| Concept | Category | Description | Related Concepts |
| AACS | Content Protection | Advanced Access Content System – standard for content distribution and digital rights management for recordable and pre-recorded media , intended to protect high definition video content on BluRay and HD-DVD discs | DRM |
| ABR Streaming | Media Streaming | Method of video streaming over HTTP where the source content is encoded at multiple bit rates. Streaming client is made aware of the available streams at differing bit rates, and segments of the streams by a manifest file and it requests for appropriate bit rate stream (varying quality) by detecting its bandwidth and CPU capacity in real time | Apple HLS, Microsoft Smooth Streaming, Adobe HDS, MPEG-DASH |
| Ad insertion | Ad Management | Process of inserting (splicing in) an advertising content into the media stream Broadcast (Linear) or online (Non Linear) programming . Also called Ad splicing | SCTE 30, SCTE 35, Cue Tones, DPI |
| Ad Scheduling | Ad Management | Process of selecting campaigns, Advertisements or content and establishing a time when the advertisement is going to run. It helps fixing up the time slots according to the advertiser so that the message to be delivered will reach target audience in a proper way with proper timings | Continuity, Flighting, Pulsing |
| Ad servicing | Ad Management | Process by which ad server (which stores advertisements used in online marketing) delivers advertisements to publisher websites. Ad server manages ad trafficking, targeting ads, optimizing bid prices, ad placement and impression reporting | Contextual advertising, CPC |
| ADSL | Data Transmission | ADSL (Asymmetric digital subscriber line) is data communications technology that enables faster data transmission over copper telephone lines, by utilizing frequencies that are not used by a voice telephone call. Data carried by the ADSL are routed over the telephone company’s data network and eventually reach a conventional Internet Protocol network. ADSL2+M supports downstream rate of 24 Mbps and upstream of 3.3 Mbps. | DSL |
| Advanced Audio Codec (AAC) |
Encoding Standard | Lossy compression and encoding scheme for digital audio which achives low data rate by discarding perceptually irrelevant data and redundancies in the coded audio signal . It is termed as successor of MP3 (MPEG 1, Layer 3) with better sound quality at similar bit rates. It is the default or standard audio format for YouTube, iPhone, iPod, iPad, Nintendo, iTunes, DivX Plus Web Player and PlayStation 3 and supports sample frequencies from 8 to 96 kHz. | MPEG 2, MPEG 4,Blu-ray, ATSC, ISDB-T, DVB-T, DVB-C, DVB-S, ISO 14496, HEVC |
| Advanced Video Coding (AVC) |
Encoding Standard | Standard for video compression popularly known as H.264/MPEG-4 Part 10. Video format has covers all forms of digital compressed video from low bit-rate Internet streaming applications to HDTV broadcast and Digital Cinema applications with nearly lossless coding (Achieves similar quality as MPEG-2 with less than half the bitrate). Standard is approved for Blu-ray, D2ATSC, ISDB-T, DVB-T, DVB-C, DVB-S and other . It supports VBSMC, uses multiple motion vectors per macroblock and allows upto 16 reference frames. It supports 21 sets of profiles (BP, MP, Main etc.) targeting specific classes of applications | MPEG 2, MPEG 4,Blu-ray, ATSC, ISDB-T, DVB-T, DVB-C, DVB-S, ISO 14496, HEVC |
| AES | Encryption | Advanced Encryption Standard is a specification for the encryption of electronic data using symmetric-key algorithm ( same key is used for both encrypting and decrypting the data). It is based on symmetric-key block cipher supporting a block size of 128 bits and key sizes of 128, 192, and 256 bits | DRM, DES, Triple-DES |
| Apple HLS | Media Streaming | Apple HTTP Live Streaming (HLS) is an adaptive streaming protocol which enables the player to dynamically adjust playback quality to match the available speed of network. It supports multiple alternate streams at different bit rates, and offers client software to switch streams intelligently as network bandwidth changes. All devices running iOS 3.0 and later include built-in client software for HTTP Live Streaming | Adobe HDS, Microsoft Smooth Streaming, MPEG DASH, Adaptive streaming |
| ASI | Streaming Interface | Asynchronous Serial Interface (ASI) is a streaming data format for carrying MPEG TS (Transport Stream). The | DVB-ASI |
| Aspect Ratio | Media | Aspect Ratio is an projection attribute that describes the proportional relationship between the width of an image and its height. Several Popular ratios are 1.33:1 (4:3) – Traditional television & computer monitor standard 1.5:1 (3:2) – Classic 35 mm still film 1.77:1 (16:9) – HD video standard 2.40:1 – Widescreen cinema standard |

| AAF | Standard | Advanced Authoring Format is a multimedia file format to exchange digital media and metadata across platforms. . It is more extendible and refined compared to OMF and uses Microsoft’s Structured Storage | OMF, MXF |
| ASI | Streaming Interface | Asynchronous Serial Interface (ASI) is a streaming data format for carrying MPEG TS (Transport Stream) | DVB-ASI |
| ATSC | Television Standard | (Advanced Television Systems Committee )ATSC is set of standards developed for digital television transmission over terrestrial, cable, and satellite networks. ATSC 1.0 relies on 8-VSB modulation scheme capable of delivering 19.39 Mbps in a 6 MHz TV channel, carrying SD/HD streams using MPEG-2 technology. Planning for ATSC 3.0 has started with launch expected in 2016 with focus on 4KTV, immersive audio, interactivity, multiscreen viewing, mobile access and hybrid services with improvements planned for flexible and efficient use of spectrum. | EIA-708, NTSC, |
| ARIB | Standard Body | Institution to conduct investigation, research & development and consultation of utilization of radio waves from the view of developing radio industries, and to promote realization and popularization of new radio systems in the field of telecommunications and broadcasting | |
| Analog Video | Video | Video signal transferred by an analog signal containing luminance, brightness (Y) and chrominance (C) | Composite, Component, S-Video, NTSC, PAL, SECAM |
| Ad Pods | Digital Video Ads | Ad Pods is the delivery of a set of sequential Linear ads (multi-ad group) which can represent multiple ads which play sequentially. Ad Pods can play before (pre-roll) , during a break in (mid-roll) , or after (post-roll) the content video plays.
