    Abstract: A method of outputting image data at a display device having a plurality of decoders is disclosed. The method includes receiving image data of a source frame from a host device, the image data comprising a plurality of streams of blocks, each block comprising encoded image data for a portion of the input frame. A set of first blocks associated with a first stream of blocks are selected and passed to a first decoder. A set of second blocks associated with a second stream of blocks are selected and passed to a second decoder. The first decoder decodes the first blocks of the first stream and outputs decoded image data for the first blocks to a shared memory to form a first part of a decoded frame. The second decoder decodes the second blocks of the second stream and outputs the decoded image data for the second blocks to the shared memory to form a second part of the decoded frame. The decoded frame is then output to a display.

    Abstract: This invention is generally related to methods and devices for server administration. A terminal-to-mobile-device system (100) comprising a terminal controlled by a mobile device (160), the system (100) further comprising: a computing device (110) comprising a computing device processor (115), a random access memory (120), a read-only memory (125), a video adapter (130), computing device display means (135) and computing device data exchange means (140) and implementing functions of the terminal. The mobile device (160) comprises a mobile device processor (165), a decoding module (170), mobile device display means (175) and control means (180) configured to be manipulated by a user (105), the mobile device (160) being configured to exchange data with the computing device data exchange means (140). The computing device (110) is configured to transfer video data from the video adapter (130) to the computing device data exchange means (140) after the video adapter (130) sends a signal to the computing device processor (115) informing it about readiness of the video data and before sending the video data from video adapter (130) to the computing device display means (135). The computing device data exchange means (140) are configured to code the video data by using a coding parameter characterized by a number of frames to which the processed frame refers, and to transfer the coded video data to the mobile device (160). The mobile device (160) is configured to decode, by means of the decoding module (170), the video data obtained from the computing device (110), and to display, by means of the mobile device display means (175), the decoded video data in a virtual reality format. The mobile device (160) is configured to generate control signals based on signals from the control means (180) and to send the generated control signals to the computing device (110). The decoding module (170) is configured to use a minimum possible number of buffers and to decode without synchronization with the frame frequency; the decoding module (170) further being configured to use modes designed for a larger resolution or a larger frame frequency than that of an actual video stream. A method for remote control of a terminal by a user using the proposed system is also proposed.

    Abstract: In various implementations, methods, apparatuses, and computer-readable media are described for providing an indication that a file includes corrupted video frames. For example, the file can include an indicator to indicate one or more video frames associated with a particular playing timestamp and playing duration are corrupted. The indicator can also be configured as an unified indicator associated with both corrupted video frames and missing video frames. In some implementation, the signaling of presence of corrupted video frames can come in the form of omission of those corrupted video frames from the media file. In various implementations, modifications and/or additions to one or more existing media streaming schemes can also indicate to a receiver device that a media segment contains missing (or otherwise non-decodable) frames, prior to the receiver device requesting the media segment.
