    摘要： System and method for learning the optimal channel change instruction recognition speed for an entertainment system. A memory stores information relating to: time increments between channel change signals; pulse width of each individual digit of a channel instruction; and the duration of time between each digit pulse signal. Based on the information stored in memory, a microprocessor constructs and sends channel change commands at a particular speed, progressively increasing the speed. When the speed at which channel change commands are sent exceeds the capability of the television receiver to recognize the channel change command, the microprocessor reduces the speed, as a function of the information stored in memory, until the television receiver can recognize the channel change command. The microprocessor stores in memory the fastest speed at which the television receiver can recognize the channel change command. Thereafter, the microprocessor uses the optimal speed to deliver channel change commands.

    摘要： Apparatus, systems and methods are provided for learning the optimal channel change instruction recognition speed for the components of a particular entertainment system. A memory provides storage for information relating to: time increments between channel change signals; pulse width of each individual digit of a channel instruction; and the duration of time between each digit pulse signal. As a function of the information stored in memory, a microprocessor constructs and sends channel change commands at a particular speed, progressively increasing the speed. A means is provided for monitoring the television receiver and for detecting whether the channel change command resulted in the change of the programming channel received by the television receiver. When the speed at which channel change commands are sent exceeds the capability of the television receiver to recognize the channel change command, the microprocessor reduces the speed, as a function of the information stored in memory, until the television receiver can recognize the channel change command. The microprocessor stores in memory the fastest speed at which the television receiver can recognize the channel change command. Thereafter, the microprocessor uses the optimal speed to deliver channel change commands.

    摘要： A channel map in an electronic television program guide system that includes channel numbers and alphanumeric channel labels is updated. The tuner in the system is tuned to a channel number of a television channel that is included in the channel map. Data is extracted from the television signal that includes an alphanumeric label for the tuned television channel. The channel mapis revised according to the alphanumeric label for the tuned television channel if the alphanumeric label in the extracted data for the tuned television channel does not correspond with the alphanumeric channel label stored in the channel map for the tuned television channel.
