Abstract: A preparation method and an application of a tailings-based zeolite@carbon dots-titanium dioxide (CDs-TiO2) composite photocatalyst are provided, which relates to the field of solid waste utilization technologies. The preparation method includes performing an acidification treatment on tailings powder and then roasting to obtain modified tailings powder; adding the modified tailings powder and titanium dioxide into lye to obtain mixed suspension; stirring and aging the mixed suspension under ultraviolet irradiation to obtain an aged suspension, performing a hydrothermal reaction on the aged suspension to obtain a product, filtering, washing and drying the product to obtain the tailings-based zeolite@CDs-TiO2 composite photocatalyst.

Abstract: An electronic device for processing real-time-streaming-protocol (RTSP) packets in a network to provide enhanced video-on-demand (VOD) services is provided. The electronic device includes a user interface, a non-transitory memory configured to store instructions including an application layer gateway (ALG) module and network service software, and a hardware processor. The hardware processor is configured to execute the instructions to store a list of mac-bridge clients that includes a MAC address and a MAC mask corresponding to each mac-bridge client, and determine whether at least one of the source and destination MAC address of a received RTSP packet is on the list. When at least one of the source and destination MAC address is on the list, the RTSP packet is processed using the network service software and a next RTSP packet is received; otherwise, the received RTSP packet is processed using the ALG module.

Abstract: Methods, systems, and computer readable media described herein can be operable to facilitate different reporting treatment for certain join requests received during a fast channel change. A gateway device may automatically detect the FCC (Fast Channel Change) via a configured interval. The gateway device may be configured such that if a subsequent IGMP (Internet group management protocol) join request was received within the configured interval since a previous join request, the previous join request may be ignored. According to the configuration of the gateway device, in a FCC, only the first channel and the last channel are reported, and the middle channel changes may be ignored.
