Methods and systems for codec detection in video streams
Method and apparatus for carrying out the method receiving packets, each of the packets comprising a header and a payload. For a particular packet among the packets, the method includes processing at least the header of the particular packet to determine a flow associated with the particular packet; attempting to determine a payload structure based on the flow, the payload structure associated with transport of coded video data in the payload of the particular packet; and if the attempting is successful, repackaging coded video data contained in the payload of the particular packet into a new packet and forwarding the new packet to an external system or storing the new packet in memory.
AUTOMATED CACHING AND TABLING LAYER FOR FINDING AND SWAPPING MEDIA CONTENT
A system and method for automated caching and tabling for finding and swapping media content is disclosed. The system and method include at least: (a) detecting, by one or more computing devices, one or more media packets transmitted over a network, wherein the one or more media packets are associated with the media content; (b) generating, by the one or more computing devices, a profile for the media content based on characteristics of the one or more media packets; (c) generating, by the one or more computing devices, a hash value based on the profile; (d) transmitting for storage in a database, by the one or more computing devices, the hash value, the profile, and the one or more media packets; (e) detecting, by the one or more computing devices, one or more subsequent media packets sent over the network and addressed to a destination to determine that the one or more subsequent media packets are associated with the media content by comparing the one or more subsequent media packets to the profile via the hash value; and (f) based on the detecting in (e) the system and method can further include transmitting, by the one or more computing devices, the one or more subsequent media packets or the one or more media packets to the destination based on a predetermined criteria.
Function repository selection mode and signaling for cloud based processing
A method and system for processing media content in Moving Picture Experts Group (MPEG) Network Based Media Processing (NBMP) includes obtaining a list of function repositories, each function repository storing one or more functions for processing the media content, obtaining a descriptor identifying a location of each of the function repositories identified in the list of function repositories, selecting a function repository, from among the function repositories, according to a criterion, and processing the media content using a function included in the selected function repository.
PERFORMANT AD HOC DATA INGESTION
A video processing engine may receive a request for a video communication session, via a network to produce a video file key that is routed to the video camera. If the video camera is communicatively connected to a Wi-Fi 6 compatible wireless access point, it routes a high-quality video file to the Network Operation Center (NOC). Alternatively, using the video key file, the video camera generates message digests and watermarks that are embedded in a video camera generated high-quality video file and a degraded quality video file. The video camera routes, via the network, the degraded quality video file to the NOC, while the high-quality video file is uploaded to the NOC later. Subsequently, a video processing engine extracts the watermarks from the message digests of the video files and compares them to ensure that the high-quality video file correlates to the degraded quality video file.
Method, apparatus, and system for detecting video code stream
A method, apparatus, and system for detecting a video bitstream, and a non-transitory computer-readable storage medium are disclosed. The method may include: receiving a first feature value generated by a source node which transmits a video bitstream, where the first feature value is feature information of the video bitstream generated by the source node according to a preset rule; receiving a second feature value generated by another node which transmits the video bitstream, where the second feature value is feature information of the video bitstream generated by the another node according to the preset rule; determining whether the first feature value is consistent with the second feature value via comparison; and generating an alarm in response to a comparison result that the first feature value is inconsistent with the second feature value.
NARROWCASTING TO ONE-WAY SET TOP BOXES
Methods and systems of narrowcasting to a service group having one or more one-way set top boxes are shown and disclosed. The method may include receiving encrypted single program transport streams (SPTSs) from an encryptor, and receiving one or more session control signals for the SPTSs from a switched digital video (SDV) control system. The method may additionally include receiving service information (SI) packet identifiers (PIDs) for the SPTSs from a conditional access (CA) system, and updating the SI PIDs based on the one or more session control signals. The method may further include converting the SPTSs to narrowcast multiprogram transport streams (MPTSs) based on the one or more session control signals, and transmitting the narrowcast MPTSs and the updated SI PIDs to a plurality of edge quadrature amplitude modulation (QAM) devices.
Data distribution system, method and computer-readable storage medium
A data distribution system includes: an edge stream-pushing server configured to receive streaming media data packets sent by a stream pusher, serialize the streaming media data packets, and forward the serialized streaming media data packets to a plurality of central servers; a central server configured to cache the serialized streaming media data packets, if a serialized back-to-source request from the edge stream-pulling server is received, determine, a start position of to-be-transmitted streaming media data packets according to the serialized back-to-source request, and send the cached streaming media data packets to the edge stream-pulling server according to the start position; and an edge stream-pulling server configured to deserialize received streaming media data packets to restore the received streaming media data packets, and send the restored streaming media data packets to a user terminal.
Systems and methods for determining delay of a plurality of media streams
A system and method are provided for determining delay of a plurality of media streams. The system and method involve generating, at a source processor, a series of source time packets; transmitting, at the source processor, through a network, the series of source time packets as a source packet stream; generating, at a destination processor, a series of destination time packets; receiving, at the destination processor, through the network, the source packet stream; determining, at the destination processor, a transmission time for the source packet stream based on the source time data and the destination time data; and determining, at the destination processor, a relative synchronization error based on the source signature data and the destination signature data. Each source time packet includes source time data and source signature data. Each destination time packet includes destination time data and destination signature data.
