  • Scan ATSC Preparing the Scan

    Scan ATSC Preparing the Scan

    Scan ATSC Preparing the Scan You should see one or more tuners listed as type Atsc. Tip If you don't see any tuners listed this indicates TV Server has not yet successfully detected your tuners. Close TV Server configuration, wait 30 seconds, then reopen. Note that you may see more tuners than you expect for three reasons: Silicondust created a "wrapper" for their HDHomeRun PRIME CableCARD tuners that allows software like MediaPortal to use them for clear QAM only. Tuners named like HDHomeRun Prime Tuner are capable of receiving encrypted cable channels; tuners named like Silicondust HDHomeRun Tuner are physically the same tuners but are only capable of clear QAM. If you have a CableCARD, we recommend you disable (untick) the clear QAM wrapper tuners to avoid confusion. On 32 bit versions of Windows 7 or newer you may see each CableCARD tuner listed twice. This is because MediaPortal supports two ways of controlling the tuner hardware. Tuners with device path starting "@device:sw..." use the Windows PBDA control interface. This is the interface used by Windows Media Center. Tuners with device path starting "uuid:" use the CableLabs native UPnP/DRI interface. This is the interface used by most other software. Only one interface should be used to control each tuner. The PBDA interface may be more reliable but will certainly be significantly slower than the native interface. We recommended that you disable (untick) the PBDA tuners unless troubleshooting. If your tuner supports both digital and analog sources (a so-called hybrid tuner), expect to see one tuner of type Atsc for receiving from digital sources and one tuner of type Analog for receiving from analog sources.

Having a reliable EPG makes your TV experience more like a commercial set top box (e.g. Sky Digibox). There are many different ways to populate your EPG (via internet data and data received by your TV tuner).The best method depends on your TV Card. region, Service Provider and the quality of data available. This guide presents the main methods plus several different Setup tutorials, with examples for specific regions/countries: DVB if you have a DVB TV Card and your TV broadcaster includes good EPG data this is the easiest method to use: DVB EPG Data However, often DVB sources provide data only for the next 48 hours, which is not very useful for scheduling recordings. XMLTV XMLTV is an XML based file format for describing TV listings. There are a number of software tools that you can use to download your EPG data and import it into MediaPortal using the included XmlTV plugin - see TV Guide > EPG > XMLTV for some of the more popular tools.

    Media Center Oriented Linux Operating System

    Media Center oriented Linux Operating System Tudor MIU, Olivia STANESCU, Ana CONSTANTIN, Sorin LACRIŢEANU, Roxana GRIGORE, Domnina BURCA, Tudor CONSTANTINESCU, Alexandru RADOVICI University “Politehnica” of Bucharest Faculty of Engineering in Foreign Languages [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], , [email protected] Abstract: Nowadays there is a high demand of computer controller multimedia home systems. A great variety of computer software media center systems is available on the market, software which transforms an ordinary computer into a home media system. This means it adds some functionality to the normal computer. Our goal is to develop such a user-friendly intuitive system, dedicated for home media centers. In contrast with other proprietary approaches (Windows Media Center, Apple TV), we are building an entire operating system specialized on this. It is based on the Linux kernel, thus providing high portability and flexibility at a very low cost. The system is designed to work out of the box (plug it in and use it), needing zero configurations (no human configuration as much as possible) and no installation (Linux-live system, works from a CD, DVD or USB device). The user interface is not more complicated than a generic TV user interface. In this aim, the file system is hidden from the user, being replaced with an intuitive media library, the driver configurations is done automatically, network configuration is also handled without user actions (as much as possible). Key-words: OS, media center, Linux, multimedia, portable, intuitive, free, open-source 1.
