  • Dynamic Circular Buffering: A technique for equilibrium gated blood pool imaging
    Computers in biology and medicine, 1996
    Co-Authors: Juan José Vaouero, H. Rahms, Michael V. Green, Francisco Del Pozo
    Abstract:

    Abstract We have devised a software technique called “dynamic Circular Buffering” (DCB) with which we create a gated blood pool image sequence of the heart in real time using the best features of LIST and FRAME mode methods of acquisition/processing. The routine is based on the concept of independent “agents” acting on the timing and position data continuously written into the DCB. This approach allows efficient asynchronous operation on PC-type machines and enhanced capability on systems capable of true multiprocessing and multithreading.

  • efficient channel navigation using Circular Buffering algorithm in digital tv
    IEEE Transactions on Consumer Electronics, 2008
    Co-Authors: Yoonhee Choi, Yeongkyeong Seong
    Abstract:

    Despite the many advantages in digital TV, users get into difficulties when they navigate channels to find their preferred programs. This is because the number of channels is much more and the channel zapping speed is much slower in digital TV than in analog one. There have been many efforts to reduce the channel zapping delay in digital TV. However, the reduction of channel zapping delay is limited by the nature of digital TV system. In this paper, we propose alternative approaches that enable the efficient channel navigation in digital TV. The first approach is to hide a channel change delay. This approach is helpful when the user wants to navigate channels by pressing up/down buttons in a full screen mode. The second approach is to show multichannel mosaic screen. This is helpful when the user wants to navigate channels by pressing four-way buttons while watching preview videos. In this paper, we propose a Circular Buffering algorithm (CBA) and show that, with help of the CBA, hiding channel change delay and multi-channel mosaic screen can be feasible in the system with limited resources. Simulation results show that the proposed methods give users high satisfaction in channel navigation.

  • A Circular Buffering Algorithm for Hiding Channel Zapping Delay in a Digital Television
    2008 Digest of Technical Papers - International Conference on Consumer Electronics, 2008
    Co-Authors: Yoonhee Choi, Yeongkyeong Seong
    Abstract:

    In this paper, we propose a new method for hiding the channel change delay by efficiently utilizing multiple tuners. One tuner is used to capture a channel being watched and the others are used to buffer other channels. In order to raise tuner usage efficiency, each Buffering tuner circulates multiple channels and buffers the A/V stream. The channel change delay is hidden by displaying a buffered A/V stream during the channel change delay. Experimental results showed that the proposed algorithm gave higher user satisfaction results when compared with other methods.
