Recorded broadcast programs, including advertisements, are selected for playback responsive to user input. The user input may include pressing a button multiple times to cause recorded programs to be scanned through for a particular preset channel from newest recorded to oldest recorded. Pressing another button multiple times causes the recorded programs to be scanned through for the particular present channel from oldest recorded to newest recorded.

System and methods related to video information distribution are provided. The system may obtain a video source address. The system may receive a video segment of a video stream from a remote server configured with the video source address. The system may parse the video segment for header information. The system may determine that a video corresponding to the video source address is playable on a remote device in response to the header information being included in the video segment. The system may store the video source address in a database. The database may include a plurality video addresses corresponding to respective videos that are playable on the remote device.

A receiving device including a first electronic component and a second electronic component. The first electronic component includes: an analog audio demodulator that demodulates a received signal including a digital broadcast wave and an analog broadcast wave to output an analog audio, the analog broadcast wave being broadcast later by a preset first delay time than the digital broadcast wave; and a transmitter that transmits a communication signal including the analog audio and the received signal to the second electronic component. The second electronic component includes: a receiver that receives the communication signal from the transmitter; a digital audio demodulator that demodulates the received signal included in the communication signal to output a digital audio; and a selector that selects at least one of the digital audio and the analog audio as an output sound signal.

Recorded broadcast programs, including advertisements, are selected for playback responsive to user input. The user input may include pressing a button multiple times to cause recorded programs to be scanned through for a particular preset channel from newest recorded to oldest recorded. Pressing another button multiple times causes the recorded programs to be scanned through for the particular present channel from oldest recorded to newest recorded. Each time at least a portion of a recorded program is played back, the amount of time of the playback is kept track of. An advertisement credit is awarded for playback of the recorded program based on the amount of time of playback of the recorded program.
