چکیده
www.digilogicsystems.com The Wideband IF Record & Replay System has been developed using the National Instruments PXI(e) hardware platform and LabVIEW environment. For IF inputs, PXIe 7966R with 5761 adapter is used and for IF outputs, PXIe 5451 module has been used. For the Record & Replay software, various techniques like Digital DownConversion (DDC), Digital UpConversion, Streaming of data at higher rate have been used & implemented using LabVIEW. The total system has been designed and developed using COTS products and the software modules are provided as various IPs like Recording IP, Data Retrieval IP, etc.

Using SDR for Cost-Effective DTV Applications
Today’s digital TVs can provide advanced functionalities such as DVR, EPG, and PIP. They require simultaneous access to multiple channels using additional hardware resources, which increases the cost. In order to solve this problem, we propose to use wideband software defined radio (SDR) that can demodulate multiple channels on a single radio frontend. Through the SDR, we can obtain multiple ch...
متن کاملDistributed Reservation Algorithms for Video Streaming over WiMedia UWB Networks
Ultra-wideband (UWB) technologies with higher data rates and lower transmission power over shorter ranges, have enabled a new set of applications in Wireless Personal Area Networks (WPANs). For example, UWB can offer data rates 50 to 500 times higher than the current WPAN technologies such as Bluetooth. This property makes UWB a primary candidate for indoor high-speed multimedia applications su...
متن کاملEstimating the Number of Wideband Radio Sources
In this paper, a new approach for estimating the number of wideband sources is proposed which is based on RSS or ISM algorithms. Numerical results show that the MDL-based and EIT-based proposed algorithm havea much better detection performance than that in EGM and AIC cases for small differences between the incident angles of sources. In addition, for similar conditions, RSS algorithm offers hi...
متن کاملAccountable Attribute-Based Broadcast
In many broadcast applications, fine-grained access control over contents is required to provide differentiated services to users. For this purpose, the content provider may assign sets of attributes to the contents, and user access privileges are defined as logic expressions over these attributes. For example, in a digital video recorder (DVR) system, the content provider might broadcast episo...
متن کاملDMT—a Demonstration
DMT is a software demonstration tool, running on workstations, that can be used to demonstrate other software tools. The paper describes the reasons for developing DMT and the implementation of DMT. DMT simulates a video recorder/player system and provides recording, winding (forward/backward) and replaying functions. During recording, DMT records the target tool window image changes and the in...
