Video: Machines’ Lens on the World

Machines’ Lens on the World

Be it entertainment, video chat, live streaming, conferencing, surveillance, or intelligent manufacturing, video is now ubiquitous. It is increasingly the essential ingredient, the secret sauce that brings people together. Video is intuitive, convenient, and informative. It has become the preferred medium of information delivery, alongside text and image, and is helping to reshape the world in a variety of ways.

People look for security and efficiency from video surveillance, they like to interact through video communications, and, more and more, they seek an immersive ultra-HD experience via entertainment video. All of these require a network that is cloud-based, integrated, open, and that has high bandwidth and low latency. As an important enabler of enterprises’ digital transformation, video is evolving from a basic service of businesses to a fundamental capability.

Video reshapes the world

Video changes the way we produce, making production more efficient and more secure

In Industry 4.0, robotic arms and robots that can view and respond to their environments make automatic, intelligent, and flexible manufacturing possible. In industries with high security requirements, such as in petroleum and petrochemical, cameras are extensively deployed at locations such as oil fields, factories, drilling platforms, and pipelines. This is with the aim of identifying and flagging potential security vulnerabilities in real time. When machines can view and respond to their environment in this way, production and operations become more efficient and secure.

Video changes the way we communicate, enabling face-to-face interaction from long distances

Video is everywhere, including on mobile phones and tablets, computers and televisions. Video is making communications more efficient and affordable for individuals and businesses. New technologies, such as holographic delivery, make videos much more expressive, enabling people to interact face-to-face despite being separated by long distances. For example, Professor Stephen Hawking once beamed a live hologram of himself to the Sydney Opera House, speaking to the audience about his thoughts on technology, the universe, and life. The potential of the technology is clear for education, for business, and for entertainment.

Video changes the way we entertain, creating superior user experiences

Today's entertainment videos are rich in content and form, raising expectations for a premium video experience, such as with 4K ultra-HD video. We live in a mobile era with a fast-growing live streaming industry. People increasingly create and watch live videos on their mobile phones. Live streaming applications introduced by Internet giants such as Facebook, Google, and Twitter have fueled this trend. Also part of this trend are new technologies such as augmented reality (AR) and virtual reality (VR), which are regularly applied in live streaming as well as in games, films, and other areas. These developments are bringing a more immersive and interactive experience to users.

Enterprises set sights on the video trend

Data from MarketsandMarkets1 shows that the global video surveillance market is set to reach around US$75.6 billion by 2022, with a compound annual growth rate (CAGR) of 15.4% between 2017 and 2022. In terms of the video communications market, using video conferencing as an example, the global market for video conferencing is forecast to expand at a CAGR of 8.5% from 2016 to reach US$7.85 billion by 2023, according to Transparency Market Research2. For entertainment video, taking video-on-demand (VOD) as an example, Transparency Market Research forecasts3 that the global VoD market will expand at a CAGR of 9.3% from 2016 to reach US$73.9 billion by 2024.

Amid this explosion in video innovation, many enterprises are setting their sights on developing video as a key productive force to support their digital transformation. In healthcare, for example, video can be used to support medical services delivered to remote communities where there is a scarcity of local know-how or a complete lack of resources. Elsewhere, insurers are applying video to remote damage assessment for road accidents, thereby expediting assessment-to-repair process, as well as claims. Such applications also reduce labor costs and save time. In telecommunications, carriers are offering IPTV-based HD TV video chat services to connect children of migrant workers with their parents, and senior citizens with their families.

Yet, while trendy, video is very data-heavy. Its data requirements are far greater than those of audio and text. This is placing growing pressure on network bandwidth and analytics capabilities. Enterprises therefore need more intelligent video processing systems, as well as access to larger broadband capacity. Efforts across the entire video ecosystem are required to make this a reality.

Video surveillance: from "seeing" to "seeing clearly" and "understanding"

From factory production to city management and emergency communications, video surveillance enhances efficiency and security. It also facilitates informed decision-making, which is why so many state and city governments around the world use them.

In today's ecosystem, "seeing" is no longer sufficient for intelligent video surveillance. It is now about "seeing clearly" and then "understanding". Seeing clearly means cameras have to guarantee 4K or even higher quality in all conditions. Enabling "understanding" requires cloud-based platforms built on intelligent and connected networks capable of sharing and analyzing massive amounts of data and extracting their true value.

Where there are opportunities, challenges follow

  • How to tap latent network intelligence to generate better analysis and interaction

Most current video surveillance systems can only analyze video data around one location or within a very limited area. The systems are generally unable to intelligently interact with data from surrounding devices to broaden the coverage and analysis. Their front-end devices typically have to send the original video data to a back-end computing center for analysis. This takes up network resources, affects analysis efficiency, puts pressure on the computing center, and impedes the center's big data and data mining capabilities.

  • How to connect platforms so that data can be easily shared

Traditional video surveillance systems tend to be built in silos by different industries and departments, with manufacturers using a wide range of standards and types of architecture. The massive amount of video data is stored in separate data servers. All of this results in repetitive system construction. Connecting platforms becomes harder, while making it tougher to combine and share video data fast enough to support timely and informed decision-making that requires inter-departmental collaboration.

  • How to flexibly allocate resources via cloud-based video surveillance systems to quickly roll out new services

With the rapid expansion of enterprises and urbanization, traditional video surveillance systems can no longer keep up with the changing needs. Cloud deployment is vital to ensuring flexible allocation of computing, storage, and network resources to handle massive volumes of data. This, in turn, opens up capacity for new services, features, and businesses to be rolled out.

  • How to ensure data security

The security of video surveillance systems is a concern as the threat of cyber-attacks and viruses grows. As networks become more connected, an attack at any point can impact the entire network. At critical moments, if the video surveillance system fails and data loss or damage occurs, the compromised functionality could render the investment worthless or close to it. There can also be data privacy implications.

A multi-tiered approach to building intelligent video surveillance infrastructure for security

  • Deploy video cloud to distribute intelligence across the network – from front-end devices, to network edge, to cloud center. Put in place ultra-HD front cameras that have a wide range of sensing and pre-processing capabilities, so that the cloud center can focus on big data analytics and data mining to rapidly find valuable insights that support timely and effective decision-making.
  • Connect different video surveillance platforms to one network in order to maximize the value of video data. To do so, it is important to unify industry standards and use multi-protocol gateways to enable cross-sector connections (such as those of public security, transport, and tourism), making it possible to rapidly retrieve related video data.
  • Build cloud-based video platforms and optimize the network architecture to satisfy changing usage needs. This is with the aim to flexibly allocate computing, storage, and network resources, while also enabling rapid capacity expansion and roll-out of new services.
  • Increase investment in the security of video surveillance and put in place a holistic protection program that covers cloud, networks, and devices to secure the system, data, and personal privacy.
  • Combine resources with other parts of the ecosystem to bring in cutting-edge algorithms and develop general-purpose systems and uniform standards. This is to accelerate integration of third-party applications to support the evolution and innovation of verticals.

Video communications: face-to-face chat anytime, anywhere

Wide usage of video communications across all industries has transformed the role of enterprise communications systems, moving them from a supporting role to one that guides production. Video communications is now a must-have capability for enterprise management, production, and business processes. Having such capabilities allows companies to benefit from significantly lower communications costs, as well as improved operating efficiency and productivity. The rapid development of real-time communications video has helped accelerate the digital transformation of industries including healthcare, education, tourism, finance, and others.

Where there are opportunities, there are also challenges

  • How to ensure a premium video experience on any device in any scenario

Real-time video communications services should provide users with a simple and smooth experience whether users are using mobile phones, tablets, computers or televisions, and whether users are at home, in the office or on the go. The user interface needs to be intuitive and friendly. But devices vary in terms of network interface and line-quality varies too, meaning that poor and inconsistent performance can deter users from trying out new services.

  • How to boost connectivity and interactivity to make video more accessible

At present, there is no uniform standard for the interoperability of video services. Different video communications services use different media signals and protocols, resulting in silos and fragmentation. It also increases development costs, impedes new application development, and negatively affects user experience.

  • How to help video service innovation and vertical development

It is difficult, if not impossible, to win user loyalty and achieve broader commercialization if enterprises rely on video communications alone. It is important to build core video capabilities into premium video services that users can really experience. But fragmented traditional industry chains are generally not open, which makes it difficult to bring together all the required resources. This in turn leads to higher costs and lower development efficiency.

A three-pronged approach
