<\/span>Key Technologies to build OTT platform<\/span><\/h2>\n\n\n\n<\/span>Content Delivery Network (CDN)<\/span><\/h3>\n\n\n\nA CDN <\/strong>is crucial for delivering high-quality video content efficiently across the globe. It minimizes latency by distributing content through a network of servers, ensuring seamless streaming even during high traffic. However, serving videos from CDN costs a lot of money to the organization. Organizations can optimize CDN cost in the following ways:<\/p>\n\n\n\n\n- Only serve the most popular videos from CDN and other videos from high-capacity storage video servers.<\/li>\n\n\n\n
- For less popular content, we may not need to store many encoded video versions. Short videos can be encoded on-demand.<\/li>\n\n\n\n
- Some videos are popular only in certain regions. There is no need to distribute these videos to other regions.<\/li>\n\n\n\n
- Build your own CDN like Netflix and partner with Internet Service Providers (ISPs). Building your CDN is a giant project; however, this could make sense for large streaming companies. An ISP can be Comcast, AT&T, Verizon, or other internet providers. ISPs are located all around the world and are close to users. By partnering with ISPs, you can improve the viewing experience and reduce the bandwidth charges.<\/li>\n<\/ul>\n\n\n\n
<\/span>Video Encoding and Transcoding<\/span><\/h3>\n\n\n\nVideo Encoding and Transcoding<\/strong> are essential processes in the creation and distribution of video content for OTT platforms. <\/p>\n\n\n\n\n- Video Encoding:<\/strong> This is the process of compressing raw video files to reduce their size without significant loss of quality. Compression makes the files easier to store and transmit over the internet. Encoded videos are formatted to ensure smooth streaming while maintaining clarity.<\/li>\n\n\n\n
- Video Transcoding:<\/strong> This involves converting the already encoded video into various formats, resolutions, and bitrates. Transcoding ensures that the content is compatible with a wide range of devices and internet speeds. For example, the same video might be available in high-definition (1080p) for users with fast internet and in standard-definition (480p) for those with slower connections.<\/li>\n<\/ul>\n\n\n\n
Together, encoding and transcoding enable OTT platforms to deliver flexible and high-quality viewing experiences to users on diverse devices and networks. codecs<\/strong> are the technologies or algorithms used to compress and decompress digital video and audio data. The term “codec” is a combination of “compressor” and “decompressor.”. Popular codecs are H.264, H.265, VP9, AV1.<\/p>\n\n\n\n<\/span>Adaptive Bitrate Streaming (ABR)<\/span><\/h3>\n\n\n\nABR <\/strong>technology adjusts the video quality in real-time based on the user\u2019s internet speed and device capabilities, providing a buffer-free viewing experience. All the modern video streaming giants use Adaptive bitrate streaming(ABR) to provide the best possible streaming experience to their users, irrespective of the network bandwidth and device capabilities. ABR flow is as follows:<\/p>\n\n\n\n\n- When a video is uploaded, It is splitted into manageable sections each of which is encoded at many different quality levels.<\/li>\n\n\n\n
- The video player on the client side determines the bandwidth and CPU capacity in real time and accordingly requests the best quality portion that can be broadcast smoothly without much buffering. <\/li>\n\n\n\n
- This implies that to prevent interruptions to the video playing, video quality is automatically modified if the viewer\u2019s internet speed changes.<\/li>\n<\/ul>\n\n\n\n
<\/span>Pre-Signed URLs<\/span><\/h3>\n\n\n\nTo ensure only authorized users upload videos to the right location, pre-signed URLs<\/strong> are used.<\/p>\n\n\n\n\n\nThe upload flow required to be updated as follows:<\/p>\n\n\n\n
1. The client makes an HTTP request to API servers to fetch the pre-signed URL, which gives access permission to the object identified in the URL. The term pre-signed URL is used in the context of AWS. Other cloud service providers might use a different name. For instance, Microsoft Azure blob storage supports the same feature, but calls it \u201cShared Access Signature\u201d.<\/p>\n\n\n\n
2. API servers respond with a pre-signed URL.<\/p>\n\n\n\n
3. Once the client receives the response, it uploads the video on cloud storage using the pre-signed URL.<\/p>\n\n\n\n
<\/span>Digital Rights Management (DRM)<\/span><\/h2>\n\n\n\nIt refers to a set of technologies designed to protect digital content from unauthorized access, copying, and distribution. For OTT platforms, DRM <\/strong>ensures that video content is securely delivered to authorized users only, safeguarding the rights of content creators and distributors.<\/p>\n\n\n\n<\/span>1. AES encryption<\/span><\/h3>\n\n\n\nVideo can be encrypted using an authorization policy. The encrypted video will be decrypted upon playback. This ensures that only authorized users can watch an encrypted video.<\/p>\n\n\n\n
<\/span>2. Visual watermarking<\/span><\/h3>\n\n\n\nThis is an image overlay on top of your video that contains identifying information for your video. It can be your company logo or company name.<\/p>\n\n\n\n
<\/span>3. Cloud Infrastructure <\/span><\/h3>\n\n\n\nA scalable cloud infrastructure<\/strong> is essential for storing vast amounts of content and handling fluctuating user demand. Providers like AWS, Google Cloud, or Azure offer reliable solutions tailored for OTT platforms.<\/p>\n\n\n\n<\/span>4. Analytics Tools<\/span><\/h3>\n\n\n\nIntegrated analytics tools help track user behavior, content performance, and subscription metrics. Insights derived from analytics can drive personalized recommendations and marketing strategies.<\/p>\n\n\n\n
<\/span>5. Payment Gateway Integration<\/span><\/h3>\n\n\n\nSeamless and secure payment processing is a cornerstone of subscription-based models. Supporting multiple payment methods and currencies enhances user convenience.<\/p>\n\n\n\n
<\/span>6. Queue Services<\/span><\/h3>\n\n\n\nQueue services like RabbitMQ, Kafka, or SQS are pivotal in managing high-volume, asynchronous tasks. These services:<\/p>\n\n\n\n
