Abstract: The present disclosure relates to data transmission methods, network devices. One example data transmission method includes: a first network node sends a first indication information to a second network node, the first indication information includes information about an uplink data volume of a buffer of a terminal device, or the first indication information indicates a relationship between an uplink data volume of a buffer of a terminal device and a predefined data volume threshold.

Abstract: Various methods and systems are provided for accelerated image rendering with motion compensation. In one embodiment, a method comprises calculating motion between a preceding image frame and a target image frame to be rendered, rendering a small image with a size smaller than a target size of the target image frame based on the calculated motion, and generating the target image frame at the target size based on the small image, the calculated motion, and a reference image frame. In this way, high-quality image frames for a video stream may be generated with a reduced amount of rendering for each frame, thereby reducing the overall processing resources dedicated to rendering as well as the power consumption for image rendering.

Abstract: The invention relates to a portable radio frequency (RF) receiver module, the portable RF receiver module comprising: a standardized interface for receiving a RF signal, which comprises a RF connector and which is configured to allow as well an electrical connection and a mechanical quick attachment of the portable RF receiver module to a corresponding standardized interface of an antenna; a preselector circuit which is coupled to the standardized interface for receiving RF signals and which comprises a filter and a selection apparatus, wherein the selection apparatus is configured to allow a selection of a predefined filter characteristic of the filter and to filter out predefined frequency bands of the received RF signals. The invention further relates to a portable antenna arrangement.
