Transfer of Multimedia data through Police Radio Sets
Abstract : This article deals with multimedia data, which combines basic functions with high quality graphics, sound, video and animation and definitions of multimedia. Also deals with multimedia characteristics, network technology – Ethernet, Provisioning and ATM, bandwidth needs and multimedia networking along with data transfers protocols. Right issues for multimedia content like ownership, general right issues, use of photographs, film clips, music works have been discussed. Also multimedia delivery has been discussed with applications of multimedia. Several implications of bandwidth for large transmission have been explained. Multimedia applications are also highlighted in this article along with the patent issues for multimedia products.
? In this paper, the existing architectural elements supporting real-time data transmission over the Internet.
? Effective implementations of such systems require a thorough understanding of both the network protocols and the coding systems used for compressing the signals to be transmitted in real-time.
? In depth knowledge of the underlying signal processing methods are often needed for effective use of the existing protocols and extending them for future applications.
? Multimedia data stream is usually bursty. Just increasing the bandwidth will not solve the burstiness problem.
? Without careful design there can be serious problems in quality of service in real-time multimedia delivery, problems suggesting negotiation both beforehand and in real time.
? Some new transport protocols must be used to take care of the timing issues so that audio and video data can be played back continuously with correct timing and synchronization.
• This feedback in reception, quality is an integral part of the RTP protocol and it is intended to be used for congestion and flow control purposes as well as network performance input for the adaptive coding applications.
• Design may borrow from the material already published and available in the archives, and it will deliver new documents, articles, and material to be included in the archives.
• They provide powerful operations to store and retrieve the multimedia data objects while insulating the programs from the specifics of the new storage devices and the plethora of data formats.
? Servers are forced to retransmit data to clients, further congesting the network and degrading performance.
? While ethernet’s single fat pipe approach enables high performance for single applications, it prohibits multiple applications from sharing bandwidth simultaneously.
? Caching of frequently used data can help efficiency, but not all multimedia applications so benefit. To accommodate these characteristics, techniques used by the telecommunication networks include compression of data and methods of timing the transmission and replay of multimedia.
