, BIRTV2005, media asset management - Network Radio and Television

BIRTV2005, world famous radio and television major manufacturers have brought their latest products, patiently with the Chinese market practitioners with a new term to display the respective solutions for the future, so much were dazzled, dizzying feeling. In the field of sports television, EVS industry leading companies and manufacturers are doing all ORAD companies to show us they have made in this area for their achievements and their confidence in the future.

Here, focusing on what they raised for the sports broadcast some new ideas and practices.

An EVS's IPS EVS company earlier in the broadcast industry is a slow motion drive systems has gained world renown for. In 1994, EVS company was born, the company's start-up phase of the computer age with all sorts of "garage story," similar to the broadcast of several young people to be rewritten using slow motion video shows the history of television. 1996 Atlanta Olympic Games is a turning point for EVS business. Founder, software technology expert Laurent? Mange to sell their technology to the United States. Mange Paizhuoxiongfu that when I went to sleep next to the camera to connect the server to ensure that broadcast foolproof. Year in the world to receive the Olympic broadcast television, for the first time "a clear, perfect slow broadcasting technology." Paris 1998 World Soccer Cup, mange to find the Dutch Philips company, ask them to produce a 75 frame per second film camera?? It higher than 3 times the speed of the camera. Philips think that this camera costs too high, there is no market. EVS company then bet, they pay 20 units to the Philips customized "super slow motion camera", with the company's slow-motion cameras and broadcast systems to Paris. French organizers of the World Cup experience behind the lens of their high quality, immediate orders to buy. The result is that the Athens Olympics in 2004 when the 1000 stadium cameras, the use of EVS technology accounts for 1 / 5, that is, 200.

EVS company is not satisfied with the achievements, this BIRTV, they proposed IPS (IntegratedProductionSystem) show that they want to participate in the concept of including live sports, studio post-production before the whole process, including television production ambition. Their goal is to EVS server with the software, create a true collaboration-based tapeless workflow, unified production environment, including material acquisition, cataloging, media asset management, material view, edit all the process until the broadcast.

1. Scene log keeper and media asset management capabilities

This is the EVS in its new software to add new functionality IPDirector, live in slow motion is for the sports landmark. Why? Look at the past, slow-motion live sports production, we can see past the technical means of storage of the slow-motion clips is not managed at all, and storage because they can not retrieve fragments of fragments re-use efficiency is very low. The new IPDirector, allowing the notes written a special staff to do the race when the code based on the notes written record, so that each fragment of a stored key words are accurate, can be used to retrieve the fragments. For example, the soccer match, when the time code point 12:05:30 Party goals, log keeper staff code point will be given this time 12:05:30 such as "goals," "goal team" "header" and other key words, while this time, networked EVS slow motion all the hard yards at this time point included slow-motion clip store will automatically be given the key words. With this feature, all stored in slow motion clip are searchable, and greatly improved the efficiency of fragment re-use, reproduce and make the game exciting technical analysis becomes possible, greatly expanding the sport live content space.

2. Big event broadcast content IBC System Center

2005 FIFA Confederations Cup in Germany shortly before the success. EVS broadcast company for this event provides a complete set of the central server system, the system includes input, multi-signal recording, viewing, archiving, editing full functionality. According to information provided by EVS, the central server system including one with 6 inputs and 6 outputs, a total of 4.5TB storage capacity (240 hours of recording) the central server. This year's Confederations Cup

total of 16 games, each game included within the broadcast signal in the distribution of IBC are: Radio International signal (BIF), CleanInternational Feed (CIF), A special camera signal team, B team dedicated camera signal, bench dedicated camera signal, and the wonderful scene from the independent replay camera signal. Wonderful lens signal broadcast by the LSM operators in car production, the operator, the 6 networked HDXT [2] server to access the material.

The central server system includes two sets IPLogger workstations, providing the signal associated with the electronic entry form. One of the IPLogger for the first 5-input signal, another one for the material clip. Each entry is associated with the reference time code and include up to 5 keywords which broadcast from a host institution from the list provided by HBS, but also allow the importation of 'freetext' descriptions. In addition, multiple signals IPLogger in the entry for the BIF and will be automatically associated with all other 4-way signal. System uses a central SQL data sets from two IPLogger inventory data.

4 were operational staff to use the 4 sets IPBrowser workstation. These workstations can access the database, the database stores all the information from the input table. Operator can select the appropriate material or for broadcast, or for further editing. Operator can then play the selected material (SDI signal with embedded audio), feed to AvidNLE non-compiled site, but also the transmission network through XNetNetwork to Xfile media server. In the transfer process, also used TelestreamFlipFactory codec to convert material Avid file format for editing.

Finally, the 6-channel input signals and a database of all events are archived in the mobile hard disk, making the content of HBS can be restored at any time in the future to re-synchronize with the database content.
