Simultaneous charging is one of MHL’s advantages over Slimport and Miracast. MHL Consortium The Mobile High-Definition Link (MHL) standard already lets you connect certain phones, tablets, and other devices to your TV using adapters that connect to the devices’ micro-USB ports. But the consortium has just announced that an upgrade is coming: the new MHL 3.0 standard adds support for 4K displays. This will allow mobile devices that support the standard to output 3840×2160 (also known as 2160p) video at up to 30 frames per second, an upgrade from MHL 2.0’s 1080p. The updated standard can transmit data and video simultaneously, and a device connected via MHL can draw up to 10 watts of power to charge your device. Backward compatibility with MHL versions 1.x and 2.x, HDCP 2.2 DRM support, and 7.1 channel surround sound support are also part of the standard. The MHL standard competes with a few standards (as well as Apple’s proprietary AirPlay), all of which are designed to put your phone or tablet’s display up on your TV. There’s SlimPort (used most prominently in Google’s Nexus 4 and 2013 Nexus 7), a DisplayPort-compatible spec which like MHL uses the micro USB port to connect over HDMI. There’s also Miracast, an Airplay-like standard that uses a Wi-Fi-equipped receiver to beam video to your TV without the use of cables (Miracast support was baked into Android beginning in version 4.2 , but it’s also included in a smattering of other devices). Neither standard supports 4K video at this point, making MHL 3.0 slightly more appealing for those on the bleeding edge of TV technology. Read 1 remaining paragraphs | Comments

On Tuesday, the American mobile phone market took one step closer to looking a bit more like the European or Asian markets: free incoming calls, inexpensive outgoing calls, and a focus on data. A Canadian startup, TextNow , just launched a new mobile service in the United States. For $18.99 per month, you get 500MB of data, 750 rollover minutes, and unlimited texting and incoming calls. In the US, it’s the norm for both the sending and receiving parties to be charged for a call. But nearly everywhere else in the world, only the person who originated the call actually pays. “Incoming calls don’t really cost us that much, ” Derek Ting, the company’s CEO, told Ars. “Carriers charge you anyway because they can get away with it.” Read 5 remaining paragraphs | Comments
The University of California—an enormous institution that encompasses 10 campuses and over 8, 000 faculty members— introduced an Open Access Policy late last week. This policy grants the UC a license to its faculty’s work by default, and requires them to provide the UC with copy of their peer-reviewed papers on the paper’s publication date. The UC then posts the paper online to eScholarship , its open access publishing site, where the paper will be available to anyone, free of charge. Making the open access license automatic for its faculty leverages the power of the institution—which publishes over 40, 000 scholarly papers a year—against the power of publishers who would otherwise lock content behind a paywall. “It is much harder for individuals to negotiate these rights on an individual basis than to assert them collectively, ” writes the UC. “By making a blanket policy, individual faculty benefit from membership in the policy-making group, without suffering negative consequences. Faculty retain both the individual right to determine the fate of their work, and the benefit of making a collective commitment to open access.” Faculty members will be allowed to opt out of the scheme if necessary—if they have a prior contract with a journal, for example. Academic papers published in traditional journals before the enactment of this policy will not be made available on eScholarship at this time. Read 3 remaining paragraphs | Comments
On Saturday, the Obama Administration vetoed the International Trade Commission’s potential ban on a few models of older Apple phones and tablets. Samsung opened the case against Apple with the ITC in 2011, and the commission decided in June that Apple had, in fact, infringed upon a Samsung patent, US Patent No 7, 706, 348 . The decision garnered attention because the patent is considered essential to industry standards, meaning Samsung is required to license the patent (rather than sit on it, or refuse license it to some competitors). The ITC ended up recommending a ban be placed on the infringing products brought forward in the case, which included AT&T models of the iPhone 4, the iPhone 3GS, iPhone 3, iPad 3G, and iPad 2 3G. In June of 2013, Ars wrote of the ITC’s ban: ”The decision can only be appealed to the US Court of Appeals for the Federal Circuit, the nation’s top patent court. Theoretically, the President can also block an ITC-ordered import ban, but that hasn’t happened since the 1980s.” Read 4 remaining paragraphs | Comments
