Requirements for Broadcast-Quality Live Streaming

Moving TV broadcasting to the cloud, streaming large-scale sporting events, and live streaming for paid video services involve requirements that simple streaming services such as IVS cannot meet. These include broadcast-quality transcoding (HEVC/H.265 support, HDR, 4K), content protection with DRM, server-side ad insertion (SSAI), simultaneous generation of multiple delivery formats (HLS, DASH, CMAF), multi-CDN delivery, and high availability through redundant configurations. The AWS Elemental media services provide broadcast-quality live streaming pipelines that meet these requirements. You build an end-to-end delivery platform by combining MediaLive (transcoding), MediaPackage (packaging and origin), MediaConnect (video transport), and MediaTailor (ad insertion), together with Amazon S3 as needed.

Real-Time Transcoding with MediaLive

MediaLive is a real-time transcoding service for live video. It receives video from input sources such as RTMP, RTP, HLS, and MediaConnect and converts it simultaneously into multiple resolutions and bitrates. You can define an ABR (Adaptive Bitrate) ladder and, for example, generate four output tiers simultaneously: 1080p/5Mbps, 720p/3Mbps, 480p/1.5Mbps, and 360p/800kbps. Supported codecs are H.264 (AVC) and H.265 (HEVC), and because HEVC can deliver the same picture quality at about half the bitrate of H.264, it is effective for reducing bandwidth costs. There are two channel classes, SINGLE_PIPELINE (single pipeline) and STANDARD (redundant pipelines); STANDARD processes video in two independent pipelines, so delivery continues even if one of them fails. For broadcast-quality delivery, the STANDARD class is essential.

MediaPackage with DRM and Ad Insertion

MediaPackage is a service that receives MediaLive output and packages it into formats suited to viewers' devices. With Just-in-Time packaging, it dynamically generates HLS (Apple devices), DASH (Android, Web), CMAF (low latency), and MSS (legacy Windows) formats from a single input. Because there is no need to generate and store every format in advance, you can reduce storage costs. For DRM integration, it supports the three major DRM systems, Widevine (Google), FairPlay (Apple), and PlayReady (Microsoft), and works with DRM key servers through the SPEKE (Secure Packager and Encoder Key Exchange) protocol. Integration with MediaTailor enables server-side ad insertion (SSAI). Because SSAI stitches ads into the content stream on the server side and delivers them as the same segments as the main content, it is harder for client-side ad blockers that work by blocking ad URLs and domains to bypass. However, tracking requests used to measure ad views and operations on the player side can still be blocked, so it is not a mechanism that can never be bypassed.

MediaConnect and Delivery Architecture

MediaConnect is a highly reliable live video transport service used for video transmission between broadcasters and between sites. It supports SRT (Secure Reliable Transport) and the Zixi protocol, enabling broadcast-quality video transport even over the internet. It ensures high availability with redundant flows and provides video quality monitoring metrics in real time. A typical delivery architecture follows the flow video source → MediaConnect (transport) → MediaLive (transcoding) → MediaPackage (packaging) → CloudFront (CDN delivery) → viewer devices. Note that each Elemental service cannot necessarily be used in the same way in every Region. In AWS's service availability update (June 2026), support for MediaLive and MediaPackage in some Regions is stated to end on June 30, 2026, so check availability in the Region you plan to use before deciding on a configuration (as of August 2026). When you operate a 24/7, 365-day live channel, channel running time translates directly into cost. The breakdown of pricing is covered together in the next section.

Elemental Pricing

(On-Demand pricing in US East (N. Virginia) as of August 2026) MediaLive bills inputs and outputs separately, each with its own hourly rate. Input rates are divided by resolution and codec; receiving 1080p / HEVC / 20 Mbps video on a standard channel (redundant pipelines) costs $0.588 per hour, or $0.3528 with a single pipeline. Input via Elemental Link follows a separate scheme: $0.50 per hour for HD (single pipeline) and $4.583 for UHD (standard channel). Output is divided into three tiers, SD (below 720p), HD (720p to 1080p), and UHD, and there is no separate "Full HD" tier. For AVC / 30 fps / standard channel, HD output costs $0.702 per hour and SD output costs $0.354. With a single pipeline, the rates drop to $0.4212 for HD and $0.2124 for SD, but because you lose redundancy, this is a hard option to choose for broadcast use. HEVC raises the rate in exchange for bitrate efficiency: 1080p HEVC output on a standard channel costs $2.808 per hour, and 2160p UHD costs $11.232. Also note that if you do not set the frame rate explicitly, the rate for over 30 fps applies. Because the ABR ladder is billed per output tier, the number of ladder tiers adds directly to the hourly rate. MediaPackage live packaging has two charges, $0.030 per GB for ingest into the channel and $0.050 per GB for origin delivery to the CDN, and delivery to viewers itself is charged at CloudFront rates. MediaStore, which was used as low-latency origin storage, was discontinued on November 13, 2025, and today you use the origin features of MediaPackage or Amazon S3 instead. There are two key points for cost management. One is to start and stop channels according to the delivery schedule (channels are billed for running time even when idle and not streaming video). The other is to apply 12-month reserved pricing to always-on channels, for which a reduction of up to 75% compared with On-Demand is advertised. Rates vary by Region, so check actual estimates against the official pricing page for the Region you use.

Redundancy and Quality Monitoring for Live Streaming

Because live streaming cannot be redone, a design in which delivery does not stop is more important than anything else. If you duplicate the transcoding processing path, the other path can continue delivery even if one fails. If you also prepare multiple input video sources and set up a mechanism that switches automatically when one drops out, you can withstand failures on the input side as well. During delivery, you put in place a system that monitors video and audio quality, latency, and the occurrence of errors in real time so that you can respond immediately to any anomaly. To deliver stable, uninterrupted streams to viewers, it is essential to design a robust architecture that makes each stage redundant and constantly monitors its state.

Summary - Guidelines for Using Elemental Media Services

The AWS Elemental media services are services for building broadcast-quality live streaming platforms in the cloud. You achieve an end-to-end delivery pipeline by combining MediaLive real-time transcoding, MediaPackage Just-in-Time packaging and DRM, MediaConnect highly reliable video transport, and MediaTailor ad insertion. They are suited to large-scale delivery that requires DRM, ad insertion, and broadcast-quality transcoding. If you need only interactive low-latency streaming, consider IVS.
