White Paper WHP 158 Download
Delivery of broadcast content between media organisations using file transfer is becoming an increasingly attractive alternative to the physical movement of tapes, films or disks. However, widespread adoption of file-based delivery, especially over public networks such as the Internet, requires the adoption of secure, reliable and interoperable solutions. This while paper outlines the work of Pro-MPEG Forum in developing codes of practice in this area, including an overview of the Media Dispatch Protocol (MDP): a standards-based means of automating and managing deliveries. Case studies of the implementation and use of MDP are presented, together with an investigation of transfer performance and a discussion of security best practice. This white paper is a revised version of a paper from the International Broadcasting Convention in 2006 (orginal title 'File-based delivery using the Media Dispatch Protocol'). This version includes information about relevant activity in the following year, including the standardisation of MDP, further research studies, and a consideration of how this work relates to the BBC's current file delivery agenda.
