A number of extensions have been made to TCP over the years to increase its performance over fast high-RTT links ("long fat networks" or LFNs). TCP timestamps (RFC 1323) play a double role: they avoid ambiguities due to the 32-bit sequence number field wrapping around, and they allow more precise RTT estimation in the presence of multiple ...
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
For signals of indefinite size, such as streaming audio and video, the compression ratio is defined in terms of uncompressed and compressed data rates instead of data sizes: C o m p r e s s i o n R a t i o = U n c o m p r e s s e d D a t a R a t e C o m p r e s s e d D a t a R a t e {\displaystyle {\rm {Compression\;Ratio}}={\frac {\rm ...
VP8 is a traditional block-based transform coding format. It has much in common with H.264, e.g. some prediction modes. [8] At the time of first presentation of VP8, according to On2 the in-loop filter [9] and the Golden Frames [10] were among the novelties of this iteration.
cFosSpeed is a traffic shaping software often bundled with MSI motherboards for the Windows operating system. The program attaches itself as a device driver to the Windows network stack where it performs packet inspection and layer-7 protocol analysis. It has been noted as causing some issues with network connections, and can be difficult to ...
Windows Media Video Image (WMV Image) is a video slideshow format. The format works by applying timing, panning and transition effects to a series of images during playback. [ 20 ] The codec achieves a higher compression ratio and image quality than WMV 9 for still images as files encoded with WMV Image store static images rather than full ...
Most video coding standards, such as the H.26x and MPEG formats, typically use motion-compensated DCT video coding (block motion compensation). [69] [70] Most video codecs are used alongside audio compression techniques to store the separate but complementary data streams as one combined package using so-called container formats. [71]
It is somewhat analogous to the so-called fourcc code, used for a similar purpose for media embedded in AVI container format. [59] A brand might indicate the type of encoding used, how the data of each encoding is stored, constraints and extensions that are applied to the file, the compatibility, or the intended usage of the file.
