MYDP for watching the smartphone and tablet content on TV

With the growing trend of people using either smartphone or tablet computer for surfing net and also to read the e-content, the need of seamlessly interfacing them to bigger displays is also growing. If a wide and a big screen TV or LCD monitor is nearby it makes sense for the user to see content of smartphone or tablet on such big screen. To do this there is no technological barrier, the only barrier is available of right standards for interfacing audio and video from tablet and smartphone to big screen displays.

ST Microelectronics has come out with new standard called 'Mobility DisplayPort (MYDP)' to address this requirement, which enables piping of High-Definition audio and video between smart mobile devices and TVs.

MYDP is 100% compatible with the DisplayPort digital-protocol standard and enables 1080p/60Hz audio and video (A/V) streaming between smart mobile devices and full-high-definition (1080p) TVs and monitors via the standard connector found in the majority of mobile consumer products such as tablets, smart phones and portable gaming consoles. The MYDP standard also offers concurrent A/V streaming and battery charging of the mobile device via the same standard connector.

STMicroelectronics said it has submitted the proposal for the new MYDP interface standard to VESA (Video Electronics Standards Association) with the aim for it to become the defacto standard for A/V output from all portable electronic devices.
Some of the points highlighted by ST on this wired interface are:

1. DisplayPort is expected to become a major high-definition video interface in the coming years, following the recent declaration of several major consumer electronics manufacturers and computer makers to drop support for the VGA/DVI standard by 2015.

2. Unlike DisplayPort, however, MYDP is designed specifically for mobile devices and equipment, where space is extremely limited. It demands the use of only one connector for data exchange, audio/video output and connecting to other A/V accessories.
3. MYDP therefore maintains the minimum 'connection footprint' of the mobile device, removing the need for additional connectors and thereby reducing bill-of-materials costs to deliver uncompressed high-definition video (up to 1080p/60Hz) and audio (up to 7.1 channels at 192,000 samples per second) for direct connection to either a TV or audio system.

4. The MYDP standard is designed to work via any connectors currently used in mobile applications. In addition to the DisplayPort standard functionality, MYDP also brings the capability to charge the mobile handset from the connected TV or monitor. MYDP takes full advantage of the scalability of DisplayPort and maps audio and video streams on to one differential pair (or lane). A sideband channel signal, AUX_HPD, carries the sideband channel signals of the DisplayPort standard, namely the AUX CH differential pair (AUX CH+ and AUX CH-) and HPD over a single pin.
