HDMI 2.2 at CES 2025.
At CES 2025 in Las Vegas, the HDMI Forum announced the launch of the new HDMI 2.2 standard. The technology provides an impressive 96 Gbps of bandwidth and support for resolutions up to 16K. The new specification doubles the capabilities of HDMI 2.1 in chosen aspects. Along with the new standard, the "Ultra96" cables will be created, designed to exploit the full potential of this innovative technology.The last significant change to the HDMI standard saw the introduction of HDMI 2.1 in 2017. This standard allows data transfer at speeds of up to 48 Gbps and supports resolutions of up to 10K. In addition, the standard introduced support for 8K HDR, Dynamic HDR and offered the ability to display video in 8K at 60 Hz and 4K at 120 Hz. HDMI Forum explained how the new HDMI 2.2 standard will affect the development of VR (virtual reality), AR (augmented reality) and MR (mixed reality, also known as “spatial computing” in Apple terminology) technologies. With HDMI 2.2, creating and transmitting such content will become easier and more efficient. The new technology will also be beneficial to gaming companies that will be able to use its potential to improve user experience.
With the announcement of HDMI 2.2 by the HDMI Forum, data transfer rates have been increased from 48 Gbps to an impressive 96 Gbps. The standard supports resolutions up to 16K, as well as 12K at 120 Hz and 4K at 480 Hz. HDMI Fixed Rate Link (FRL) technology is behind the new video and audio capabilities. To fully realize the potential of HDMI 2.2, new Ultra96 cables are being developed, and Samsung has already unveiled a prototype of its HDMI 2.2 cable. Furthermore, HDMI 2.2 introduces an improved lip sync protocol known as Latency Indication Protocol (LIP). This feature will prove particularly useful in home theater systems working with soundbars, receivers and other devices, eliminating potential audio synchronization problems.
New monitors and TVs are gradually adapting to higher resolutions. 4K models have become the standard, and 8K models can increasingly be found in stores at affordable prices. Will the new standard quickly appear in stores? Note that the first TVs supporting HDMI 2.1 did not appear until 2019, two years after its release. So it is possible that we will have to wait for widespread adoption of HDMI 2.2. Nonetheless, the development of audiovisual technology is progressing rapidly, and the previously announced Ultra96 cables may come to market sooner than expected.
SMATV system in a single-family home.
SMATV is a system that allows the reception of television signals (including satellite, terrestrial, cable, etc.) throughout the house using a single set of antennas and equipment. With such a system, the signal can be distributed to several receivers, which is convenient, economical and practical. Such a solution is particularly popular in single-family houses, where there is often more than one TV set. SMATV system in a single-family house is a solution that allows efficient reception of TV signals, reduces the number of devices and cables in the building, and ensures high quality picture and sound. It is advisable to plan it properly at the stage of house construction to minimize possible problems related to wiring and signal access. The figure below shows a SMATV system based on the MRP-508 R68508 multiswitch.Elements of the system to consider during design and installation:
- FAMAVAL A9667 TRX-EL 100 satellite dish and A98257 Quattro LNB, which provides 4 signals of different band-polarization configurations (low and high band and horizontal and vertical polarization) to the multiswitch.
- DIPOL SMART HORIZON COMBO A2270 DVB-T2 terrestrial antenna with H/V polarization, suitable for receiving DVB-T2 digital terrestrial television in the VHF and UHF bands. The bypass allows it to operate in two modes – passive and active.
- Signal 5/8 R68508 multiswitch for RF/SAT signal management and distribution. The number of outputs depends on the number of terminal outlets. The choice of multiswitch should take into account the number of users and the type of installation.
- Cables and outlets: high quality coaxial cables with low attenuation (e.g. TRISET 302 series). TRISET 302 Eca E1005_250 Tri-shield type with a PVC sheath for indoor applications and TRISET 302 Fca E1008_250 Tri-shield type with PE sheath for outdoor applications. RF/SAT terminal sockets R694100 for connecting receivers.
New model of Ultimode OTDR: OR-30.
DIPOL now offers the Ultimode OR-30 L5835 OTDR in its range of devices designed for measurements of fiber optic systems. The most important feature of the device is the ability to perform measurements at 3 wavelengths – 1310 nm, 1550 nm and 1625 nm. This enables full diagnostics of the optical path in terms of fiber attenuation, splices, connectors, as well as events such as fiber bending and cable bending or breakage. A 1625 nm wavelength is available on a second OTDR connector equipped with filters for lower wavelengths, making it possible to perform measurements on active line in GPON networks and beyond. The dynamic range of 32/30 dB makes it possible to check connections on cables as long as tens of kilometers, including splitters.

Integration of an access control system with a Hikvision IP video intercom.
The diagram below shows a single-subscriber Hikvision IP video intercom system using the DS-K1T341AM-S G76158 access control videoterminal as the outdoor station and the DS-KH8350-WTE1 G74003 monitor as the indoor station. Both, the outdoor and indoor stations are connected to a PoE switch, but since the videoterminal does not support PoE standard, it was powered with 12 V/DC from a ZBF-12 V/4 A-17 Ah M1862 buffer power supply. The electric door strike is controlled by a built-in relay in the videoterminal with 12 V/DC voltage. The use of Bira XS00U-C G74242 electric door strike, which can operate continuously when powered by 12 V/DC, allows the door to remain open for a longer period of time if necessary. With the use of a video access control terminal, this type of solution can be used, for example, in a company where, during working hours, employees authorize themselves with their assigned rights, while people coming from outside can call the video intercom monitor. The videoterminal offers several modes of authorization – face recognition, Mifare card and password. After connecting the videoterminal to the Internet network, remote opening is possible using the Hik-Connect application.Diagram of a video intercom system based on DS-K1T341AM-S G76158 videoterminal.
CGI protocol for IP cameras and DVRs.
CGI is a protocol that an IP camera can use to communicate with a browser or application running on another server. Each CGI command is sent in the form of an HTTP request that can be executed by the camera. This makes it possible to perform a variety of operations related to the configuration, monitoring and control of camera functions, without the need for client applications or a browser interface. IP cameras can not only be easily managed, but also integrated with other systems, such as building automation. For Sunell devices, the following document is available explaining how various commands work.
