Premises apparatus and methods for providing aggregated high-bandwidth, low-latency data service over a content delivery network including existing wireline infrastructure. In one embodiment, a network architecture having service delivery over at least portions of extant hybrid fiber coax (HFC) infrastructure is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 3GPP and IEEE Std. 802.11 services) via a common service provider. In one variant, an expanded frequency band (e.g., 1.6 GHz in total bandwidth) is used over the coaxial portions of the HFC infrastructure, which is allocated to two or more sub-bands. Premises apparatus are used to support multi-service integration (e.g., aggregation of mobile wireless, premises, and other services), as well as incipient IoT applications and technologies.

A method and test instrument for validating MPEG content in a CATV network, particularly one having a Remote PHY architecture.

Approaches provide for processing a communications signal, such as a wideband communications signal. For example, a communications signal can be received at an access device, such as a cable modem or a wireless transceiver/radio. The access device can include components operable to process the communications signal to enable access to, for example, video, data, voice, high-speed Internet services. At least some of the components include an echo cancellation component among other components to cancel interference (e.g., ACI, ALI). For example, the echo cancellation component can use trained filters and samples of the upstream signal, echoed samples of the transmitted signal, feedback signals of the echoed signal, etc., to estimate one or more types of interference. Thereafter, the estimated interference can be used to cancel interference at the access device.

An electronic device including: one or more processors to control operations thereof, to simultaneously process multiple wireless signals received from a plurality of multimedia devices transmitting streaming media content and to transmit the processed wireless signals to another one of the plurality of multimedia devices; a storage device to store received broadcast media content; and a network controller to wirelessly receive streaming broadcast media content from a plurality of broadcast media sources, to provide a wired and a wireless connectivity to the plurality of multimedia devices, to exchange media processing capabilities between the electronic device and the plurality of multimedia devices after establishing network connections therebetween, to receive a wireless signal including streaming media content from at least one of the plurality of multimedia devices, and to stream a processed version of the received wireless signal including streaming media content to another one of the plurality of multimedia devices, the processed version of the received wireless signal including streaming media content being processed based on the received media processing capabilities of the multimedia device receiving the transmitted wireless signal including streaming media content.

A controller receives an encrypted media stream (“EMS”) and an identifier indicative of a selected content key from a headend. The EMS is encrypted with an encryption key and can be decrypted with a corresponding decryption key which is determinable from the selected content key. The controller receives indexes and content keys from the headend prior to receiving the EMS. Each index respectively corresponds to an identifier with one index corresponding to the identifier indicative of the selected content key. The content keys correspond to the indexes with one content key corresponding to the index corresponding to the identifier indicative of the selected content key. The controller selects the index corresponding to the identifier indicative of the selected content key upon receiving the EMS, determines the selected content key from the selected index, determines the decryption key from the selected content key, and decrypts the EMS with the decryption key.

Systems and methods for rewinding a video to a point before the video was first viewed. Video transmitted by a media source is cached by a remote server. Upon a trick-play request for the video, the server generates a rewind stream that includes the video that was transmitted by the media source before the user started to view the video. Upon receiving the rewind stream, the user's equipment may cache the rewind stream in a rewind buffer and rewind or play from the rewind buffer. The server may also generate and transmit a forward stream of the video that the media source has not yet transmitted. The user's equipment may cache the forward stream in a forward buffer. To perform trick-play operations with the video, the user's equipment may migrate the playback of the video to the rewind and forward buffers and rewind or fast-forward the video from the buffers.

A method, apparatus, and system of pause and replay of media content through bookmarks on a server device are disclosed. In one embodiment, a method of a server device includes authenticating a user of a client device, communicating a media content to the client device through a network, processing a pause request of the client device to pause the media content, storing a bookmark location indicating a current playback location of the media content in the client device on the server device, processing a play request of the user to play the media content from the bookmark location (e.g., the play request may be received from a different client device of the user), and communicating the media content from the bookmark location to the user.

A cable modem transceiver includes a processor configured to derive an instant of time for an upstream calibration signal on basis of upstream scheduling information. Further, the cable modem transceiver includes a transmitter configured to generate the upstream calibration signal at the derived instant of time. The cable modem transceiver additionally includes a detector configured to determine a property of the generated upstream calibration signal. The processor is further configured to derive at least one calibration parameter for the transmitter on basis of the detected property.

A network element of a cable television (CATV) network, said network element comprising one or more amplifier units for amplifying downstream signal transmission for digital output into one or more output channels; means for detecting output power of all active digital output channels; means for providing a predetermined correlation between the detected output power of said active digital output channels and a corresponding minimum bias current for said one or more amplifier units; and means for adjusting the bias current of said one or more amplifier units on the basis of the predetermined correlation.

A network element of a cable television (CATV) network, said network element comprising one or more amplifier units for amplifying downstream signal transmission for digital output into one or more output channels; means for detecting modulation error ratio (MER) of all active digital output channels; and means for reducing bias current of said one or more amplifier units from a predetermined value until the MER value reaches a predetermined minimum value.
