Networking of MPEG-4 content is the topic of ongoing standardization efforts in the ISO MPEG and IETF. In this paper, we describe a complete architecture for the transport of MPEG-4 content over the Internet. The MPEG-4 concept of separation between applications and delivery mechanism is preserved. The use of well-established Internet protocols, such as the Real Time Protocol (RTP) and the Real...

The purpose of this page is to provide an overview of the MPEG-1 and MPEG-2 video coding algorithms and standards and their role in video communications. The text is organized as follows: The basic concepts and techniques which are relevant in the context of the MPEG video compression standards are reviewed first. In the following the MPEG-1 and MPEG-2 video coding algorithms are outlined in mo...

The emerging MPEG-4 standard specifies an objectbased audiovisual representation framework, integrating both natural and synthetic content. Tools supporting three-dimensional facial animation will be standardized for the first time. To support facial animation decoders with different degrees of complexity, MPEG-4 uses a profiling strategy, which foresees the specification of object types, profi...

|With the success of the Internet and exibility of MPEG-4, transporting MPEG-4 video over the Internet is expected to be an important component of many multimedia applications in the near future. Video applications typically have delay and loss requirements, which cannot be adequately supported by the current Internet. Thus, it is a challenging problem to design an e cient MPEG4 video delivery ...

This study aimed to develop a cationic nanosuspension of chitosan (CS) and methoxy poly(ethylene glycol)-poly(ε-caprolactone) (MPEG-PCL) for ocular delivery of diclofenac (DIC). MPEG-PCL-CS block polymer was synthesized by covalent coupling of MPEG-PCL with CS. The critical micelle concentration of the MPEG-PCL-CS block polymer was 0.000692 g/L. DIC/MPEG-PCL-CS nanosuspension (mean particle siz...

Systemic administration of chemotherapy for cancer often has toxic side effects, limiting the doses that can be used in its treatment. In this study, we developed methoxy poly(ethylene glycol)-poly(caprolactone) (MPEG-PCL) micelles loaded with curcumin and doxorubicin (Cur-Dox/MPEG-PCL) that were tolerated by recipient mice and had enhanced antitumor effects and fewer side effects. It was shown...

We are using MPEG-4 technology to build applications to be used in real environments. One of these applications allows for teacher to send real-time lessons to this/her students or to record them. The TeleLearning System under development includes: a) on the teacher side: a recording workstation with two cameras, microphone, specific MPEG-4 software; b) an IP network or an MPEG-2 TS satellite l...

Digital television is a reality today, but multimedia communications, after years of hype, is still a catchword. Lack of suitable multi-industry standards supporting it is one reason for the unfulfilled promise. The MPEG committee which originated the MPEG-1 and MPEG-2 standards that made digital television possible is currently developing MPEG-4 with wide industry participation. This paper des...
