Ericsson and Polish telecom operator Polkomtel successfully carried out the first test of LTE Broadcast technology in Poland on August 30, streaming the opening game of the 2014 World Volleyball Championship between Poland and Serbia to 300 selected guests and journalists at Warsaw's National Stadium.
HDTV signals at 60 Hz require around 19 megabits per second to carry all the necessary information to recreate the video. This 19 Mbits is achieved by compressing the pure signal through a special high definition subset of the MPEG-2 video compression scheme and Dolby's AC-3 audio compression scheme. In fact, the uncompressed HDTV data is about sixty times larger than the compressed 19 Mbit signal!
A 19 Mbit HDTV signal fits into a standard 6 MHz frequency band used for uncompressed, analog NTSC television signals. Each HDTV broadcaster has been allotted a frequency band for their HDTV broadcasts. However, using digital compression technology, that same bandwidth can carry a single high definition signal or multiple standard resolution signals. Since a 640 by 480 resolution standard definition digital television signal is not as large as a 1,920 by 1,080 resolution signal, several of the smaller signals can supplant the single high definition one.
Imagine a one-lane road through a small neighborhood. The street can only fit one large, wide-load truck. However, it can fit two small family sedans, and it can accommodate six motorcycles. The road remains the same size so it can be used for a variety of purposes from single extra-large trucks to multiple motorcycles. The same is true of a digital television channel. It can accommodate one "extra-large" HDTV signal (1,920 x 1,080 at 60 Hz interlaced or 1,280 x 720 at 60 Hz progressive) or up to five or six standard definition 640 by 480 signals. Thus, digital television allows broadcasters to provide multiple channels of standard quality programming (similar to the quality of a DVD) or a single channel of ultra-pure, ultra-high quality high definition programming.
Presently, the major networks have voiced their support of high definition programming for prime time shows. However, any television station broadcasting in high definition may also break down their high definition channel to present multiple standard channels. In theory, a television station could broadcast five different news shows in standard resolution during the evening news hour tailoring one to each area of a city or to each county in the broadcast area for instance. True HDTV is where digital television really shines, but DTV also lends flexibility to broadcasters that has never been available before.
Radio visualisation is a catch-all name for adding pictures to radio; and I believe it's unhelpful. Doing live visualisation is difficult to do, and in many cases can harm the output of the radio programme: presenters find the cameras irresistable, and the radio listener is forgotten (yet is considerably in the majority). Just because you cando something doesn't always mean you should.
Yet, well-produced clips after the event can considerably help the shareability of radio; and also its permanence. Radio is ephemeral: broadcast and, largely, forgotten. To capture the best bits of radio, and place these on services like YouTube or Vimeo, makes it easy to share fantastic pieces of radio: and doesn't change the station sound. There is, after all, a reason why we're called radio and not 'audio television'.
With the release of Google’s recent Hummingbird algorithm update, mobile sites and strategies are in the spotlight. Here’s a closer look at what you need to know to develop the right mobile-optimized content marketing strategy for your business.
"In this video I look at video streaming using the Beaglebone black using: RTP, UDP unicasting, and UDP multicasting, which allows one to many streaming. In all of these examples I used the VLC media player to display the video data. The final part of this video goes on to describe how you can build your own software implementation that can display the data using LibVLC and the Qt framework."

Dutch telco, KPN, has become the first network operator in the Netherlands to conduct live tests with LTE Broadcast for mobile TV. KPN worked with Ericsson in collaboration with Qualcomm Technologies, Samsung and IBM.
The trial took place on Saturday 3 May in the Amsterdam Arena stadium during the football match between teams Ajax and NEC.
35 years after the first Sony Walkman shipped, today's music player still has essentially the same set of controls as that original portable music player. Even though today's music player might have a million times more music than the cassette player, the interface to all of that music has changed very little.
