White Paper Compound images consist of text, graphics and natural images, which present strong anisotropic features. It makes existing image coding standards inefficient on compressing them. To solve the problem, this paper proposes a novel coding... [16 Sep 2009]
MPEG-4 Network Migration: Solutions and Benefits
White Paper MPEG-4 is a standard for video compression that allows network operators to dramatically improve digital video bandwidth utilization by roughly twice the comparable MPEG-2 industry benchmark for digital... [15 Aug 2009]
Adaptive H.264/MPEG-4 SVC Video Over IEEE 802.16 Broadband Wireless Networks
White Paper This paper presents a solution for delivering streaming video-on-demand to subscribers via an 802.16 broadband wireless access network. The solution leverages the forthcoming H.264/AVC Scalable Video Coding (SVC) scheme and a mechanism... [23 Apr 2009]
Hand Held Analog Television Over WiMAX Executed in SW
White Paper This paper describes a device capable of performing the following tasks: it samples and decodes the composite video analog TV signal, it encodes the resulting RGB data into a MPEG-4 stream and sends it over a WiMAX link. [02 Apr 2009]
Advanced MPEG-2 Encoding
White Paper This white paper introduces the advanced MPEG-2 encoding techniques featured on the standard definition DiviCom MV50 encoder from Harmonic. This sixth-generation encoder supersedes the market-leading MV45 encoder,... [01 Apr 2009]

Handling Binary Encoded XML
White Paper In multimedia applications, XML is being increasingly used to represent metadata; examples are MPEG-7 multimedia description schemes and MPEG-21 usage environment descriptions. Within the... [03 Dec 2008]
XML-Driven Exploitation of Combined Scalability in Scalable H.264/AVC Bitstreams
White Paper In this paper, XML descriptions are used representing the high-level structure of the bitstreams by relying on the MPEG-21 Bitstream Syntax Description Language standard. The heterogeneity in the contemporary multimedia... [05 Nov 2008]
Adaptive Streaming of MPEG-Based Audio/Video Content Over Wireless Networks
White Paper This paper describes a method for robust streaming of combined MPEG audio/video content (encoded either with MPEG-2 or MPEG-4/H.264) over in-home wireless networks. The paper makes use... [22 Oct 2008]
Mobile System for Video Streaming of Lectures
White Paper The paper uses the example of an international conference about e-learning technical infrastructure to describe the use of the system for broadcast of a short movie, simultaneous presentation in three auditoriums and streaming (with... [22 Oct 2008]
Data Recovery Using Improved RVLC in MPEG-4
White Paper This paper presents a low-complexity RVLC decoding scheme (including the effect of DC/AC prediction) that recovers more blocks and sometimes more MBs from error propagation region of corrupted video packets, as compared to the... [21 Oct 2008]
Using SCTP With Partial Reliability for MPEG-4 Multimedia Streaming
White Paper The MPEG-4 standard encodes a video stream in 3 different frames, I, P and B, where the P and B frames depend on the I frame. Loosing an I frame is especially bad. This paper exploits the Partial Reliability features of... [21 Oct 2008]
Experiences With MPEG-4 Multimedia Streaming
White Paper With the advent of next-generation multimedia technologies such as very-low bit rate MPEG-4 codec, multimedia streaming of high-quality video and audio has become a near-term reality. The high compression ratio and error... [21 Oct 2008]
Implementation and Evaluation of Proxy Caching System for MPEG-4 Video Streaming With Quality Adjustment Mechanism
