already own? Is the app in this model's app store, or do I need a device on the HDMI port?
- Who updates it, and from where? Me, from my phone, or does someone have to go to the screen?
- What happens when the internet goes down? Does the screen keep showing what it already had, or does it go dark? Ask for the answer in writing.
- Does the app start by itself when the TV turns on, and can I schedule by day and time, with different schedules on different screens?
- Can the screen stand upright? Confirm the orientation for your model.
- What does the screen's warranty certificate say about commercial use? It applies to the TV you already own and to the one included in the quote.
- Is there a lock-in period? Can I test with one point before signing for the whole network?
If the supplier answers those eight well, the name given to the product matters very little.

The excerpts from the episode
The excerpts below come from the episode “Digital Signage: A Solução para Melhorar a Comunicação em Empresas e Consultórios Indoor!”, from the Café & Tech Podcast, streamed live on 18 December 2024, in Portuguese; the translation is ours. The video's automatic captions get the terms wrong; here they are corrected, and anything in square brackets is a transcription fix, not added content. The captions do not mark who is speaking, so the lines are attributed to the episode, not to a person.
An anchor in time, and it matters. The episode is from December 2024. Prices, the list of compatible TVs and the app name mentioned in the conversation belong to that period — in the recording the app is called JMV Play; today it is called JMV Indoor. Everything this article states about the product was checked on the site on 11 October 2026, not taken from the conversation. Conversion percentages and claims of exclusivity made in the conversation are not endorsed here: they have no verifiable public source.
Excerpt 1 — the name “indoor TV” and the little box
Excerpt 2 — the digital signage of malls and airports
Excerpt 3 — the same technology in different places
Excerpt 4 — the screen's competitor is the phone
Excerpt 5 — the YouTube test
Excerpt 6 — the app, as it was described in 2024

In the end, the question in the title has a short answer: it is the same thing underneath. The answers to the four questions define the price and the day-to-day work; the name on the quote defines nothing. Someone who only wants to show their own promotions to customers, on a Smart TV, updating from the panel, is in the simplest corner of the map — and does not need to buy the most expensive corner just because the quote said “digital signage”.
