IPTV/OTT set-top-box GSL Raven (GS С592)

IPTV/OTT set-top-box GSL Raven (GS С592)

General Satellite’s bestseller in the IPTV / OTT set-top box segment. This “workhorse” has a reasonable combination of quality and price:

  • Support of video and TV channels with maximum resolution up to Full HD (1080p).
  • HDMI output v. 1.4a (HDMI standard with improved 3D support).
  • Analog audio-video AV output with a 3.5 mm TRRS connector, allows you to connect old TVs with analog input through an adapter TRRS 3.5 mm – 3xRCA connector (“bells”, “tulips”). Moreover, if the old TV has a SCART input, it is possible to connect via an additional SCART – 3xRCA adapter.
  • Optical digital output S/PDIF “TOSLINK” for transmitting digital surround sound, compressed IEC 61937 standard. Allows you to connect home theater AV receivers that support Dolby Digital or Digital Theater System (DTS) surround sound formats. A particular advantage is the connection possible by optical cables, absolutelly defended to any electrical interference.
  • 100Base-T (Fast Ethernet) Ethernet input for connecting the set-top box to the Internet by connecting the set-top box with a router with a maximum speed of up to 100 Mbps. In case that the port of the router also supports the 100Base-T (Fast Ethernet) standard and the Ethernet cable is able to transmit data at the desired speed, the real speed in the home network will average 90-95 Mbit/s. Which is enough for broadcasting over a local network or from the Internet Full HD (1080p) video with a frequency of 60 fps. The transmission of which will require no more than 20 Mbps with stream compressed by the H.264 codec.
  • 2.4GHz wireless WiFi interface with IEEE 802.11 b/g/n support. The old IEEE 802.11n (WiFi 4) standard at 2.4 GHz theoretically supports a maximum speed of up to 150 Mbps. It would seem nice, but today there are WiFi routers in almost every apartment, and dozens of devices of members of the family living in the apartment connect to them: computers, IPTV / OTT STB, Smart TVs, smartphones, tablets, laptops, IP cameras, smart speakers, smart bulbs , smart sensors of all kinds, etc. And the frequency is only one and it has only 14 channels. Accordingly, in an apartment building all devices of the residents of their surrounding apartments compete for these channels. And in the evening rush hour, when most of the neighbors watch TV, the 2.4 GHz network bandwidth drops from 150 to 1 Mbit/s and lower. Making viewing even SD channels very uncomfortable. Therefore, it is currently not recommended to use this WiFi frequency in apartment buildings. Only in a private building, in the countryside.
  • Bluetooth wireless interface standard BLE 4.1. This interface is designed to connect such additional devices as remote controls with voice control, gamepads, air mouse, keyboards, headphones, microphones, IP video cameras, etc. The most common usage scenarios: control of a set-top box hidden behind a TV or built-in furniture, voice control / search in applications supporting this mode, game control, and much more. Standard 4.1 provides data transfer rates of up to 24 Mbps in the frequency band 2.402 GHz – 2.48 GHz. It is important to note the supported collaboration mode of Bluetooth and fourth-generation LTE mobile communications. It provides protection against mutual interference by automatically coordinating the transmission of data packets. To connect specific devices using this protocol, you will almost certainly need to integrate the Linux drivers of these devices into the set-top box software. This service is possible only with the wholesale order of STB.
  • USB 2.0 input with a speed of up to 480 Mbps and with a current strength of 500 mA for connecting USB flash drives with personal photos, audio and video content, and other peripherals. Plug-in flash drives can also use for functions such as Time Shifted TV / Pause Live TV and Digital Video Recorder (DVR). Despite the impressive theoretically achievable speed, the actual data transfer speed from a USB 2.0 flash drive is always much lower. The vast majority of the products of this standard on the market comply only with USB 2.0 Full-speed specifications with a data transfer rate of 0.5-12 Mbit/s. Which may not be enough to transmit Full HD 1080p 60 fps video. Devices with USB 2.0 Hi-speed specification (25-480 Mbps) are quite rare and expensive. Therefore, in fact, a USB 2.0 input is an additional connector for connecting low-speed USB flash drives, as well as additional peripheral devices. Such as additional remotes with voice control, gamepads that do not support Bluetooth, manipulators such as “mouse”, keyboards, etc. Suitable for comfortable viewing videos with a resolution up to Full HD 1080p 30 fps. Higher resolution video can play poorly, with jerks and delays, especially in highly dynamic scenes, depending on the actual capabilities of the USB flash drive or disk.
  • An input for connecting a remote IR sensor with a Jack 3.5mm jack, in case you need to hide the set-top box behind a TV or expand the reception area of ​​IR signals from the Remote.

StingrayTV is an authorial version of the popular Linux-based OS, designed specifically for IPTV / OTT operators. GS Labs own product. The GSL Bullfinch STB allows you to use as a source of TV signal:

  • IPTV / OTT signal received from the DRE Advanced Media Platform (formerly Stingray Stream).
  • M3U playlist.
  • IPTV signal received from headends with support for the Session Announcement Protocol (SAP). Headends from WISI, Terra, etc.
  • IPTV / OTT signal received from the IPTVPORTAL platform. Available only with condition of minimum order of 1,000 set-top boxes.

In order for the STB to work with the desired type of signal received from a particular operator, the must be used firmware appropriate to the signal and source. This point must be taken into account when ordering STB from the manufacturer or even more so when purchasing from a distributor. In addition, the manufacturer offers operators the service of “locking” STB, i.e. binding them to a specific IPTV / OTT source of a particular operator. Such STB can only be unlocked in the production of consoles in St. Petersburg or not, depending on the degree of protection against reflashing that the operator who ordered the locked STB chose.

Before buying a set-top box, it is advisable for the subscriber to find his own interactive television operator and make sure that he is ready to provide the M3U playlist, multicast stream with SAP support, or a user account from the platform or video service. Otherwise, the subscriber will be able to use only free playlists and content, taking into account their limitations: low bitrate streams, an abundance of advertising, not regular availability of services.

GSL Raven STB were developed by Tsifra LLC (TM GS Labs), manufactured by GS Group holding companies in Gusev, Kaliningrad Region, tested and flashed at GS Labs in St. Petersburg.

The GSL Raven is hardware identical to the GS C592, but differs in software. GS C592 STB are designed to work in the ecosystem of the Tricolor operator and are “locked” for this operator. GSL Raven STB are designed to work on the network of other telecom operators and Internet providers, and can be either “locked” under the customer’s source and network, or be able to reconfigure and reflash. Flashing GSL Raven supplies with firmware for GS C592 (Tricolor firmware) is not possible and may lead to non-warranty damage. The reverse operation of the GS C592 firmware by firmware for GSL Raven STB is also unacceptable.
