H.264

Also known as Advanced Video Coding (AVC). A standard for video compression used for the recording, compression, and distribution of high definition video.

H.265

Also known as High Efficiency Video Coding (HEVC) and MPEG-H Part 2. HEVC is a video compression standard designed as part of the MPEG-H project as a successor to the widely used Advanced Video Coding (AVC, H.264, or MPEG-4 Part 10)

HDCP

Abbreviation of High-bandwidth Digital Content Protection. A form of digital copy protection developed by Intel Corporation to prevent copying of digital audio and video content as it travels across connections.

HDS

Abbreviation of HTTP Dynamic Streaming. The process of efficiently delivering streaming video to users by dynamically switching among different streams of varying quality and size during playback.

HE-AAC

Abbreviation of High Efficiency Advanced Audio Coding. An audio coding format for lossy data compression of digital audio defined as an MPEG-4 Audio profile in ISO/IEC 14496-3.

HEVC

Abbreviation of High Efficiency Video Coding. Also known as H.265 and MPEG- H Part 2. HEVC is a draft video compression standard, currently under development as a successor to H.264/MPEG-4 AVC (Advanced Video Coding).

High Profile

Most efficient of the top three profiles. Packs more quality into a given bitrate. Hardest to process. Originally intended for high- definition applications such as Blu-Ray, however becoming popular for web-video applications due to the increase in processing power.

HLS

HTTP Live Streaming. An HTTP-based media streaming communications protocol implemented by Apple Inc. as part of its QuickTime, Safari, OS X, and iOS software.

Hostname

Label that is assigned to a device on a network and identifies that device in electronic communication, such as on the Web.

HTTP

Hypertext Transfer Protocol. Application protocol for distributed information systems. It is the foundation for communication on the World Wide Web.

HTTP Dynamic Streaming

Abbreviated as HDS. The process of efficiently delivering streaming video to users by dynamically switching among different streams of varying quality and size during playback.

HTTPS

HTTP Secure. Adaptation of HTTP for secure communication over a network and is widely used on the Internet.
