RTVideo

	RTVideo RTVideo is Microsoft's default video codec for Office Communications Server 2007 and the Microsoft Office Communicator 2007 client. It is a Microsoft proprietary implementation of the VC-1 codec for real-time transmission purposes. Microsoft extensions to VC-1 are based on cached frame and SP-frame. Also it includes system-level enhancements for recovery of packet loss on IP networks - forward error correction and error concealment. Licensing RTVideo is a proprietary codec.

	RTAudio RTAudio is a Microsoft produced adaptive wide-band speech codec. It is used by Microsoft Office Communications Server (OCS) and the related OCS clients (Microsoft Office Communicator, and Microsoft Live Meeting Console). RTAudio was designed for real-time two-way Voice over IP (VoIP) applications. Some of the target applications include games, audio conferencing, and wireless applications over IP. RTAudio is the preferred Microsoft Real-Time audio codec, and is the default voice codec for Microsoft’s Unified Communications platforms. The RTAudio encoder is capable of encoding single-channel (mono), 16 bit per sample audio signals. The encoder can be configured to operate either in the Narrow Band mode (8 kHz sampling rate) or the Wide Band mode (16 kHz sampling rate). The RTAudio decoder has a built-in jitter control module as well as an error concealment module. Licensing RTAudio is a proprietary codec. Like RTVideo RTVideo is Microsoft's default video codec ...

	Office Communications Server Skype for Business Server (formerly Microsoft Office Communications Server and Microsoft Lync Server) is real-time communications server software that provides the infrastructure for enterprise instant messaging, presence, VoIP, ad hoc and structured conferences (audio, video and web conferencing) and PSTN connectivity through a third-party gateway or SIP trunk. These features are available within an organization, between organizations and with external users on the public internet or standard phones (on the PSTN as well as SIP trunking). Features One basic use of Skype for Business Server is instant messaging (IM) and presence within a single organization. This includes support for rich presence information, file transfer and voice and video communication. Skype for Business Server uses Interactive Connectivity Establishment for NAT traversal and TLS encryption to enable secure voice and video both inside and outside the corporate network. Skype for Business Server also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Microsoft Office Communicator Skype for Business (formerly Microsoft Lync and Office Communicator) is an enterprise software application for instant messaging and videotelephony developed by Microsoft as part of the Microsoft Office suite. It is designed for use with the on-premises Skype for Business Server software, and a software as a service version offered as part of Office 365. It supports text, audio, and video chat, and integrates with Microsoft Office components such as Exchange and SharePoint. In 2015, the software was rebranded from Lync to Skype for Business, co-branding it with the Microsoft-owned consumer messaging platform Skype (which had begun to integrate with Lync in 2013). In September 2017, Microsoft announced that it would phase out Skype for Business Online in favor of Microsoft Teams, a new cloud-based collaboration platform. Support for Skype for Businesses Online ended in July 2021, although a new version of Skype for Business Server will be available with a subscription license. H ...

	VC-1 SMPTE 421, informally known as VC-1, is a video coding format. Most of it was initially developed as Microsoft's proprietary video format Windows Media Video 9 in 2003. With some enhancements including the development of a new Advanced Profile, it was officially approved as a SMPTE standard on April 3, 2006. It was primarily marketed as a lower-complexity competitor to the H.264/MPEG-4 AVC standard. After its development, several companies other than Microsoft asserted that they held patents that applied to the technology, including Panasonic, LG Electronics and Samsung Electronics. VC-1 is supported in the now-deprecated Microsoft Silverlight, the briefly-offered HD DVD disc format, and the Blu-ray Disc format. Format VC-1 is an evolution of the conventional block-based motion-compensated hybrid video coding design also found in H.261, MPEG-1 Part 2, H.262/MPEG-2 Part 2, H.263, and MPEG-4 Part 2. It was widely characterized as an alternative to the ITU-T and MPEG video cod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Packet Loss Packet loss occurs when one or more packets of data travelling across a computer network fail to reach their destination. Packet loss is either caused by errors in data transmission, typically across wireless networks, or network congestion.Kurose, J.F. & Ross, K.W. (2010). ''Computer Networking: A Top-Down Approach''. New York: Addison-Wesley. Packet loss is measured as a percentage of packets lost with respect to packets sent. The Transmission Control Protocol (TCP) detects packet loss and performs retransmissions to ensure reliable messaging. Packet loss in a TCP connection is also used to avoid congestion and thus produces an intentionally reduced throughput for the connection. In real-time applications like streaming media or online games, packet loss can affect a user's quality of experience (QoE). Causes The Internet Protocol (IP) is designed according to the end-to-end principle as a best-effort delivery service, with the intention of keeping the logic routers mus ...

picture info	Forward Error Correction In computing, telecommunication, information theory, and coding theory, an error correction code, sometimes error correcting code, (ECC) is used for controlling errors in data over unreliable or noisy communication channels. The central idea is the sender encodes the message with redundant information in the form of an ECC. The redundancy allows the receiver to detect a limited number of errors that may occur anywhere in the message, and often to correct these errors without retransmission. The American mathematician Richard Hamming pioneered this field in the 1940s and invented the first error-correcting code in 1950: the Hamming (7,4) code. ECC contrasts with error detection in that errors that are encountered can be corrected, not simply detected. The advantage is that a system using ECC does not require a reverse channel to request retransmission of data when an error occurs. The downside is that there is a fixed overhead that is added to the message, thereby requiring a h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Video Codecs The following is a list of compression formats and related codecs. Audio compression formats Non-compression * Linear pulse-code modulation (LPCM, generally only described as PCM) is the format for uncompressed audio in media files and it is also the standard for CD-DA; note that in computers, LPCM is usually stored in container formats such as WAV, AIFF, or AU, or as raw audio format, although not technically necessary. ** FFmpeg * Pulse-density modulation (PDM) Direct Stream Digital (DSD) is standard for Super Audio CD * foobar2000 Super Audio CD Decoder (based on MPEG-4 DST reference decoder) *** FFmpeg (based on dsd2pcm) * Pulse-amplitude modulation (PAM) Lossless compression * Actively used Most popular * Free Lossless Audio Codec (FLAC) ** libFLAC FFmpeg * Apple Lossless Audio Codec (ALAC) ** Apple QuickTime libalac FFmpeg Apple Music * Monkey's Audio (APE) ** Monkey's Audio SDK FFmpeg (decoder only) * OptimFROG (OFR) * T ...
