The issues involved in asynchronous video transfers are introduced and brief overviews of video coding, rate control, and multiplexing, as well as delay, error, and loss control are given.
Abstract
Video transfers across IP and ATM networks have received much research attention during the last ten years. Various video services are expected in the future, enabled by the rapid development in video coding and broadband network technology. This article gives an introduction to the issues involved in asynchronous video transfers. Brief overviews of video coding, rate control, and multiplexing, as well as delay, error, and loss control are also given.

Scalable compression and transmission of internet multicast video

TL;DR: This thesis proposes a layered video compression algorithm which, when combined with RLM, provides a comprehensive solution for scalable multicast video transmission in heterogeneous networks and posit that JSSC and ALF are two manifestations of the same underlying design principle.

End-to-end delay analysis of videoconferencing over packet-switched networks

TL;DR: This study aims at showing that having a global common time reference, together with time-driven priority (TDP) and VBR MPEG video encoding, provides adequate end-to-end delay, which is below 10 ms; independent of the network instant load; andindependent of the connection rate.

User-Oriented QoS Analysis in MPEG-2 Video Delivery

TL;DR: The problem of video quality prediction and control for high-resolution video transmitted over lossy packet networks is addressed and it is demonstrated that the reachable quality is upperbound and exhibits one optimal coding rate for a given packet loss ratio.

Revealing delay in collaborative environments

TL;DR: It is concluded that revealing delays is one way in which groupware can benefit from accepting and working with the reality of distributed systems, rather than trying to maintain the illusion of copresent interaction.

MPEG: a video compression standard for multimedia applications

TL;DR: Design of the MPEG algorithm presents a difficult challenge since quality requirements demand high compression that cannot be achieved with only intraframe coding, and the algorithm’s random access requirement is best satisfied with pure intraframes coding.

RSVP: a new resource ReSerVation Protocol

TL;DR: The resource reservation protocol (RSVP) as discussed by the authors is a receiver-oriented simplex protocol that provides receiver-initiated reservations to accommodate heterogeneity among receivers as well as dynamic membership changes.

Long-range dependence in variable-bit-rate video traffic

TL;DR: It is shown that the long-range dependence property allows us to clearly distinguish between measured data and traffic generated by VBR source models currently used in the literature, and gives rise to novel and challenging problems in traffic engineering for high-speed networks.

Supporting real-time applications in an Integrated Services Packet Network: architecture and mechanism

TL;DR: This paper considers the support of real-time applications in an Integrated Services Packet Network (ISPN), and proposes an ISPN architecture that supports two distinct kinds of real time service: guaranteed service, which involves pre-computed worst-case delay bounds, and predicted service which uses the measure performance of the network in computing delay bounds.

vic: a flexible framework for packet video

TL;DR: A new video tool is described, vic, that extends the groundbreaking work of nv and ivs with a more flexible system architecture, characterized by network layer independence, support for hardware-based codecs, a conference coordination model, an extensible user interface, and support for diverse compression algorithms.
