No Programme Left Behind:Liberating Television from the Tyranny of the Ephemeral

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…
9
How is TV broken?
10
99.9999% of TV is not longer with us
11
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:

Freeview: The UK’s best TV, free.

Pros:Rich AV Content Accessible Well structuredExtremely ScalableVery High AvailabilityProven
Cons Documentation

How does Freeview stack up as an API?
16
DVB-T Broadcast Audio & Video API
2Mbs MPEG2 streamWidescreenStereoView a single channel, or capture a multiplexLicence: Some programmes with CC licence
DVB-T Broadcast Metadata API
“Next 8 days” programme infoTitle, description, genre, channel, start time etc.UIDs & series linking not implemented.Licence: OK
Freeview is really a pair of linked APIs

Once again, that Organising Problem:
27
“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 day1 TB stores a channel for 3 months24 TB stores all BBC TV for a year
Much too large to sit in living room20,000 programmes - too many for ‘grid’ EPG…
…and so to the Web!

Back, for the final time, to that Organising Problem:
39
Need. More. Storage.
40
What if… ?
41
Some maths.
Real-time transcode MPEG2 to MPEG4 An hour-long programme is 500MB120TB stores all decent UK TV for a year
So we need 10TB/month storage
42
Some more maths.
Assume each Impossibox had a 1TB diskAssume 100 bought each monthThat’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...
