In this time of modern technology, where the links of the modern world have been intensified, the Internet has become a powerful tool in acquiring information. One of the most recent trends in cyberspace is broadcasting audio and video clips. Thus, certain websites like myspace.com, where unsigned bands promote their music, and youtube.com, where people all over the world publicize homemade videos, have become familiar names for many.
As media streaming via the Internet becomes more and more popular, cellular phones have also become more powerful and wireless connections increase by the minute. There emerges a need to bring together the available technologies to make life better and fulfill the promise of development. The study entitled “Adaptive RTP-Compatible Audio Streaming for Handheld Clients (ARCASH)” makes an audio streaming application based on cellular technology interoperate with Real-Time Transport Protocol (RTP), the standard in real-time audio streaming on the wired level.
“Interoperability is the keyword,” says Ms. Joyce Avestro, the author of the study. She stresses that interoperability is an important issue to consider especially when sharing data from different implementations. Interoperability, by definition, is the ability of software and hardware on different machines from different vendors to share electronic files. The whole scheme of ARCASH can be seen in the figure below.
The Avestro experiment has discovered that a wireless client can still successfully receive and play audio clips such as music, interviews and dialogues sent by the RTP server. There is no significant difference in audio quality among the wireless and the wired connections.
