Introduction For many types of networks, reducing the deployment and operational costs by improving the usage of the bandwidth resources is of vital importance. Header compression over a link is possible because some of the information carried within the header of a packet becomes...
This document defines a framework for creating WebSocket extensions that add compression functionality to the WebSocket Protocol. An extension based on this framework compresses the payload data portion of WebSocket data messages on a per-message basis using parameters negotiated during the...
Purpose. A Johnstone test apparatus or equivalent (see SAE J1864) is used to conduct this test. A sealed steel cylinder (of initial volume of 150.76 cc) is filled completely, with material to be tested, loaded into the check load frame and subjected to a progressive increase in loading upon the...
In order to utilize digital images effectively, specific techniques are needed to reduce the number of bits required for their representation. This Tutorial Text provides the groundwork for understanding these image compression tecniques and presents a number of different schemes that have...
1.1 This specification covers the format and content of digitally recorded voice data files and their identifying data. The object is to enable transfer between independent digital dictation systems and workstations, regardless of manufacturer and protocols for ensuring reliability. This...
This Procedure is used to determine the physical behavior of a sealer material under pressure conditions. The materials compressibility/rebo
Covers hosiery exerting compression on upright legs, including pantihose, thigh-length and knee-length garments. Does not cover non-ambulatory garments, shaped bandages or individually-made garments. Specifies requirements for compression, compression profile,...
This document defines an additional mode of the link-layer assisted RObust Header Compression (ROHC) profile, also known as the zero-byte profile, beyond the two defined in RFC 3242. Zero-byte header compression exists in order to prevent the single-octet ROHC header from pushing a...
14-minute video which examines in layman's language the theory and principles involved in the compression of air. It shows how both positive displacement and dynamic type compressors operate and introduces the audience to key terms such as PSIG, SCFM, relative humidity and dew point.
This standard defines the VC-2 video compression system through the stream syntax, entropy coding, coefficient unpacking process and picture decoding process. The decoder operations are defined by means of a mixture of pseudo-code and mathematical operations. VC-2 is an intra frame video...
This Standard covers compression molded corrugated thermoplastic septic tank, sewage holding tank, and effluent chamber applications specified under CSA B66 and specifies requirements for sizing, design, materials, physical characteristics, performance testing, markings and literature. Note:...
This document describes how to implement certain mechanisms in Signaling Compression (SigComp), RFC 3320, which can significantly improve the compression efficiency compared to using simple permessage compression. SigComp uses a Universal Decompressor Virtual Machine (UDVM) for...
This document defines Signaling Compression (SigComp), a solution for compressing messages generated by application protocols such as the Session Initiation Protocol (SIP) (RFC 3261) and the Real Time Streaming Protocol (RTSP) (RFC 2326). The architecture and prerequisites of SigComp are...
Scope. This specification covers the requirements for a nylon duck duffel bag with four (4) compression straps and a center zipper closure to be used by military personnel of the Department of Defense.
Overview These technical requirements form a standard for the Link-Layer Assisted (LLA) Service Options. Service Option 60 (SO60) defines a variable rate Voice-over-IP (VoIP) service option for transport of header-removed IP/UDP/RTP packets carrying speech frames. Service Option 61 (SO61)...
This document describes an option for negotiating the use of header compression on IP datagrams transmitted over the Point-to-Point Protocol (RFC 1661). It defines extensions to the PPP Control Protocols for IPv4 and IPv6 (RFC 1332, RFC 2472). Header compression may be applied to IPv4...
This part of IEC 60268 defines the STI model, test signals, measurement and prediction methods. The objective of this document is to provide a comprehensive manual for all types of users of the STI model in the fields of audio, communications and acoustics. This document does not provide STI...
