  1. 1. The podcaster uploads media files (MPG3 or MPG4) to the server.

  2. 1. The podcaster uploads media files (MPG3 or MPG4) to the server. 2. The podcaster then uploads an XML file to the server which provides a podcasting ‘channel’ and contains links to the media files.

  3. 1. The podcaster uploads media files (MPG3 or MPG4) to the server. 2. The podcaster then uploads an XML file to the server which provides a podcasting ‘channel’ and contains links to the media files. 3. The podcaster provides users with the link to the XML document, which the user enters into their RSS client (eg iTunes) to subscribe to the podcasts on this channel.

  6. Media Files for PodcastingMP3 (MPEG-1 Audio Layer 3) Audio • MP3 (MPEG-1 (MPEG – Moving Picture Experts Group) Audio Layer 3) is the most popular digital audio encoding and lossy compression format, designed to greatly reduce the amount of data required to represent audio, yet still sound like a faithful reproduction of the original uncompressed audio to most listeners. The MP3 format has been in use since 1994.

The MP3 format has been in use since 1994. • Because MP3 is a lossy format, it is able to provide a number of different options for its "bit rate" — that is, the number of bits of encoded data that are used to represent each second of audio. Typically, rates chosen are between 128 and 320 kilobit per second. By contrast, uncompressed audio as stored on a compact disc has a bit rate of 1411.2 kbit/s (16 bits/sample × 44100 samples/second × 2 channels).

  9. Media Files for PodcastingMPEG-4 Video • MPEG-4 is the global multimedia standard, delivering professional-quality audio and video streams over a wide range of bandwidths, from cell phone to broadband and beyond. • MPEG-4 was defined by the Moving Picture Experts Group (MPEG), the working group within the International Organization for Standardization (ISO) that specified the widely adopted, Emmy Award-winning standards known as MPEG-1 and MPEG-2. Hundreds of researchers around the world contributed to MPEG-4, which was finalized in 1998 and became an international standard in 2000 and included in QuickTime in 2002.

The MPEG-4 video will usually have the extension .m4v

  20. FTP (File Transfer Protocol ) • FTP or File Transfer Protocol is a commonly used protocol for exchanging files over the internet. • There are two computers involved in an FTP transfer: a server and a client (user’s computer). The FTP server, running FTP server software, listens on the network for connection requests from other computers. The client computer, running FTP client software, initiates a connection to the server. Once connected, the client can do a number of file manipulation operations such as uploading files to the server, download files from the server, rename or delete files on the server and so on. • Filezilla is an example of an FTP client
