    The sliding DFT process for spectrum analysis was presented and shown to be more efficient than the popular Goertzel (1958) algorithm for sample-by-sample DFT bin computations. The sliding DFT provides computational advantages over the traditional DFT or FFT for many applications requiring successive output calculations, especially when only a subset of the DFT output bins are required. Methods fo... View full abstract»

    The biggest market for integrated circuits based on DSP is one most people do not recognize as such. These are chips that employ DSP functionality, but they are almost never programmable by the purchaser and are never sold under the DSP name. They are MPEG codecs, MP3 decoders, Wi-Fi or Bluetooth baseband chips, DVD decoders, digital camera JPEG encoders, DSL modems, cable modems, AC-3 audio codec... View full abstract»

    The previous decade has seen a variety of trends and developments in the area of communications and thus multimedia access. While individual, isolated developments produced small advances on the status quo, their combination and cross-fertilization resulted in today's complex but exciting landscape. In particular, we are beginning to see delivery of all types of data for all types of users in all ... View full abstract»

  • Video transcoding architectures and techniques: an overview

    Publication Year: 2003 , Page(s): 18 - 29

    Throughout this article, we concentrate on the transcoding of block-based video coding schemes that use hybrid discrete cosine transform (DCT) and motion compensation (MC). In such schemes, the frames of the video sequence are divided into macroblocks (MBs), where each MB typically consists of a luminance block (e.g., of size 16 × 16, or alternatively, four 8 × 8 blocks) along with cor...

    The lack of interoperable (and thus standardized) solutions is stalling the deployment of advanced multimedia packaging and distribution applications although most of the individual technologies are indeed already present. This motivated MPEG (ISO/IEC JTCl SC29 WGI I) in June 2000 to start working on the definition of enabling normative technology for the multimedia applications of the 21st centur...

    This article reviews state-of-the-art in transport adaptation techniques for mobile networks. It discusses the mechanisms for rate adaptation to combat quality degradations of speech caused by the radio links. It begins with a review of dynamic schemes for adaptation of speech encoders in cellular networks where we observe two distinct approaches to rate adaptation: network controlled and source c...

    With the growing ubiquity and mobility of multimedia-enabled devices, universal multimedia access (UMA) is emerging as one of the important components for the next generation of multimedia applications. The basic concept underlying UMA is universal or seamless access to multimedia content, by automatic selection and adaptation of content based on the user's environment. UMA promises an integration... View full abstract»
