Zencoder Launches Highly-Optimized HTTP直播(HLS) Video Preparation for iPhone and iPads

Results in Most Efficient Segmenting for HLS; Lower Video Storage and Delivery Costs for Content Providers

旧金山(2011年12月7日)

Zencoder, a leader in high-performance cloud-based video and audio encoding, today announced the immediate availability of highly-optimized HTTP 在线直播 encoding for Apple iOS devices, 比如iPad和iPhone. This allows smaller file sizes with no decrease in quality, and results in real-world storage and delivery savings of up to 10%.

HTTP直播(HLS), Apple's video streaming standard for iOS devices, 使用MPEG-TS文件格式. This format was designed for broadcast transmission and storage and adds significant overhead to video files. Because HLS playback only uses a subset of the MPEG-TS format, Zencoder has released HLS segmenting tools that result in file overhead dramatically lower than competitors, and that match the optimization of Apple's own proprietary tools. This means that Zencoder offers the only optimized HTTP 在线直播 implementation available in the cloud. In tests run by a third party, Zencoder segmenting produced files with up to 70% less overhead than Sorenson Media, up to 84% less overhead than Encoding.com, and up to 50% less overhead than Harmonic's ProMedia Carbon.

"Performance is our number one priority, and encoding efficiency is a big part of this. Our optimized MPEG-2 TS output results in smaller files, and this translates into real cost savings for our customers,乔恩·达尔说, Zencoder联合创始人兼首席执行官.

Jon Brendsel, PBS的产品副总裁, 现有的Zencoder客户, underscored the significance of this improvement: "In November, PBS served over 88 million streams and hundreds of terabytes of video data to our three iOS video apps. 在这些层面上, file size improvements translate to improved viewing experiences as well as cost savings for PBS."

This is the latest in a series of series of announcements from Zencoder that cement its position as the market leader in cloud-based video encoding. 10月, Cloud Harmony released a series of benchmarks demonstrating that Zencoder has the fastest encoding of any cloud provider. Zencoder also recently released its latest volume numbers, and at over 2 million encoded videos per month, is the largest transcoding service in the cloud.

The Zencoder platform delivers a 99.编码成功率9%, supports the greatest number of input video formats in the industry, and offers the fastest video transcoding available in the cloud. 使用一个简单的REST API, Zencoder's customers can easily access highly scalable, professional-quality video and audio encoding technology without expensive upfront hardware investments or ongoing maintenance fees. Zencoder works with hundreds of customers worldwide, 包括PBS电视台, TwitVid, Posterous, 大学幽默和抱怨.
