ABSTRACT:
A method and an arrangement are disclosed for synchronizing on-screen display functions during analog signal reception in a terminal arrangement that is capable of receiving both digital and analog video signals. There are provided means (312, 313) for generating on-screen display objects. Coupled to said means for generating on-screen display objects, there are synchronization pulse generation means (314) for controlling the generation of on-screen display objects. Comparison means (322) are used for comparing synchronization pulses generated by said synchronization pulse generation means (314) with a synchronization signal obtained (320) from an analog video signal. The result of said comparing as a controlling signal is conveyed (323, 324) to a process (314, 325) of generating said synchronization pulses.
