An improved high-frequency filter has an adjustment or sliding device for adjusting the coupler bandwidth. The adjustment or sliding device is attached to at least one coupling element. The coupling element is associated with a coupler opening relating to a resonator. The coupling element is related to an associated coupler opening arranged in the resonator such that a means of adjustment and thus the coupling element is adjustable between two extreme settings through adjustment of the adjustment or sliding device in which the coupling element is fully or partially slid into the coupler opening or fully or partially slid out of the coupler opening or is moved or positioned away from the coupler opening.
A system and method that utilize a learning system to maintain a set of geographical locations indicating an area where network data coverage is poor. When it is determined that a client device is moving towards such an area, the client is forced or instructed to switch to a lower delivery bitrate for video segments in order to force the client's Adaptive Bit Rate (ABR) playback buffer to fill itself with enough low-quality video segments to enable the client to cross the area without video playback interruption. Thus, the client mobile device may be preemptively forced to choose the lowest bitrate specified in a manifest file for the delivered video segments as the bitrate for downloading video segments when approaching the poor coverage area. Hence, the client device can maintain a minimum level of Quality of Service (QoS) when moving through network areas with poor data coverage.

Responsive to monitoring the video buffer characteristics of the media player during the streaming session, a selected single bitrate may be moved up or down to other bitrates of the manifest files.

A multiplex filter has at least n filter chambers which are surrounded by a housing and/or at least one insert positioned in the housing. A metal dividing device is constructed in each of the n filter chambers, dividing each filter chamber into m resonator chambers, wherein m≥2.

A common connection is guided into the first filter chamber via a first opening in the housing, and is coupled in the same to the m resonators of the m resonator chambers. As a result of the fact that the coupling is established perpendicular to the H field, the resonator can have a very compact construction.

Thereafter, the particular MABR stream may be joined to facilitate streaming of the requested channel via the QAM serving the subscriber station.
