  • Publication number: 20120198335
    Abstract: An apparatus and a method for automatic real-time cloud computing processing of live multimedia content are disclosed. In one embodiment of the invention, a portable electronic device can transmit live event multimedia data to a web/cloud computing storage service in real time, wherein the web/cloud computing storage service segmentizes incoming streams of the live event multimedia data into multiple media files during an ongoing transmission of the live event multimedia data. In one embodiment of the invention, the size of each segmented media file depends on a current network traffic condition and/or a bandwidth availability. By automatically segmentizing the streams of encoded multimedia data into individually-viewable segments for the web or cloud-computing storage service, a user can start viewing the currently-uploading multimedia data faster than a conventional single stream upload which requires a longer waiting time.

  • Patent number: 7984179
    Abstract: Methods and systems for transmitting compressed audio/video data streams across conventional networks or channels in real time. Each system employs the Adaptive Rate Control (ARC) technique that is based on the detection of defective packets and other influencing factors such as overall system performance, usage model and channel characteristics. To control data stream congestions in the channel and maintain the visual display quality above a certain level, the present invention exploits the human visual perception and adaptability to changing visual conditions. The ARC technique relies on the client's capacity for calculating the quality of video packets received from a server and sending information of a desired transmission rate to the server. This approach simplifies the hardware and software implementation complexity otherwise imposed on the server and reduces the overall design cost by shifting the burden of monitoring bandwidth and transmission control from the server to the client.

  • Patent number: 7917615
    Abstract: A method and an apparatus for real-time monitoring and controlling of networked appliances over both a wide-area network (WAN) and a local-area network (LAN) using a Device State and Location Server (DSLS) as an intermediate server are disclosed. The DSLS is configured to either receive beacons from networked appliances periodically or poll networked appliances to update current activity status of each networked appliance. A unified user interface on a commanding device is configured to monitor the current activity status of each networked appliance by simply receiving updated data from the DSLS, thereby offloading a cumbersome task of tracking all networked appliances over the WAN and the LAN on its own. A color coding scheme and different icon shapes are used for ease of monitoring of the networked appliances. An orbital user interface software further helps to visualize location and current activity status of each networked appliance.

  • Publication number: 20110061086
    Abstract: An apparatus and a method for multimedia data handling to a web or cloud-computing service are disclosed. A set-top box can generate a pre-encoded stream of digitized data after receiving a raw incoming multimedia signal or after receiving a pre-processed, decoded, decompressed, and/or decrypted incoming multimedia signal from a service provider-specific signal receiver. The set-top box can also generate streams of encoded multimedia data from the pre-encoded stream of digitized data and segmentize the streams of encoded multimedia data into individually-viewable segments for uploading to the web or cloud-computing service, wherein a size of each segment varies based on a current connection bandwidth availability and/or a workload on the set-top box. By automatically segmentizing the streams of encoded multimedia data into individually-viewable segments for the web or cloud-computing service, a user can start viewing the currently-uploading multimedia data faster than a conventional single stream upload.

  • Publication number: 20100287312
    Abstract: An apparatus and a method for intelligent analysis of device compatibility and adaptive processing of multimedia data are disclosed. By performing a unique intelligent analysis of device compatibility, the present invention provides a full application-level compatibility between the apparatus performing the intelligent analysis and an external device operatively connected to the apparatus even when device driver-level information of the external device is unavailable. Furthermore, a unique intelligent analysis for adaptive processing of multimedia data between the apparatus and the external devices enables an efficient and flexible usage of storage space in the external device for a multimedia data transfer from the apparatus to the external device.

  • Publication number: 20100162335
    Abstract: An apparatus and a method for controlling a network-connected device in one peer network from an infrared (IR) device connected to another peer network is disclosed. Regardless of underlying communication protocols used in peer networks, the IR device in a peer network can request a transfer of data or control to a networked device in another peer network. Communication compatibility among the two peer networks are maintained by utilizing a set-top box in each peer network configured to communicate with another set-top box using a transport control protocol (TCP), which may be different from underlying protocols (e.g. X.25, IrDA) between the set-top box and locally connected devices to the set-top box. The set-top box may utilize an intelligent routing scheme based on a packet header and/or payload content examination to route the transfer of data to a “most-appropriate” electronic device connected to the set-top box.
