Abstract: Television tuner emulation techniques are described. In an implementation, a television tuner is emulated through execution of software on a processing system by a computing device, the emulated television tuner includes functionality to obtain television content over an Internet Protocol (IP) based network. The functionality of the emulated television tuner is exposed to one or more applications that are executed by the computing device such that the application is not aware that the television tuner is emulated through execution of the software.

Abstract: Various arrangements for porting wireless network credentials, such as between television receivers, are presented herein. A remote control may be paired with a first television receiver, such as a host television receiver. Wireless network credentials may be provided to and stored by the paired remote control. The remote control can then be paired with a second television receiver, such as a client television receiver. The second television receiver can then receive the stored wireless network credentials from the remote control. The second television receiver can then connect with a wireless network using the received wireless network credentials, such as to communicate with the host television receiver or access the Internet.

Abstract: A network digital video recording (nDVR) system may take into account the capabilities of a requesting user's local DVR when managing network recordings. The user's local DVR may include a temporary buffer that is normally used to record what the DVR is tuned to, and may be used for local trickplay functionality such as pausing live television. The nDVR features described herein may track the usage of the user's temporary DVR buffer, and use that in determining what to stream in response to a user's playback request. The nDVR system can also determine if the user's local DVR has an unused tuner at a time of a program recording, and can instruct the user's local DVR to also tune to the program.

Abstract: 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.

Abstract: A method and apparatus for controlling tuners in a content distribution system is described. The method and apparatus receive a request from a user device for a program stream over a local network at a receiver device that includes a join request at a network address. The method and apparatus further identify a channel associated with the network address, the channel being one of the channels received by the receiver device from a content service provider. The method and apparatus also determine if the identified channel is already tuned by a tuner in the receiver device. The method and apparatus additionally tune the channel using a tuner not currently being used if it is determined that the identified channel is not already tuned and provide the program stream from the tuned channel at the network address to the user device.

Abstract: In situations where a receiver, rendering a content, switches from a first transport stream carrying that content to a second transport stream carrying that same content, artefacts may occur on the rendered content while transitioning between both transport streams. Considering transport stream data of a transport stream signal may be available at a nominal frequency higher than a frequency corresponding to the transport stream bitrate, there may be some periods of time during which no data is present in the transport stream signal. A salient idea is to switch from the first transport stream signal to the second transport stream signal in such periods during which there is no transport stream valid data in the first transport stream signal, allowing to minimize the risks of perceptible defects in the rendered content throughout the switching.

Abstract: In one example, a remote tuner module includes: a first tuner to receive, process and demodulate a first radio frequency (RF) signal to output an analog audio signal, and to receive and process a second RF signal to output a first downconverted modulated signal; a second tuner to receive and process the second RF signal to output a second downconverted modulated signal; a demodulator circuit coupled to the first and second tuners to demodulate and link the first and second modulated signals, to output a linked demodulated signal. The remote tuner module may further include a gateway circuit coupled to at least the demodulator circuit to output the analog audio signal and the linked demodulated signal.
