Learn about significant new improvements to MPEG-2 Video coding, how this enables more services to legacy set-top boxes and receivers, and about the revolutionary new TANDBERG EN8100 Advanced MPEG-2 Broadcast Encoder. ABSTRACT Broadcasters are required by federal regulation, and locked into in practice due to the millions of consumer digital televisions (DTVs) purchased, to use the MPEG-2 Video...

The MPEG format is widely used and therefore an attractive vehicle for the distribution of video and audio material over the Internet. However, the hierarchical structure of MPEG systems complicates the task of delivering continuous, synchronized streams of video and audio in a best-effort environment (today’s Internet). If the network throws away packets on encountering congestion, the video a...

Purpose: Enalapril maleate (EPM), was used for hypertension and congestive heart failure. In this way, an innovative delivery system with mPEG–PCL was synthesized and the release profile of the EPM from the drug-loaded polymersomes was evaluated. Methods: Di-block methoxy)-poly (ethylene glycol) - Poly (caprolactone) (mPEG-PCL) copolymers were synthesized and used to prepare of polymersom...

MPEG-7 is a promising standard for the description of multimedia content. A lot of applications based on MPEG-7 media descriptions have been set up. Therefore, an efficient storage solution for large amounts of MPEG-7 descriptions are certainly desirable. MPEG-7 documents are also data-centric XML documents. Due to many advantages, the relational DBMS is the best choice for storing such XML doc...

The speed of current PCs enables them to decode and play an MPEG bitstream in real time. The encoding process, however, cannot be done in real-time. The purpose of this thesis is to produce a low-cost real-time Digital Signal Processor (DSP) implementation of an MPEG encoder. The DSP will provide an MPEG bitstream to the PC that can be saved to disk. The input to the DSP will be an analog audio...

In this paper, we present a frame-based characteristics extraction tool, which can retrieve meaningful information from MPEG-compressed bitstreams. Taking advantage of the extracted information, we present a general architecture for MPEG video transcoding, which can transcode a given MPEG video bitstream into various MPEG video bitstreams with different characteristics. We also implement an MPE...

Multimedia is gaining ever more importance on the Internet. This increases the need for intelligent and efficient video caches. A promising approach to improve caching efficiency is to adapt videos. With the availability of MPEG-4 it is possible to develop a standard compliant proxy cache that allows fast and efficient adaptation. We propose a modular design for an adaptive MPEG-4 video proxy t...

Methoxy poly(ethylene glycol) (mPEG) with molecular mass of 5 kDa activated with succinimidyl carbonate and cyanuric chloride, separately was covalently attached to human red blood cells (RBCs). Inhibition of agglutination by blood-type specific antisera (anti-D) was employed to evaluate the effect of the polymer coating. The remaining single cells after incubation with anti-D sera were cou...

رآکتور مینیاتوری چشمه نوترونی یک تحقیقاتی از نوع مخزن-استخری است که در آن اورانیم با غنای بالا به‌عنوان سوخت، آب سبک خنک‌کننده و برلیوم بازتابنده استفاده ‌شده است. هنگام بهره­برداری دمای سیال افزایش می­یابد باعث ایجاد فیدبک منفی می‌شود. بر اثر تزریق راکتیویته عین حال یکی مزایای این خصلت ایمنی ذاتی است، اضافی دسترس کاهش‌یافته زمان عملکرد کاهش می‌یابد؛ بنابراین محدودیت­های اصلی MNSR کوتاه (حدود 5...
