CONFERENCE ON AV INSTALL + INTEGRATION TECH FORUM PRAGATI MAIDAN, NEW DELHI
8TH AUGUST 2015
A Conference on "Audio Video Install+ Integration (AVI+I) Tech forum" was held on 8th August 2015 at Pragati Maidan, New Delhi. The objective of the programme was to share the knowledge on advancements in Audio and Video Technologies. Mr. Anuj Verma, Assistant Professor, Department of Electronics & Communication Engineering along with four students of ECE Department (Kanupriya-8209, Deepak Kumar-8206, Shubham-8237 and Rishabh Sinha-8231) from Dronacharya Group of Institutions, Greater Noida participated in AVI+I Tech Forum. The programme was organized in three sessions.
Session - I
The first session of the program started with lecture of Mr. Mohammad Haaris, National Manager-Technical Support, Harman International Industries. He discussed the importance of HDCP & EDID. HDCP stands for High-Bandwidth Digital Content Protection, a copy protection scheme to eliminate the possibility of intercepting digital data midstream between the source and display. The format designed by Intel and licensed by Digital Content Protection uses an authentication and key exchange procedure before video and audio is presented. Products compatible with the HDCP scheme such as DVD players, Satellite and cable HDTV set-top-boxes, require a secure connection to a compliant display, the process often described as the handshake. He also discussed that due to the increase in manufacturers employing HDCP in their equipment, it is highly recommended that any HDTV we purchase is compatible with HDCP. Although most video devices support high-definition video over component output, analog connections are heading for phase out in the near future or possibly will be used for limited resolutions output. He discussed that Extended Display Identification Data (EDID) is a data structure provided by a digital display to describe its capabilities to a video source (e.g. graphics card or set-top box). It is what enables a modern personal computer to know what kinds of monitors are connected to it. EDID is defined by a standard published by the Video Electronics Standards Association (VESA). The EDID includes manufacturer's name and serial number, product type, timings supported by the display, display size, luminance data and pixel mapping data etc. This session ended with the vote of thanks by A.R. Chandrasekhar at 12:15 PM.
The Second session started by Mr. Pravin Kumar, Product Head-Visual Products Division, and Epson India PVT security-constrained optimal power flow problems. He discussed about Edge Blending Technology. He explained that Edge blending is a technique used to describe the process of visually combining several projected images to make a single seamless image. Typically, this is done to increase the size of a projected image to make a very wide image, or by combining a number of lower resolution devices together to increase the total resolution of a display. In both cases, a number of projectors are needed which are firstly overlapped and then visually joined together using an edge blending technique. This technique can be used in Auditoriums, Malls & Museums, Projection Mapping, and Simulators & Seminar Halls. The session ended at 1:45 PM.
After Lunch break, the third session started with the lecture of Mr. N.M. Mehra, Vice President-Technology & Engineering, Visual Technologies India Pvt. Limited. He gave brief idea about The 4K Revolution - What's Next? He explained that by increasing number of pixels in line image, quality can be improved. As number of pixels increases size of picture also increases. For enhancing the image quality, digitalization is necessary because it enables to use higher bit rate data transfer. The session ended with question-answers followed by vote of thanks.
