  • Broadcasters Sue To Stop $12 Streaming Service Aereo
  • Broadcasters don't like "tiny antennas," sue TV streaming startup
  • Actually 2 lawsuits
  • Aereo Responds To Broadcasters’ Lawsuit: Your Position Does Not Have “Any Merit”
  • Broadcasters Sue New York ‘TV Anywhere’ Startup Aereo
    • You knew this was coming - Aereo just got itself sued twice for copyright violations
    • The Lawsuits:
      • The first suit, filed by ABC, CBS and NBC, among others, states that “Aereo has no rights, under any license, statute or case law, to any of the copyrighted programming that is the basis of its subscription only internet service.” Aereo is not paying to rebroadcast --> infringement
    • Second: case against Aereo was filed by PBS, Fox Television Stations, Univision Television Group, the Univision Network, Twentieth Century Fox Film Corp., WNET and Thirteen. This case seeks to block the Aereo service, damages, as well as any lawyer or court fees." **Aereo responded publicly: "Aereo does not believe that the broadcasters’ position has any merit and it very much looks forward to a full and fair airing of the issues."
    • "Aereo provides technology that enables consumers to use their cloud DVR and their remote antenna to record and watch the broadcast television signal to which they are entitled anywhere they are, whether on a phone, a tablet, a television or a laptop."
    • ArsTechnica talked to James Grimmelmann, a copyright scholar at New York Law School who thought that Aereo has a "non-laughable case" and compared the situation to the Cablevision remote DVR case where the case hinged on whether Cablevision stored individual recordings for each customer (they did, so they won).
    • Quick background: Aereo uses tiny OTA antennas combined with cloud DVR. 1 to 1, req's NYC billing and IP address

News Fuse





"Hi TNT crew You talked about mobile networks with unlimited data plans and trafic congestion in episode 448. I live in Finland where unlimited data plans are the norm with mobile data customers. People either don't use a phone for data at all or they have an unlimited data plan.You could get a metered megabyte plan, but it is horribly expensive compared to unlimited plans. The thing is, that unlimited here means data amount. Plans have an unlimited data amount, but you pay different for speeds. There are cheap plans, which limit speed to around 512 kb/s. This costs around 5€/month. Unthrottled high speed LTE connection costs around 40 €/month.

I think this is better way to price plans, than metering data and selling everyone full speed connection. Many people will use phone for email, using social networks, IM and checking news sites, so speed is not critical for this customer group. On the other hand there are people who want to use it for high speed critical services like video streaming. If you try to sell full speed to everyone, you are selling an overkill to the people just wanting to check email and you lose potential customers, who can't afford expensive highspeed connection, but would want to have some kind of mobile internet connection.

if you are willing to dish out the cash, you can get totally unlimited in every possible way connection. It just won't be cheap.

Ari from Finland"

"Tom, Sarah, Iyaz, Darren, Jason, and crew,

Thursday you requested some engineer speak on mobile spectrum as related to data charges. I posted some recent links on this issue to the TWIT wiki back in December, which could help:

At 15:12 of my linked audio recording I discuss spectral efficiency correlated to capacity theorem. So you can infer, as much as I'd love for phone companies to be entirely BS'ing with upping data rates, it is a real concern. Likely not nearly as much of a concern as they're charging us for! And certainly not nearly enough of a concern for app, OS, and hardware developers!

"hey all,

Seeing all the discussion over how new high end phones seem to be getting bigger and bigger, I thought i'd shed some more light on why.

The screen size is generally not a design goal as a result of consumer response, it is a symptom/side effect of other design issues. What I mean is that new high end SOC's and tech like LTE are not only battery hogs, they take up more physical space. This means that more room is needed to fit everything in, and add in the need for bigger batteries and a desire for thin devices, the only solution is a larger footprint and thus: bigger screens.

So we should expect future devices that use current tech to get smaller, but the bleeding edge will remain oversized, for good or ill.
