H.248協議，也叫MeGaCo協議，是媒體網關控制器（MGC）與媒體網關（MG）之間的一種媒體網關控制協議，這個協議是一項ITU-T與IETF合作結果的新標準。目前ITU-T、IETF、軟交換論壇等標準化組織正在加緊對H.248協議進行完善，各大電信設備制造商也在H.248協議的研發和應用上加大了投入。與MGCP協議相比，H.248協議可以支持更多類型的接入技術并支持終端的移動性，除此之外，H.248協議最顯著之處在于能夠支持更大規模的網絡應用，而且更便于對協議進行擴充，因而靈活性更強，已逐漸取代MGCP發展成為媒體網關控制協議的標準

H.264/AVC, the result of the collaboration between the ISO/IEC Moving Picture Experts Group and the ITU-T Video Coding Experts Group, is the latest standard for video coding. The goals of this standardization effort were enhanced compression efficiency, network friendly video representation for interactive (video telephony) and non-interactive applications (broadcast, streaming, storage, video on demand). H.264/AVC provides gains in compression efficiency of up to 50％ over a wide range of bit rates and video resolutions compared to previous standards. Compared to previous standards, the decoder complexity is about four times that of MPEG-2 and two times that of MPEG-4 Visual Simple Profile. This paper provides an overview of the new tools, features and complexity of H.264/AVC.

This document contains a detailed description of the usage and configuration of the JSVM [Joint Scalable Video Model] software for the Scalable Video Coding [SVC] project of the Joint Video Team [JVT] of the ISO/IEC Moving Pictures Experts Group [MPEG] and the ITU-T Video Coding Experts Group [VCEG]. It provides information how to build the software on Windows32 and Linux platforms. It contains a description of the usage and configuration for the binaries built from the software package, including examples for spatial, SNR and combined scalability scenarios. Guidelines for the integration and validation of new tools in the software are provided.

A certification path is an ordered list of certificates starting with a certificate issued by the relying party s trust root, and ending with the target certificate that needs to be validated. Certification path validation procedures are based on the algorithm supplied in ITU-T Recommendation X.509 and further defined in Internet Engineering Task Force (IETF) Request for Comments (RFC) 3280. Certification path processing verifies the binding between the subject distinguished name and/or subject alternative name and the subject public key defined in the target certificate. The binding is limited by constraints, which are specified in the certificates that comprise the path, and inputs that are specified by the relying party. To ensure secure interoperation of PKI-enabled applications, the path validation must be done in accordance with the X.509 and RFC 3280 specifications. This document provides the test assertions and the test cases for testing path validation software against these specifications.
