Abstract: The present application discloses a method for connecting a user device to a network. The access apparatus may obtain a first IP address from a fixed broadband network and a second IP address from a mobile broadband network, where the first IP address corresponds to a fixed broadband network link, and the second IP address corresponds to a radio link. The access apparatus receives a first packet from a user device, where a source IP address of the first packet is an IP address of the user device. The access apparatus obtains a translated IP address according to a service type of the first packet. The access apparatus obtains a second packet by replacing the source IP address of the first packet with the translated IP address, and sends the second packet to a link corresponding to the translated IP address.

Abstract: Video playback quality detection methods, systems, and apparatuses are described. The method can include obtaining a first video data packet of a target video from a bearer network and obtaining a data byte quantity of first video data included in the first video data packet. The method may also include determining a buffer byte quantity stored in a video quality detection buffer. Furthermore, the method can include obtaining video frame data rate information corresponding to the target video and reducing the buffer byte quantity stored in the video quality detection buffer based on a video frame rate of the target video and the video frame data rate information of the target video. The method may further include determining a playback status of playing the target video on a video player, and determining video playback quality of the target video based on the playback status. According to the embodiments of the present invention, user experience and accuracy of the video playback quality detection method can be improved.

Abstract: An image processing method performed by image processing device having an operating system includes receiving, by an image processing module of the operating system, an instruction of a first application program to call the image processing module of the operating system, where the instruction carries a to-be-displayed image and a resolution of the to-be-displayed image. The image processing method further includes when the resolution of the to-be-displayed image is less than a first threshold, performing, by the image processing module, super-resolution processing on the to-be-displayed image, and displaying an image obtained after the super-resolution processing.

Abstract: Embodiments of the present application disclose a bandwidth control method and a bandwidth control device. The method includes: obtaining, by a bandwidth control device, an access request of a mobile terminal, where the access request is used to indicate that the mobile terminal requests to access the Internet by using a home gateway of a fixed terminal; obtaining, by the bandwidth control device, a first bandwidth of the fixed terminal, where the first bandwidth is a subscribed bandwidth of the fixed terminal; and adjusting, by the bandwidth control device, a bandwidth allocated to the fixed terminal from the subscribed bandwidth of the fixed terminal to a second bandwidth, where the second bandwidth is greater than the first bandwidth. In the embodiments of the present application, the impact of mobile terminal access on user experience of the fixed terminal can be reduced.
