Patent number: 9635318Abstract: The techniques related to providing a live program over the Internet are described. According to one aspect of the techniques, a data stream representing a live program is preprocessed to produce a plurality of substreams, each of the substreams comprising decimated samples of the data stream. The number of substreams is relatively large so that the bandwidth requirement for delivering one of the substreams is relatively low. With a group of seeding boxes receiving the substreams, a group of boxes in services are designated to receive the substreams from the seeding boxes, each of these boxes including the seeding boxes is able to support multiple outbound streams (e.g., greater than 2) so that there are enough data suppliers to service the ordering boxes or colonize more boxes to become the data suppliers. As a result, a live program can be timely serviced by peer boxes, significantly reducing the computation and bandwidth burdens on a server(s).Type: GrantFiled: October 30, 2014Date of Patent: April 25, 2017Assignee: VUDU, INC.Inventors: Sumankar Shankar, Prasanna Ganesan

Patent number: 9176955Abstract: Techniques for sharing data among a plurality of networked devices, also referred to network nodes, are discussed. To best use an available uploading bandwidth of a device sharing data with a receiving device, a portion of the data is uploaded within the available uploading bandwidth, and another portion of the data is uploaded from another device locally caching the same data. To satisfy the minimum transmission rate of the data to the receiving device, both portions of the data are concurrently uploaded from the two devices to the receiving device. In reference to a predetermined minimum uploading bandwidth and the available uploading bandwidth, the two portions of data are interleaved and must be reassembled to recover the data for consumption in the receiving device. A size of the first portion of the data is determined by a server in view of the available uploading bandwidth a designated supplying box has.Type: GrantFiled: April 1, 2006Date of Patent: November 3, 2015Assignee: VVOND, INC.Inventor: Prasanna Ganesan

Patent number: RE47364Abstract: In accordance with an embodiment of the present invention, a client device is protected against the execution of unauthorized software. The client includes a code authentication process that verifies the integrity of executable code, by generating and comparing a first hash value of the executable code with a known hash value of the original code. Furthermore, during boot-up, the client initializes a CPU exception vector table with one or more vector table entries. One or more, or all, of the vector table entries direct the CPU to execute the code authentication process prior to executing an event handler when an exception event occurs. Consequently, the code authentication process is virtually guaranteed to execute, thereby protecting against the execution of unauthorized code.Type: GrantFiled: March 16, 2016Date of Patent: April 23, 2019Assignee: VUDU, INC.Inventors: Edin Hodzic, Andrew M.
