  • 10. Patriot Media Forum Specific Info

    ·Does Patriot Media officially offer support via the forum?
    ·Who moderates the Patriot and RCN forums?
    (back)
    Unfortunately, it appears Patriot no longer maintains a full-time presence on this board. WorkinClsDog See Profile (who created this FAQ) is no longer a Patriot Media employee and does not monitor the forum any longer.

    As a result, the best method to assure that you receive the most timely response to your issue is to contact Patriot's 24-hour customer service center at their 24 hour toll free number 1-866-PAT-1776

    You can post your questions and comments here for feedback from your fellow Patriot customers, and even suggestions for assistance. Occaisionally, some Patriot tech support staff have posted in recent months - but not on a regular basis.

    As a result, the best approach is to contact Patriot's customer service center directly.

    ·What is DOCSIS?
    ·What is CableCard?
    ·What is HDMI?
    ·What is DVI?
    ·Can I connect from HDMI to DVI?
    (back)
    DOCSIS (Data Over Cable Service Interface Specification) is the Cable Modem standard that defines the interface requirements of high-speed data transmission over cable networks. Patriot Media's network requires your modem to be DOCSIS 1.1 compliant.

    A CableCARD is a device that consumers who own Digital Cable Ready (DCR) TVs will receive from their Cable provider to allow for the descrambling of digital programming. The card is inserted into your DCR TV and allows for the descrambling of the digital signal. The card works in place of a traditional set top box.

    Cablecard will not allow a subscriber to receive TV Guide services, Pay Per View, or Video on Demand due to the one-way nature of the CableCARD device's function.

    What is HDMI? (#11243)

    (back)
    HDMI (High Definition Multimedia Interface) is a specification that combines video and audio into a single digital interface for use with digital versatile disc (DVD) players, digital television (DTV) players, set-top boxes, and other audiovisual devices. The basis for HDMI is High Bandwidth Digital Content Protection (HDCP) and the core technology of Digital Visual Interface (DVI). HDCP is an Intel specification used to protect digital content transmitted and received by DVI-compliant displays.

    HDMI supports standard, enhanced, or high-definition video plus standard to multi-channel surround-sound audio. HDMI benefits include uncompressed digital video, a bandwidth of up to 5 gigabytes per second, one connector instead of several cables and connectors, and communication between the video source and the DTV. HDMI development is overseen by the HDMI Working Group that includes Sony, Hitachi, Silicon Image, Philips, and Toshiba as members.

    HDMI will replace DVI eventually for Home Theater connectivity. Point to point interface - connects only two devices at a time.

    What is DVI? (#11244)

    (back)
    DVI refers to a type of Digital Video connection. This method is a high quality connection for HDTV's and Set Top Boxes/Receivers that support it.

    Video is compatible with HDMI provided both devices are HDCP compatible. DVI carries uncompressed video data, but no audio. Point to point interface - connects only two devices at a time.

    This type of connection is used on some HDTV's, Projectors, Set Top Boxes and Receivers. DVI cables are usually only available in limited length. DVI will be replaced by HDMI for Home Theater applications.

    Yes. However, you will only have the video functionality however. The video portions of HDMI and DVI are compatible. You can use an HDMI to DVI cable or a HDMI to DVI Adapter.

    Whether or not it will actually work or not requires a bit more complex of an answer due to HDCP. It is meant to prevent viewers from copying content they are not "allowed" to copy. (see definition of HDCP in this FAQ)

    HDMI connectors all use HDCP. DVI connections on the other hand, may or may not have HDCP. Computers and LCD monitors for example, can have DVI connections which do not have, or "need" HDCP. Many of the early HDTV's to include DVI connectors do not have HDCP. Some projectors, especially non-Home Theater oriented ones with DVI connectors do not have HDCP. Generally you will need to be sure that both devices use HDCP in order to connect together an HDMI device and a DVI device.
