“…There does, however, exist at least one exception in the payload format for SMPTE 292M video [RFC3497] that uses a clock rate of 148.5 MHz. The reason here is that the timestamp then identify the exact start sample within a video frame.…”

“…The key point is that these use cases vary in size from two participant point-to-point sessions to multicast groups with tens of thousands (or, perhaps, even millions) of participants, vary between interactive to non-interactive, and from low bandwidth (kilobits per second) telephony to high bandwidth (multiple gigabits per second [20], [21]) video and data streaming.…”

Abstract-The Real-time Transport Protocol (RTP) supports a range of video conferencing, telephony, and streaming video applications, but offers few native security features. We discuss the problem of securing RTP, considering the range of applications. We outline why this makes RTP a difficult protocol to secure, and describe the approach we have recently proposed in the IETF to provide security for RTP applications. This approach treats RTP as a framework with a set of extensible security building blocks, and prescribes mandatory-to-implement security at the level of different application classes, rather than at the level of the media transport protocol.

“…UltraGrid has the potential to support two types of RTP payload formats: Circuit emulation (IETF's RFC 3497 [14]) and native packetization (RFC 4175 [15]). Circuit emulation packetizes and transports the SMPTE 292M signal so that it is compatible with other industrial products using HD-SDI interfaces.…”

SUMMARYThe recent growth in available network bandwidth envisions the wide-spread use of broadband applications such as uncompressed HD-SDI (High-definition serial digital interface) over IP. These cuttingedge applications are also driving the development of a media-oriented infrastructure for networked collaboration. This paper introduces imCast, a high-quality digital media platform dealing with uncompressed HD-SDI over IP, and discusses its internal architecture in depth. imCast mainly provides cost-effective hardware-based approaches for high-quality media acquisition and presentation; flexible software-based approaches for presentation; and allows for economical network transmission. Experimental results (taken over best-effort IP networks) will demonstrate the functional feasibility and performance of imCast. key words: uncompressed HD-SDI, immersive media, interactive conferencing, tele-presence, network-based collaboration
