The fundamental issue of identifying the appropriate database items for broadcast or refrained from being broadcast have largely been ignored. In th...

SUMMARY In wired networks, broadcast and multicast transmissions can be easily achieved by data link layer (layer 2). Nevertheless, it is a big challenge to safely transfer broadcast or multicast data frames over multi-hop mobile ad hoc networks (MANETs) due to the high bit error rate, the high collision probability and the lack of acknowledgment. Additionally, most of MANET's routing protocols...

For large-scale multimedia events such as televised debates and speeches, the amount of content on social media channels such as Facebook or Twitter can easily become overwhelming, yet still contain information that may aid and augment understanding of the multimedia content via individual social media items, or aggregate information from the crowd’s response.

With increasing volumes of audio and video data broadcast over the web, it is of interest to assess the performance of state-of-theart automatic transcription systems on compressed audio data for media indexation applications. In this paper the performance of the LIMSI 10x French broadcast news transcription system is measured on a two-hour audio set for a range of MP3 and RealAudio codecs at v...

In Taiwan, there are different types of TV programs, and each program usually has its broadcast length and frequency. We accumulate the broadcasted TV programs’ word-ofmouth on Facebook and apply the Backpropagation Network to predict the latest program audience rating. TV audience rating is an important indicator regarding the popularity of programs and it is also a factor to influence the rev...
