A method for allowing user selection of interactive video software components in a television STB operatively coupled to a video content network includes the steps of: affording the user a selection of interactive video software components to run on the set-top box; and loading selected interactive video software components onto the set-top box. The selected interactive video software components are delivered from a remote node over the video content network to which the STB is coupled.

An endoscope system includes: an endoscope including an image pickup device provided in an insertion portion, and configured to pick up an image of a subject to output a binary image signal; a multilevel modulation unit configured to output, through a predetermined transmission path, a multilevel signal obtained by performing multilevel modulation on the binary image signal; and a memory configured to store endoscope information on signal transmission; and a processor including a multilevel demodulation unit configured to receive the multilevel signal through the predetermined transmission path, and obtain and output the binary image signal by multilevel demodulation; and a controller configured to read the endoscope information from the memory, and determine a multilevel number in the multilevel modulation by the multilevel modulation unit based on the endoscope information read to control the multilevel modulation unit.

Aspects of the disclosure include an apparatus at base station side in a wireless communication system for multi-user superposition transmission. The apparatus includes a superposition control unit and an indication generation unit. The superposition control unit is configured to insert, into a data stream of each user equipment in a group of user equipment comprising a plurality of user equipment, a demodulation reference signal corresponding to the data stream, and superpose demodulation reference signals corresponding to data streams of respective user equipment. The indication generation unit is configured to generate, for at least a first user equipment among the plurality of user equipment, an indication regarding a demodulation reference signal corresponding to a data stream of other user equipment among the plurality of user equipment, to assist the first user equipment in demodulating data transmitted in the multi-user superposition transmission.

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.
