Media processors are instrumental in bridging the gap between computers and consumer electronics. Currently, they are used mainly to enhance the multimedia capabilities of PCs. Shortly, we may also expect to see their application in consumer electronics products that require a high degree of flexibility or interactivity. A typical media processor like the new chip described here’ uses a mixture of concepts from function-specific implementations, DSPs and general purpose processors. It can fulfil a variety of purposes in a ‘multimedia-enhanced’ TV platform. INTRODUCTION Multimedia has been the ‘hottest’ subject in the computer market for the last few years. Graphics, sound, and still and moving pictures greatly enhance users’ appreciation of their PCs. With such multimedia applications, computers enter an area that was formerly the exclusive domain of consumer electronics. In addition to the multimedia experience, the traditional PC assets of interactivity and customization still hold a competitive edge over consumer electronics equipment. On the other hand, the priceperformance ratio of consumer electronics equipment, i.e. the audio and video quality per dollar, is an order of magnitude better than that of current computer-based multimedia solutions. In addition, the robustness and easeof-use of consumer equipment is high. We expect to see a growing number of products that mix typical PC and consumer functions. Examples are interactive set top boxes, cheap network computers, and televisions with Internet browsing capabilities. For these products to be successful, they must offer the best of both worlds, i.e. they should be able to run many different multimedia applications with high quality and at low cost. To achieve this apparently unrealistic goal, it is necessary to reconsider the traditional approaches to product implementation, i.e. for PC manufacturers the general purpose processor based implementations, for consumer 1.

媒体处理器在弥合计算机和消费电子产品之间的差距方面起着重要作用。目前，它们主要用于增强个人电脑的多媒体功能。不久，我们也可以期待看到它们在需要高度灵活性或交互性的消费电子产品中的应用。一个典型的媒体处理器，比如这里描述的新芯片，混合了特定功能实现、dsp和通用处理器的概念。它可以在一个“多媒体增强”的电视平台中实现各种目的。在过去的几年里，多媒体一直是计算机市场上最热门的主题。图形、声音、静态和动态图像极大地提高了用户对pc的欣赏。有了这样的多媒体应用程序，计算机进入了一个以前只属于消费电子产品的领域。除了多媒体体验，传统的个人电脑的交互性和定制化仍然比消费电子设备具有竞争优势。另一方面，消费电子设备的性价比，即每美元的音频和视频质量，比目前基于计算机的多媒体解决方案要好一个数量级。此外，消费类设备的稳健性和易用性也很高。我们预计将会有越来越多的产品将典型的个人电脑和消费者功能结合在一起。例如交互式机顶盒、廉价的网络计算机和具有Internet浏览功能的电视。这些产品要想取得成功，就必须兼而有之，也就是说，它们应该能够以高质量和低成本运行许多不同的多媒体应用程序。为了实现这个显然不现实的目标，有必要重新考虑产品实现的传统方法，即PC制造商基于通用处理器的实现，消费者1。该集成电路的商用名称为TMlOOO(以前仅称为tm1)，用于电子制造商的固定功能实现。媒体处理器是这个市场的一个有吸引力的选择:它们提供了一个完全软件可编程的高性能解决方案，价格实惠。在全文中，我们将详细阐述媒体处理器、通用处理器、可编程dsp和特定功能实现之间的关系。新媒体处理器家族最近发布了新媒体处理器家族的第一款产品;衍生产品正在开发中。新芯片[1,21]由以下组件组成:一个非常强大的VLIW DSP-CPU，它运行多媒体应用软件的大多数重要部分，通常位于一个小型实时操作系统dma驱动的多媒体输入和输出单元之上，该单元格式化数据vld协处理器的VIDEO IN

With the growing popularity of Internet and Virtual Reality (VR), more and more applications, for example, VRML browsers and 3D graphics network multiplayer games, require 3D graphics capabilities over network. This paper presents a 3D graphics library written in Java to satisfy this requirement. Performance evaluation is especially addressed for further studies in developing 3D graphics applications over network. Furthermore, we have also developed a network library and combined it into the 3D graphics library, so that this library has network capability and others can develop 3D graphics network multiplayer applications based

Symbol timing offset in OFDM systems does not only induce intersymbol interference (ISI) but also causes phase rotation of the signal constellation of the receiver FFT output, which degrades system performance. In this paper, we describe a patent-pending coarse and fine symbol timing recovery algorithm for OFDM systems which, unlike previous algorithms [l-51, does not require carrier synchronization nor supplementary pilot signals for proper operation.

A new algorithm using property restoral approach for adaptive blind equalization of QAM signals is proposed. According to residual intersymbol interference (HI) levels at equalizer output, the proposed algorithm adopts a single-level radius or a multi-level radius to form the error signal to be minimized. Thus, it is possible to reduce the steady-state error and improve the convergence speed of conventional property restoral algorithms. Introduction The property restoral approach is a widely used blind equalization technique. Instead of using the training sequence the property restoral approach identifies an invariant property of the signal of interest and then uses it for adapting an equalizer. However, the performances for steady-state and blind convergence of conventional property restoral algorithms degrade when they are extended to high-order QAM constellations. In this paper, the problems of conventional property restoral algorithms are formulated, and a novel blind equalization technique based on property restoral approach is presented.

Compressed bitstreams are, in general, very sensitive to channel errors. For instance, a single bit error in a coded video bitstream may cause severe degradations on picture quality. Therefore, error concealment is needed at the receiver for picture replenishment. Error concealment algorithms attempt to repair damaged portions of the picture by exploiting the spatial and temporal redundancies in the received and reconstructed video signals. In this paper, we utilize spatially correlated information for error concealment by performing spatial interpolation based on a large local neighborhood of surrounding pixels, and restore image edges that are continuous with those present in the neighborhood. Although other spatial interpolation techniques generate blurring effects, out proposed method has shown no blurring.

A proposed encoder supports NTSC and PAL systems. I n addition, it also permits PALplus standard mode compatible to16.9 wide screen on a 4:3 screen. I n order for this to be realized, vertical and horizontal synchronous timings are fully programmable and the encoder is designed in systolic pipelined architecture with double pixel clock to increase an internal processing speed Also, we have mainly concentrated on cutting down area of the encoder as much as possible. Submodules like letter-box converter, color converter matrix, low pass jilter, interpolator, and color modulator have area saving architectures. The encoder can accept RGB and YCbCr as the input pixel signal type in the speed of 10-1SMpps. Outputs are a Y/C (S-video) signal and a composite signal .We have modeled the encoder in Yerilog-HDL and verified its operation in each mode with C-language based program.
