No Programme Left Behind: Liberating
Television from the Tyranny of the Ephemeral Tom Loosemore Saturday 5th July 2008

The Small Print: Warning: this
speaker may give the impression of vague technical plausibility. This is erroneous. In truth, he’s one of those managerial bluffer types with ideas above his station. The last code he wrote was some catastrophically bad PHP back in 1999, leading an erstwhile colleague to revoke his access to CVS, stating ‘he knows just enough to be terribly dangerous’. Caveat Emptor .

Someone just broke TV

Bang to rights, Sir Tim…

How is TV broken?

99.9999% of TV is not
longer with us

And even the 0.00001% that
is available… can’t be found can’t be shared can’t be linked to

“ Make All TV Ever
Available, Findable & Addressable.” The Organising Problem:

Digital TV Digital Satellite DVB-S
Digital Cable DVB-C Digital Terrestrial DVB-T (aka Freeview) Digital Mobile DVB-H Digital Radio Digital Audio Broadcast DAB Digital Radio Mondial DRM Internet Broadcast Live Unicast streaming Multicast streaming (bbc.co.uk/multicast) Digital Broadcasting in the UK

Freeview: The UK’s best TV,
free.

Pros : Rich AV Content
Accessible Well structured Extremely Scalable Very High Availability Proven Cons Documentation Licence Ephemeral How does Freeview stack up as an API?

DVB-T Broadcast Audio & Video
API 2Mbs MPEG2 stream Widescreen Stereo View a single channel, or capture a multiplex Licence: Some programmes with CC licence DVB-T Broadcast Metadata API “Next 8 days” programme info Title, description, genre, channel, start time etc. UIDs & series linking not implemented. Licence: OK Freeview is really a pair of linked APIs

Damn. Ok, at least publish
the catalogue. open.bbc.co.uk/catalogue

“ Make All TV Ever
Available, Findable & Addressable.” OK. now back to that Organising Challenge:

Promise.tv : The last week’s
TV, in a box.

Is a Record-everything PVR possible?
Each Freeview channel is 2 Mbps MPEG2 Approx 2 GB per channel per hour 50 GB per channel per day 1 TB stores 4 channels for 7 days 3 TB stores nearly all good UK TV for 7 days But box would need 12 tuner cards… or would it?

OK, but…

“ Make All TV Ever
Available, Findable & Addressable.” Once again, that Organising Problem:

“ How about a year’s
worth of TV?” Real-time transcode MPEG2 to MPEG4 0.5 GB per channel per hour 12 GB per channel per day 1 TB stores a channel for 3 months 24 TB stores all BBC TV for a year Much too large to sit in living room 20,000 programmes - too many for ‘grid’ EPG… …and so to the Web!

BBCMacro.com: A year of BBC
TV

Of course, it did the
usual schedule stuff

But you could also search
20,000+ programmes

Download programme, Programme information,

Et voila: the collected works
of Cruickshank

User Ratings; User Comments

People + Programmes = Social
Scheduling

OK, but…

“ Make All TV Ever
Available, Findable & Addressable.” Back, for the final time, to that Organising Problem:

Need. More. Storage.

What if… ?

Some maths. Real-time transcode MPEG2
to MPEG4 An hour-long programme is 500MB 120TB stores all decent UK TV for a year So we need 10TB/month storage

Some more maths. Assume each
Impossibox had a 1TB disk Assume 100 bought each month That’s an additional 100TB storage each month But we only need 10TB each month 100 boxes/month = 10 copies of each programme And a very nicely seeded bittorrent cloud...

How the Impossibox Network Seeds

What Else Could It Do?
The ma’ and pa’ of all social TV navigation? Integration with DSL router? Popularity-based seeding? ISP-sensitive p2p? Targeted advertising? Encryption / PPV?
