·Multibitrate support — ability to shift quality
depending on bandwidth and computer power. HTTP progressive delivery consumes
more bandwidth because it's not intelligent enough to throttle the delivery
(for example, a 30-minute video will be fully downloaded whether the user
watches it or not).
·Seeking within the video — ability to move around within a
long-format video without downloading it first
·Bandwidth control — ability to manage download
bandwidth to not disrupt other applications
·Support for live streaming with DVR and real-time protection
using Adobe Access
To deliver a streaming experience over HTTP, media assets need to go through a
fragmentation process that can also apply content protection (called
fragmenting), and a special module installed in the HTTP server is required.
The player can be built using OSMF, just like progressive download.
·Reach — Flash Player is a cross-platform browser plug-in
that delivers breakthrough online experiences to over 99% of Internet users.
·Open standards — HTTP Dynamic Streaming is built
on standards and deployed using standard HTTP servers (Apache), standard media
format (MP4 fragment) using standard codecs (H.264/AAC), open APIs (Flash
Player), and an open source framework for building media players (OSMF). The
file format will also be published, enabling advanced use cases of the format.
·Live publishing options — HTTP Dynamic Streaming supports
a separate process for packaging and protecting live content — allowing any
RTMP stream to be easily converted to a file format that can be delivered
·Interactivity — On the Flash Platform, media
delivery can be synchronized with real-time interactivity and robust logging,
all within the same application. Flash Player is also used by over 70% of web
games, making it easy to add even more social and interactive experiences to
·Content protection — With Adobe Access support in
Flash Player 10.1, Adobe can offer a robust, protected solution for content
delivery and monetization.
Streaming (HDS) enables on-demand and live adaptive bitrate video delivery of
standards-based MP4 media over regular HTTP connections. HDS lets you leverage
existing cache infrastructures and provides tools for integration of content
preparation into existing encoding workflows.
HTTP Dynamic streaming enables high-quality (H.264 or VP6), network-efficient
HTTP streaming for media delivery that is tightly integrated with Adobe® Access
software for robust content protection in the Adobe Flash® Player 10.1 or later
and Adobe AIR® 2 or later runtimes. This open format solution allows online
publishers to leverage existing network and cache infrastructures to
efficiently deliver media content to the Adobe Flash Platform. Adobe Media
Server software will continue to be a great option for streaming, multiway
communication, as well as advanced interactive experiences such as quick start
times and quick seeking. Like Adobe Media Server, HTTP Dynamic streaming
supports quality of service (QoS) monitoring, adaptive bitrate streaming, and
DVR functionality. The HTTP Dynamic Streaming workflow includes content
preparation tools, fragmented MP4 files that are HTTP cache‐friendly, a
playback framework (Open Source Media Framework, or OSMF), and options for
protected streaming powered by Adobe Access, continuing to make the Flash Platform
the choice for reliable delivery of protected, high-quality playback
HTTP Dynamic Streaming utilizes the same HTTP server technology used to
delivery progressive downloaded video. The new technology is different because
HTTP Dynamic Streaming is designed for online publishers that deliver to large
audiences requiring high capacity and scalability to meet traffic peaks or
those customers with high-quality video leveraging the benefits and reach of
the Adobe Flash Platform.
Adobe provides a full-featured HTTP delivery solution with the greatest reach
of any media delivery platform.
