A communication apparatus determines, in a case where connection with an external apparatus is disconnected, whether the disconnection is performed by the external apparatus. In a case where reconnection to a network is performed after connection to the external apparatus is disconnected and it is determined that the disconnection is not performed by the external apparatus, a communication unit is controlled to maintain a limitation for communication with another external apparatus and to transmit a reconnection notification to the external apparatus by unicast. In a case where reconnection to the network is performed after connection to the external apparatus is disconnected and it is determined that the disconnection is performed by the external apparatus, the communication unit is controlled to communicate with the other external apparatus without the limitation.

Implementations disclose leveraging aggregated network statistics for enhancing quality and user experience for live video streaming from mobile devices. A method includes receiving, by a processing device of a client device, a bandwidth parameter corresponding to aggregated network statistics for at least one of a current geographic location of the client device or a current network of the client device, initializing an upload quality parameter of an upload session based on the received bandwidth parameter, the upload session comprising upload of content from the client device, and modifying, by the processing device, the upload quality parameter throughout the upload session based on updated bandwidth parameters corresponding to aggregated network conditions for at least one of new geographic locations of the client device or new networks of the client device, the upload quality parameter to control a format of the upload session.

The present invention relates to systems and methods suitable for real-time streaming over a decentralized or centralized network. In the decentralized network, the present invention relates to a system and method that utilizes a block-chain distributed network to securely and reliably stream multimedia in real-time. In the centralized network, the present invention utilizes a centralized stream manager to manage nodes within the distributed network to securely and reliably stream multimedia in real-time.

A system for improved transmission of digital data includes: an incoming data stream having an incoming data rate rate.sub.IN; a memory configured to store the data; and a controller configured to write the data to the memory, the controller further configured to generate an outgoing data stream having an outgoing data rate rate.sub.OUT, wherein a normalized rate difference rate.sub.DIFFERENCE=(rate.sub.OUTrate.sub.IN)/rate.sub.IN between the incoming data rate rate.sub.IN and the outgoing data rate rate.sub.OUT is a negative number of parts per million (ppm).

A plurality of customer premises equipment devices in a broadband network are periodically polled to determine a corresponding upstream interface port for each of the plurality of customer premises equipment devices. The determined corresponding upstream interface ports for each of the plurality of customer premises equipment devices are compared to stored data indicating authorized upstream interface ports for each of the plurality of customer premises equipment devices. Responsive to the comparing indicating that at least one of the determined corresponding upstream interface ports does not match a corresponding one of the authorized upstream interface ports, at least one remedial action is taken for a customer account associated with a corresponding one of the customer premises equipment devices in the broadband network.

A method for channel downloading for zapping from one digital channel to another channel in a decoding member to decode a channel and to transmit it to a screen, the decoding member including a downloading module including an activity state, wherein the method includes in the activity state downloading a first viewing channel in an activity quality and another channel in parallel with the first channel, the downloading being done according to an activity bit rate. The downloading module further includes an inactivity state having a downloading inactivity bit rate lower than the activity bit rate. The method includes in the inactivity state, downloading the first channel in the activity quality, receiving a signal of a channel change early warning sign, changing the state of the downloading module by switching from the inactivity to the activity state when the signal of a channel change early warning sign has been received.

A network test instrument is operable to conduct sweep tests with a cable modem termination system having a distributed architecture. Through signaling performed via a telemetry channel between the network test instrument and a sweep server, the network test instrument can initiate the sweep test. The sweep server communicates with the cable modem termination system to facilitate the sweep test between the network test instrument and the cable modem termination system.

A system for improved transmission of digital data includes: an incoming data stream having an incoming data rate rate.sub.IN; a memory configured to store the data; and a controller configured to write the data to the memory, the controller further configured to generate an outgoing data stream having an outgoing data rate rate.sub.OUT, wherein a normalized rate difference rate.sub.DIFFERENCE=(rate.sub.OUTrate.sub.IN)/rate.sub.IN between the incoming data rate rate.sub.IN and the outgoing data rate rate.sub.OUT is a negative number of parts per million (ppm).

A management device includes a storage management unit configured to store, in a storage unit in accordance with a priority, a plurality of pieces of transmission data having corresponding time information among a plurality of pieces of transmission data generated by dividing a plurality of pieces of content data each encoded for a channel.

The present disclosure discloses a method and an apparatus for transmitting data of a mobile terminal. The method includes: obtaining cached data of a mobile application on the mobile terminal from an uploading cache, the cached data being coded and synthesized streaming data; obtaining a cache ratio of the cached data while in an online state, the cache ratio being a ratio of the cached data to the entire uploading cache in real-time; determining whether the cache ratio exceeds a preset cache ratio threshold; adjusting a bitrate of the cached data to obtain an adjusted bitrate if it is determined that the cache ratio exceeds the preset cache ratio threshold; and transmitting the cached data to a receiving terminal according to the adjusted bitrate while in the online state with a network, so that the receiving terminal plays, according to the cached data, live content corresponding to the cached data.
