AbstractWider dissemination of medical digital video libraries is affected by two correlated factors, resource effective content compression that directly influences its diagnostic credibility. It has been proved that it is possible to meet these contradictory requirements halfway for long-lasting and low motion surgery recordings at compression ratios close to 100 (bronchoscopic procedures were a case study investigated). As the main supporting assumption, it has been accepted that the content can be compressed as far as clinicians are not able to sense a loss of video diagnostic fidelity (a visually lossless compression).Different market codecs were inspected by means of the combined subjective and objective tests toward their usability in medical video libraries. Subjective tests involved a panel of clinicians who had to classify compressed bronchoscopic video content according to its quality under the bubble sort algorithm. For objective tests, two metrics (hybrid vector measure and hosaka Plots) were calculated frame by frame and averaged over a whole sequence.

Rijndael Algorithm

Three technologies can be used for content protection in DVB-H; IPSec, SRTP and ISMACryp. ISMA Encryption and Authentication is one of the three chosen technologies for service protection in DVB-H (Digital Video Broadcasting - Handheld), the TV system for portable handheld devices. This paper deals with modification in ISMACryp. The ISMACryp is encoded with MPEG-4 video and MPEG-4 AAC (advanced audio coding), while leaving all structural data as it is. Two modes of ISMACryp are available; the CTR mode (Counter type) and CBC mode (Cipher Block Chaining) mode. Both modes of ISMACryp is based on 128-bit AES algorithm. AES algorithms are more complex and require larger time with more clock cycles for execution. This paper is being first simulate and implement existing ISMACryp using 128-bit Rijndael algorithm and then modified it with KASUMI algorithm that will be provided lower number of clock pulses with lower execution time. The simulation is done in Matlab and implementation in TMS320C6713 DSP kit.

User Navigation

Video browsers provide an environment in which a user may navigate digital video content. They are therefore an important application for improving access to digital video resources. We apply a general framework for navigation, proposed by Spence (1999), and consider existing proposals for video browsers made within the research literature within the context of the framework. We then use this analysis to derive a number of principles that reflect the requirements for supporting and enhancing the user in the digital video navigation task.
