Method in a digital mobile station, a digital mobile station, application software, and a system for displaying visual information
First Claim
1. A method for use in a digital mobile station (MS) operating in a wireless communication network, which mobile station (MS) comprises at least one or more digital signal processors (DSP) or corresponding processing means to generate a digital transmission signal flow (DTR) for a wireless transmission connection to be used in said communication network, comprising the steps of:
- generating a video signal in said mobile station (MS) by controlling said at least one or more digital signal processors (DSP) or corresponding processing means to generate, instead of the transmission signal flow (DTR), one or more digital video signal flows (DCV, DV) from image material stored in or transmitted into the memory (MEM) of the mobile station (MS).

Abstract
The invention relates to a method in a digital mobile station (MS), which mobile station (MS) for a wireless transmission connection comprises at least one or more digital signal processors (DSP) or corresponding processing means for generating a digital transmission signal flow (DTR). According to the invention, said one or more digital signal processors (DSP) or corresponding processing means are controlled to generate, instead of a digital transmission signal flow (DTR), one or more digital video signal flows (DV, DCV) from image material stored in or transmitted into the memory (MEM) of the mobile station (MS), which one or more digital video signal flows are further led to a digital or analog video output (Vout) of the mobile station (MS). The video output (Vout) can be generated, for example, as an analog composite video signal or a digital video signal according to the IEEE 1394 standard. The invention also relates to a digital mobile station (MS) implementing the method, application software for a mobile station, as well as a system for displaying visual information.

- 28. Application software embodied in a computer radable medium for a digital mobile station (MS), which mobile station (MS) comprises at least one or more digital signal processors (DSP) or corresponding processing means to generate a digital transmission signal flow (DTR) for a wireless transmission connection to be used in the communication network, wherein said application software when loaded in the mobile station (MS) and executed in the mobile station (MS) is arranged to control said at least one or more digital signal processors (DSP) or corresponding processing means to generate, instead of the transmission signal flow (DTR), one or more digital video signal flows (DCV, DV) from image material stored in or transmitted into the memory (MEM) of the mobile station (MS).
- 31. A system for displaying visual information, the system comprising a digital mobile station (MS) and at least one external audiovisual device (AV) coupled to said mobile station (MS) in order to display image material stored in or transmitted into the memory (MEM) of the mobile station (MS), wherein the one or more digital signal processors (DSP) or corresponding processing means comprised in the mobile station (MS) and which are during a wireless transmission connection arranged to generate a digital transmission signal flow (DTR), are instead of said digital transmission signal flow (DTR) controlled to generate one or more digital video signal flows (DCV, DV) from the image material stored in or transmitted into the memory (MEM) of the mobile station (MS), and that the mobile station (MS) further comprises means for conducting said one or more digital video signal flows (DCV,DV) to said at least one external audiovisual device (AV) via an digital or analog video signal (DV,ACV) output (Vout).
