The end of last year saw Teradek step up the game even more in the HD wireless monitoring world, with its announcement of The Bolt, a wireless HD-SDI monitoring system. The first thing that struck many on its launch was the size of both the transmitter and the receiver.
With respect to monitoring, particularly for multiplatform content delivery, how can our facility straddle the divide between baseband and file-based signals? The media industry as a whole is moving toward multiplatform content delivery.
The very first analytical electronic instrument, developed in the late 1890s, was the oscilloscope. This used a cathode ray tube (CRT) to paint a graph of voltage on the Y axis versus time on the X axis. Once television became a practical reality in the 1930s, the same instrument was applied to the video output from the camera and became the very useful waveform monitor.
One of the major challenges facing broadcasters and content producers today is quality control. In the traditional model QC was performed by skilled viewers in real time, watching the content on a good monitor alongside a waveform monitor and audio meters to ensure the technical parameters were optimised.
What are the most important things to monitor in a busy broadcast environment? We asked PHABRIX, one of the UKs leading test and measurement companies to list their top 10.
Broadcasters once were able to transmit a signal up on the satellite and worry only about that feed. Now, with the growth and diversification of audio video (A/V) service handoffs, the points at which feeds enter the facility or are sent out to downstream targets such as cable operators, pay-TV services and other service providers, broadcasters have many more feeds to monitor.
In shooting 3D you naturally have two cameras and two lenses: albeit, there are some weird and wonderful single lens/single sensor contraptions out there. This usually means there are any number of ways each camera lens combination could be producing images with minor are major signal level differences. If these level differences are not dealt with on-set or in post-production, they could lead the visually objectionable artefacts in 3D portrayal.
Video monitors have always been a critical component in any broadcasting operation but they have evolved significantly as the industry-wide migration from analog broadcast to digital SD and HD has placed new demands on the monitoring function.
For broadcasters and content origination facilities, a single issue with content or within the transmission chain can have an impact on millions of viewers. In some cases this can even lead to large financial penalties and affect commercial contracts. To guarantee uptime, minimize disruption of broadcast services, and keep revenue streams flowing, operators need to maximize the speed with which they can identify and resolve programming errors.
Because the quality and bandwidth-efficiency advantages of digital over analog methods have made digital transport preferred, the world continues its migration to an all-digital approach to delivering video signals from the studio through distribution networks to the end-viewer. As with any new technology, adopting and integrating digital video delivery brings new and diverse challenges challenges that may affect video quality and delivery reliability in unexpected (and undesired) ways.
The new R&S®DVMS1 and R&S®DVMS4 DTV monitoring systems keep track of the quality of digital TV signals they detect all relevant errors at the RF and transport stream levels. They provide parallel monitoring of up to four signals and carry out in-depth signal analysis. These capabilities combine with an ultra-compact size of just one height unit and an attractive price, which makes the systems unique on the market.
ATG Broadcast recently completed a major SD to HD upgrade for Arqiva broadcast transmission centre at Gerrards Cross, Buckinghamshire. The expanded system enables Arqiva to process and transmit four fully-operational 1080i HD channels as well as six new SD channels. It includes the installation and equipping of a server-based ingest suite, playout assembly facilities and four presentation desks.
With the rapid evolution of the industry, new technologies must offer users both value and performance in the short term, as well as the promise of continued utility in the long term.
OLED stands for Organic Light Emitting Diode. OLEDs are relatively simple in structure, made up of an electrically active organic material sandwiched between an anode (a electron-releasing electrode) and a cathode (an electron-receiving electrode).................
A number of years ago Hamlet gave itself the impossible task of developing the worlds first 3G, HD and SD capable, video and audio measurement and monitoring instrument that would provide, particularly location users, a wealth of functionality and be held and operated in one hand.
In Parts 1-3 we introduced IPTV as an emerging broadcast technology, and discussed some of the technical challenges involved in successful delivery of IPTV services. We saw how the complexity of IPTV networks and the trade-offs in technology types can provide further challenges in delivering high QoS and QoE in IPTV delivery.
In this part we will begin to explore how to test IPTV systems
The broadcast environment has gone through enormous change over the last decade, creating challenges in the management, storage and broadcast of material. Factors contributing to these challenges include the increase in the number of channels with the move to digital, the introduction of various aspect ratio and video standards with the transition to HD, and the necessary evolution from tape to file-based workflows.
To maintain differentiation in a competitive triple play market, the key operational challenge for telecommunications operators is how to efficiently deliver superior quality of service (QoS) levels.
