A Review on Different Video Coding Standards

Social and network computing demands effective, offering and sparing of image data, which has dependably been an incredible test. Individuals are imparting, transmitting and putting away a great many images every moment. Video coding is a process of compressing and decompressing a digital video signal. The transmission of large size video is facing limitation due to the limited bandwidth and storage capacity. The solution for this is the video compression. In video coding for compression, the basic idea is to exploit redundant data. High Efficiency Video Coding (HEVC) is currently being prepared as the newest video coding standard of the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. The fundamental goal of the HEVC standardization effort is to enable significantly improved compression performance relative to existing standards. Thus, this paper reviews various standards and techniques and highlight the need for compression. DOI: 10.17762/ijritcc2321-8169.160414

Invasive pulmonary aspergillosis with brain dissemination in an immunocompetent host

Invasive aspergillosis is an uncommon infection, which is mainly seen among immunocompromised patients. In recent years, cases of aspergillosis involving immunocompetent hosts are increasingly being reported. Herein, we report the case of a 27-year-old man with fever, productive cough, shortness of breath, and left hemiparesis. He had suffered trauma to his head 25 days prior. Imaging of the chest showed bilateral cavitary lesions in the lungs, and neuroimaging revealed a space-occupying lesion in the right frontoparietal cerebrum. He was suspected of having an abscess or metastasis. He died on day 3 of hospitalization, and an autopsy was performed. The autopsy revealed the cause of death to be invasive pulmonary aspergillosis, with brain dissemination. Invasive aspergillosis is uncommon in apparently immunocompetent individuals, and we discuss the autopsy findings in detail

Pulmonary histopathology in fatal paraquat poisoning

Paraquat is a potent herbicide widely used in the Indian agriculture industry. Human fatality due to paraquat poisoning is not uncommon in this country. The primary effect of paraquat is on the lungs, and the resultant pulmonary damage leads to the patient’s demise. There is a high mortality rate in paraquat poisoning as the treatment is usually supportive with no known antidote. There are limited human studies that have observed the histopathological changes in lungs in paraquat poisoning. The authors have discussed the time-related histopathological changes in lungs in paraquat poisoning on autopsy subjects. The role of anticoagulants and fibrinolytic agents in the treatment of this poisoning has also been discussed
