Abstract: Seamlessly transferring a communication. At least one communication is established between a first device and a second device. The at least one communication is transferred from the second device to a third device without interrupting the at least one communication and without disconnecting the at least one communication from the first device.

Abstract: Aspects of the invention are directed to a telephony system that is adapted to receive, route, process, and deliver communications data using a cost-effective, user-friendly operations platform and a broadband communication network. For example, the system includes a computer server arrangement and a plurality of endpoint devices communicatively coupled to one or more communication channels comprising an Internet protocol (IP) network. Packet-based (VoIP) calls are transmitted over an IP network, and translated to standard PSTN call signals when necessary. The broadband telephony system of the present invention utilizes each user's own IP network endpoint device as not only each user's local gateway onto the IP network, but also as a remote gateway for bridging other user's calls from the IP network to a local PSTN network in order to reach non-users.

Abstract: Systems and methods for enabling the use of multi-touch applications on touch screens configured to receive only a single touch input at a time are disclosed. Systems and methods for dual heap memory allocation are also disclosed. Systems and methods for meta-layer rendering for mark-up code on mobile devices and storage of the meta-layers is also disclosed. Combinations of the above systems and methods are further disclosed.

Abstract: According to one aspect of the disclosure, the present invention provides methods and arrangements for the removal or reduction of divergence artifacts between a transmitting codec and a receiving codec. One of a number of implementations includes using a deblocking filter in an inverse transformer loop and selectively disabling the filter upon certain conditions.

Abstract: A still image is progressively transmitted over a communications channel by computing, encoding, and outputting for transmission difference information representing the difference between the still image and a lower quality representation of the still image that has been received by a remote location. This process is repeated, with additional difference information being generated to supplement the image received at the remote location, such that the quality of the image at the remote location improves over time. The difference information may be encoded in a format compatible with existing video compression standards and processed by a receiving terminal regardless of the presence of still mode capability.

Abstract: A still image is progressively transmitted over a communications channel by computing, encoding, and outputting for transmission difference information representing the difference between the still image and a previously-transmitted image that has been stored at a remote location. This process is repeated, with additional difference information being generated to supplement the image received at the remote location, such that the quality of the image at the remote location improves over time. The difference information may be encoded in a format compatible with existing video compression standards and processed by a receiving terminal regardless of the presence of still mode capability.

Abstract: In a method for encoding successive frames of a digital motion video signal in the form of compressed digital data including an intraframe coded signal and a plurality of interframe coded signals, a first frame of the digital motion video signal is encoded to form one of an intraframe coded signal and an interframe coded signal to produce a compressed digital signal; the compressed digital signal is decoded to form a decoded signal; a plurality of predicted video signal frames are produced representing a second frame of the digital motion video signal other than the first frame, at least one of the plurality of predicted video signal frames being produced with the use of the decoded signal and a motion vector representing motion between frames of the digital motion video signal; the plurality of predicted video signal frames are compared with the second frame of the digital motion video signal for producing a plurality of difference data each corresponding with a respective one of the plurality of predicted v

Abstract: A method of encoding a video signal into highly efficiently encoded data comprises the steps of: digitizing and blocking the video signal; performing a discrete cosine or Fourier transform on the blocked data; controlling the amount of data in each block to be substantially constant according to an amount of encoded data awaiting transmission; calculating a threshold amplitude; and selecting data larger in amplitude than the threshold amplitude as encoded data for transmission.
