Techniques discussed herein improve a user's playback experience of a multimedia file by automatically adjusting playback settings based on change history data stored in one or more profiles. A system is configured to detect and collect information regarding changes to playback settings made by one or more users, and/or made in response to input from one or more users, during presentation of a media title, such as a song and/or movie, on one or more computers. This information is processed by a backend process on one or more server computers to determine predicted preferred playback settings for a particular user using a particular computer or playback device, requesting a particular multimedia file.

Provided herein are systems and methods for providing insights or metrics in connection with provisioning applications and/or desktop sessions to end-users. Network devices (e.g., appliances, intermediary devices, gateways, proxy devices or middle-boxes) can gather insights such as network-level statistics. Additional insights (e.g., metadata and metrics) associated with virtual applications and virtual desktops can be gathered to provide administrators with comprehensive end-to-end real-time and/or historical reports of performance and end-user experience (UX) insights. Insights relating to an application or desktop session can be used to determine and/or improve the overall health of the infrastructure of the session, Citrix Virtual Apps and Desktops, the applications (e.g., remote desktop application) being delivered using the infrastructure, and/or the corresponding user experience.

A method and apparatus for playing a media file are disclosed. The method includes determining whether a resource-substitution process needs to be performed; and selecting a substitute resource from a candidate resource set to replace an original resource in the media file to play, when the resource-substitution process needs to be performed.

Various embodiments of the present disclosure provide a method for transmission configuration. The method which may be performed by a network node comprises determining one or more uplink transmission parameters for a terminal device based at least in part on downlink information reported by the terminal device. The method may further comprise transmitting configuration information to the terminal device to indicate the one or more uplink transmission parameters.

A method and apparatus for fast communication between the master and the slave connected via Bluetooth low energy (BLE) is provided. An electronic device includes a communication circuit configured to perform wireless communication, a processor operatively connected to the communication circuit, and a memory operatively connected to the processor, wherein the memory may store instructions that, when executed, cause the processor to receive a first designated message associated with a connection parameter update through the communication circuit from an external electronic device connected via a Bluetooth low energy (BLE) protocol, determine, in response to reception of the first designated message, a designated scheme for the connection parameter update based on an attribute of the external electronic device, determine a time point of an instant based on the determined designated scheme, transmit a second designated message including the determined instant time point to the external electronic device, and update connection parameters.

A communication method includes a first device configuring a plurality of buffers to compress data packets. Each of the plurality of buffers is used to compress one or more data packets for transmission. If a compressed data packet is lost during transmission, a receive end cannot decompress a data packet corresponding to a same buffer as the lost data packet, but the receive end can continue to decompress a data packet that does not correspond to the same buffer as the lost data packet.

Provided are a link establishment method and apparatus and a computer-readable storage medium. The link establishment method includes: exchanging optical link auto-negotiation information with a terminal device through an optical link auto-negotiation channel; and in a case where exchanging the optical link auto-negotiation information is finished, establishing at least one of a traffic data channel or an optical link auto-negotiation channel; where the optical link auto-negotiation channel is independent of the traffic data channel or the optical link auto-negotiation channel; and the optical link auto-negotiation information includes at least one of information about an operating wavelength channel of the terminal device, an enabled or disabled state of forward error correction with the terminal device, a forward error correction type with the terminal device, or an operating mode of the auxiliary management channel.

A system and method are provided for implementing unique multi-band service discovery protocols between communicating devices, including wireless communicating devices supporting operations according to multiple standards and in different frequency bands, particularly in peer-to-peer or ad hoc networking schemes. The disclosed systems and methods define within each service discovery frame, whether a service discovery query or a service discovery response, an indication of the frequency band and/or channel that may support a specific service indicated by the service discovery frame. Cooperating communicating devices between which communications are to be established supporting a specific service protocol are provided with a mechanism by which to identify which common frequency bands and/or channels the communicating devices may communicate in executing the specific service.
