Abstract: This invention describes an adaptation system providing terminal-specific uniform resource locators (URLs) of downloadable software allowing a receiving terminal to render originally unsupported components of multimedia messages. The URLs are provided to the receiving terminal by a multimedia messaging service center (MMSC) which identifies the URLs from its database using information on the receiving terminal capabilities (i.e. based on terminal model and software release) and possibly multipurpose internet mail extension (MIME) types of originally unsupported components in multimedia messages.

Abstract: Apparatus, and an associated method, for reducing the resolution of a digital image, such as a JPEG image. The digital image is pre-scaled by a pre-scaling factor that is selected such that a matrix multiplication is performed upon the digital image once pre-scaled, to reduce the resolution of the image. The matrix multiplication utilizes a multiplier that exhibits symmetry, thereby to reduce the number of calculations required to reduce the resolution of the image. Resolution reduction is performed, for instance, prior to communicating the digital image to a mobile station operable in a mobile communication system.

Abstract: A system and method for conveying content-specific characteristics related to terminal capabilities and user preferences, and adapting content for particular terminals in response to the conveyed information. A content type or other message characteristic that is recognizable by the terminal is identified, as are operational confines of the terminal by which the content type is to comply. The content type is associated with the operational confines of the terminal. The content type and associated operational confines are provided to the network server for use by the network server in delivering messages to the terminal as dictated by the operational confines.

Abstract: A system of Session Initiation Protocol (SIP) terminals capable of processing SIP messages and SIP servers that perform selected functions at the request of the SIP terminals, includes a SIP server (12) for pre-registering capabilities and user preferences of a registering terminal (15) after resolution by a Capability Negotiation Manager (16), and for subsequently receiving an incoming SIP message from a sending terminal (19) indicating a message intended for the pre-registered terminal, and adaptation means (20) for adapting the incoming message to meet the capabilities and user preferences of the pre-registered terminal for transmission by the SIP server to the pre-registered terminal.

Abstract: A method and apparatus are provided for measuring a bit rate between a client and a server. In an embodiment of the invention, a number of bits included only within one or more transaction units are measured over a time period. The time period is a sum of time durations of each of the transaction units. In an embodiment of the invention, bit rate measurements are performed on a server and in another embodiment of the invention bit rate measurements are performed on a client. Embodiments of the invention include adapting, by the server, of content to be sent to the client based on the bit rate measurements. Embodiments of the invention further include reporting the measured bit rate to the server when the bit rate measurements are performed on the client. Other aspects of the invention include sending an indication of the measured bit rate and a desired bit rate to the server when bit rate measurements are performed in the client.

Abstract: The invention relates to a method for providing a terminal MS2 of a communications system with coded still image signals. In order to enable a further content adaptation for multimedia messages, it is proposed that the method comprises receiving coded video signals at a network element of said communications system, converting at least a part of said received coded video signals in said network element to coded still image signals, and delivering said coded still image signals to a terminal MS2 of said communication system. The computation required for said conversion can be minimized by exploiting the commonalities of video and still images compression methods that are based on the Discrete Cosine Transform scheme. Thus it is rendered possible to provide excerpts of transmitted video clips also to terminals not capable of handling at least this particular video clip. The invention equally relates to a corresponding communications system, network element and module for a network element.

Abstract: A method and apparatus is provided for transcoding content communicated in a network. The method features the step of transcoding the content based on permissible transcoding operations authorized by a content creator. The permissible transcoding operations include any transformation, alteration or manipulation of the content. The permissible transcoding operations include: a resolution reduction for reducing a resulting resolution of the content; an aspect ratio modification for specifying a maximum deformation that can be applied to the content when modifying its resolution; a color and bits per pixel modification for specifying if an image can be converted to gray scale or not, and minimum bits per pixel (bpp) or number of colors (or levels) that can be used; cropping for specifying a region of an original picture that must be preserved; and a quality reduction for allowing the content to be further modified by adding some distortions to an image. The content may be images, graphics, video or audio.
