A network management system manages the operation of a home security system in a communication network, such as a mesh network. The home security system can include multiple components such as a camera, a lighting device, a security alarm, a doorbell switch and doorbell chime, and a fingerprint sensor, which connect with the communication network to perform various operations. The network management system monitors environmental parameters of the communication network, such as parameters associated with the access points and components of the home security system, determines an access point to which a component of the home security system is to be connected for efficient operation of the home security system, and connects the component to the communication network via the determined access point.

An information processing device (10, 10A) includes a band requesting unit (162, 162A), an adjusting unit (164, 164A), and a transmitting unit (140). The band requesting unit (162, 162A) requests, according to a bandwidth necessary for transmitting information including a moving image, a use reservation of the bandwidth. The adjusting unit (164, 164A) adjusts, according to a result of the request by the band requesting unit and a reserved bandwidth, an information amount of information to be transmitted. The transmitting unit (140) converts the information with the adjusted information amount into a transmission signal and transmits the transmission signal.

Improved neural-network-based image and video coding techniques are presented, including hybrid techniques that include both tools of a host codec and neural-network-based tools. In these improved techniques, the host coding tools may include conventional video coding standards such H.266 (VVC). In an aspects, source frames may be partitioned and either host or neural-network-based tools may be selected per partition. Coding parameter decisions for a partition may be constrained based on the partitioning and coding tool selection. Rate control for host and neural network tools may be combined. Multi-stage processing of neural network output may use a checkerboard prediction pattern.
