bittorrent

Podcasting is now far, far easier and cheaper even than I’d imagined — even for complex productions. I’ve been experimenting. Here’s a very quick summary of what I’ve learned so far about doing this on a Mac, my platform of choice.

Now if your podcast is just you talking then you can take a much simpler approach. Read no further.

However this investigation was inspired by the “live recording” of the 2web Crew. Having an audience contributing comments and questions via text chat created an interesting dynamic — similar to talkback radio but less formal. I wanted to explore further.

The technical challenge is combining all of the audio elements before the audio or video stream is piped up to Ustream or wherever. There’s probably quite a few ways to do this, but my starting-point was The UStream Tool Kit — which also covers Windows.

Following Norwegian broadcaster NRK’s highly-successful trial of using BitTorrent for program distribution, the Canadian Broadcasting Corporation (CBC) has just released a prime-time episode of Canada’s Next Great Prime Minister onto the torrent globally.

According to the last100 report, the CBC’s media release was clear:

“The show will be completely free (and legal) for you to download, share & burn to your heart’s desire.”

In a follow-up post Inside story: the making of a legal TV ‘torrent’, freelance producer Interactive Producer for CBC Guinevere Orvis explains how they got the approvals sorted within the CBC.

On Thursday an email told me that I’m a beta tester for ABC Playback, the Australian Broadcasting Corporation’s Internet TV trial. So here we go…

I’ll gloss over the geeky stuff because the massively-brained Simon Rumble has already done a technical reconnaissance. Just three key points there from me:

1. It uses a Flash front end over XML program listings. Simon reckons it’ll be easy to hack up a Linux version for those who can’t use the official Windows and Mac interface. Or who want to avoid the pointless animations. Or who’d rather an easier-to-read high-contrast interface than trendy translucency.
2. A 30-minute program is compressed to a mere 130MB, which seems a reasonable compromise between quality and bandwidth — at least for infotainment — given the ABC’s need to serve regional audiences out on the Information Super-goat-track.
3. Did we really need to spend taxpayers’ money putting a clock in the top right of the screen? Computers already have clocks.

Technically it works just fine… but that’s not the real issue…

Disappointingly, ABC Playback seems more like the last gasp of old-style broadcast TV than a prelude to something new and wonderful.

While the music and movie companies rail against BitTorrent, Norwegian broadcaster NRK recently used the torrent’s capabilities to distribute a HD TV program to 80,000 people for just $350 total in storage and bandwidth.

[P]roject manager Eirik Solheim… estimated that the bandwidth bill would have been roughly $8000 had NRK chosen a more traditional delivery method…

All the HD video files were stored and delivered using Amazon’s S3 data service, which has optional bittorrent capabilities. NRK syndicated the .torrent episodes over an RSS feed, which allowed the program to work something like a podcast.

NRK recommends that people use Miro to subscribe: it’s the easiest way for folks to use BitTorrent and it fits their public-interest mission. The estimate that a high percentage of their downloaders (50% or more) are using Miro.

[...] Technically, the cost to the producer for distributing to a handful of viewers, say 300, is basically the same as doing so for 1,000,000 people. This is because after a point, distribution is handled by the viewers themselves; as the number of viewers rises, the work that NRK does stays constant.

I think I should be playing with Miro more…

Last night Channel Nine screened the crime drama Underbelly everywhere across Australia — except Victoria, where it was banned following a Supreme Court order. But thanks to the joys of BitTorrent, thousands of people have already downloaded it from the Internet. The law cannot cope in this new era.

As the screenshot shows, Underbelly was online within two hours of broadcast. By mid-morning today, 6500+ people had downloaded it from Mininova alone.

As with the Corey Delaney episode before it, this highlights the stupidity of the law in the bold new age of the Internet. I have no complaint with Justice Betty King’s decision. She’s just upholding the law as it stands. The law, alas, is hopelessly inadequate.

Who, I wonder, has this kind of law reform on their agenda. Anyone?
