  • Patent number: 11895352
    Abstract: Various embodiments are described herein for systems and methods that can be used to operate a media transmission network. In at least one embodiment, the media transmission network comprises a plurality of media processing devices configured to receive and process media streams based on control data. The media transmission network also comprises a controller coupled to the plurality of media processing devices and configured to generate a control signal for some or all of the media processing devices in the network. The controller is configured to determine the timing at which to transmit the control signal to a respective media processing device in order for the instructions in the control signal to be executed at the same time as the media data is received. The controller determines the transmission timing of each control signal by determining the latencies and delays of the network and the devices, such as, for example, network latency, processing delay, and/or control delay.

  • Patent number: 9755949
    Abstract: Some embodiments provide loop detection and loop prevention mechanisms for messaging passing in between peers in a multi-tier hierarchy. In some embodiments, the messaging header is modified to track which peers have received a copy of the message. Each peer appends its identifier to the message header before passing the message to another peer. When selecting a receiving peer, the sending peer ensures that the receiving peer is not already identified in the message header. If the receiving peer has already received the message, then another peer from a next-peer list is selected to receive the message. If all peers in the next-peer have been traversed, the sending peer returns an error message via a reverse traversal of the peers in the message header.

A first subset of the plurality of data packets is usable to generate a video display of content having a first quality and all of the plurality of data packets are usable to generate a second video display of the content having a second quality. The second quality is higher than the first quality. The signal-processing engine is further configured to distinguish the first subset of the plurality of data packets from other data packets of the plurality of data packets by applying a tag to particular data packets to form tagged data packets. The system also includes a transmitter coupled to the signal-processing engine and configured to transmit the plurality of data packets of the video data stream.

  • Patent number: 8949907
    Abstract: Methods and systems for cross-protocol time synchronization may comprise, for example, in a premises-based network, receiving, by a root node network controller in the premises, signals that conform to one or more first communications protocols, where the signals may be received from sources external to the premises. The received signals may be bridged to conform to a second communications protocol different from the first communications protocol. The bridged signals may be communicated to one or more networked devices within the premises-based wired network, where only signals conforming to the second communications protocol may be concurrently communicated in at least two frequencies, a first in a frequency range of the first communications protocol and a second in a frequency range of the second communications protocol, the frequency range used by the first communications protocol being different from and not overlapping with the frequency range used by the second communications protocol.

  • Patent number: 8938763
    Abstract: Personal content server apparatus and associated methods that allow a user (e.g., cable or satellite network subscriber) to access content, such as a video program, from a location outside the subscriber's network. In one embodiment, a personal content server streams the content to the subscriber over a network connection from the local e.g., (subscription) network to a remote network upon authorization by a content manager process. Various access, business or operational rules are applied depending on the content and delivery mode; e.g., to live video broadcast, video-on-demand (VOD), or archived content from the subscriber's digital video recorder (DVR) or networked PVR. In another variant, reservation information (for example program or asset ID information) is cached at a headend or hub server, thereby obviating the subscriber (or the network) having to access the subscriber's premises device. In yet another variant, a “virtual” CPE experience is provided for the remote user.

  • Patent number: 8914834
    Abstract: A source rate associated with a video bit stream (112) and a channel (140) rate associated with an LTE environment can be identified. The video bit stream (112) can be a Scalable Video Codec (SVC) of an H.264/MPEG4 Advanced Video Coding. The channel (140) rate can be associated with one or more segment bandwidth (142) rates. An enhancement path from an enhancement profile (332) associated with the SVC can be determined. The enhancement profile (332) can include one or more cumulative source rates and an associated enhancement options. The enhancement options can be a frame quantity, frame size, and a frame quality (122, 124, 126). The enhancement path can be a subset of nodes of the enhancement graph (400). The channel (140) rate can be matched to a cumulative source rate to a node within the enhancement path. One or more Network Abstraction Layer (NAL) units (144) with the appropriate enhancement values can be conveyed.

  • Patent number: 8910222
    Abstract: A user recovers and records multiple programs communicated simultaneously using a communications channel, e.g., QAM communications channel. The simultaneous communication may be by communicating, e.g., an MPEG-2 transport stream including data corresponding to multiple programs through a corresponding to QAM communications channel. Thus a user device, e.g., a set top box, is able to receive and record programs corresponding to multiple simultaneously broadcast programs using a single tuner. This allows a device to receive and record or display more programs at any given time, than the number of QAM tuners and/or receivers in the user device. Novel user interface features which facilitate a user's ability to identify and record multiple programs corresponding to a QAM channel are also described. Methods and apparatus for determining program to communication channel mappings based on user program recordation information are also described.

  • Patent number: 8898716
    Abstract: The present disclosure discloses a digital communication between the embedded cable modem (eCM) and embedded set-top box (eSTB) via a shared memory. The communication is carried out by packet transfer mechanism as per the protocol without adding any extra header overhead. The communication link is established between the eSTB and eCM mainly in layer 2 and partly in layer 1 according to an implementation of the OSI model. Further, eSTB is used as an eSAFE device coupled to eCM where the eCM and eSTB are considered to be placed on two SoCs with a separate CPU to each SoC (System-On-Chip) with a shared memory (via high speed data bus protocol). DMA (Direct Memory Access) engines are used to accelerate data transfer and to reduce load. DMA of only eCM, SoC is used to minimize hardware resources.
