Texto completo da fonteThe ability to acquire real-time video from flight test platforms is becoming an important requirement in many test programs. Video is often required to give the flight test engineers a view of critical events during a test such as instrumentation performance or weapons separation. Digital video systems are required because they allow encryption of the video information during transmission. This paper describes a Digital Video Telemetry System that uses improved video compression techniques which typically offer at least a 10:1 improvement in image quality over currently used techniques. This improvement is the result of inter-frame coding and motion compensation which other systems do not use. Better quality video at the same bit rate, or the same quality video at a lower bit rate is achieved. The Digital Video Telemetry System also provides for multiplexing the video information with other telemetered data prior to encryption.

Texto completo da fonteTransmission of digital signals is today more frequently used than transmission of analog signals. One reason for this is that a digital signal is less sensitive to noise than an analog, another reason is that almost all signals today are handled in a digital format. This thesis describes the development of a system that receives digital video signals through FireWire. The standard for FireWire, which is a high performance serial bus, is under development. Today the standard of the bus supports transmission of data with a speed of up to 400 Mbit/s. In the future FireWire is supposed to transmit data with a speed of up to 3,2 Gbit/s. The thesis gives an introduction to the technique for FireWire and how it is implemented. It also includes a short description of digital video signals in DVCAM format.
Sandstå, Olav. "Tertiary Storage in Digital Video Archives". Doctoral thesis, Norwegian University of Science and Technology, Department of Computer and Information Science, 2004. http://urn.kb.se/resolve?urn=urn:nbn:no:ntnu:diva-305.
Texto completo da fonteIn order to efficiently manage the large amounts of video data stored in a digital video archive, computerized management systems must be developed for storing and making the video available to users. In this thesis, we study tertiary storage technologies and storage architectures for storing and retrieving digital video in video archives.
We evaluate serpentine tape as a storage medium for digital video. In order to increase the performance of storage systems using serpentine tape, we present and evaluate a detailed access-time model for serpentine tape and a novel scheduling algorithm for optimizing concurrent accesses to the tape. The scheduling algorithm is used for evaluating serpentine tape for storing images and video sequences. The main conclusion is that by using the access-time model and the proposed scheduling algorithm, it is possible to achieve significant improvements in initial latency, average access time, and the number of requests that can be served by a single tape drive.
Tertiary storage technologies including magnetic tape and DVD are evaluated for use in digital video archives. The evaluation is performed using a simulator of the storage system of a video archive. The simulation model is based on the architecture of the Elvira~II video archive server. Different configurations for the storage system are evaluated with regards to performance and cost. In the evaluation different allocation strategies, access distributions, and user loads are studied. The effect of using a cache based on magnetic disks is investigated.
The main conclusion is that the choice of architecture and storage technology for a video archive depends on the user generated load, the size of the requested video sequences, and the access distribution for the stored videos. It also depends on whether throughput, response time, storage cost, or cost per retrieved video is the main evaluation criterion. Furthermore, we show that a video archive based on DVD as the main storage technology outperforms a video archive using magnetic tape, and that including a relatively small disk cache in most cases improves the performance and reduces the total cost of the archive.
The ideas and results presented in this thesis are also useful outside the video archive context. The strategies and results are beneficial for applications that require hierarchical storage management systems for managing large data volumes.

Texto completo da fonteThis paper describes a completely integrated digital video telemetry system and analyzes several critical aspects of that system. The typical video network may consist of video source signals on the ground as well as airborne while the receive site is usually ground based. Examples of system issues which will be described and analyzed are listed below. * Multi-mode operation: It is likely that a single receive site must be able to rapidly switch between video sources having different bit rates and modes of operation. One technique to achieve this capability will be presented and discussed. * Error sensitivity: It is important that the coding compression technique be resilient to transmission errors. Techniques to achieve this robustness for both synchronization and data signals will be discussed. * Data Multiplexing: From a system point of view, it is extremely efficient to multiplex other digital signals (e.g. audio, IRIG time code) with the video signal to form a single stream for encryption and transmission. A particularly efficient multiplex technique will be presented. * Diagnostics: Video telemetry systems are more effective when they contain carefully designed built-in diagnostics. Advanced concepts for both board-level and system-level diagnostics will be presented.

Freeman, William John. "Digital Video Stabilization with Inertial Fusion". Thesis, Virginia Tech, 2013. http://hdl.handle.net/10919/23080.
Texto completo da fonteThis thesis presents a digital stabilization method that incorporates inertial fusion with a Kalman filter. The camera motion is derived visually by tracking SIFT features in the video feed and fitting them to an affine model. The digital motion is fused with a 3 axis rotational motion measured by an inertial measurement unit (IMU) rigidly attached to the camera. The video is stabilized by digitally manipulating the image plane opposite of the unwanted motion.
The result is the foundation of a robust video stabilizer comprised of both visual and inertial measurements. The stabilizer is immune to dynamic scenes and requires less computation than current digital video stabilization methods.
