Abstract: Two or more video streams including a high quality video stream and a low quality video stream are simultaneously transmitted to the video receiving device over the wireless network. All of the video streams carry the same video content but with different video quality. The high quality video stream is encoded using an unequal error protection code so that first components (e.g., high frequency components) receive a higher level of error protection than second components (e.g., low frequency components). The video receiving device can select the high quality video stream when channel conditions are favorable. When channel conditions are not good enough to support the high quality video stream, the video receiving device determines whether the first components of the high quality video stream with the greater error protection are usable. If so, the video receiving device combines the first components of the high quality video stream with the low quality video stream.

Abstract: The present invention is directed towards a method and a device for preparing a message in a portable electronic device such as a cellular phone. The device comprises a message type selection unit (14) providing a set of items of message types (20, 22, 24, 26, 28) that can be selected by a user, a first user input unit (32), for allowing message type selection by the user, and a control unit (40) arranged to: provide the set of items of message types (20, 22, 24, 26) that can be selected by a user, detect a message selection by a user via said user input unit (32), change transmission format in dependence of the selections made by the user. In this way for instance a message can be prepared and saved in advance of deciding final message type for transmission.

Abstract: Methods of receiving availability data at a subscriber of a presence service include receiving from a presence server providing the presence service availability information associated with users associated with the subscriber of the presence service. Update information associated with a downloadable content record stored at a device remote from the presence server is received from the presence server. It is determined if the downloadable content record is new to the subscriber of the presence service based on comparing the received update information and current information for the downloadable content record maintained by the subscriber of the presence service. The downloadable content record may be, for example, a podcast.
