video codec

(1) (video enCOder/DECoder) Software that compresses and decompresses a digital video signal. MPEG, Windows Media Video (WMV) and H.264 are examples of popular codecs that compress and decompress digital video. The video codec may also be a hardware circuit. See codec examples, codec, MPEG, Windows Media formats, QuickTime, H.264 and VC-1.

(2) (video enCOder/DECoder) A hardware circuit that converts analog video (NTSC, PAL, SECAM) into digital code and vice versa. The circuit may provide only the A/D and D/A conversion, or it may include a compression algorithm to further reduce the signal such as defined in #1 above. See codec.

Once such device is video decoder, it is a data-intensive video processing device, which is an integrated circuit chip that converts digital video signals to analog video format.
Argon Streams is a set of conformance test bit-streams providing full coverage and verification of HEVC/H.265 video decoders. The bit-streams are derived directly from the specification using Argon Design's advanced compiler technology.
has released full conformance test bit- streams for the verification of all four profiles used by VP9 video decoders.
North Korea used third parties to buy the computer parts, including a US video decoder and UK-sourced temperature and pressure sensors, from re-sellers.
A video decoder could be parallelized to speed up the decoding with 2D-Wave, except for the entropy decoding stage.
Part of Imagination's Series5 family, the PowerVR D5500 is a multi-standard, multi-stream video decoder with a multi- core architecture that allows performance to be easily scaled for high resolution or high frame rate applications up to full HEVC level 5.0 using mainstream silicon processes at ultra-low power consumption.
The HDV62A delivers uncompressed high-definition video data from DVI or HDMI and provides an analog video decoder that supports RGB, NTSC/PAL, S-video, and YPbPr with an integrated audio decoder for HDMI and S/PDIF capture.
Included in the AMD FirePro W600 Professional Graphics card is: support for up to six high-resolution displays or projectors from a single-slot card and six mini DisplayPort connectors; 2GB of GDDR5 graphics memory for advanced multimedia performance; support for two HD video streams via AMD's Unified Video Decoder; projection overlap capability to create one seamless image, with planned support for projection edge blending and image warping in Q4 2012; AMD PowerTune technology that dynamically optimises power consumption during operation; and AMD ZeroCore Power technology to provide reduced power consumption at idle.
All ZN200/100 family of ICs use the powerful TransALL Transcode engine to allow for greater storage efficiency, support for devices with limited video decoder capabilities, assistance in Video QoS and enabling high-speed processing.
In general, mobile digital video transmission systems consist of a video encoder, a digital transmission method (e.g., Internet Protocol--IP), and a video decoder. The H.264/AVC encoder produces a sequence of compressed video frames that are encapsulated in to IP packets.
The product offers the following features: 1 or 2 x86 'Bobcat' CPU cores with 1MB L2 cache, 64-bit Floating Point Unit; up to 1.6GHz; 9W and 18W TDP; array of SIMD Engines; 3D and graphics processing; 3rd generation unified video decoder; power management features, including C6 and power gating; DDR3 800-1066 memory with support for 64 bit channel and 2 DIMMs; Ball Grid Array (BGA) package; 890mm physical footprint, including the AMD Fusion I/O Controller Hub.
The SVS-8 standalone model or SVS-8 SAM is designed for applications where a truly universal streaming network video decoder is required to drive digital video recorders, video monitors and other devices that accept a composite video signal.
