2. Video coding format - Wikipedia

   en.wikipedia.org/wiki/Video_coding_format

   Although video coding formats such as H.264 are sometimes referred to as codecs, there is a clear conceptual difference between a specification and its implementations. Video coding formats are described in specifications, and software, firmware , or hardware to encode/decode data in a given video coding format from/to uncompressed video are ...

   Between 1988 and 1991, several European organizations were working on DCT-based digital video coding standards for both SDTV and HDTV. The EU 256 project by the CMTT and ETSI, along with research by Italian broadcaster RAI, developed a DCT video codec that broadcast SDTV at 34 Mbit/s and near-studio-quality HDTV at about 70–140 Mbit/s.

4. Comparison of video codecs - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_video_codecs

   Each compression specification defines various mechanisms by which raw video (in essence, a sequence of full-resolution uncompressed digital images) can be reduced in size, from simple bit compression (like Lempel-Ziv-Welch) to psycho-visual and motion summarization, and how the output is stored as a bit stream. So long as the encoder component ...

   The H.261 standard was developed based on DCT compression, [15] becoming first practical video coding standard. [14] Since H.261, DCT compression has been adopted by all the major video coding standards that followed. [15] MPEG-1, developed by the Motion Picture Experts Group (MPEG), followed in 1991, and it was designed to compress VHS-quality ...

   Overhead is affected by the total number of packets and by the size of stream packet headers. In high bitrate encodings, the content payload is usually large enough to make the overhead data relatively insignificant, but in low bitrate encodings, the inefficiency of the overhead can significantly affect the resulting file size if the container ...

7. Discrete cosine transform - Wikipedia

   Illustration of the implicit even/odd extensions of DCT input data, for N=11 data points (red dots), for the four most common types of DCT (types I-IV). Note the subtle differences at the interfaces between the data and the extensions: in DCT-II and DCT-IV both the end points are replicated in the extensions but not in DCT-I or DCT-III (and a ...

8. Streaming television - Wikipedia

   en.wikipedia.org/wiki/Streaming_television

   Streaming television is the digital distribution of television content, such as television series and films, streamed over the Internet. [1] Standing in contrast to dedicated terrestrial television delivered by over-the-air aerial systems, cable television, and/or satellite television systems, [2] streaming television is provided as over-the-top media (OTT), [3] or as Internet Protocol ...

9. Advanced Video Coding - Wikipedia

   Therefore, the difference between hardware and software based implementation is more on power-efficiency, flexibility and cost. To improve the power efficiency and reduce hardware form-factor, special-purpose hardware may be employed, either for the complete encoding or decoding process, or for acceleration assistance within a CPU-controlled ...
