Modern television has long ceased to be just scheduled broadcasting, turning into an interactive platform where the user decides what and when to watch. Technology multi-screen from Rostelecom has become a real breakthrough for those who are accustomed to value their time and do not want to depend on the broadcast schedule of channels. This function allows you to broadcast images from a smartphone or tablet directly to a large TV screen, providing maximum comfort for viewing content in high definition.
Owners of devices based on the operating system Android often face difficulties during the initial setup, since the application interface can change, and network requirements remain strict. To enjoy movies and TV series without delays, you need to properly prepare your hardware and software. In this article we will analyze in detail all the stages of connection, paying attention to the nuances that are often overlooked.
Before moving on to direct actions, you should make sure that your tariff plan supports this option, since in some basic packages it may not be available or require additional activation in your personal account. The key condition for stable operation of the multiscreen is that all devices are on the same local Wi-Fi network. If the router distributes the network at a frequency 5 GHz, this will significantly improve the quality of video stream transmission and reduce the likelihood of sound and picture desynchronization.
Checking compatibility and preparing equipment
The first step towards convenient viewing is a thorough check of the technical arsenal. Not all TV models and set-top boxes support modern data transfer protocols equally well. Make sure that your set-top box Wink or InterZoom has the latest version of the software, as older firmware may not contain the necessary modules for receiving signals from mobile devices.
The smartphone or tablet must also meet the minimum system requirements. Usually this is Android version 7.0 and higher, although for new codecs to work correctly it is better to have a more recent OS. Check the availability of free space in the device's memory, as the broadcast application can create temporary buffer files, the overflow of which will lead to failures.
Particular attention should be paid to the router. If you are using older equipment that only supports 802.11n, the data transfer speed may not be sufficient for streaming 4K video. In this case, it is worth considering the possibility of upgrading your network equipment to standard Wi-Fi 5 (ac) or Wi-Fi 6 (ax).
⚠️ Attention: When using a guest Wi-Fi network in a hotel or public place, the multiscreen broadcast may be blocked by the router's security settings, which isolate devices from each other.
Below is a table that will help you quickly navigate the equipment requirements:
| Device type | Minimum requirements | Recommended parameters |
|---|---|---|
| TV set-top box | Wink / InterZoom (any) | Wink with 4K support, latest firmware |
| Smartphone/Tablet | Android 7.0+ | Android 10+, 3 GB RAM |
| Router | Wi-Fi 4 (802.11n) | Wi-Fi 5 (802.11ac) and higher, 5 GHz |
| Internet channel | 10 Mbit/s | 50 Mbit/s and higher for 4K |
Checking the firmware version on the set-top box is carried out through the settings menu. Find item About the system or About the devicewhere the current build number will be indicated. If the update option is available, be sure to use it before you start setting up the multiscreen.
Installing and configuring the Wink application
The central element of the ecosystem is the application Wink, which acts as a control panel and content source. You can download it from the official store Google Play, which guarantees the absence of malicious code and the latest security updates. After installation, be sure to log in using the same phone number or login that is specified in the agreement with the provider.
In the application settings, you must activate the device detection function. To do this, go to the Profilesection, then select Settings and find the item responsible for local devices or broadcasting. Make sure that the slider is activated, and when asked for permission to access the local network, you will answer in the affirmative.
The application interface may vary depending on the version Android and model of the smartphone, but the logic remains the same. Look for an icon that resembles a screen with waves or a rectangle with a triangle inside - this is the standard function symbol Cast or Broadcast. Clicking on this element starts scanning the network.
If the application does not see the set-top box, try rebooting the router by unplugging it for 10-15 seconds and then turning it on again. This will clear the DNS cache and update the lists of devices on the network.
In some cases, you may need to manually add a device by IP addressif the automatic search does not work. You can find out the IP address of the set-top box in the network settings of the TV itself or through the router’s web interface in the list of connected clients.
Step-by-step connection instructions
The process of connecting a smartphone and TV takes only a few minutes if you follow the algorithm. First, launch the app Wink on your mobile device and select any channel or movie you want to watch. In the player, find the button to call up the playback control menu.
Next, click on the broadcast icon. The system will offer a list of available devices on your network. Select your set-top box from the list. A connection confirmation request may appear on the TV screen, which must be accepted using the remote control.
☑️ Connection checklist
After successful pairing, the video from the smartphone will disappear and playback will continue on the big screen. Controls (pause, rewind, volume) remain accessible from the phone, which is very convenient. It is important not to lock the smartphone screen while viewing if you plan to use it as a remote control, although some models allow you to minimize the application to the background.
If you use the function multiscreen to play games or show a photo album, make sure that the screen orientation on the phone is fixed so that the image on the TV does not flip when you rotate the device.
What to do if the connection is lost?
Frequent connection interruptions can be caused by overload of the Wi-Fi channel by neighboring routers. Try changing the broadcast channel in the router settings to a less busy one (for example, to 1, 6 or 11 for 2.4 GHz) or switch to the 5 GHz band, where there is much less interference.
Solving common problems
Technical failures are inevitable, and most often they are associated with software conflicts or instability of the network connection. If you observe constant buffering (spinning loading indicator), try lowering the video quality in the player settings from Auto or 4K to 1080p or 720p. This will reduce the load on the communication channel.
Another common problem is desynchronization of the audio and video stream, when the actors’ lips move out of sync with their voice. This can be solved by restarting the application on the smartphone or completely turning off and on the set-top box. In rare cases, clearing the application cache helps Wink in the settings Android.
The “Device not found” error most often indicates that the phone and the set-top box are on different subnets. This is relevant for complex home networks with several routers or Mesh systems. Make sure both devices are connected to the same primary gateway.
⚠️ Warning: Antivirus apps or firewalls on your smartphone may block the local connection. Try temporarily disabling protection or adding the Wink application to exceptions.
For advanced users, a debugging method is available via ADB, which allows you to diagnose network ports. The command adb shell netstat will help you see active connections, but requires a PC and special drivers.
Optimizing the quality of the video stream
To ensure that the picture is clear and the sound is voluminous, it is not enough just to connect the device. You need to configure the output settings. The application Wink has playback quality settings, where you can force the maximum resolution if Internet speed allows.
Use a cable connection for the set-top box if possible. A connection via LAN guarantees stability, while Wi-Fi is susceptible to the influence of microwave ovens, Bluetooth headsets and even aquariums with water that absorb the signal.
It is also worth checking the settings of the TV itself. Turn on the mode Cinema or Movie for more natural color reproduction when watching movies. Turn off all picture “enhancers”, such as dynamic contrast or noise reduction, as they can introduce delay and artifacts when streaming.
Connection stability is more important than maximum speed: a stable stream of 20 Mbit/s is better than jumping from 10 to 100 Mbit/s.
Alternative methods broadcasts
If the standard application for some reason does not work or the functionality of the built-in multiscreen does not suit you, there are workarounds. The operating system Android has a built-in “Screen Cast” function, which duplicates the entire smartphone screen to a TV that supports the technology Miracast or Chromecast.
To do this, lower the notification shade on the phone, find the item “Broadcast” or “Smart View” (on Samsung) and select your console. In this mode, the TV displays everything that happens on the phone screen, including notifications and the desktop.
The disadvantage of this method is the higher power consumption of the smartphone and a possible decrease in picture quality due to additional compression of the video stream. In addition, some content-protected applications (DRM) may show a black screen when trying to externally broadcast.
Is it possible to broadcast via a USB cable?
Direct connection via a USB cable for transmitting a video signal to the Rostelecom set-top box is not supported by standard means. This would require special adapters (USB-to-HDMI) and support for MHL/HDMI Alt Mode on the smartphone side, which is implemented outside the operator’s ecosystem.
Frequently asked questions (FAQ)
Is it possible to use multiscreen without the Internet, only over a local network?
No, an active Internet connection is required to authorize the user, check the subscription and obtain a list of channels. The local network is used only to transmit the video stream from the router to the set-top box and the phone.
Why is there no sound on the TV, although there is sound on the phone?
Check the sound settings in the Wink application. Sometimes the audio stream does not automatically switch to the output device. Also make sure that the TV is not set to “Headphones only” mode or a similar restriction in the Android TV audio settings.
How many devices can simultaneously stream content?
The number of simultaneous connections depends on your tariff plan. Typically, basic plans allow you to watch on one device, while advanced plans allow you to watch on two or three. You can check the limits in the subscriber's personal account.
Does multiscreen work if the phone is unlocked with a code?
Yes, locking the phone screen does not interrupt the broadcast if it is already running. However, to start a new broadcast or control the player, the device will have to be unlocked.
