Hybrid platform for content delivery and transcoding

Abstract

The subject matter herein generally relates to transcoding content, typically audio/video files though not limited to such, from one version to another in preparation for online streaming or other delivery to end users. Such transcoding may involve converting from one format to another (e.g., changing codecs or container formats), or creating multiple versions of an original source file in different bitrates, frame-sizes, or otherwise, to support distribution to a wide array of devices and to utilize performance-enhancing technologies like adaptive bitrate streaming. A transcoding platform is described herein that, in certain embodiments, leverages distributed computing techniques to transcode content in parallel across a platform of machines that are preferably idle or low-utilization resources of a content delivery network. The transcoding system also utilizes, in certain embodiments, improved techniques for segmenting the original source file so as to enable different segments to be sent to different machines for parallel transcodes.

AI Technical Summary

Benefits of technology

The patent discusses a technology used to convert video and audio files into different forms for viewers who watch them on computers or mobile devices. This process involves dividing the file into smaller parts and giving each part to a separate machine to work with simultaneously. By doing this, the conversion happens faster and more efficiently.

Problems solved by technology

This patent discusses the challenges faced by content providers when trying to distribute their content online through various platforms like web browsers and mobile apps. To ensure optimal performance, they need to generate numerous variations of the same content, called "versions," which can differ in things like resolution, timing, and compression method. These versions consume significant resources and make management difficult. Additionally, CDNs (which help speed up content delivery) further complicate matters because they require even greater amounts of resource allocation. Therefore, the technical problem addressed by the patent is finding ways to efficiently and effectively prepare and transform streaming content into different versions while maintaining compatibility with delivery solutions.
