    Abstract: Two or more video streams including a high quality video stream and a low quality video stream are simultaneously transmitted to the video receiving device over the wireless network. All of the video streams carry the same video content but with different video quality. The high quality video stream is encoded using an unequal error protection code so that first components (e.g., high frequency components) receive a higher level of error protection than second components (e.g., low frequency components). The video receiving device can select the high quality video stream when channel conditions are favorable. When channel conditions are not good enough to support the high quality video stream, the video receiving device determines whether the first components of the high quality video stream with the greater error protection are usable. If so, the video receiving device combines the first components of the high quality video stream with the low quality video stream. Otherwise, the video receiving device outputs the low quality video stream.

    Abstract: A media container file (30) is generated by organizing encoded video data representative of multiple camera views (22-28) of a video content as one or more video tracks (32) in the media container file (30). A view arrangement representation (34) indicative of a predefined deployment and position relationships of camera views (22-28) is selected among multiple different such predefined view arrangement representations. The view identifiers (36) of the multiple camera views (22-28) are included in the selected view arrangement representation (34). The view arrangement representation (34) with the included view identifiers (36) is organized in the media container file (30) relative the at least one video track (32).

    Abstract: A system and method are described below for encoding interactive low-latency video using interframe coding. For example, one embodiment of a computer-implemented method for performing video compression comprises: logically subdividing each of a sequence of images into a plurality of tiles, each of the tiles having a defined position within each of the sequence of images, the defined position remaining the same between successive images; detecting motion or high scene complexity within the sequence of images occurring at each of the positions of each of the tiles; and encoding each tile within each image of the sequence of images using a specified number of bits, the number of bits selected based on the detected amount of motion at the position of each tile across the sequence of images.

    Abstract: The invention teaches a media container file (1) comprising media data organized into media source blocks (20; 22; 24). The media source blocks (20; 22; 24) are partitioned into source symbols that can be processed by a forward error correction (FEC) algorithm for generation of FEC redundancy data (70). Information (30; 32; 34) of this source block partitioning is included in the file (1) in addition to the source blocks (20; 22; 24). The container file (1) also comprises meta data (40) providing an association between the media source blocks (20; 22; 24) and the partitioning information (30; 32; 34). The container file (1) can be employed by a media server (200) in a media session for compiling media data packets to be transmitted to requesting clients (400; 410; 420) without the need of extensive data processing before calculating FEC data.

    Abstract: Priority information may be used to distinguish between different types of video data, such as different video packets or video frames. The different types of video data may be included in the same temporal level and/or different temporal levels in a hierarchical structure. A different priority level may be determined for different types of video data at the encoder and may be indicated to other processing modules at the encoder, or to the decoder, or other network entities such as a router or a gateway. The priority level may be indicated in a header of a video packet or signaling protocol. The priority level may be determined explicitly or implicitly. The priority level may be indicated relative to another priority or using a priority identifier that indicates the priority level.
