In the preferred embodiment, an identifier associated with the program's channel (52) is used to identify a source device (26, 28, 30 or 34). When a user selects a program (60 or 62) listed in displayed schedule information (50), the system (10) reads the source identifier attached to the program's channel (52). The system (10) then carries out an automatic switching/tuning such that the required source device (26, 28, 30 or 34) is input to the destination device (22), and a tuner is then tuned to the selected program's channel (52)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-source switching in a television system","description":"The present invention provides a tuning scheme for coordinating schedule information and programs received from multiple sources (26, 28, 30 and 34).
