Abstract:
A data communication architecture delivers a wide variety of content, including audio and video content, to consumers. The architecture employs channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architecture communicates content according to an initial bonding configuration. The communication architecture may adjust the bonding configuration to adapt to bonding environment changes affecting the communication capabilities or requirements associated with transmitting the content.

Abstract:
An apparatus and method for converting an IP-based multimedia channel and distributing the channel to a plurality of non-IP enabled devices based on the channel's popularity among the devices. The apparatus identifies a plurality of multimedia channels requested by a group of devices, and determines a data rate for providing each channel to the devices based on a popularity of each channel among the devices. The apparatus uses an adaptive bit rate (ABR) client to receive content segments for a respective one of the multimedia channels from an ABR server at a source data rate aligned with a determined data rate for providing the respective multimedia channel. The content segments are received at the source data rate, and converted by the apparatus to a continuous digital content stream. The apparatus then provides the continuous digital content stream to one or more of the devices at the determined data rate.
Abstract:
A data communication architecture delivers a wide variety of content, including audio and video content, to consumers. The architecture employs channel bonding to deliver more bandwidth than any single communication channel can carry. The architecture includes intermediate network devices that may receive content and send content using different groups of communication channels. The network device may process content received across a first set of communication channels for transmission across a second set of communication channels different from the first set. Such processing may preserve a program order of the content during delivery to a destination device.
Abstract:
Different data communication architectures deliver a wide variety of content, including audio and video content, to consumers. The architectures employ channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architectures distribute video programming in the form of MPEG2 TS packets, flagged by marker packets, in a round-robin manner across the communication channels. Channel bonding synchronization information may be present in packets defined above the data-link layer or added to fields within data-link layer frames.
Abstract:
Different data communication architectures deliver a wide variety of content, including audio and video content, to consumers. The architectures employ channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, different network types may be channel bonded to function as a single logical channel.
Abstract:
A distributed adaptive bit rate (ABR) proxy system may include a gateway device that includes a first transcoder and is configured to receive segments of a content item from an ABR server, and a secondary device that includes a second transcoder and is configured to receive the segments of the content item from the gateway device. The first transcoder may transcode the segments based at least in part on a first ABR profile to generate first transcoded segments, and the second transcoder may transcode the segments based at least in part on a second ABR profile to generate second transcoded segments. The gateway device may advertise the first and second ABR profiles to user devices and may transmit the first transcoded segments to the user devices in response to requests therefor. The secondary device may transmit the second transcoded segments to the user devices in response to requests therefor.
Abstract:
A system for presentation timing based audio video (AV) stream processing may include a switch device, a first processor, and a second processor. The switch device may be configured to route AV traffic to the first processor for processing and non-AV traffic to the second processor for processing. The first processor may receive transport stream packets that include an audio stream and/or a video stream. The first processor may receive a request to modify presentation timing of the audio stream and/or video stream. The first processor may modify the transport stream packets and/or presentation timing parameters of the transport stream packets based at least in part on the received request. The first processor may provide the transport stream packets to an electronic device. In some implementations, the second processor may be unable to access the content of the transport stream packets in the clear, e.g. due to security considerations.
Abstract:
A system for efficient memory bandwidth utilization may include a depacketizer, a packetizer, and a processor core. The depacketizer may generate header information items from received packets, where the header information items include sufficient information for the processor core to process the packets without accessing the payloads from off-chip memory. The depacketizer may accumulate multiple payloads and may write the multiple payloads to the off-chip memory in a single memory transaction when a threshold amount of the payloads have been accumulated. The processor core may receive the header information items and may generate a single descriptor for accessing multiple payloads corresponding to the header information items from the off-chip memory. The packetizer may generate a header for each payload based at least on on-chip information and without accessing off-chip memory. Thus, the subject system provides efficient memory bandwidth utilization, e.g. at least by reducing the number of off-chip memory accesses.
Abstract:
Systems and methods for transmitting content using segment-based and non-segment-based streams are provided. In some aspects, a method includes identifying at least one segment-based stream of content. Each segment-based stream is associated with a respective first bit rate and includes one or more segments of the content. The method also includes identifying at least one non-segment-based stream of the content. Each non-segment-based stream is associated with a second bit rate and includes a continuous stream of the content. The method also includes enabling switching between use of i) the at least one segment-based stream and ii) the at least one non-segment-based stream to continuously transmit the content to one or more client devices.
