Home Media is the file manager of the embedded portal. Home Media provides access to the following services:

  • Network - network resources (directories and files) that are accessible on the local network by SMB and NFS protocols.
  • Records - a folder with recordings of media files (located on USB-media) that were created using the Records Manager or in the IPTV channels window.
  • Favorites - IPTV channels added to the favorites list.
  • USB-media - local resources (directories) of USB-drives that currently connected to the STB.
  • UPnP - network resources (directories) that are accessible in the local network by UPnP protocol.

This section is intended to configure and provide access to share network resources (directories and files located on network computers) that are accessible by SMB and NFSprotocols. Referring to these network protocols, network computers with shared folders are as servers, STB is as client.

Names of accessed directories are displayed on the top level of Home media window. In example, the directory data_AA (NFS access).

Network resource connection to STB is effective until it is disconnected on the STB side (including reset the STB settings), or until the corresponding settings on the server side is changed.

USB media

USB drive access mode

Settings of access to USB drives connected to the STB: System settings / Advanced settings / Storages access mode.

The folowing access modes can be set:

  • full access - read (play) and write (record) from/to drive are allowed;
  • read only - only read operation is allowed.

Full access to USB drives is required for the folowing functions:

USB drives connecting and displaying

When USB drive connects to STB being in operation, a message is displayed on the screen. The message indicates the USB drive has been successfully connected (mounted to STB). After STB rebooted, USB drive connects (mounts) automatically. After successful connection of USB drives, its icons are displayed in Home media window (on the upper level). In the example, single drive is connected with the name Kingston Data Traveler 3.0.

Current carrying capacity of USB interface

The number of ports and the maximum allowable current for various STB models are shown in the table below.

MAG- Type and number of ports and maximum allowed current
USB 2.0 USB 3.0
250 2х0,5А
254 2х0,5А
254w1/254w2 1х0,5А
256 1х0,5А 1х0,5А
322/322w1/322w2 2х1,5А
324/324w1/324w2 2х1,5А
349/349w3 2х0,5А
424/424w3 1х1А 1х1А

The maximum volume and type of hard disk without external power supply, which can be connected to the STB and work stably, depends on the current consumption of this device (taking into account peak loads). It should also be noted that the total load on the USB interface is made up of the load of individual devices that are simultaneously connected to the STB via USB ports (USB-drives, external keyboard, mouse, etc.).

Supported file system types

The file system types that various STB models support (can be used on external USB storage devices and network resources) are listed in the table below.

Example of network directory connecting by NFS protocol

In the context of the NFS protocol, STB acts as client and network computer - as server. Below is a description of the steps to configure access to the required directories (folders) on the STB side. The access setting on the network computer side (NFS server) must be preconfigured. For example, Configuring NFS Linux on Ubuntu.

  • In the Embedded portal go to Main windowHome MediaNetwork
  • Open Operations ⇒ Tools menu - press Menu and Right buttons on the remote.
  • In Operations menu, click Connect NSF / SMB.
  • In the Connect network folder window that opens, enter the access parameters and confirm the data with OK button:
    • Server address - IP address of the networked computer that acts as the NFS server;
    • Server folder - name of the network folder (directory) to which the access by NFS protocol configures;
    • Local folder - the name that assigns to this folder on STB. If value of this parameter is not specified, it is automatically assigned the same folder name as on the computer;
    • Connection type - you must select NFS value.
  • If the access settings is correctly configured on both sides (STB and computer), the message Network folder successfully mounted is displayed.Connected network folder should contain files of supported format: multimedia, playlists, subtitles.

Command to open Records menu is located at the top level of Home media window. Records command appears automatically when USB drive is connected to the STB and records folder is present on the USB drive. The records folder is created on USB drive automatically while recording on STB any of IPTV channels. 
STB recordings of media-stream fragments are automatically saved in the records directory of USB drive.
Records command is automatically deleted from Home media after USB drive is disconnected from STB or when the records folder is deleted from the USB drive.

The records can be created in one of the following ways:

  • Record Manager application (located in the Main menu of the embedded portal). In the Record Manager, the list of fragments to be recorded is pre-configured: you can specify IPTV channel, Start recording, End of recording, Recording time, Recording name, Device (USB-drive to sink the records).
  • Recording channel feature. It brings up while viewing a certain channel (in IPTV channels press F1 on remote. In Recording channel window the current channel recording is configured, similar to the Record Manager application.
  • Timeshift It is possible to save video fragment that recorded in buffer.

To perform writing on USB drive, full access mode to USB drive must be enabled: System settings / Advanced settings / Advanced / Drive access mode = full access.

The media records stored on the USB drive (the contents of the records folder) are located in folders whose structure includes the names of the channels on which the video fragments were recorded and the date:

1 level - folder with the same name as the channel from which the record was made (in the example - Sony SCI-FI);
2 level - folder with the same name as recording date (in the example - 2018-05-30);
3 level - files .ts whose name indicates the start time of the recording (in the example, files 09-43-11.ts, 10-16-41.ts).

Supported file types

Contents of network folders (SMB/NFS access) and USB-drives connected to STB, which user can work with, consists of subfolders and files. The following file types are used:

  • Multimedia files (video, audio, image) - to be played back (viewed), required file is selected and launched by OK button on RC. Files are played back using STB player. Only file formats supported by STB player can be displayed. Supported file formats are given below.
  • Playlists - files with extension m3u. Description how to handle with Playlists see below.
  • External (connected) subtitles files (.srt, .txt, .sub, .ass) - are used to display subtitles while playing back video files. Formats of supported subtitles for various STB models are described in IPTV channels section. To connect subtitles file user should open it and after rebooting STB - subtitles file becomes available for connection while watching channel.

      • Add entry to favorits (F3 on remote);
      • Copy entries to pass them to IPTV channels window (for this purpose go to IPTV channels and use Paste to add copied playlist entries);
      • Sort list entries by name, size, file type or file extantions;
      • Display only stream entry (not local files).
    • Start playing all records (F2 on remote) - start play back mode, where user can navigate through entry list similar to viewing channels in IPTV channels window.
    • Add all records to IPTV channels (F3 on remote) - adding all list entries to list of IPTV channels window.

External subtitles use

Supported external subtitles

Supported external subtitles are described in Subtitles subsection of IPTV-channels section.

Example of external subtitles connection

Example of scenario how to connect subtitles file to certain video file is below. For convenience, it is desirable to assign subtitles file with the same name as video file:

1. Open file with subtitles (in the example -

Image Documentation

2.After opening, the warning appears: 'Selected subtitles file will appear during next player launch' (after STB reboot).

3. Reboot STB, open required video file (in the example - law.and.older.401-test.avi).

4. While playing video file, open Subtitles window (use Menu on remote, and then Left, Right).
