Live Video Transcoding

GPU Accelerated Low Latency Live Transcoding for OTT Streaming and Broadcast Distribution.

Delivering high-demand live events to any device anywhere in the world is hard. The Zixi Software Platform makes it easier with integrated low latency live transcoding, taking in mezzanine live video streams and transcoding to broadcast quality H.265/HEVC and H.264/AVC. For OTT streaming video platforms and Social Media/eSports Zixi Live Transcode supports packaging to HLS, DASH, and RTMP.  In addition, format and standards conversion are automated with live backhaul via Zixi protocol, RIST, RTP, SRT and UDP for reintegration into broadcast systems.

The Zixi Software Platform can conduct video transcoding at the source (or via satellite, fiber or any IP network) and deliver any required protocol over a public or private IP network. Our live transcoding software keeps our OTT service providers up to speed with the demands of content customization, new advertising opportunities and the need for flexible scaling.

How Does Video Transcoding Work?

Video transcoding refers to the process of decoding, processing, and encoding media streams. It starts with software analyzing the original stream to determine their audio and video codecs, bitrate, frame rate, and resolution. If the current specifications are not optimal, the video and audio streams are transcoded through several steps that include demultiplexing the video stream into individual components such as audio, video and subtitles etc allowing for optimization based on desired output format followed by video decoding which brings the video into an uncompressed format and finally re-encoding and multiplexing into a new codec or format which is required by the target platform.

Broadcast and Live Video Distribution

In Broadcast and Live Video Distribution, transcoding plays a crucial role in delivering high-quality, reliable video content to a global audience. This involves:

  • Live Transcoding: Real-time conversion of video streams to different formats and bitrates to support multiple devices and network conditions.
  • Distribution: The transcoded video streams are then distributed through Content Delivery Networks (CDNs) to reach the end-users efficiently.
  • Latency Management: Minimizing latency to ensure live broadcasts are delivered with minimal delay.

Zixi Live Transcoding

Zixi specializes in delivering live broadcast-quality video over IP. Zixi’s live transcoding services offer several advantages for broadcasters and live video distributors:
