Patents by Inventor Arun Narayen Netravali

Arun Narayen Netravali has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9106431
    Abstract: The invention includes a method and apparatus for providing media content. The method includes duplicating each packet of an original packet stream for which an associated importance level satisfies an importance condition, inserting each duplicate packet within the original packet stream to form thereby a modified packet stream, and transmitting the modified packet stream toward a wireless terminal adapted for processing the modified packet stream for presenting the media content conveyed by the original packet stream. The duplicate packets may be inserted within respective windows associated with the duplicate packets, wherein each window is determined according to an original packet position associated with the original packet from which the duplicate packet is formed.
    Type: Grant

  • Patent number: 8612619
    Abstract: The invention includes a method and apparatus for providing multimedia content to a plurality of wireless terminals. The method includes transcoding an original media stream to form at least one companion media stream, each media stream having a different data rate, and advertising each media stream to each of the plurality of wireless terminals, each wireless terminal having an associated channel condition. The original media stream and at least one companion media stream are each adapted for being selected by each of the wireless terminals. For each wireless terminal selecting one of the media streams, the selected one of the media streams is selected using the data rates of the media streams and the channel condition of the wireless terminal. The transcoding of the media stream to form the at least one companion media stream may be performed using channel condition information.

  • Patent number: 8291102
    Abstract: The invention includes a method and apparatus for providing multimedia content. The method includes receiving, at a network element having a first buffer, a data stream conveying a media clip having an associated media bit rate, the media clip intended for transmission toward a wireless terminal having a second buffer, and transmitting the data stream toward the wireless terminal at a media transmission rate determined according to a data rate supported by a radio access network over which the data stream is transmitted toward the wireless terminal. The buffers bridge a mismatch between the media bit rate and media transmission rate. The wireless terminal may select one of a plurality of presentation modes, where the selected presentation mode controls streaming of the media clip to the wireless terminal and presentation of the media clip at the wireless terminal.

    Abstract: The invention includes a method and apparatus for providing media content. The method includes duplicating each packet of an original packet stream for which an associated importance level satisfies an importance condition, inserting each duplicate packet within the original packet stream to form thereby a modified packet stream, and transmitting the modified packet stream toward a wireless terminal adapted for processing the modified packet stream for presenting the media content conveyed by the original packet stream. The duplicate packets may be inserted within respective windows associated with the duplicate packets, wherein each window is determined according to an original packet position associated with the original packet from which the duplicate packet is formed.

  • Patent number: 7738476
    Abstract: The invention includes a method and apparatus for scheduling packet transmissions on a data channel from a base transceiver station to a plurality of wireless terminals. The method includes, in response to detecting an available timeslot, computing utilization evaluation values for the respective media sub-streams using data rate feedback information from the wireless terminals and respective average data rates associated with respective media sub-streams, selecting one of the media sub-streams having an associated utilization evaluation value indicative of a best available channel utilization for the data channel, and transmitting a packet from the selected media sub-stream toward at least one wireless terminal belonging to a media sub-group associated with the selected media sub-stream. An average data rate associated with each media sub-stream is updated at each timeslot.
