  • Publication number: 20090328096
    Abstract: 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.

  • Patent number: 7590237
    Abstract: A system and method are described for greatly increasing the number of services that can be encrypted with existing conditional access equipment. The method is most useful when many digitally compressed programs are encrypted at the same time. Only the most critical components of each compressed video, audio, or data stream are selected and then sequenced into a single stream. Additional formatting causes this sequence of segments from multiple sources to appear as a single continuous stream to the conditional access system. Once this stream has been encrypted, it is demultiplexed and the components are restored and re-sequenced into their respective programs. Messages such as the Entitlement Control Messages that are inserted into the stream by the encryption system, are also adjusted and included with each of the reconstructed programs.

  • Publication number: 20090138966
    Abstract: 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.

  • Publication number: 20080068997
    Abstract: The present invention provides a balanced video distribution system, as well as corresponding methods and apparatus, which utilize feedback from the channel multiplexers as well as rate estimation and predictive rate control. Packets of a video stream are received at an input buffer. A transmission deadline is determined for the packets. A fullness level of the input buffer is also determined. A future time at which said packets can be transmitted may be estimated based on the buffer fullness level. A bit rate of the video stream can be adjusted based on the estimated future time and the transmission deadline. For example, the bit rate may be adjusted in proportion to a difference between the estimated future time and the transmission deadline.

  • Publication number: 20060165088
    Abstract: The present invention relates generally to the processing of multiple data streams with common resources. More particularly, this invention relates to a technique for time-multiplexed processing o, for example, multiple digital video programs. In one embodiment, an exemplary method provides for time-multiplexed processing of a set of digital streams includes storing each received packet in a random access memory. For each stream, the deadline for the arrival of the next packet at the receiver is determined and a priority based on the deadline is assigned. The stream with the highest assigned priority is identified as an identified stream. In some embodiments, the processing state of the identified stream is then restored. One or more packets of data corresponding to the identified stream are retrieved from random access memory to produce retrieved packets. The processing state is saved after the retrieved packets have been processed.

  • Publication number: 20060088284
    Abstract: The present invention provides systems and methods for automating the conversion of digital images from a first storage media used by digital cameras to a second storage media used by computers and video playback devices. The conversion can be performed by a self-contained kiosk which detects the insertion of the first storage media containing the images in a first format. A processor at the kiosk converts the images into a second format (e.g., one that is compatible with video playback devices such as a DVD player). The images may then be copied to and stored on a second storage media in both the first (original) format and the second format. The second storage media is then dispensed from the kiosk. The resulting second storage media is compatible with video playback devices and serves as a master negative.

  • Patent number: 6996129
    Abstract: An advanced multiplexer designed and optimized for next generation on-demand video distribution is described. Features and capabilities include auto-discovery, channel-staggering and compatibility with static Virtual Channel Tables (VCTs). The multiplexer system facilitates auto-discovery by inserting identifiers into MPTSs (Multi-Program Transport Streams). These identifiers are echoed back to the multiplexer by the client set-top thereby indicating correspondence between modulators, service groups, and clients. When modulating multiple channels, FEC frames (Forward Error Correction frames) are staggered across channels to reduce correlation and clipping in the IFFT processor.

  • Publication number: 20040160971
    Abstract: According to one embodiment of the present invention, a method combines a set of digital streams into a set of digital multiplexes. This can include, for example, identifying a first communication channel that is currently accepting packets at a rate that can cause the nominal capacity of the channel to be exceeded. A second communication channel that is currently accepting packets at a rate that is less likely to cause the nominal capacity of the channel to be exceeded is also identified. One or more of the streams that comprise the multiplex that is assigned to the first communication channel are selected to form selected streams. Further, the packets of the selected streams can be reassigned from the multiplex corresponding to the first communication channel to the multiplex corresponding to the second communication channel.

  • Patent number: 6434748
    Abstract: An apparatus for providing VCR-like “trick mode” functions, such as pause, fast-forward, and rewind, in a distributed, video-on-demand program environment. Trick modes are supported by locally altering the viewing speed for each user who requests such functions, without affecting the operation of the central data source in any way. Thus, a virtual unlimited number of viewers are able to enjoy random access to video programming, including virtually continuous trick mode functionality. This is accomplished in a manner that is operable with existing telephone and cable distribution infrastructure.
