Claims16
A customer premise equipment (CPE) device for connecting to a digital network, the CPE device comprising:
- a user input device for transmitting a request to a digital subscriber line access multiplexer (DSLAM) that initiates a selection in the DLSAM of at least one closed caption (CC) signal from among a plurality of CC signals responsive to receiving a user input specifying one or more channels for which closed caption (CC) information is sought, the CC signal corresponding to the CC information;
- and
- a decoder for receiving the CC information for the one or more channels specified by the user input, and for overlaying the CC information for a particular one or the one or more channels on programming content that is to be displayed for another one of the one or more channels.
A method for receiving closed caption (CC) information in a customer premise equipment (CPE) device for connecting to a digital network, the method comprising the steps of:
- transmitting a request to a digital subscriber line access multiplexer (DSLAM) that initiates a selection in the DSLAM of at least one closed caption (CC) signal from among a plurality of CC signals responsive to a user input from the CPE specifying one or more channels for which closed caption (CC) information is sought;
- receiving the CC information for the one or more channels specified by the user input from the DSLAM;
- and
