Trends in Ip Video Transmission
The main problems in transmission of video data is size of the files and sensitivity of video streams to time delays. Currently and in the foreseeable future, H.264 algorithms ensure the best results – the lowest bandwidth and disc space requirements, the shortest download time. The parameters are about 30% better than in the case of MPEG-4 ASP compression. The newest codec is used by the most technologically advanced companies using mainly Texas Instruments platform (DaVinci).
Market research shows that in 2011 H.264 will catch up with MPEG-4 and then become the undisputed leader.
DIPOL has been cooperating with ACTi since 2005. For the three years the company – well known and highly regarded in the world – has also won recognition in Poland. In 2007 DIPOL was the largest distributor of ACTi products in Central and Eastern Europe.
It’s time for revolutionary changes in video surveillance. The main pillars are: use of megapixel cameras, implementation of MPEG-4 compression with H.264 codec, image analysis. ACTi is the leader of the mainstream. The company offers megapixel cameras, both with H.264 compression and proprietary NVR system.
During the event ACTi invited the visitors to the seminar “H.264 megapixel solutions – a new era in video surveillance”. A very interesting and profound lecture was delivered by Mr. Juber Chu, the CEO of ACTi Corporation. It included forecasts for market share of megapixel cameras and H.264 compression on the CCTV market.
ACTi offers many models of CCTV cameras, especially those of megapixel resolution. These cameras, both for indoor and outdoor applications, feature stable operation and high image quality. They stand out with unrivaled quality / price ratio.
During the latest IFSEC in Birmingham the company presented its newest 3 Mpix IP camera TCM-5300 with SONY 1/3” CCD, implementing H.264 compression and dual stream. We will offer the camera soon.

The G5CD, by KG2RG I needed something for 20M, and we are all out of insulators here. However, my 10 year old son Andy and I decided to have a little fun. While fooling around, we noticed that a PL259 female was the perfect size of the hole in the center of a CD. The female connector screwed into the center hole of the CD and fit tight and perfect. So we decided to have fun with this, and used it as the center conductor for our 20M meter dipole. So remember boys and girls, now that you all have iPods, don’t throw your old CD’s in the trash. Instead, become ham operators and use them to make antennas. lol. This video clips is 2 stations we were able to work on 20 meters.The first station is the special events station W6N. The second station is the big DX station out of Brazil, PY2JY, Fernando. Check out his station at this link. www.iz1gcz.com
