| 20110126248 | MANAGED MULTIPLEXING OF VIDEO IN AN ADAPTIVE BIT RATE ENVIRONMENT - Methods and apparatus for delivering video programs are provided. A plurality of video programs are provided in a fragmented, adaptive bit rate format. A request for a respective video program from the plurality of video programs is received from each of a plurality of clients. The requested video programs are multiplexed for delivery to the clients in a multiplex over a shared, fixed-bit-rate transmission channel. The requests may be for the same or different video programs. The requests for the video programs may occur at the same or at different times. In the fragmented, adaptive bit rate format, the fragment delivered to the client may not be the same as the requested fragment and is dependent on multiple criteria, including the bitrate and quality of the requested and delivered fragments, the total available delivery bandwidth, and other fragment requests made on the channel. The resulting multiplex may be either a constant bit rate multiplex or a variable bit rate multiplex. | 05-26-2011 |
| 20100333149 | DELIVERY OF PRE-STATISTICALLY MULTIPLEXED STREAMS IN A VOD SYSTEM - Methods and apparatus are provided for delivering a plurality of video on demand (VOD) streams to customers. Video streams are received from a VOD server. The received streams are statistically multiplexed to transrate them and to optimize their video bandwidth. The statistically multiplexed streams are modulated, and then delivered to customers as single program transport streams. | 12-30-2010 |
| 20100253847 | TWO-STAGE DIGITAL PROGRAM INSERTION SYSTEM - Apparatus and methods are provided for inserting advertisements and/or to perform grooming functions after a video, audio and/or data stream has been transrated and/or encrypted. In this manner, ad insertion and grooming can be performed close to the edge of a video distribution network. Transrating and encryption of a program into which content is to be later inserted can be accomplished before the program is transmitted. Thus, a single encrypted version of a program can be transmitted from a central point in the network to multiple recipients, while providing the benefits of subsequent targeted ad insertion or grooming downstream of the central point. | 10-07-2010 |
| 20090328096 | PRECONDITIONING AD CONTENT FOR DIGITAL PROGRAM INSERTION - Methods are provided for inserting advertisements or the like and/or to perform grooming functions for a video, audio and/or data stream. Video programming is received in a network stream. Alternate content, such as advertisements, is received in content stream. The content stream is preconditioned to provide an entrance point therein for splicing the network stream to the content stream. Preconditioning of the content stream can also be performed to provide an exit point for splicing back to the network stream when the alternate content (e.g., advertisements) has concluded. | 12-31-2009 |
| 20090138966 | Advanced, self-balancing video multiplexer system - An advanced video multiplexer system designed and optimized for next generation on-demand video distribution is described. The system optimizes identifies a multi-program transport stream best able to accommodate new sessions based upon Quality of Service (QoS) and QAM utilization ratios. MPTS channels are rebalanced via re-grouping and transrating as necessary to optimize bandwidth utilization. Multiple video formats are supported via built-in transcoding. The multiplexer manages encryption resources and supports new sessions using previously allocated encryption resources where possible. Sessions can be grouped into encryption channels either by using a single authorization tier per channel policy, or by requiring all clients of the group to be in physically separated service groups. Encryption channels can be released when a channel no longer serves any clients or when one or more other channels that have been assigned the same entitlement can accommodate any remaining clients. | 05-28-2009 |
| 20080256417 | SDRAM convolutional interleaver with two paths - An SDRAM convolutional interleaver with two paths. Symbols are assigned to a given one of the two paths, then are sorted to minimize (to one) a number of breaks in a sequential Interleaver write address. After sorting, the symbols are stored staggered in SRAM and burst written to SDRAM. Before writing to SDRAM, data is accumulated for four symbols at a time, and the data is written four symbols wide to optimize SDRAM access time. 8 bit symbols are written 32 bits at a time to SDRAM. | 10-16-2008 |
