Specifically, the global video cloud streaming platform and service are expected to value $350 billion by 2030. Nearly 85% of US viewers have at least one subscription to a media streaming service. So why is media streaming becoming so popular and profitable?

What are media streaming service?

Media streaming service are online platforms where viewers stream and access multimedia content such as movies, shows, audio, sports, and podcasts over the internet. To access the library of content on these media services, viewers require a subscription or some sort of payment. Viewers need an active internet connection and compatible software and hardware systems to stream the content which can be smartphone, computer, smart TV, media player, and more.

The media files are stored remotely and transmitted in sequential data packets from a server to a client. On the viewer’s device, the media is played immediately while the rest of the file is continuously transmitted a few seconds at a time over the internet. In case of downloading, the entire file is first saved on the device’s hard drive and only played once the download is complete.

Media streaming service have helped people cut the cord on traditional satellite TV subscriptions and cable. They can now watch their favorite piece of content based on their preference, timing, language, and more.

While commuting, cooking, or relaxing, your entertainment is right in your hands. All they need is an internet connection and connected device. There is no more waiting to watch a fixed slot show or movie and from classic entertainment to latest releases, everything is accessible right on your smartphone, tablet, laptop and other smart devices. Most importantly, people only pay for the content they need to watch and there are subscription plans to fit different budgets.

Advantages of media streaming service over traditional viewing

The way we consume video content has drastically shifted from traditional cable and satellite viewing to media streaming services. However, there are key differences between both the popular methods of viewing.

• Flexibility – In a traditional cable connection, you have to watch a movie at a specific time and in case you miss it, you have to wait for the same movie to be aired in future. When we were young,  our whole family gathered at the living room to watch a weekend movie on cable television. With time, the way we consume content has changed. Now you have the flexibility to watch at any time, place, date and what not. You may resume, pause, watch in slots and do everything that adjusts to your busy schedule.
• Content collection – In a typical TV setup, you are limited to a few channels and shows. Basically, everything depends on your cable or satellite provider. Streaming media services on the other hand have an extensive range of content, including shows, movies, documentaries from different providers. You can easily find the content that best suits your preference and interest.
• Cost – With a media streaming service, you have to only pay for the content you want to watch. Some streaming services even offer account sharing, allowing access to the same account with different profiles which further reduces the cost. In cable television, you have to pay a certain amount every month for limited channels.
• Availability – On streaming services, viewers with disabilities, those hard of hearing or deaf can easily watch content with subtitles and closed captioning. Also, there is multilingual content available on these platforms which make content availability to a large audience.

One of the key advantages of media streaming services over traditional viewing is the ability to adapt quickly to changing viewer preferences and trends. By staying informed with the latest streaming stats, providers can tailor their content and delivery methods to meet the demands of their audience more effectively.

Types of media streaming service

On a broader perspective, there are several media streaming services, including:

Video-on-demand services – On VOD platforms, content is delivered over the internet in real time. Viewers watch video content such as movies and shows as per their convenience on a range of supported devices. Viewers usually pay a subscription fee to watch content. Examples include HBO Max, Disney Hotstar, and Netflix.

Live streaming services – live streaming services broadcast real-time events, such as live news, events, concerts and viewers watch them at the same time at which they happen. Some live streaming services allow viewers to engage, comment, and interact with fellow viewers and hosts in real-time. Videos on most streaming platforms like Facebook, Twitter, and Instagram are broadcast live as they happen.

Educational streaming services – These platforms provide educational content, such as instructional videos and online courses. They cover a range of topics and subjects like engineering, technology, physics and anything that educates a learner. They can be free as well as paid or a mix of both. Examples include Khan Academy, edX, and Coursera.

Music streaming services – On these services, users listen to music, create custom playlists and choose from a huge library of music including songs, podcasts, playlists and favorite creators. Some of the features are free while to avail more features like ad-free music and offline download, users need to pay a subscription fee. Spotify, YouTube Music are popular music streaming services.

How does a media streaming service work?

Media streaming services work by continuous transmission of media files from the server to client device in real-time which is known as streaming. The media file playing on the user’s device is actually stored on a remote server. On playback request, the file is transmitted in sequential data packets which are instantly streamed. Without having to download media content on the device, users access and consume media content.

• Content upload – The creators upload the media content such as videos on a video hosting platform or server, where it is stored.
• Encoding – The uploaded media file is converted into digital format to transmit it over the internet in proper format. The process involves transcoding, compression without affecting the video quality and bitrate encoding.
• Delivery – Most media streaming services use Content Delivery Network (CDN) to store content in the proxy servers nearest to the user location. It ensures that the content delivery is fast, latency and buffering free. Upon a playback request, a small chunk of data (first few seconds of media file) start streaming.
• Buffering – As soon as the content is streamed, the streaming media player preloads a few seconds of stream ahead of time to ensure uninterrupted content stream playback.

TCP vs UDP protocols for media streaming

There are two popular transport protocols to transmit data packets over a network, User Datagram Protocol (UDP) and Transmission Control Protocol (TCP).

UDP is a connectionless protocol without any dedicated connection between the sender and receiver device. It is a fast protocol but not reliable as data packets may be lost or arrive out of order and there is no method to retransmit lost packets.

TCP on the other hand establishes a dedicated connection and data flow happens in series. At the receiving device, each data packet is acknowledged and there is a mechanism to retransmit lost packets and ensure correct sequential transmission. This also makes TCP slower but more reliable.

Features to look for in a media streaming server

A media streaming server converts or encodes a media file into a data format and delivers content over the internet across a range of devices. It is dedicated to streaming high-quality media content to clients and comes with added features like codec, broadcast-quality content, adaptive streaming, unflagging reliability, and support for various streaming protocols.

• Streaming protocols – to ensure compatibility across multiple devices and browsers, the media streaming server must support various streaming protocols like DASH and HLS.
• Scalability – capable of handling a large number of simultaneous requests with ease to scale up and down
• Adaptive streaming – media streaming servers adaptive streaming technology dynamically adjust the video quality as per user’s network speed. The bitrates and video quality is automatically adjusted to deliver smooth playback.
• Security – media streaming servers must have robust security measures in place like secure streaming protocols, content protection, security updates, encryption and more.

Technical aspects of media streaming service

Bandwidth – maximum amount of data unit of time that a transmission medium like an internet connection can handle. It is measured in bits per second(bps), Megabits per second(Mbps), or Gigabits per second(Gbps)

Bitrate – the amount of data that is actually transmitted over a network in a given time. Higher the bitrate, higher the video quality but consumes more bandwidth and vice-versa.

Buffering – process of pre-loading data segments while streaming video content. It makes a stream run smoothly as the video is played before the entire video loads. Buffering is good unless that is noticeable due to network issues or bandwidth problems

Latency – time delay between a media stream request and the start of media playback. It is caused by several factors like processing delays and network congestion. Low latency ensures smooth and fast streaming while high latency makes the player wait before the playback starts.

Codec – compression technology with two components, encoder for file compression and decoder to decompress. Codec examples include H.264, H.265, VP9, and AAC

Adaptive bitrate streaming – technique used by many streaming services to adjust the media bitrate to match the available bandwidth. In times of low connectivity and fluctuating bandwidth, the content is streamed uninterrupted and smoothly.

Security issues with media streaming

Video transmission over the internet creates security risks. With millions of users streaming premium content on the web, it’s no surprise that there is a rapid increase in piracy and misuse of content and personal information.

• Unauthorized access and sharing – if some unauthorized person accesses your account or media files, there is risk of data breach and video piracy. There needs to be a mechanism to restrict access. Latest technologies like DRM secure your premium content for unauthorized access, sharing, and copying.
• llegal downloading and streaming – When someone gets access to a media file, in seconds, the content is leaked and made available on the web for free. It is a serious issue faced by the media industry and every year, many economies suffer huge revenue loss.
• Malware attacks – A big security concern in media streaming is injection of malwares and viruses in the streaming media. It can potentially infect a device or system and gain access to the personal files and data.
• Geo-restriction regulations – There are various governing regulations in some countries that restrict certain types of content. There are legal penalties if content is served in those regions. Hence, it’s important to have geo-restriction availability in a media streaming service.
• Credential sharing – A common consumer behavior and revenue loss for streaming providers, credential sharing poses significant security risks. Anyone unauthorized can easily access the media files and no one knows how long the password sharing chain grows. Media streaming providers have a limited number of sign-in users and accounts, restricted password sharing, and OTP-based login.

The main encrypted video streaming protocols in use by most other streaming providers are:

1. HTTP Live Streaming – HLS Encryption with AES-128
2. AES 128 Encryption & Sample AES 128 Encryption.
3. Real Time Messaging Protocol (RTMP) and RTMP Encrypted (RTMPE)

HLS encryption, with AES-128 bit encrypted streaming, is widely marketed as a secure video encryption streaming protocol used for video protection. Indeed, certain security features have been built into these streaming protocols. However, by themselves, HLS Encrypted, DASH, and RTMPE are not sufficient to protect your content. Their security flaws lie in:

• Partial video encryption of streaming content
• Open key exchange mechanism for decryption

Why Only Video Encryption is not good enough?

The video encryption that these protocols offer is not foolproof.

Suppose, you have bought a state-of-the-art lock for your home. One that even the most masterful locksmiths cannot breakthrough. But then, well, you leave your key under the door-mat. Does your state-of-the-art lock still ensure state-of-the-art security for your home?

Many tools are widely available that exploit security vulnerabilities in encrypted streaming protocols. Tools such as IDM, Video Download Helper, and RTPMDump can even download content that has been encrypted, opening the gates for pirates to download and share your content. These tools bypass the video encryption by finding out the key to access the video, without bothering about the video encryption itself.

Although widely used, these streaming protocols are not the only streaming protocols that can be used. VdoCipher uses a modified version of the existing streaming protocols to increase video security, and minimize bandwidth usage.

How VdoCipher’s DRM Based Video Encryption Protects Your Content?

Here we explain how VdoCipher’s Encrypted Video Streaming works, and how our DRM encrypted video streaming technology is hackproof. We explain the complete workflow that our video DRM uses. Steps 5 and 6 of the video streaming workflow are the key differentiators that set us apart from the competition.

B2C or B2B marketplaces also often require features over and beyond video security. VdoCipher fulfills all major requirements for secure video hosting. The complete set of features that VdoCipher offers for enterprise video hosting may be found here.

1. Upload – The video content is uploaded by the registered customer through Desktop, FTP, DropBox, directly from the server, and direct from URL. VdoCipher supports all typical video formats.
2. Transcoding for Protected Streaming – At VdoCipher, we encrypt videos with DRM encryption protocol & multiple bitrates.  Each device (Android, IOS, Desktop) has its own encrypted version of the file. It is in this format that the encrypted streaming takes place in. After the user uploads the video, VdoCipher converts content into an encrypted format. The video is transcoded for optimization at multiple bitrates so that viewers on networks of any quality can conveniently view videos.
3. Storage of Encrypted Content – The videos are stored securely on Amazon’s AWS S3 servers using our own server-side video encryption technology, creating a double layer of protection.
4. DRM Encrypted Video Transfer – Differentiator – Now the encrypted content has to be streamed to the final viewer interface, be it app or browser. Unlike many other media streaming service protocols, there are two key differences: Firstly, the entire stream (not partial) is encrypted using a non-public key whose exchange mechanism is hidden (Via Google Widevine DRM & Apple Fairplay DRM for all platforms). Others like RTMP does it partially and not fully secure. Secondly, the transfer of this encrypted content is not through direct access to the video file. There is a one time URL that is generated and the content is transferred in different chunks to optimize streaming.
5. Licensing & Authentication – Differentiator – If the video has a direct video URL that can be shared, then the encrypted video streaming has completely ineffective security. This is because there can be multiple browser playback of the same video, and therefore the video can be easily downloaded. Our key service differentiator is that we have One Time generated dynamic video URLs. These URLs are accessed only through custom video embed codes, allowing licensing duration for each single video stream. This prevents any URL based sharing.
6. Decryption & Playback – Differentiator – Finally, the encrypted stream content is decrypted inside the player with a dynamic key. Our DRM based key transfer protocol is fundamentally different from the public key transfer protocol in cases of HLS, HTTPS, and RTMPE Encrypted Streaming Protocols. A private key transfer between the website and our API signifies that it is not possible for hackers to decrypt our streams. The One Time video encryption that we use is theoretically and practically hack-proof. We regularly update our authentication mechanism to keep the security features up to date. Video licensing and playback are combined to generate customizable viewer specific watermarks. Within the watermark offering, IP address, Email ID  and User ID can be shown as a light transparent watermark, to identify a playback session by the viewer.
7. Result – Progressive High Secure Adaptive Video Streaming – Through this 6-step Video Hosting, DRM based Video Encryption, and Streaming process, VdoCipher is able to provide a progressive high-security video streaming with future buffer possible. This is also different from RTMP which does not maintain any buffer and can be quite erratic as a result.  Also, once a part of a video is buffered it remains conserved, even when the viewer seeks back or forth. This ensures the fastest loading times and minimal bandwidth usage for secure video streaming.

What Is Video Encryption?

Video encryption is the process of encoding your video so that it can not be accessed by anyone without the encryption key. This stops any unwanted view or even download of the video. This puts a stop to any unwanted view or even download of your videos. 

The videos are encrypted with the help of encoding software and hardware to protect the video content. When a user tries to access the encrypted video. Pirates will get an encrypted file playing via an online video player on their website or app. 

What Is DRM Video Encryption?

Video encryption does a pretty good job to secure videos. Breaking encryption just by brute force might take ages to get access to the video. But there’s a catch even to it, as I mentioned in the beginning, all this encryption would mean nothing if a pirate can easily get access to the encryption key.

This is where DRM comes in, DRM protects the encryption key so that it can not be easily accessed by a malicious user. So, DRM video encryption not only helps in encrypting the video but also protects the encryption key so that a pirate can not access the video via any hack.

Detailed explanation on all VdoCipher security features (DRM encryption, url authentication, dynamic watermarking, screen capture prevention for certain device/browsers, Geo restriction). It is a lengthy video (28 min), but we bet that you won’t have any questions unanswered on video protection after watching this.

Also, feel free to check out our video encryption software, all you need to do is signup and upload your video. We take care of the encryption part, all you need to do is just embed your video on the page and voila, it’s done.
