Is a term usually associated with interactive media technology, such as the Internet and video games

Interactive media refers to digital media that depends on the customer’s participation. This digital media is usually a mixture of computerised elements such as moving graphics, digital text and sound. In our technology driven world interactive media surrounds everything we do. If you unlock your phone interactive media is likely to be the first thing you see on your screen. Your go-to gaming app is the perfect example of interactive media at your fingertips – app developers combine exciting moving images with digital environments and complementary backing tracks to provide a captivating interactive experience.

Virtual reality

Virtual reality is an ever-expanding branch of interactive media with big brands like Oculus meeting the demand for virtual reality systems by producing cutting-edge VR headsets. Virtual reality developers and designers build intricate fictional 3D computerised environments that reflect reality. When you put on a virtual reality headset or special VR gloves you are transported to a life-like virtual world where you are able to pick up objects that exist only in the virtual space.

Virtual reality development can be a time-consuming process as developers create VR specific user interfaces which allow interaction in the programme. However it has several useful applications such as immersive gaming and films, vocational training and education.

Apps

Apps are short for ‘applications’ and are programmes that can be purchased for your portable device whether you have an iPhone or an android phone – these can be free or cost up to a few pounds. There are apps for almost everything – from apps that monitor the way you sleep to apps that help you discover new cities.

According to TechCrunch there are 2.6 billion smartphone users worldwide and this number of mobile users is set to nearly triple by 2020. As a result app development is now a booming business, with new app start-ups being created almost every day. Consumers now have so much choice when it comes to which app to opt for, a clear and engaging app design with the most engaging content, and attention to user experience is more important than ever.

Websites

Most people use several websites every day. Your website design is likely to be the first indication of what your business does and why, so it’s important to get this right.

One way to encourage someone to stick around on your website for longer is to make it interactive. Interactive websites can include video, animation and sound to heighten engagement by providing an experience that plays on the senses. The best website design is not merely interactive but also makes relevant information easily accessible to the reader.

  • Training videos

    Training videos are videos used by companies to provide situational demonstrations in an interactive space to train staff in the company’s practices. These training videos are often accessible on the company’s e-learning platform.

    Multimedia for events

    Event technology could mean touchscreen monitors, virtual reality, motion sensor lights or iPads that are incorporated into an event space. Interactive screens are a great way to encourage visitors to engage at an exhibition or event by effectively presenting the company’s product rather than delivering a heavy sales pitch.

    Streaming media is video or audio content sent in compressed form over the internet and played immediately over a user's device, rather than being saved to the device hard drive or solid-state drive. During the streaming process, the media file that's played on the user's device is retrieved from a remote location and transmitted continuously over the internet using a wired or wireless connection.

    Streaming explained

    With streaming media, a user does not have to download an entire audio or video file to play it. Instead, the file is sent in a continuous stream of data to the user's device so it can play as it arrives in real time or near real time. The user can also pause, rewind or fast-forward the file, just as they could with a downloaded file, unless the content is being streamed live, in which case the user can only watch or possibly participate in the event.

    Depending on the streaming service, a user may be able to stream and consume different kinds of media, including the following:

    • music
    • videos
    • movies
    • TV shows
    • podcasts

    How streaming works

    Streaming files -- audio, video and others -- are stored on a server somewhere on the World Wide Web (WWW). When a user requests the file, it gets transmitted over the web as sequential packets of data that are streamed instantly. Since streaming data is broken down into data packets, its transmission is similar to that of other types of data sent over the internet.

    The file is played within a browser on the client's device. An audio or video player hosted by the browser accepts the flow of data packets from the streaming service's remote server and interprets them as video or audio, then plays the media for the user. Unlike traditional media systems where files are downloaded and stored on the device, streaming media files are deleted automatically once the user ends the streaming.

    Some streaming services rely on User Datagram Protocol (UDP) to stream their content, while others use Transmission Control Protocol (TCP). Both UDP and TCP are transport protocols used to move data packets across networks. TCP opens a dedicated connection before transmitting data, which makes it a more reliable protocol than UDP. However, TCP also takes longer to transmit data compared to UDP. TCP and UDP are both used with the Internet Protocol (IP).

    Most streaming services use content delivery networks (CDNs) to store content in locations that are closer to users. Such proximity reduces streaming latency, speeds up content delivery and reduces buffering.

    Streaming requirements

    Streaming usually requires a reliable, high-speed internet connection because the media files must be retrieved from a remote location and then delivered to a user's local system with minimal lag or latency (delay). A slow connection decreases the speed at which the content is delivered, affecting the user's streaming experience.

    Users must sign up with a streaming service to access and view media files on their local machines. They must also have a compatible display device with a resolution that's high enough to support incoming streaming video and a speaker that can play incoming streaming sound with adequate fidelity and clarity.

    The receiving system must also include a media player to play the streaming content. The player can be part of a browser, a plugin, a separate program or a dedicated device.

    Streaming services and over-the-top platforms

    There are many streaming services that offer different kinds of streaming content, such as movies, TV shows, music and podcasts. Some examples of well-known internationally available streaming services include the following:

    • Netflix
    • Amazon Prime
    • Hulu
    • Disney+
    • ESPN+
    • Apple TV+

    These service providers are also known as over-the-top (OTT) platforms. OTT simply means TV and film content watched via a streaming service instead of through a cable or satellite television provider. OTT includes services such as Netflix and Hulu, as well as providers that offer live streams with niche content like sports, lifestyle, music or cartoons.

    Streaming vs. downloading

    One of the fundamental differences between streaming and downloading is the way media files are saved and used. In streaming, the browser plays the video without creating a local copy or saving the file in the receiving device's memory or storage system. The video loads a little bit at a time and plays it back in real time or near real time.

    In contrast, with downloading, a copy of the entire file is saved locally in the device's solid-state drive or hard disk. The file cannot be played until the entire file has been downloaded and is available to the media player software. As more files are downloaded, they take up considerable storage space and may eventually affect the device's performance. Storage issues are avoided with streaming. Furthermore, the performance of the streamed media file does not depend on the device memory. It is only affected by the user's internet speed (assuming they have a streaming-compatible device that adequately supports streaming sound and video).

    Unlike downloaded files, streaming files are subject to buffering. Buffering is a process by which the streaming media preloads a few seconds of the stream into a memory buffer so that the file continues playing smoothly even if the internet connection is interrupted. On slower connections, a video can take a long time to buffer, affecting the user's streaming experience. That's why a reliable, high-speed internet connection is preferred when consuming streaming media. Downloaded files play locally so they don't require an internet connection and are not subject to buffering delays.

    Advantages of streaming media

    Streaming media offers multiple advantages over downloaded files. For example, with streaming, users can enjoy a vast variety of content and watch (or listen to) it on demand. They can also take advantage of interactive features like video search and personalized playlists to customize and enhance their streaming experience.

    Streaming services -- also known as content deliverers -- can monitor the types of content visitors are consuming and, based on that information, the services may provide recommendations to further improve user experiences.

    In addition, content creators retain greater control over their content (intellectual property) because the files are not stored on viewers' computers. Instead, the file is automatically removed once it has been consumed. In this way, a user gets to enjoy the content of their choice while the rights of the content creator are protected.

    Live streaming

    Streaming media is usually delivered over the internet using prerecorded files. However, it can also be distributed as a live broadcast feed. For live streaming, the video signal is converted into a compressed digital signal and transmitted from a web server as multicast, sending a single file to multiple users simultaneously and in real time.

    Many streaming content providers organize live streaming events. Some social media platforms, such as Facebook, YouTube and LinkedIn, also offer occasional live streaming events.

    Users can watch a livestream on any compatible device with a fast internet connection such as the following:

    • laptop
    • desktop
    • smartphone
    • tablet
    • smart TV

    Depending on the streaming platform, users can watch a variety of live stream programming, including the following:

    • music shows
    • cooking demonstrations
    • business workshops
    • technology workshops
    • sports events
    • video games
    • awards shows
    • special one-time events

    Factors affecting streaming performance

    Numerous factors can affect the performance of streaming media. On the network side, the two primary factors are latency and network congestion. Network latency or lag refers to the delays in communication over the network. It affects the speed at which content is delivered to users. Network congestion occurs when too much data is sent through a network, resulting in connection timeouts and packet losses at the client's destination.

    On the user side, the three key factors affecting streaming performance are internet connectivity, device compatibility and available bandwidth. An unstable internet connection, perhaps due to Wi-Fi problems, results in interrupted streaming and a poor user experience. Restarting the local Wi-Fi router may stabilize the connection and improve streaming performance. A low-bandwidth internet connection also hampers streaming performance, which is why streaming content is best played on high-speed Wi-Fi or other networks, instead of over mobile networks which tend to be slower for video, live streams and some other kinds of streaming media.

    Certain media files such as video may require a relatively high amount of processing power from the client device. An older device or a slow-performing device running multiple concurrent processes can affect performance.

    Pseudo-streaming

    Pseudo-streaming, also known as progressive downloading, is a hybrid approach pairing conventional downloading and streaming. The method is easier to implement than full streaming because it doesn't work in real time. Instead, a large chunk of the media file is downloaded into the web browser's cache. The browser then plays it simultaneously.

    With a pseudo-streamed file, users cannot skip forward but must wait for the file to be downloaded until that point. Unlike streaming, the file remains in the browser cache and isn't automatically deleted.

    In the past, browsers used Macromedia Flash files for progressive downloading. These files were served from a conventional web server and played on a Flash plugin installed on the user's browser. Modern browsers that use HTML5 can pseudo-stream files without using Flash.
