No. ______ (Attorney Docket No. VWSI-27,509) filed Mar. 28, 2006 entitled “PORTABLE MEDIA ENCODER.” This application also claims the benefit of priority from U.S. Provisional Application No. 60/764,140 filed Jan. 31, 2006 entitled “PORTABLE MEDIA ENCODER SYSTEM” and from U.S. Provisional Application No. 60/782,497 filed Mar. 15, 2006 entitled “PORTABLE MEDIA ENCODER SYSTEM #2.”
  • TECHNICAL FIELD OF THE INVENTION
  • [0002]
    The present invention relates to streaming audio/video media, and more particularly to portable devices for providing streaming media over the Internet or a private network.
  • BACKGROUND OF THE INVENTION
  • [0003]
    As the use of the Internet has become ubiquitous, more services are being offered online. This includes not only interactive services for which the Internet is widely known, such as email, online shopping, online banking, and customized information services, but has also come to include services that have traditionally been non-interactive, such as the provision of radio programming and television programming. Streaming media, in primitive forms, has been present on the Internet for some time. However, as greater numbers of users gain access to high speed data lines through school, through work, or through a home based broadband solution, more people will come to see the Internet in general, and streaming media in particular, as a viable alternative for the delivery of media content. This includes daily programming such as typically appears on network broadcasting stations as well as special event programming such as movies and sporting events.
  • [0004]
    Streaming media delivery is both promising and problematic. With traditional media delivery vehicles such as broadcasting and cable or satellite feeds, users typically must plan to be available when the broadcast is available or make other arrangements on their own. However with streaming media and Internet content, users expect delivery to be at their discretion. This can raise a variety of issues for providers as they attempt to deal with what is essentially replicating the broadcast event for every viewer. In addition to current and ongoing programming, providers are faced with the problem of legacy programming that may prove valuable if it can be provided more or less on-demand when viewers so request. The vast amount of programming currently available, as well as the large volume of non-digital legacy programming, can create problems associated with the scale or size of a given operation as well as with the technical difficulties involved in the delivery.
  • [0005]
    In addition to digitally encoding legacy programming, economies may be gained by providing a real-time digital stream corresponding to a filmed or taped event as the event is occurring. In this way, an event need not be filmed or recorded in a traditional manner and then converted to an appropriate digital format. Live coverage of an event could be provided directly in a streaming digital format. The event would be “broadcast” over a packet-based network. For some events, it may be possible to skip the traditional filming entirely and simply provide coverage in a digital streaming format. Of course, the digital stream could also be archived for later viewing or retrieval. The digital streaming broadcast model may also appeal to those without sufficient capital to invest in traditional recording or broadcasting equipment. Home videos, for example, could be captured and streamed directly over the Internet.
  • [0006]
    Therefore what is needed is a system and method for dealing with the issues discussed above and related issues.
  • [0007]
    It is also desirable to facilitate the use of streaming media encoders in a variety of conditions. In some circumstances, e.g., when the encoder is stationary, the use of wired microphones, wired internet connections and/or grid power may be acceptable, whereas in other circumstances, e.g., when the encoder is mobile, the use of wireless microphones, wireless internet connections and/or battery power is preferable. Permanently mounting and connecting the accessory devices necessary to provide such wireless or battery capabilities to a portable media encoder may result in increased weight and complexity that is not always required. Further, it is desirable to have the ability to quickly change between different suites of accessory devices without individually mounting and connecting them.
  • [0008]
    A need therefore exists, for a quick-connect accessory mount that facilitates quickly mounting and connecting accessory devices to a portable media encoder without individually mounting and connecting them, and vice-versa.
