iPod 4 Education

About RSS, iPods, and what we have learned up to now

First, the boring technical stuff

What is Really Simple Syndication?

XML based (isn't everything these days?)

Originally designed for Internal Code Maintenance

Primarily Serialized Content

Comes bundled with simplified publishing models (ie. blogs, wikis, mobblogs, etc)

Nice Concise Synopsis on RSS

 

RSS multimedia enclosures extend model to include video, audio and perhaps other data

Example code for RSS Podcasting Feed

 

Podcasting is predominantly audio

Simple to Create

Small Files

Platform independent (PC, Mac, iPod, Cell)

Portable (Device Driving Content?)

Multitasking Friendly (Workout, While Driving)

 

But Podcasting now supports Video and "Enhanced Podcasts"

Enhanced Podcasts, i.e. m4b files. Typically AAC audio combined with URL's and Images.

Video is driven by formats supported by mobile devices. Typically it is mpeg-4.

 

Some Milestones...............

NPR Program doubles online listenership in 4 weeks

List of Universities offering Podcasts of Course Lectures

iPrep offers online lectures and study guides

Adam Curry Signs Deal with Sirius to do "best of podcasts"

Infinity Broadcasting Launches all Podcasting Radio Station

Duke gives all freshmen iPods and year later holds a PodCasting Symposium

Gates says iPod success won't last

Microsoft announces compatability with the iPod in the upcoming Xbox 360

 

What do I need to listen or view?

Many RSS readers are being updated to at least understand multimedia enclosures in RSS feeds.

Apple's iTunes has an integrated Podcast Channel Manager.

iPodderX Lite (Mac)

Doppler (Windows)

Fire ANT Video Podcasting Client (Windows and Mac)

 

What do I need to record Audio?

Generally, dedicated devices are preferred for live recording. Fewer varibles, easier training.

Mobile Pirate Mode

iPod, Griffin iTalk, Radio Shack Lavalier Microphone

Pogo Products Radio Your Way LX

Edirol R1 -- High Quality 2-Track digital recorder

Laptop Recording on the Cheap

DVForge XLR USB Adapter and Microphone (either wireless or wired) makes it simple to do

And inexpensive recording software.

More details on equipment are at Wolfcast.ncsu.edu

 

"Enhanced Podcasting"

Synchronized still images and URL's with audio. Typically .m4b (preferred). Currently iPod-only, but perhaps not for long.

Art Mobs -- Guided tours of Art Museums created by students

 

ADVICE - A/V Tecnology and Design Seminars (synchronized Powerpoint slides and audio)

 

 

Tools are typically Mac based, but there is a content creation tool for Windows.

PodGuide -- Rudimentary Enhanced Podcasting tool for Windows and Mac (hint: go through short tutorial)

 

PodCastAV -- Beta Enhanced Podcast creation tool with a fairly fluid interface

 

What about Video?

Driven primarily by portable media player capability. Mpeg-4 appears to be moving ahead as dominant standard

Plenty of tools exist for all major platforms, commercial and freeware

Issues are

Limited Resolution on mobile devices -- Adequate for simple content, or standard resolution broadcast

Storage always a problem (on device and on server)

Audience Expectation -- Audience may tolerate "amateur" but adequate audio, but may shun video that does not meet professional standards

Production -- as a result of audience expectations, and due to the nature of the tools, video is more labor intensive

Wolfcast was built on code from the "Shady Dentist" (Dircaster), modded to not support PHP in writable directories (ask Everette)

Numbered at 18 active feeds (some more active than others)

Critical Aspects

Utilizes existing resources (no special server, minimal technical support)

Simplifies publication of Podcasting Content. If you have a web browser, you can publish a feed. No reliance on desktop applications or specific skills for publication.

Currently focused on publishing audio content in mp3 format. Examines

Audio only content reduces storage requirements

Deficits

Inability to do meaningful tagging of RSS feed

No GUI based file management

Restriction to just mp3 is beginning to get in the way due to support for other file formats

No "Web Face" i.e. RSS to HTML aggregator for those with no RSS reader

No Authenication for subscription (are you in my class?)

 

 

Critical Question: Build or Use for Free?

Generating feeds is not a problem. Storage is, particularly as video is introduced.

If you have space on a server, you can use a desktop tool to generate podcast feeds for you, so you don't have to write code.

Vodcaster is simple, and free, and for the Mac:
http://www.twocanoes.com/vodcaster/

For the Windows Platform, you can use:
http://www.websitediscovery.com/Free-Podcasting-Software.html

This lets you just use dumb web space somewhere (like your www4 or course locker here at NCSU).

I like for-free solutions, here is a way to use blogger.com and feedburner to generate a RSS 2.0 compliant audio feed. This is okay for audio, but if you need video you may want to consider a hosted solution, because of space issues.

http://www.podcastingnews.com/articles/Make_Podcast_Blogger.html

Edublogs.org offers 25MB of free space and access to wordpress. so you can use them as well.

Feeddigest and Google's Homepage can turn RSS feeds (including Podcasts) back into HTML

Do you need to restrict access? How about Privacast?

What's next?

Portable Digital Media Playback devices tied to media providers (Cell Phones, Sony PSP, iTunes/Video iPod)

Dumb Marketing Tie-ins (burger king).

User driven content distribution models that lead to new business models (YouTube, GoogleVideo,Veoh, etc.)

Google's Authors At Google Series

Veoh's Cult Classics

Trio Dies and Comes back as a Broadband Channel

Other Interesting things that are related

PSP is built to play back network distributed video.

Atom Films and others are taking notice.

Orb lets you broadcast your own recorded content (Windows only)

Garage Cinema Research at Berkeley is pretty cool

MobiTV -- Cellphone backed video content system

Nokia's DVB-H Digital Broadcast Initiative

 

 


 

In the end, it is content that will make it happen.
