Cloud Video Platform and Cloud Video Streaming: A Guide for Modern Media

In today’s digital world when everything is available online, cloud streaming and cloud video platforms have truly revolutionized how we consume media content in our comfort. Have you ever given a second thought to how you are able to binge-watch your favorite TV shows and web series on Netflix, stream live broadcasts on YouTube, or participate in a Zoom meeting? It’s all thanks to these two tech innovations, cloud streaming, and cloud video platform.

What is Cloud Streaming?

Cloud streaming, in the simplest terms, is a way to access and use data—like music, videos, or games—straight from the internet, or “the cloud,” without having to download the data onto your device first. Imagine watching television: you switch it on, pick a channel, and your chosen show or movie begins instantly. There’s no need to download the entire program before you start watching; it streams live. Cloud video streaming operates on the same principle and uses the internet for streaming, instead of a cable or antenna signal.

Music streaming: When you listen to songs and music on apps like Spotify or YouTube Music, you’re utilizing cloud streaming. You select a song and it begins playing immediately, as it streams directly from the cloud. The complete song doesn’t need to be downloaded before the music begins.

Video streaming: Services like Netflix, Prime Video, and YouTube all rely on video streaming. You click a movie or video and it begins instantly, thanks to streaming from the internet.

Game streaming: Cloud streaming isn’t just for music and video. Some gaming services, like Google Stadia, use cloud streaming. The game is hosted on a high-powered computer in the cloud, and your gameplay is streamed to your device. This means even less powerful devices can handle high-end games.

History of cloud video streaming

The late 1990s – Early 2000s: Initial years of video streaming – In the late 90s, video streaming began with the launch of platforms such as Windows Media Player and RealPlayer. At that time, the video quality was pretty low and viewers had to download the content before watching, resulting in a poor user experience.

2005 – 2007: Birth of video streaming platforms – The viewing experience somewhat changed with the launch of YouTube in 2005. YouTube was able to stream videos directly in the web browser using Adobe Flash Player, which significantly improved the streaming experience.

In 2007, Netflix launched its online streaming service and made a big move towards cloud video streaming. Interestingly, it originally started as a DVD-by-mail service. Now, the content was stored and processed in the cloud and streamed to users via the internet.

The 2010s: Rise of cloud computing and video streaming services – Around 2010, there was rapid advancement in internet speeds and cloud computing, making the way towards cloud streaming narrow. At this time, Netflix migrated to Amazon Web Services (AWS), which nearly took 7 years. This allowed rapid growth and scaling, offering a seamless viewing experience to a large number of subscribers.

“As per Pew Research, the total video streams saw significant year-over-year growth, up 31.5% to 14.5 billion streams in 2010 compared to 2009. Similarly, Wall Street Journal reported Netflix as the top paid streaming video service in the last quarter of 2010.”

2015 – Present: Global adoption and innovation – Today cloud streaming is a dominating force in the media landscape. High-speed internet, technological advancement, and the availability of smart devices had made HD cloud streaming available to a larger global audience.

“Streaming accounts for 80% of the global music market, compared to 7% in 2010. The video streaming market size is expected to grow at a CAGR of 21% from 2021 to 2028. – ‘Recording Industry Association of America.’”

How does cloud video streaming work?

Video Production and Upload – The video is first captured or recorded. It is then uploaded to a video hosting platform like VdoCipher to be prepared for streaming.

Video Encoding (Transcoding) – The next step is to encode the video into a format that is suitable for streaming. In this process known as video transcoding, the video is compressed in size while maintaining quality. Most cloud streaming platforms use H.264 or H.265 video codec for transcoding while the audio is encoded using the AAC codec.

Adaptive Bitrate Streaming – The encoded video is divided into small segments, typically 2-10 seconds long. These segments are encoded at different bitrates to create different quality levels. This process is known as Adaptive Bitrate Streaming which ensures dynamic adjusting of the video quality as per the viewer’s network connectivity.

CDN Delivery – The video segments are stored on a Content Delivery Network (CDN), a global network of servers. When a user makes a playback request, it is streamed from the nearest CDN server, reducing latency and ensuring fast delivery.

Video Playback – The viewer’s device makes a video playback request from the CDN to watch a video. The device’s video player downloads the video segments and decodes them to assemble as a continuous stream.

Digital Rights Management (DRM) – To protect copyrighted content and prevent piracy, cloud video streaming platforms like VdoCipher use Digital Rights Management (DRM) encryption. The content is encrypted via a private key mechanism and only authorized devices receive the decryption key via a secure license server.

VdoCipher DRM security in cloud video streaming

As more and more content is hosted and streamed via the cloud, the security of video content has become paramount. This is where DRM comes into play.

DRM or Digital Rights Management is a set of techniques for copyright protection of digital assets. When we talk of videos, DRM ensures only authorized access and distribution of video content and restricts how the users’ access and copy the purchased content. DRM protects video content from piracy and protects the revenue stream for creators and businesses.

Consider this: You are a content creator or streaming platform and have invested much of your resources and time in creating or acquiring video content. Without secure DRM measures in place, your videos can be easily downloaded or shared, leading to substantial revenue loss. This is not something any business or creator wants. The ease with which video content is copied and illegally distributed with the widespread availability of the internet, DRM has become a necessity for cloud video streaming.

“Vdocipher, a secure video hosting and streaming service offers Multi-DRM Encryption using Google Widevine and Apple FairPlay DRM’s. Videos streamed via VdoCipher cannot be illegally downloaded or shared using any internet plugin or software.

More than 3000 e-learning and media businesses from over 120 countries rely on VdoCipher for hosting and securing their premium content.”

Choosing the right Codec and Format for cloud video streaming

When it comes to cloud video streaming, one of the crucial decisions is selecting the appropriate codec and format. This choice can significantly influence the quality of your streams, the compatibility with various devices, and even the cost of your operations. Let’s simplify these technical aspects and understand what they mean.

It encodes (compresses) your videos for streaming and then decodes (decompresses) them on the viewer’s device. The codec’s work is crucial as it determines how well your video streams over the internet and how good it looks when it arrives at its destination.

H.264 (AVC) and H.265 (HEVC) are the most popular used in cloud video streaming because of their efficiency and broad compatibility.

H.264 offers a balance of compression and quality, making it a safe choice for most streaming scenarios. Compared to H.264, H.265 offers superior compression. It further reduces the bandwidth usage and costs, but requires more processing power and isn’t as widely supported as H.264.

While the codec handles the compression and decompression of your video, the format (or container) is like the video’s suitcase. It packages your video, audio, and other related data (like subtitles and metadata) together for transportation.

The most common formats for cloud video streaming are MP4 and HLS. MP4 is widely compatible and supports a variety of codecs, making it a flexible and reliable choice. HLS (HTTP Live Streaming) is a streaming protocol developed by Apple that is excellent for live streaming because it divides the video into small segments and allows for adaptive bitrate streaming, enhancing the viewer’s experience.

Ultimately, the best combination of codec and format for cloud video streaming will depend on your specific needs. If you’re targeting a broad audience with diverse devices and internet connections, H.264 with MP4 or HLS might be your best bet due to its wide compatibility and balance between quality and compression.

If you’re focusing on viewers with high-speed internet and modern devices, or if minimizing bandwidth usage is a priority, using H.265 with HLS could be the more beneficial option.

Role of CDN in cloud video streaming

When discussing cloud video streaming, one term that you’re likely to encounter frequently is CDN or Content Delivery Network. It has a significant role in delivering a smooth streaming experience to viewers worldwide. CDN is a geographically distributed network of servers. When a viewer clicks on a video, the CDN delivers the video data from the server that is closest to the viewer.

There are reasons why CDNs are vital in the realm of cloud video streaming.

1. Reduced Latency: When your viewers are spread across different regions, the distance between your video data and the viewers can lead to delays, known as latency, in video loading and playback. A CDN drastically reduces this latency by storing copies of your videos on multiple servers worldwide and delivering content from the server nearest to each viewer.

2. Improved Load Balancing: Imagine a new episode of a popular show being released on a streaming platform. The sudden surge in viewers can put a lot of strain on a single server, leading to slower streaming or even crashes. CDNs can manage this load by distributing the traffic across several servers, ensuring a smooth viewing experience for all viewers, no matter how many there are.

3. Enhanced Viewer Experience: By reducing latency and handling high traffic loads, a CDN ensures your viewers enjoy a buffer-free, high-quality streaming experience. Whether watching live sports or a web series, viewers enjoy the content without interruptions and delays.

4. Protection Against Attacks: CDNs also provide an extra layer of security by mitigating Distributed Denial of Service (DDoS) attacks. By distributing the traffic across multiple servers, a CDN can help prevent an overload on any single point. This makes it harder for such attacks to disrupt your service.
