What are the procedures that need to be taken in order to include video DRM into my website or app?

Before it can be integrated into media websites and applications, the digital rights management (DRM) technology must first be integrated. This technology prevents digital content from being utilised in an inappropriate manner by applying data encryption for DRM video protection. Before something like this can be put into action, it must first be completed, which is a multi-step process. Before the video files can be transferred to the user’s device, they need to first be transcoded using a process called transcoding in order to be changed into forms that are compatible with streaming. Only after this process is complete can the files be transferred. MPEG-DASH and HLS are the formats that are utilised for this purpose the vast majority of the time. Both MPEG-DASH and conventional encryption, abbreviated as CENC, are supported by digital rights management (DRM) technologies including Microsoft’s PlayReady and Google’s Widevine, respectively. This demonstrates that the encrypted packet can be decrypted via any of the DRM approaches; hence, both of these ways can be considered to be valid solutions. On the other hand, Apple’s FairPlay employs the SAMPLE-AES encryption standard in addition to the HLS packaging standard. Both of these standards were developed by Apple. As a consequence of this, the video asset will require additional encryption and packaging in order for it to be utilised across all three platforms. Using a multi-DRM service, which enables the simultaneous encoding of videos into MPEG-DASH with CENC encryption and HLS with SAMPLE-AES encryption in a single process, is the approach that is most commonly used to finish this work. This is because multi-DRM services permit simultaneous encoding of videos. This strategy is also the method that is used the most frequently. As a direct result of this change, the process now goes off with very few hiccups.

Website proprietors who want to stream content using DRM video protection are required to generate an encryption key, an asset ID, and a key ID for every asset that is to be transmitted to the client in an encrypted format using DRM technology. This is one of the requirements that must be met in order to stream content. This is done in order to ensure that the content may be sent to the customer in a safe and secure manner. The ability to broadcast the content is contingent on satisfying this requirement. The data is encrypted using an AES key that contains 128 bits, and this is done for both FairPlay and CENC. However, FairPlay additionally requires the use of an Initialization Vector, thus this cannot be done for CENC (IV). CENC does not require an extra IV. The client-side content decryption module, also known as CDM, is able to use the keys to decode the material by utilising the client’s own copy of the encryption algorithm once the keys have been ingested into the licenced server and the CDM has been given permission to do so. It is of the utmost importance that proprietors of websites constantly preserve a backup copy of the keys that are utilised inside their content platform. This will make it feasible for the keys to be retrieved quickly in the event that there is a switch to a different licence server in the near future. The switch could happen at any time. Streaming platforms, for the most part, ensure that both the licence server and the subscription server are operational in order to make DRM integration as simple and straightforward as is humanly possible. The subscription server is the one that determines whether or not the viewer is permitted to view the content; however, the licencing server is the one that is responsible for authenticating the player’s identification and granting the licence. Both servers work together to ensure that only authorised viewers can view the content.

The content, after being compressed by multiple digital rights management servers, is then uploaded to a content delivery network (CDN), such as Amazon Web Services (AWS). From there, it is delivered to the end user by way of a convoluted process that involves the server of the multi-DRM vendor, the server of the DRM technology provider, the content delivery network (CDN), and the client device or browser. This is how it gets to the end user. The CDM is the component that is in charge of handling the decryption that is involved in the communication that takes place between the licencing server and the browser. The CDM is present in all devices that are compatible with EME, which stands for Encrypted Media Extensions, and is the component that can be found in all EME-compatible devices. In addition to this, it is the component that can be found on every single device that is compatible with EME (Encrypted Media Extensions). Encrypting the chats makes use of a technique known as challenge-response, which helps ensure that the encryption keys do not fall into the wrong hands and get rendered useless as a result.

After the Content Delivery Manager (CDM) has validated the licencing key and encrypted the video asset blocks, the video can then be played back on HTML5 players.
