InFILE Enhancing The Value Of Content
Cavena supports global content, says Henrik Moberg, MD, Cavena
Without an effective means of language transfer, programming is effectively restricted to the markets which speak the language in which the original programming was made. Providing an alternative language, especially via subtitling, allows the geographical distribution of that content to be dramatically extended. Subtitling has a number of valuable advantages over audio dubbing. Significantly, it is much cheaper, but is also more flexible, as additional languages can easily be added to cater for different markets. So how does the process of subtitling work? There are two separate stages to subtitling, preparation and transmission. Subtitle preparation is a specialised form of translation. The subtitler creates the file on a subtitle by subtitle basis, and times the in and out cues of each subtitle with reference to the programme’s timecode. This is done using specialised subtitling software such as Cavena’s well-proven T e m p o system. This software has been developed over many years of experience in the subtitling industry, and allows rapid and efficient subtitle preparation. Once the subtitle file has been created, it is stored in a variety of industry standard file formats, depending on the final use of that particular file. One of the advantages of subtitling is that the same file can be used, with only minor modifications, in a range of different transmission options. The second part of the subtitling process is transmission, for which there are two categories, open and closed captioning. Open captioning is the simplest method. Under timecode control, each subtitle is played out using a transmission controller and a subtitle inserter such as Cavena’s STU system driving a Cimpress subtitle inserter. The subtitling is inserted directly into the video, creating a high quality output, and this type of subtitling is ideal for customising programming intended for just one language territory. Cavena’s Cimpress system is now available in SD standard and soon

in HD. A l t e r n a t i v e l y, closed captioning can be used. This is a range of methods, but all have a common principle. The subtitling is sent, under automation system control, as a data stream along with the programming. The subtitles are then decoded and displayed locally by the set top box, TV or cable head end. The advantage of this is that multiple languages can be transmitted simultaneously for satellite transmissions over a wide geographical area. Again, Cavena’s combined STC and STU systems are suitable for multiple language transmissions in a wide range of output formats. Cavena offers a wide range of subtitle preparation, transmission, archiving and control systems. ■ 27
