Abstract
Abstract In a television receiver including a plurality of RF input terminals (A,B,C), each of which having a respective scan list, means are provided for linking the lists to form a single scan list with a single wrap-around point, and for separating the linked list into separately accessible scan lists in response to a user-entered command. As the user scans through the channels and changes from one linked scan list to another, the appropriate RF input connector is automatically selected. <IMAGE>

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
384 words
A television receiver, comprising: a plurality of radio frequency (RF) signal input terminals (A,B,C), each of which receives a group of RF signals from respective RF signal sources; RF switch means (100) having a plurality of inputs, each of which is connected to a respective one of said RF input terminals (A,B,C), said RF switch means (100) having an output at which is developed one of said groups of RF signals selected from said RF signals at said inputs, said RF input switch (100) having a control input for receiving a first control signal (101) for selecting said selected group of RF signals; tuner means (102) coupled to said RF switch means (100) for receiving said selected group of RF signals, said tuner means (102) selecting a particular RF signal from said group of RF signals in response to a second control signal (103); characterized by control means (104,110,112,114) for generating said first and second control signals (101,103) for causing said RF switch means (100) and said tuner means (102) to select said particular RF signal; means (120,122,125), coupled to said control means (104,110,112,114) , for entering data in response to operation by a user; memory means (116) having a plurality of areas for storing data related to the tuning of preferred ones of said RF signals, each of said areas storing tuning information specific to the RF signals of a respective one of said groups of RF signals received at one of said RF input terminals (A,B,C); wherein in response to said data entered by said user, said control means (104,110,112,114) sequentially retrieves said tuning data from said memory means (116) in one of a linked mode in which said control means (104,110,112,114) automatically retrieves said tuning data from a second one of said areas after having completed the sequential retrieval of said tuning data from said first area, and an unlinked mode in which said control means (104,110,112,114) automatically begins the sequential retrieval of said tuning data from said first area upon completion of said sequential retrieval of said tuning data from said first area; said control means (104,110,112,114) automatically generating said first control signal (101) for selecting the respective one of said RF input terminals which is related to the memory area from which said tuning data is to be retrieved.
Claim 2
Dependent Claim
48 words
The television receiver of claim 1, characterized in that said data entered by said user comprises a command code for causing said control means (104,110,112,114) to change operating modes between said linked mode and said unlinked mode, a CHANNEL UP command code, and a CHANNEL DOWN command code.
Claim 3
Dependent Claim
417 words
A television receiver, comprising: a plurality of radio frequency (RF) signal input terminals (A,B,C), each of which receives a group of RF signals from respective RF signal sources; RF switch means (100) having a plurality of inputs, each of which is connected to a respective one of said RF input terminals (A,B,C), said RF switch means (100) having an output at which is developed one of said groups of RF signals selected from said RF signals at said inputs, said RF input switch (100) having a control input for receiving a first control signal (101) for selecting said selected group of RF signals; tuner means (102) coupled to said RF switch means (100) for receiving said selected group of RF signals, said tuner means (102) selecting a particular RF signal from said group of RF signals in response to a second control signal (103); characterized by control means (104,110,112,114) for generating said first and second control signals (101,103) for causing said RF switch means (100) and said tuner means (102) to select said particular RF signal; means (120,122,125), coupled to said control means (104,110,112,114), for entering data in response to operation by a user; memory means (116) having a plurality of areas for storing data related to the tuning of preferred ones of said RF signals, each of said areas storing tuning information specific to the RF signals of a respective one of said groups of RF signals received at one of said RF input terminals (A,B,C), each of said area including a plurality of memory locations between first and second limits; wherein in response to said data entered by said user,said control means (104,110,112,114) sequentially retrieves said tuning data from said memory means (116) in one of a linked mode in which said control means automatically retrieves said tuning data beginning at said first limit of a second one of said areas after having retrieved said tuning data from said memory location at said second limit of said first area, and an unlinked mode in which said control means (104,110,112,114) automatically begins the sequential retrieval of said tuning data from said memory location at said first limit of said first area upon retrieving said tuning data from said memory location at said second limit of said first area, said control means (104,110,112,114) automatically generating said first control signal (101) for selecting the respective one of said RF input terminals (A,B,C) which is related to the memory area from which said tuning data is to be retrieved
