Information on MPEG Standards

 

MPEG-4 Are we there yet? YES, see VL3400 Series.

While it's been 15 years since IPTV was invented. Radiant took a leadership role in implementing solutions primarily on MPEG-2.  Radiant’s approach resulted in multiple successful projects and solutions working in the field across multiple markets and applications. Recently, however the need and desire for reduced bandwidth and high quality video has become the next major objective for our users.  MPEG-4 seems to be the best option available to accomplish this. Today the primary use for MPEG-4 encoded video in a real time streaming application has been mostly conditional access for security monitoring applications.  Only in the past 6-12 months has MPEG-4 been looked at as a possible solution to the bandwidth puzzle.  In step with these current market developments, Radiant is again leading the way and offering multiple solutions based on MPEG 4.  Our RM1100 and V3510 series have both been positive and productive platforms for customers.

The next objective with MPEG-4 is that existing hardware requires additional fine tuning to create better quality of video. With the use of UDP and RTP traffic when a packet of data/information is lost it will not have a negative effect on video like jerking or pausing making this protocol the preferred way of streaming real-time, non buffered video. The down side to this of course is large numbers or consistent packet loss can cause video to deteriorate and adversely effect the customers original intent of high quality video at low bandwidth.  Radiant is aggressively working towards solutions such as forward error correction to attempt to increase quality of network issues or latency problems. In addition, many engineers currently feel that 2 Mbps is the lowest value that can be sent over a network link to achieve a broadcast quality feed. We are constantly asked for a product that will work over a cable modem, so we are striving to have a product that has that capability available.

As done in the past, Radiant is working hard to find a working solution that can be run at low level bandwidth to solve your application needs. With chipsets in the design and redesign cycle now offer a new solution.
