Thinking about it - TV for tomorrow

I just spent a few minutes thinking about tomorrow's TV. I am more and more convinced that Apple is going the right way, but to complete its offering they need some additional stuff:

Have now



- Apple TV (WiFi to HDMI, internet access limited to iTunes and few other media sources)
- Computers WiFI (iMac, MacBook)
- NAS and routers WiFi (Time Machine)
- Remotes WiFi (iPod, iPad, iPhone)

Eco-system.png

Needed to complete the picture



- Set-top-box receiver with WiFi interface for streaming TV and for remote control. View on TV, record on MacBook/iPad/iPod/iPhone...
- Expanded internet access (directly by ATV or WiFi stream from iPod/iPad/iPhone)
- WiFi sync computer to iPad/iPod/iPhone
- Audio amplifier (optical in, LS out) for HiFi system

This would give the perfect solution. With just ONE remote, an iPod, iPad or iPhone). Everything WiFi.

Opportunity



There is a big opportunity here for someone (EyeTV?) to make the STB and someone making HiFi amplifiers to come up with the missing hardware (who?), the HiFi part of the needs could be satisfied using active (Optical Audio input) loudspeakers (ADM?)

Grabing your TV

A quick first comment, more later...

There is a definite acceleration in the mish-mash of offerings for your eyeballs. Your TV set is about to be an internet thingy, a video-on-demand thingy, a catchup TV thingy, a gameing thingy. Offerings are coming from many new makers, of which Apple, Goggle and UK's YouView are just some of the media ones.

Apple TV - your TV as a monitor



The new Apple TV is an amazingly small and simple box. It links to the world via WiFi and to your TV by HDMI, and that's it. But what it does is put your TV into the Apple eco-system. You can browse the iTunes store and rent movies and TV programs, you can stream movies from your other Apple gear - your MacBook, your iPad, your iPhone... - directly to your TV screen. And all in 720 HD format.

Apple TV also streams audio to its Optical audio output, connect your ADM9.1 powered loudspeakers and you have a complete music centre, also based on buying music from iTunes. And playing from your iPad remotely.

But the Apple TV does not have the BBC's iPlayer. For some reason these two guys cannot get on enough to allow the BBC to create an iPlayer app (probably the DRM problem, Apple won't licence there's and the BBC can't implement iPlayer without DRM as the studios won't have it?).

The Apple TV also does not have TV!

And you have the frustrating business of using the TV remote to switch across to Freesat, another to watch a DVD or Blu-Ray, another to control your HiFi... More than one controller for your home system is too much.

Google TV - your TV as a nerd's paradise



Google TV is just an OEM software product, like their new Android OS. It is provided to equipment and TV makers to implement. When included it allows the TV to become a TV, a VOD source, and an internet browser (for YouTube, etc).

Google TV uses a QWERTY keyboard so you get the full computer/internet experience on your TV, much to the annoyance of everyone else in the room... A TV is a shared experience, not the domain of one person holding the remote.

There will also be Google TV boxes that link up to older TVs.

Google is working hard, at least in the USA (there is no sign of Google TV support in Europe) to get a lot of media sources signed up - the likes of Netflix, Hulu, and the TV channels.

YouView - your TV as a broadcaster's delivery terminal, but via the internet



YouView is the broadcasters idea of what the future of TV should be like. When they think they have to move from expensive TV transmitters, expensive Satellites and onto the internet as a delivery chain, YouView is what they have come up with. But it is a closed, gatekeeper system, not the open internet.

There's not a lot going for YouView, it has no eco-system, it is just another set top box you have to buy (after you have already purchased one or two generations of Freeview and Freesat boxes), great for the licensed electronic's companies, but very bad for the consumer.

What is worse is that the whole thing is to be dominated by the BBC who will control the User Interface - look and feel. Its a total lock-in.

Don't forget



Apple and Google are building huge data centres - to store movies, music, TV shows? They plan to be the complete offering, storage and delivery. Maybe the broadcasters don't stand a chance in this battle.

What could you imagine?



You don't want just a TV, you don't want internet on your TV - a TV is a shared viewing experience, not a individual one. You don't want multiple boxes, plus your DVD and Blu-Ray players, Wii and others connected by a forest of wires and half a dozen different remotes.

What you want is an eco-system that integrates your PC, your Pad, your Phone, your game box and your TV. In such as way that they can all be used separately, or can interact to give your eyeballs all the information they need, when they want it.

Who will win the battle? Well it depends how stupid we are.



YouView may be foisted on us, by politicians who don't know any better or care, and by the powerful media giants (BBC, ITV, Five, Arquiva (who run the TV transmitters), BT (who own the telephone lines and exchanges) and others). But it is probably not what we want or need.

Apple may like us to invest in their eco-system, and they have been pretty successful in doing that! But they don't have the media offering we need - no live TV, no catch up (maybe coming?), so far few rentals, no purchases. But they do have interconnectivity which others don't.

Google TV is a loser, like many of the other Google ventures. It depends on getting us to buy complete new TVs. It offers combined TV and internet, which means it reaches only one set of eyeballs, not a shared experience. Sure it is an interesting distribution channel, but so are the others.

My money is on Apple in the end, the TV as a monitor, it makes system sense. But they desperately need to have a long hard look at the UK market and give us the features we want.

The other battle - copyright sub-division and control



Of course the other battle is between the companies that deliver the media (Apple, Google, Netflix, Hulu, Seesaw, Cable, Sky, BT, Virgin...) and those that generate it. For too long studios have been controlling the delivery chain, licensing sub-divided permissions of copyright to others who want to carry the content. Even our public broadcaster, the BBC, has fallen in the trap of believing it needs to own the delivery chain and play the studio's game (viz DRM on the "free" iPlayer catchup service, and limits to the time programs are available...). Sorry but public broadcasting is just that, public. It has also chosen a strong encryption system (or DRM) for the YouView project. Our TV is now firmly locked up.

Rogue thought



I watch 1500 hours of TV a year, I pay £140 TV licence for this. Or about £0.10 per hour of viewing.

If I just paid £0.10 per view, and no licence fee. And had free and open access to all channels, VOD on the internet would this be better? Yes, Yes, Yes.

But then YouView has no payment mechanism, so this blocks even this outrageous suggestion.

Paper chase "PoP" - in the digital world

I have seen thousands of people in offices walking around carrying a piece of paper that they take to someone else and waste time having a chat...

In the world of WiFi networks, cloud storage and iPads there is a better solution. I propose this "app" and solution:

- Documents are created on the iPad or scanned, word processed and loaded by WiFi, probably the best is to have them all in PDF format with embedded metadata (Author, Subject, Key Words etc) and an urgent/normal, read/unread tag.
- A database of users is kept on a server, and this is synched to all iPads in the network automatically
- Any user can take a document they have created, chose another user and "PoP" it across to them. Or they can chose a group of users and "PoP" it to all of them
- Any user will see their received documents, tagged as urgent/normal and read/unread
- Document filing will happen in the cloud. This is the tricky bit as few people have solved the problem of decently classifying documents and providing access by other than searching. So search will be important. Only one copy of any document need be kept with metadata about who "PoP"ed it and who received it (and maybe who read it!)

Add-on. Classification

Any classification system needs a central control or defined "menu" so avoid random tagging. Such a menu structure could be defined by a system administrator and imposed on the cloud document database.







Apple TV needs digital amplifier

Have a look at the new Apple TV, a wonderful small device that has LAN input (Ethernet or WiFi) and HDMI and Optical Digital Audio output, and you will see a connectivity need.

Sure you have the simplicity to connect your flat screen TV with its HDMI input direct to the Apple TV and get HD video and audio. But if you want to be a HiFi buff and connect your giant loudspeakers to the Apple TV you need an amplifier with Optical input. These do exists but are expensive.

So what I propose as a new product is a medium cost, high spec audio amplifier to fill this niche:

- Tower design matching the same width and depth as the Apple TV
- Optical TOSLINK input at up to 24bit/96kHz (its not clear if the Apple TV will stream 24bit/96kHz but it may in the future, for now iTunes probably down-samples everything to 16/44.1
- Balanced audio analog input
- Superior DAC based on the world leading Wolfson chips
- Two class D audio amplifiers, possibly the Hypex modules, giving > 100W per channel.

As an alternative solution a completely digital amplifier could be built using a digital audio receiver (e.g. STA120, WM8804...) plus an integrated digital amplifier like the STA328, giving 40-60W per channel.

Contact me if you have any interest to commercialise these ideas.

Better Music

I agree with Bob Speers:

"What happened to dynamic range? That's a question that should be asked of record labels, producers, artists, and last but not least, recording and mastering engineers. The question needs to be asked because we're the ones responsible for what's happened to our music. Much of the music we listen to today is nothing more than distortion with a beat. Great music is suffering because it lacks dynamic range. When music lacks dynamic range, it lacks punch, emotion, and clarity. The record labels blame digital downloads, MP3s, CD burners, and others for the lack of CD sales. While there is some truth to their constant whining, they only have themselves to blame for the steady decline in CD sales. The record labels need to reevaluate what they consider to be good music."

I have been blogging for years about the need for the record companies to recognise that the way forward is better technology. Now we have wider bandwidths for our broadband connections, we can download tracks in FLAC or ALAC non-lossy formats. The biggest music distributor, Apple iTunes, needs to recognise this also and push the record companies to provide studio master recordings without all the limiting and compression that is used on CDs, AACs and MP3s.

Let's see this in technical terms (from Wikipedia):

Screen shot 2010-09-09 at 12.22.39.png

This dramatically shows the limitations of the 16bit CD and FM radio, and the improvements we could have by using 24bit downloads. I don't have any figures for MP3 or internet streaming but they will be much worse.

A properly recorded CD at 16bit resolution, should have its 0dB level equivalent to a digital level of -18dBFS, giving an 18dB overhead, a 24bit file should have the 0dB analog level (1.23V rms) set to a digital level of -24dBFS thus giving a 24dB overhead before digital clipping occurs. For comparison live music demands an overhead of 30dB.

Canvas vs new Apple TV

Who needs Canvas now we have the new Apple TV. Way to go Apple!

Apple has defined the technology for rental/streaming TV. They have built it into a box that anyone would be happy to have in the living room (its just 4inches square!). It is simple, just WiFI/Ethernet connection and HDMI to your TV/monitor. (By the way who needs a TV anymore, you just need an HDMI input monitor with sound built-in).

So why not drop Canvas, which is an overcomplicated system, just like the European proposals, integrating web and TV? What users want is simple, they want content, not interactivity.

The BBC and others must go back to making programs, and stop all this technology "innovation" nonsense. They don't seem to get it.

I look forward to BBC TV on my Apple TV box.

Forget 30 pins - use USB Apple

It really is time that Apple stopped using that clumsy 30 pin dock connector on their products - iPhone, iPod touch, iPod Nano...

Screen shot 2010-09-03 at 08.41.41.png

The future is USB and WiFi. USB for communications and power/charging and WiFi for sync and up/down loading plus internet/LAN connections.

If Apple don't quickly move in this direction they will have lost important ground. They have already shown they can do it by the new AirPlay that streams audio and video between devices, especially to the new Apple Tv.

So go to it Apple, update.
