The present invention provides a method and apparatus for automatically setting the time in a peripheral device (170) in a television system (10). In the preferred embodiment, a datastream (300) with packets of data (310-313) is broadcast to the peripheral device (170). A time value (400) within the received datastream (300) is used to set the time within the peripheral device (170). The data within the received datastream (300) also contains a cyclic redundancy check (410) which is used to determine when an error is present in the received data packet (310). The time is set in the peripheral device (170) only when the cyclic redundancy check has found no errors in the data packet (310). When needed, additional values within the received packet (310) can later be used to correct the time which has been set in the peripheral device (170).

[ What is claimed is:] [1.] A method for automatically setting the time in a television system with television schedule data, comprising the steps of:broadcasting a datastream with at least one data packet to a peripheral device, said datastream containing said television schedule data, said peripheral device being within said television system, said data packet including a cyclic redundancy check and a time value, said cyclic redundancy check capable of indicating errors in said data packet;searching for a VBI line containing said datastream;identifying a first byte in said data packet with a processor after said VBI line containing said datastream is found, said processor being located in said peripheral device;utilizing said cyclic redundancy check to determine if said data packet contains an error, said utilizing of said cyclic redundancy check occurring after said first byte is identified;storing said time value in a memory when said data packet is free of errors, said memory being located in said peripheral device;setting a time in said peripheral device with said processor, said processor using said time value stored in said memory to set said time;storing a portion of said television schedule data in said memory; andgenerating a television schedule guide with said television schedule data, said time being used in said generation of said television schedule guide.
