| 20100328528 | TRANSMISSION CAPACITY PROBING USING ADAPTIVE REDUNDANCY ADJUSTMENT - In accordance with an example embodiment of the present invention, there is provided an apparatus configured to instruct a redundancy encoder to increase a level of redundancy of a media stream, an error rate determination to determine an error rate of a communication path conveying the media stream with increased redundancy, a comparator configured to compare a bandwidth used to convey the encoded media stream at the increased redundancy level with a bandwidth for conveying the encoded media stream at a second quality level greater than the first quality level, the apparatus being further configured to provide a switching signal to a media encoder to start encoding the media stream at the second quality level responsive to the used bandwidth being sufficient for conveying the media stream encoded at the second quality level and the determined error rate being less than a predetermined threshold value. | 12-30-2010 |
| 20110115976 | REMOTE TRANSMISSION SYSTEM - A virtual broadband receiver includes a receiving unit to receive a multiplicity of media data streams and an assembly engine to assemble them. The receiving unit receives the data streams from a multiplicity of data connections, wherein each media data stream was transmitted along one of at least one wireless communication network accessible from a remote reporting location to one of the data connections. The assembly engine assembles the data streams into a single media stream forming a live media transmission from the remote reporting location. | 05-19-2011 |
| 20110199535 | MOVING IMAGE DISPLAY - A moving image display includes a data forming unit | 08-18-2011 |
| 20120287338 | VIDEO IMAGE CODED DATA DISPLAY METHOD, DEVICE, AND COMMUNICATIONS SYSTEM - The present invention relates to a displaying method for video image coded data which prevents deterioration of image quality of a video image as much as possible, and conceals, from an observer, deteriorated video quality caused due to a transmission error. The displaying method selects target image frames to be decoded and target image frames to be discarded, by performing error determination ( | 11-15-2012 |

| 20120206645 | DELIVERY SYSTEM, GATEWAY, DELIVERY METHOD, AND PROGRAM - Provided is a delivery system that responds to requests from various terminals and delivers content converted to be viewable/audible by the terminals. The delivery system includes a gateway that requests, if a temporary content accumulation apparatus does not store a moving image stream or moving image file receivable by a content-requesting-terminal, the external delivery server to transmit moving image content specified in a request message, generates a moving image stream or moving image file satisfying reception capability of the content-requesting-terminal, transmits the generated moving image stream or moving image file to the terminal, and stores the generated moving image stream or moving image file in the temporary content accumulation apparatus. | 08-16-2012 |

| 20100194977 | Full Scale Video with Overlaid Graphical User Interface and Scaled Image - The present disclosure relates to displaying full scale images with overlaid similar scaled images and a graphical user device in a display of a client device. The client device receives video streams of the full scale images and scaled images. The video streams are broadcast independent of one another, and a user of the client device may manipulate the format of the images of either or both streams, and/or place the scaled image on any portion of the full scaled image. The graphical user interface is placed so it does not obscure the scaled image. Alternatively a single video stream may be received by the client device. When a single video stream is received, the client device creates two video streams, one stream comprising full scale images and the other stream comprising scaled images. The full scale image is overlaid with the scaled image and the graphical user interface. | 08-05-2010 |
| 20110050990 | SYSTEM AND METHOD FOR EMBEDDING DATA IN VIDEO - Apparatus and method for embedding data in initial content having synchronized video and audio, the method comprising defining at least one content segment in the initial content, and altering the video and audio synchronization in the at least one segment in accordance with the data to be embedded, wherein the altered content segment is viewable on a viewing device and the synchronization alteration is imperceptible to a casual viewer. Related apparatus and methods are also described. | 03-03-2011 |
| 20110069223 | VIDEO/AUDIO DATA OUTPUT DEVICE AND METHOD - A video/audio data output device includes a demultiplexing section, a video decoder that generates video data by decoding the video stream signal, an audio decoder that generates audio data by decoding the audio stream signal, a video output section that outputs the video data in synchronism with the system clock, an audio output section that outputs the audio data in synchronism with the system clock, a video adjusting section, and an audio output adjusting section. The demultiplexing section demultiplexes a video stream signal, an audio stream signal, and a system clock from an input signal, the video adjusting section processes a video frame that has been output from the video output section, and the audio output adjusting section delays the system clock to be supplied to the audio output section, in accordance with a length of time that the video adjusting section takes to process the video frame. | 03-24-2011 |
| 20130155318 | Audio Output Distribution - In some embodiments, a request for an audio stream associated with a video output may be received. Upon receiving the request, the requested audio stream may be encoded for transmission over a network and sent to a user device associated with the request. | 06-20-2013 |
