Abstract
A subscriber terminal includes a receiver for receiving a television signal including video, audio, and data information. A channel of the television signal may be selected for display on the television. A memory stores channel identification information such as channel identifiers. The channel identifiers include at least one display character. A processor establishes a relationship between channel identification information and channel numbers associated with channels of the television signal. An on-screen display control circuit controls the display of character information on the television and has the capability of overlaying the channel number and the channel identification information on the video portion of a selected channel displayed on the television for a predetermined period of time. Program identification information such as program titles may also be displayed. Alternatively or additionally, the channel identification information may be displayed on a display such an LED display of a subscriber terminal.
