Hd Production Codecs
نویسنده
چکیده
The introduction of HDTV in Europe requires that broadcasters renew their production equipment. Whilst HDTV equipment in the past has targeted tape-based solutions, the user requirements for modern HDTV production workflows are file-based, non-linear and non-real-time – with shared access via networks and servers – and, last but not least, they have to be cost-effective. These requirements put challenges on the video compression format applied in mainstream HDTV production equipment – particularly on the trade-off between the data rate and video-quality headroom.

Subjective Evaluation of Hevc Intra Coding for Still Image Compression
High Efficiency Video Coding (HEVC) demonstrates a significant improvement in compression efficiency compared to H.264/MPEG-4 AVC, especially for video with resolution beyond HD, such as 4K UHDTV. One advantage of HEVC is the improved intra coding of video frames. Hence, it is natural to question how such intra coding compares to state of the art compression codecs for still images. This paper ...
متن کاملTowards Battery-Free HD Video Streaming
Video streaming has traditionally been considered an extremely power-hungry operation. Existing approaches optimize the camera and communication modules individually to minimize their power consumption. However, designing a video streaming device requires power-consuming hardware components and computationally intensive video codec algorithms that interface the camera and the communication modu...
متن کاملEosinophilia and cellular cytokine responsiveness in hemodialysis patients.
Eosinophilia in hemodialysis (HD) patients has been associated with allergy to dialyzers and exaggerated activation of complement during HD. Its etiology, however, remains unknown. Complement activation can lead to cytokine production, and interleukin-2 (IL-2) administration has been shown to cause eosinophilia. Because abnormalities in cellular cytokine production in renal patients were previo...
متن کاملSIC and Wavelet Software Video Codecs
In order to achieve low bit rate transmission of video data, compression techniques are needed. Segmented image coding (SIC) and wavelet are two relatively new but powerful techniques used for compression of still images and/or video. The low complexity of these compression techniques allows software implementation on general purpose processors. A SIC and a wavelet compression algorithm, propri...
متن کاملWideband voice challenges
To achieve a richer and more accurate audio experience over the telephone, standard-definition (SD) voice could soon be replaced with high-definition (HD) voice based on Voice over IP (VoIP) technology. However, more issues are involved in HD telephony than simply the implementation of wideband codecs in IP phones or media gateways. A lack of agreement on a standard wideband codec is a serious ...
