Abstract: A receiver receives a first message including a first PDCP SN. The receiver may receive a second message including a second PDCP SN. The receiver may derive a second RTP SN based on at least one of a first RTP SN of the first message, the first PDCP SN, the second PDCP SN, or an RTP SN field of a second PDCP header composing the second message.

Abstract: 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.

Abstract: This disclosure is directed to systems and methods of data partitioning in image encoding. A video encoder may receive a single stream of video data that includes multiple layers. The video encoder may encode the one or more layers utilizing multiple counters for each component within the layers. The multiple counters may correspond to the header bits, luma bits, and chroma bits within each slice layer. The encoded layers may then be assembled into a single slice before it is sent to a decoder for decoding of image frame.

Abstract: Methods and systems for evaluating an audio quality using voice activity in a 4G and/or 5G network are disclosed. According to an implementation, a network component may determine that a voice call from a first user to a second user is established in a wireless network. The network component may include a user plane function in a 5G network and/or a serving gateway/packet data network gateway in a 4G network. The network component may obtain an audio stream associated with the voice call periodically until the voice call ends. The network component may further measure a packet loss rate of the audio stream, a muting rate of the audio stream, and a voice activity of the audio stream. The network component may determine whether the user perception of the voice call is impacted based at least in part on the packet loss rate, the muting rate, or the voice activity.

Abstract: Embodiments of the present disclosure provide a solution for media processing. A method for media processing is proposed. The method comprises: performing a conversion between a media file of a media and a media presentation of the media, wherein the media presentation comprises a main stream representation (MSR) and an external stream representation (ESR) associated with the MSR, a concatenation of a first segment in the ESR, a second segment in the MSR corresponding to the first segment, and subsequent segments following the second segment in the MSR results in a file conforming to a file format standard. Compared with the conventional solution, the proposed method can advantageously support the extended dependent random access point (EDRAP)-based technology more efficiently.

Abstract: A streaming media processing method, a transmitting device and a receiving device are provided. The streaming media processing method includes the following steps: encoding original media data into encoded streaming media; adding metadata to a media frame in the encoded streaming media to generate a padded streaming media, and the metadata serves as a payload data of the media frame; and encapsulating the padded streaming media into a streaming media packet. In this way, it is possible to satisfy the requirement of compatibility without affecting codec and communication protocols.

Abstract: Methods and systems provide dynamic adjustments for video optimization in a communication session. In one embodiment, the system receives a video stream from a transmitting device; transmits the video stream to one or more client devices, the first video stream having associated video transmission quality parameters; receives, from the one or more client devices, initial video display quality parameters related to the video stream; determines a video stream adjustment by comparing the video transmission quality parameters with the video display quality parameters; generates a modified video stream by applying the video stream adjustment to the video stream; transmits the modified video stream to the one or more client devices; receives, updated video display quality parameters related to the modified video stream; and compares the updated video display quality parameters to the initial video display quality parameters to determine that one or more video quality metrics have increased.

Abstract: The present disclosure relates to methods and devices for facilitating using a streaming manifest including a profile signal for content encoded based on a encapsulation format. An example method disclosed herein includes identifying structures associated with first media, wherein the first media is associated with a first streaming format. The example method also includes generating a streaming manifest for the first media, wherein the streaming manifest maps the structures associated with the first media to structures associated with a second streaming format, and including an indication with the streaming manifest, wherein the indication identifies the streaming profile used to map the structures.

Abstract: Methods and systems provided herein ensure that communication sessions established between select parties, and communication devices, are in complete compliance with a predefined condition, or precondition. Upon determining content and addressing of a communication session, at least one precondition for communications is retrieved from a memory device. The precondition corresponds to a required condition for a communication session to be enabled and maintained. Once the precondition is met, the communication session is established and, as long as the precondition remains intact, the communication session is allowed to be maintained. Ensuring that the precondition exists and remains intact includes embedding an authentication signal, that is based on the precondition, along with communications made in the communication session. When at least a portion of the precondition is no longer met, the communication session is instantaneously terminated.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to monitor streaming media. An example apparatus includes memory, instructions in the apparatus, and processor circuitry to execute the instructions to: calibrate video data based on audio data, the video data and the audio data associated with a media stream, generate a signature representative of the media stream based on the calibrated video data, compare the signature to a signature database to identify a matching signature in the signature database; and credit media corresponding to the matching signature as being viewed.
