Adaptive Video Transmission Using Residue Octree Cubes
This paper proposes a method of transmitting video streaming data based on downsampling-upsampling pyramidal decomposition. By implementing an octal tree decomposition of the frame cubes, prior to transforming them into hypercubes, the algorithm manages to increase the granularity of the transmitted data. In this sense, the communication relies on a series of smaller hypercubes, as opposed to a...
متن کاملRobust Scalable Video Transmission Using Adaptive Double Binary Turbo Code
In this paper an approach for joint source-channel coding in a spatio-temporal wavelet-based scalable coding environment is presented. The scalable quality layers are protected using a double binary turbo code for robust scalable transmission over wireless channels. In the proposed schema the double binary turbo code is used for bitstream adaptation with unequal error protection. An efficient m...
متن کاملOctree-R: An Adaptive Octree for Efficient Ray Tracing
Ray tracing requires many ray-obect intersection tests. A way of reducing the number of ray-object intersection tests is to subdivide the space occupied by objects into many nonoverlapping subregions, called voxels, and to construct an octree for the subdivided space. In this paper, we propose the Octree-R, an octree-variant data structure for efficient ray tracing. The algorithm for constructi...
متن کاملVideo transmission using USRP
The project envisions a real-time video transmission between two points using GNU Radio and Universal Software Radio Peripheral (USRP). In our project, a video signal which could be a realtime signal from a camera or simply a video file is modulated and processed by GNU radio and transmitted using a USRP. There is a USRP receiver node which receives the signal and GNU radio demodulates and re-p...
متن کاملAdaptive Video Transmission over Wireless MIMO System
There has been an interesting issue in multimedia communications over wireless system in recent years. In order to achieve high data rate wireless multimedia communications, spatial multiplexing technique (Foschini & Gans, 1998; Wolniansky et al. 1998) has recently developed as one of the most noteworthy techniques as multiple-input and multiple-output (MIMO) systems. If the channel state infor...
