A system for generating, providing and/or receiving an encapsulated service guide data.

System and techniques for multiple stream tuning are described herein. A plurality of content streams may be received. The plurality of content streams may be ranked. A user attention level may be scored as the user observes at least one content stream of the plurality of content streams. The user attention level and a rank for the at least one content stream may be compared to remaining ranks of the plurality of content streams to produce a difference. A stream action may be performed on a set of content streams from the plurality of content streams based on the difference.

Wireless transport of multiple service versions of a transport framework. First and second information may be processed for transmission, respectively, according to first and second service versions of a transport framework. The first and second information may be encoded using a first type of error correction coding; after processing, the processed first information may include error correction coding according to the first type of error correction coding, while the processed second information may remain uncoded according to the first type of error correction coding. Control information may be generated indicating that the second information remains uncoded according to the first type of error correction coding, which may signal to receivers that the second information is processed according to the second service version of the transport framework. Packets including the processed first information, the processed second information, and the control information may be generated and transmitted in a wireless manner.

Various techniques include detecting noise in a network, identifying the type of noise in the network, localizing noise in the network, determining noise scores for network devices, and/or determining likelihoods that particular devices are causing noise and/or are in proximity of a point of entry of noise into the network.

An apparatus for capturing video broadcasting signals comprises a plurality of capture channels, each channel producing respective video transport streams as inputs to a multi-channel virtualization module. Each channel comprises: an input interface powered by a low-noise power supply arranged to receive a respective modulated video broadcasting input signal within an input frequency band; a single input, dual output distribution amplifier arranged to produce first and second amplified input signals within a satellite broadcasting frequency band and within a cable and/or terrestrial broadcasting frequency band, respectively. A first tuner is configured to receive and downconvert the first amplified input signal to generate a first baseband signal; a second tuner is configured to receive and downconvert the second amplified input signal to generate a second baseband signal; and a demodulator is configured to receive the baseband signals as input and to generate the respective video transport stream.
