  • Patent number: 10645447
    Abstract: Embodiments of the present invention provide a fast channel change method and a fast channel change server. After receiving a fast channel change request of user equipment, the fast channel change server adjusts a time interval between a video packet and a corresponding audio packet in a channel multicast packet, and sends an adjusted channel multicast packet to the user equipment. In this way, an audio and video synchronization time after the user equipment receives a channel data packet is reduced.

    Abstract: An architecture is provided that can scale content resolution in order to mitigate errors in a provisioned service of a communication network, such as a wireless service or a femtocell service that integrates with DSL or other broadband carriers. The architecture can identify fault conditions relating to e.g., bandwidth oversubscription or symbolization integrity. Based upon such identification, the architecture can alter encoding format codecs of certain types of content in order to reduce their resolution/quality, thereby mitigating bandwidth oversubscription fault conditions or freeing up space (without necessarily increasing bandwidth) to insert additional FEC code.

  • Patent number: 10602158
    Abstract: A method and apparatus to maximize video slice size is described herein. The method packs as many macroblocks as possible within a capped-size slice, while preserving user-defined quality constraints. The probability to conform to the maximum slice size constraint may be adjusted according to a user-defined parameter. The method may be integrated into a rate control process of a video encoder. The method predicts whether encoding a macroblock with a quantization parameter exceeds a current slice size constraint. It further predicts whether encoding a given number of macroblocks with a given configuration of quantization parameters exceeds the current slice size constraint. The method then proceeds to encode the current macroblock either on a condition that encoding the given number of macroblocks with the given configuration of quantization parameters falls below the size constraint of the current slice or after determining that a new slice is needed.

The result of the checking is indicative of at least one transmission unit in the buffer preceding, in decoding order, any transmission unit in a sequence of transmission units not having been buffered in the buffer before the checking.

  • Patent number: 9113132
    Abstract: A system for recording a compressed video-audio stream includes a decoder for decoding the video and audio packets of the stream, a multimedia recorder for recording the video and audio portions of the stream, and a video frame editor. In one embodiment the multimedia recorder receives and ignores initial delta frames of the video portion of the stream while buffering the audio portion of the stream received until a first key frame arrives and is buffered and decoded and wherein upon receiving a command to record, the system writes a copy of the key frame at a predefined interval the first interval corresponding with the start of the recording of the audio portions of the stream, the write interval repeated successively until a next key frame arrives whereby the video and audio is then recorded as received.

  • Patent number: 9104345
    Abstract: First in, first out (FIFO) queues may be used to transfer data between a producer clock domain and a number of consumer clock domains. In one implementation, a control component for the FIFO queues may include a number of counters, corresponding to each of the consumer clock domains, each of the counters maintaining a count value relating to an amount of data read by the corresponding consumer clock domain. The control component may additionally include a credit deduction component coupled to the count values of the counters, the credit deduction component determining whether any of the count values is above a threshold, and in response to the determination that any of the count values is above the threshold, reducing the count value of each of the counters and issuing a write pulse signal to the producer clock domain, the write pulse signal causing the producer clock domain to perform a write operation to the FIFO queues.

  • Patent number: 9054972
    Abstract: A port monitor monitors network traffic that passes through a port of a switch. Frame flows routed through the switch are counted by hardware frame counting logic, which includes a content-addressable memory (CAM) and counters corresponding to various frame flows. Port monitor software includes logical containers (“buckets”), which are used to record and sort counts of the frame flows from hardware based on activity of the frame flows. Frame flow sorting is based on confidence building algorithms such that the thrashing of frame flows between buckets is reduced. Storage and sorting of the frame flows in software allows the activity level of any number of frame flows associated with the switch to be counted, regardless of hardware limitations on how many frame flows can be counted. This allows a real-time analysis of frame flows and a determination of frame flows that are major users of Fiber Channel bandwidth.
