摘要： Techniques are provided for transmitting high quality multimedia data from a device for live and on-demand viewing. The device adjusts the quality of a single multimedia data stream based on one or more factors, such as the available bandwidth of a wireless link with a server, whether there are any “live” subscribers of the multimedia data stream, whether any “live” subscribers are interacting with the device, and a change in the privacy settings of the user of the device. Any data that was removed from the multimedia data stream before it was transmitted to a server is subsequently sent to the server. The server generates multiple versions of the multimedia data stream that vary in terms of quality. The server selects which version of the multimedia data stream to transmit to a subscriber of the multimedia data stream based on one or more criteria.

摘要： An encoder stage, and corresponding encoded bitstream and decoder. The encoder stage comprises: a variable length encoder for encoding an input signal; and a counter configured to dynamically detect an observed frequency at which different symbols are found to occur within each of a plurality of predetermined portions of the input signal, prior to the symbols of each respective portion being encoded by the variable length encoder. The variable length encoder is configured to encode the symbols of each portion using variable length coding performed in dependence on the observed frequencies detected within the respective portion of the input signal, to generate an encoded bitstream comprising the encoded symbols along with an additional element indicating information regarding the observed frequencies detected for each portion, and to output the encoded bitstream to at least one of a storage medium and a transmission medium for supply to a decoder.

摘要： This document describes techniques and apparatuses for limiting processing resources incurred due to refreshing a user interface. In various embodiments, an event is received, and it is determined whether a delay time period has elapsed. A length of the delay time period is based on a timing of receipt of one or more previous events. If the delay time period has not elapsed, refreshing of the user interface is postponed. When the delay time period elapses, the user interface is refreshed to display an indication of the event.

摘要： Various embodiments process updates of an image transmitted between a first terminal and second terminal for screen sharing, wherein updates to the image at the first terminal are also displayed at the second terminal. The image is divided into an array of contiguous sub-tiles, each sub-tile comprising more than one picture element of the image. When a plurality of sub-tiles of the image have changed at the first terminal, at least one of said changed sub-tiles and at least one contiguous sub-tile are selected to form a tile. The tile is encoded for transmission to the second terminal, and includes sub-tile data identifying which sub-tiles are included in the tile to enable updating the image at the second terminal in accordance with the changes to said changed sub-tiles. The configuration of the tile is flexible such that the number of contiguous sub-tiles encoded in the tile can be varied.
