True fans of online broadcasts know that there are applications similar to Periscope. Some of them were launched before the brainchild of Twitter. The most popular among these programs are those that will be discussed below.

7 facts about Meerkat

Twitch vs Periscope

Despite the general implementation in the field of video streaming, Twitch and Periscope are quite different from each other. The main differences are observed in the following categories:

What is Projector TV?

You can install this analogue of Periscope to access streams and conduct broadcasts only within the framework of operating system iOS, and versions eighth and higher are supported. Unfortunately, the Russian analogue of Periscope on Android is not yet available and the developer has not yet advertised the implementation of such a version.

In addition, for smartphones that are locked in any country, installation of the program is prohibited.

An obvious advantage of the Periscope analogue on the Russian market is the ability to post the broadcast on the VKontakte wall, and views on this social network are taken into account when compiling the overall popularity rating.

In general, we can say that programs similar to Periscope today cannot be called full-fledged analogues. They are either sold only for owners of apple products, or are tailored for completely different purposes. However, the video broadcasting market is just beginning to develop, and perhaps worthy competitors will soon appear among the Russian analogues of Periscope.

L-3 KEO provides the US Navy with a Universal Modular Mast (UMM) that serves as a lifting mechanism for five different sensors, including the AN/BVS1 optocoupler mast, high-speed data mast, multi-function masts and integrated avionics systems.

Advanced optronics (optoelectronics) give non-hull-penetrating mast systems a clear advantage over direct-view periscopes. The development direction of this technology is currently determined by low-profile optronics and new concepts based on non-rotary systems.

Interest in optoelectronic periscopes of a non-penetrating type arose in the 80s of the last century. The developers argued that these systems would increase the flexibility of the submarine's design and its safety. The operational advantages of these systems included displaying the periscope image on multiple crew screens as opposed to older systems where only one person could operate the periscope, simplified operation and increased capabilities, including the Quick Look Round (QLR) feature, which allowed for maximum reduction the time the periscope is on the surface and thereby reduce the vulnerability of the submarine and, as a consequence, the likelihood of its detection by anti-submarine warfare platforms. QLR mode value in Lately increases due to the increasing use of submarines to collect information.

In addition to increasing the flexibility of the submarine's design due to the spatial separation of the control post and optocoupler masts, this makes it possible to improve its ergonomics by freeing up the volume previously occupied by periscopes. Non-penetrating type masts can also be relatively easily reconfigured by installing new systems and implementing new capabilities; they have fewer moving parts, which reduces the life cycle cost of the periscope and, accordingly, the amount of its maintenance, routine and overhaul. Continuous technological progress is helping to reduce the likelihood of periscope detection, and further improvements in this area are associated with the transition to low-profile optocoupler masts.

Virginia class

In early 2015, the US Navy installed a new low-observable periscope, based on L-3 Communications' Low-Profle Photonics Mast (LPPM) Block 4, on its Virginia-class nuclear submarines. To reduce the likelihood of detection, the company is also working on a thinner version of the current AN/BVS-1 Kollmorgen (currently L-3 KEO) optocoupler mast installed on submarines of the same class.

L-3 Communications announced in May 2015 that its optical-electronic systems division L-3 KEO (in February 2012 L-3 Communications merged KEO, which led to the creation of L-3 KEO) received a competitive award A $48.7 million contract from Naval Sea Systems Command (NAVSEA) for the development and design of the low-profile mast, with an option to produce 29 optocoupler masts over four years, as well as maintenance. The LPPM mast program aims to maintain the characteristics of the current periscope while reducing its size to that of more traditional periscopes, such as the Kollmorgen Type-18 periscope, which began being installed in 1976 on Los Angeles-class nuclear submarines as they entered the fleet.

Although the AN/BVS-1's mast has unique characteristics, it is too large and its shape is unique to the US Navy, allowing the submarine's nationality to be immediately identified when a periscope is detected. Based on publicly available information, the LPPM mast has the same diameter as a Type-18 periscope, and its appearance resembles the standard shape of this periscope. The modular LPPM non-hull type mast is installed in a universal telescopic modular compartment, which increases the stealth and survivability of submarines.

The system features include short-wave infrared imaging, high-resolution visible imaging, laser ranging and a set of antennas that provide broad coverage of the electromagnetic spectrum. The prototype of the LPPM L-3 KEO optocoupler mast is currently the only operational model; it is installed aboard the Virginia-class submarine Texas, where all subsystems and operational readiness are checked new system. The first production mast will be manufactured in 2017, and its installation will begin in 2018. According to L-3 KEO, it plans to design its LPPM so that NAVSEA can install a single mast on new submarines and can also upgrade existing vessels as part of an ongoing improvement program aimed at improving reliability, capability and affordability. An export version of the AN/BVS-1 mast, known as the Model 86, was first sold to a foreign customer under a contract announced in 2000, when the Egyptian Navy contemplated a major upgrade of its four Romeo-class diesel-electric anti-submarine submarines. Another unnamed European customer has also installed the Model 86 on its diesel-electric submarines (DSS).

L-3 KEO, along with the development of LPPM, is already supplying the US Navy with the Universal Modular Mast (UMM). This non-penetrating type mast is installed on Virginia class submarines. The UMM serves as a lifting mechanism for five different sensor systems, including the AN/BVS-1, OE-538 radio tower, high-speed data antenna, mission-specific tower, and integrated avionics antenna tower. KEO received a contract from the US Department of Defense to develop the UMM mast in 1995. In April 2014, L-3 KEO received a $15 million contract to supply 16 UMM masts for installation on several Virginia-class nuclear submarines.

Another UMM customer is the Italian Navy, which also equipped its Todaro class diesel-electric submarines of the first and second batch with this mast; the last two boats were scheduled to be delivered in 2015 and 2016 respectively. L-3 KEO also owns the Italian periscope company Calzoni, which developed the E-UMM (Electronic UMM) electric mast, which eliminated the need for an external hydraulic system for raising and lowering the periscope.

The latest offering from L-3 KEO is the AOS (Attack Optronic System) commander's non-penetrating optronic system. This low profile mast combines the characteristics of the traditional Model 76IR search periscope and the same company's Model 86 optocoupler mast (see above). The mast has reduced visual and radar signatures, weighs 453 kg, and the diameter of the sensor head is only 190 mm. The AOS mast sensor kit includes a laser rangefinder, thermal imager, high-definition camera and low-light camera.

In the first half of the 90s, the German company Carl Zeiss (now Airbus Defense and Space) began preliminary development of its Optronic Mast System (OMS) optronic mast. The first customer of the serial version of the mast, designated OMS-110, was the South African Navy, which chose this system for three of its Heroine-class diesel-electric submarines, which were delivered in 2005-2008. The Greek Navy also chose the OMS-110 mast for its Papanikolis diesel-electric submarines, followed by South Korea who decided to buy this mast for its Chang Bogo-class diesel-electric submarines. OMS-110 type non-piercing masts have also been installed on the Indian Navy's Shishumar-class submarines and the Portuguese Navy's traditional Tridente-class anti-submarine submarines. One of the latest applications of the OMS-110 was the installation of universal UMM masts (see above) on the Italian Navy Todaro submarines and the German Navy Type 2122 class anti-submarine submarines. These boats will have a combination of an OMS-110 optronic mast and a SERO 400 command periscope (hull penetrating type) from Airbus Defense and Space. The OMS-110 optocoupler mast features dual-axis line-of-sight stabilization, a third-generation mid-wave thermal imaging camera, a high-resolution television camera and an optional eye-safe laser rangefinder. Quick Surround View mode allows you to get a fast, programmable 360-degree panoramic view. It can reportedly be completed by the OMS-110 system in less than three seconds.

Airbus Defense and Security has developed the OMS-200 low profile optocoupler mast, either as an addition to the OMS-110 or as a stand-alone solution. This mast, shown at Defense Security and Equipment International 2013 in London, features improved stealth technology and a compact design. The OMS-200 modular, compact, low-profile, non-penetrating command/search optocoupler mast integrates various sensors into a single housing with a radio-absorbing coating. As a "replacement" for the traditional direct-view periscope, the OMS-200 system is specifically designed to maintain stealth in the visible, infrared and radar spectrums. The OMS-200 optocoupler mast combines three sensors, a high-definition camera, a short-wave thermal imager and an eye-safe laser rangefinder. Image from high quality and high resolution from a short-wave thermal imager can be complemented by an image from a medium-wave thermal imager, especially in poor visibility conditions, such as fog or haze. According to the company, the OMS-200 system can combine images into one picture with excellent stabilization.

SERIES 30

At the Euronaval 2014 in Paris, Sagem announced that it has been selected by the South Korean shipyard Daewoo Shipbuilding and Marine Engineering (DSME) to supply non-penetrating photocoupler masts for the equipment of the new South Korean diesel-electric submarines of the "Son-Won-II" class, for which DSME is the lead contractor. This contract marks the export success of Sagem's latest family of Search Optronic Mast (SOM) Series 30 optocoupler masts. This non-hull-penetrating search optronic mast can simultaneously receive more than four advanced electro-optical channels and a full complement of electronic warfare and Global Positioning System (GPS) antennas; Everything fits in a lightweight sensory container. The Series 30 SOM optronic mast sensors include a high-resolution thermal imager, a high-definition camera, a low-light camera and an eye-safe laser rangefinder. The mast can accept a GPS antenna, an early warning avionics antenna, a direction finding avionics antenna and a communications antenna. Among the operating modes of the system there is a fast all-round viewing mode, with all channels available at the same time. Dual screen digital displays have an intuitive graphical interface.

Sagem has already supplied the Series 30 SOM variant to the French Navy's new Barracuda-class diesel-electric submarines, while another variant has been sold to an as yet unnamed foreign customer. According to Sagem, the Series 30 SOM mast supplied to the South Korean fleet will also include a signals intelligence antenna, as well as optical communications equipment operating in the infrared range. A command variant of the Series 30 SOM, designated Series 30 AOM, is also available; it features a low profile mast and is fully compatible with the Series 30 SOM variant in terms of mechanical, electronic and software interfaces. The same container and cables can be used for both sensor units, allowing fleets to select the optimal configuration for specific applications. The basic set includes a high-resolution thermal imager, a high-resolution television camera, optionally an eye-safe laser rangefinder, a short-wave thermal imager and a day/night backup camera.

Pilkington Optronics' origins date back to 1917, when its predecessor became the sole supplier to the British Navy. At one time, this company (now part of the Tales company) began proactively developing the CM010 family of optocoupler masts, installing a prototype in 1996 on the British Navy nuclear submarine Trafalgar, after which in 2000 it was selected by BAE Systems to equip new Astute class nuclear submarines. The CM010 twin photocoupler mast was installed on the first three boats. Tales subsequently received contracts to equip the remaining four submarines of the class with CM010 masts in a twin configuration.

The CM010 mast includes a high-definition camera and thermal imager, while the CM011 has a high-definition camera and an image enhancement camera for underwater surveillance, which is not possible with a traditional thermal imager. In accordance with the contract received in 2004, Tales began supplying CM010 masts to the Japanese company Mitsubishi Electric Corporation in May 2007 for installation on the new Japanese diesel-electric submarines “Soryu”. Tales is currently developing a low-profile variant of the CM010 with the same functionality, as well as a sensor package consisting of a high-definition camera, a thermal imager and a low-light camera (or rangefinder). This sensor kit is intended to be used for special tasks or diesel-electric submarines of smaller dimensions. The low-profile ULPV (Ultra-Low Profle Variant), designed for installation on high-tech platforms, is a unit of two sensors (a high-definition camera plus a thermal imager or a camera for low light levels) installed in a low-profile sensor head. Its visual signature is similar to that of a commander's periscope with a diameter of up to 90 mm, but the system is stabilized and has electronic support.

Panoramic mast

The US Navy, the largest operator of modern submarines, is developing periscope technology as part of its Afordable Modular Panoramic Photonics Mast (AMPPM) program. The AMPPM program began in 2009, and as defined by the Office of Naval Research, which oversees the program, its goal is “to develop a new sensor mast for submarines that has high-quality sensors for panoramic search in the visible and infrared spectra, as well as short-wave infrared and hyperspectral sensors for long-range detection and identification.” According to the Office, the AMPPM program should significantly reduce production and maintenance costs through modular design and a fixed bearing. In addition, a significant increase in availability is expected compared to current optocoupler masts. In June 2011, a prototype mast developed by Panavision was selected by the Authority to implement the AMPPM program. First there will be at least two years of testing on land. This will be followed by testing at sea, which is scheduled to begin in 2018. New AMPPM fixed masts with 360-degree visibility will be installed on Virginia-class nuclear submarines.

Russian analogue of Periscope The social network OK.ru promised to launch at the end of April, however, the application became available to the general public 2 months later. In my opinion, in general, the product was a success, although there is no need to talk about the uniqueness of the product - OK Live– a real clone, only tailored for the Odnoklassniki social network and equipped with a couple additional functions, which, to be fair, Periscope lacks.

There are very few broadcasts today. In the evening there were only 2 people online! Those. getting to the top is guaranteed! However, this won't last long...

Cons of OK Live

What I was least pleased with about the app was the heart system, or rather their graphical design. In the periscope, each viewer receives “his own color” and throughout the broadcast, the hearts he places are colored according to the color received. At OK Live everything is different. By tapping on the screen and setting classes, many multi-colored figures fly out, differing from each other in their shape. And everything would be fine, but these masterpieces take up much more space than on Periscope, hiding much more of the picture than we would like. Fortunately, it is possible to turn off everything, but I’ll talk about this when we talk about the advantages.

I was also a little disappointed by the broadcast map - it was simply ripped off and copied from Periscope 1 to 1. For some reason I was hoping to see a Yandex map, but not Google (because the product was jokingly positioned as “import substitution”), which it doesn’t smell like.

The ability to rewind broadcasts was also disappointing. No matter how I tried, I couldn’t rewind the recording. Either watch the entire recording from the very beginning, or go through the forest. Perhaps this is a glitch and in the future the developers will fix everything, but for now they won’t be able to rewind ((

Pros of OK Live

1st plus– the ability to disable the display of chat and likes while watching a live broadcast. Indeed, Periscope clearly lacks such a thing. Very often phrases cover exactly this part of the frame that you want to look at.

2nd plus– the ability to conduct live broadcasts both on your own behalf and on behalf of groups in Ok.ru of which you are an administrator.

3. I also can’t help but mention the function of turning on the phone’s LED flash in flashlight mode. This is a very useful thing when shooting in the dark.

4. The author of a broadcast in OK Live can apply all sorts of filters, similar to those built into Instagram or Snapster. With their help, a video blogger is able to “ennoble” the picture and make it more attractive.

5. Stability of operation. During the tests, the application never froze or slowed down. The broadcasts loaded very quickly. Perhaps the reason is that OK Liv only and the load on the servers, due to the small number of broadcasts, is not loaded, but the fact remains that so far everything is stable and without glitches.

General impression

If you do not take into account the fact that the application is 95% similar to Periscope, the product was a success. I hope that OK Live can conquer at least half of the Russian market.

Periscope- a program that allows you to conveniently conduct online broadcasts in real time via the Internet. Users can view private and public broadcasts, and can like and comment on videos. You will also be able to conduct such video broadcasts yourself and communicate with the audience.

Periscope has grown significantly and this is evidenced by the installation statistics of this application: over 70,000,000 users have already installed and are using the application. The quality of performance is excellent, the video is transmitted perfectly and without delays. Even if you have weak internet. The social network Periscope will allow you to broadcast your video and communicate with viewers in live. You can also subscribe to people you are interested in and watch their lives and watch their broadcasts in real time (or you can watch a recorded video). With Periscope you can spy on the whole world, because video broadcasts take place all over the globe, and you can see what a French girl is doing, how the guys live in Canada, you will see real mountains, you can hear the sound of the ocean and much more.

The interface consists of three tabs: the first one displays ongoing broadcasts; The 2nd shows a map with video broadcasts; The 3rd displays a list of recommendations and most popular videos. Today Periscope has no analogues, so it is certainly the leader in the market.

Key features of Periscope on Android:

With the development of web technologies, a huge number of new applications, sites and games appear. Over the past few years, narrowly targeted social networks (Twitter, Instagram, YouTube and others) have become very popular. Among Internet users, the question of the history of the creation of a fundamentally new social network Periscope.

Who created the periscope

Many users of the service know nothing about who invented the periscope and why this application gathered such a large audience in just a matter of months. In 2014, two friends, Kayvon Bikpour and Joe Bernstein, came up with an idea for a new startup: creating a separate service for streaming video in real time from anywhere. globe.

According to the developers themselves, Bikpour was the main creator of Periscope, who thought through the operating principle and future functionality. After drawing up a detailed work plan, the friends developed software part project, at this stage the main developer of the periscope was Bernstein. The beta version of the program was released in February 2014. At first the project was called Bounty. Thanks to the large-scale advertising campaign, the number of users of the new social network began to grow rapidly and already in April 2014 the service brought its creators $1.5 million in income. However, over time, users began to complain about frequent bugs in the work of Periscope and the lack of quality content.

In January 2015, the owners of the social network Twitter bought the concept and all rights to the Bounty service and renamed it Periscope. Thanks to active promotion on Twitter, Periscope gained even more popularity. The developers temporarily stopped the service to fix existing problems, and already in March 2015, a test version of the application was launched and became available. Two months later, the application was released for devices running on the Android platform.

In August 2015, the official Periscope service Twitter account announced that the number of application users had exceeded 10 million users. This result in the influx of users is a record since the creation of the Snapchat application (a program for instantly sharing photos and video files with selected accounts; in just 5 months of operation, the application’s audience totaled 50 million users).

Application Features

• the ability to log into Periscope without creating a new account. Your existing Twitter account is used;
• search for broadcasts that are live around the globe. The application contains a built-in map of the globe, which shows both active and completed user broadcasts;
• Each user can create personal broadcasts. Completed broadcasts are stored in your profile for only 24 hours; after 24 hours, all videos are permanently deleted. If you want to save broadcasts, the program offers the function of downloading videos to the device gallery.

Periscope analogues

YouTube. The popular video hosting is an analogue of Periscope. On YouTube, you can not only watch and download videos, but also create live broadcasts. However, a large number of Users are finding it difficult to download additional software for video streaming. Users can also create ones that have a webcam. In Periscope, you can create live broadcasts directly from your smartphone, no additional software no need to download.

Meerkat is a periscope-like application that is also designed for video streaming, but Meerkat is only available for Android OS users.

Periscope – discover the whole world

Periscope gained enormous popularity between June and November 2015. Thanks to the huge number of broadcasts, you have every chance to see the events of the desired point on the globe at any second. The creators of Periscope are improving the application and eliminating existing inaccuracies. A report on their activities can be found on the service’s official Twitter page https://twitter.com/periscopecope.
