TiVo complains to FCC about SDV use
TiVo Inc. has reached out to the Federal Communications Commission (FCC) over concerns that the use of Switched Digital Video (SDV) technology by Cable providers will destroy its business. While traditional cable infrastructure delivers all available channels at once to subscribers' receivers, SDV will deliver only the channels currently being accessed.
The benefits of SDV are obvious; savings in bandwidth for one and the possibility of setting up systems with multiple times the channels currently being offered to subscribers. The system requires a receiver to send an upstream signal to a cable headend to request a signal be sent down the cable; a TiVo box cannot do this and relies on infrastructure that allows it to simply lock on to the available signals.
In a nutshell, this means that a TiVo box cannot change a channel on a SDV-based system, whereas a provider-issued box can. TiVo attacks the industry in a filing with the FCC on the issue, pointing out that TiVo is the "only major competitive entrant left standing" in the DVR space. It attributes this position to Cable's historical reluctance to open networks to third-party hardware, as opposed to natural free-market forces.

Twitter has boasted that its users now send out 50 million 140-character-or-less tweets per day, or about six hundred per second. The micro-blogging giant, which is usually mute about much of its statistics, revealed the milestone on Monday. The site had five thousand tweets every day back in 2007, which went up to 300,000 per day in 2008.
