Apparatuses and methods may provide for technology that uses a wireless display docking over an infrastructure network by receiving, via a WiFi link, information associate with an infrastructure discovery of a receiver, using the information to discover the receiver via an infrastructure network i link, forming a connection with the receiver via the infrastructure network link, and streaming content to the receiver via the connection. In addition, receiver technology may emit a beacon signal via a WiFi link, form a connection with a client device via an infrastructure network link, and receive streamed content from the client device via the infrastructure network link.

Using wireless display docking technology over infrastructure networks

According to an embodiment of the present invention, a method is presented for controlling a video image compression system. In this method a video frame of raw video image data is compressed using a processor. Then it is determined whether the processor is limited in its ability to compress video image data. Then, a target frame rate is adjusted based on a current amount of time taken to compress said video frame of raw video image data.

Facilitating a distributed multipoint conference using, for example, the ITU-T H.323 protocol may involve establishing a connection (e.g., that supports a unicast stream) between multiple endpoints, including at least a requesting endpoint and one or more other participating endpoints, and initiating a connection from the requesting endpoint to at least a third endpoint. The requesting endpoint identifies to the third endpoint the one or more other participating endpoints. A connection is established between the third endpoint and the one or more other participating endpoints identified by the requesting endpoint. The third endpoint identifies the requesting endpoint to the one or more other participating endpoints. At each of the endpoints, unicast streams received from each of the other participating endpoints may be mixed to form a logical multipoint conference.

A method and apparatus select the wire video size and capture video size of a video telephony product depending upon the desired remote video size. A target frame rate is taken into account when choosing the wire video size and capture video size. Wire video size is chosen as close to the desired remote video size as possible. To provide high quality, the video capture frame rate and capture video sizes are maintained above a predetermined level.

In a video image compression and transmission system, quantization parameters for a block transform based video compression algorithm can be controlled by a quantizer selector so as to control compressed video frame size. The selection of the appropriate quantization parameter for the nth macroblock of a current frame is based on the cumulative number of compressed bits appearing in the first n-1 macroblocks of a current frame and a previous frame. By controlling the quantization parameter is such a manner, the overall system reacts more quickly to changes in complexity in the video sequence and allocates bits more accurately to different parts of the video frame according to a past history of bit allocation. To efficiently utilize the bandwidth of a transmission medium (such as POTS), a bit count of the contents of the transmit buffer is sent to a buffer regulator in a video controller where it is compared to a low water mark threshold. If the bit count falls below the threshold, an uncompressed video frame is scheduled for compression by a video compressor. By using the low water mark threshold, latency in the overall system is reduced and an efficient use of transmission medium bandwidth is achieved.

An apparatus is programmed with a video service for facilitating video communication with another remote apparatus, in accordance with a video communication protocol. The video service includes a still image function with logic for providing a plurality of progressive scans of one or more still images to the remote apparatus, in accordance with a still image communication protocol defined within the video communication protocol. In one embodiment, the still image function includes logic for instructing a local video capture driver to switch to a format of the still image function's choice for capturing video image frames, holding constant video image input to a video codec to generate the plurality of progressive scans of the still images, and implementing the still image communication protocol.

A method for creating a video connection between a video source for transmitting frames of video data and a video sink for receiving the frames. The video source may be a file, a camera, a computer network, and a telephony interface. The video sink may be a file, a visual display device, a computer network, and a telephony interface. The video source has a recycle framehandler function for recycling used buffers and the video sink has a process framehandler function for processing received frames. A video stream object is created having data members that include a reference to the video sink and a reference to the video source, as well as several member functions. The member functions are used to query the video sink to obtain a reference to the process framehandler function and to then provide the reference to the video source. The member functions are also used to query the video source to obtain a reference to the recycle framehandler function, which is then provided to the video sink. The reference to the process framehandler function is stored as a data member of a first framehandler object to be used by the video source, and the reference to the recycle framehandler function is stored as a data member of a second framehandler object to be used by the video sink. The video source may then directly invoke the process framehandler function and the video sink may directly invoke the recycle framehandler function.
