摘要： Various aspects of the present disclosure relate to video codec aware RAN configuration and unequal error protection coding. An apparatus includes a memory and a processor coupled to the memory that is configured to cause the apparatus to detect a video coded traffic stream and a video codec profile for encoding the video coded traffic stream, determine an awareness of PDU sets of the video coded traffic stream, align, based on at least the awareness of PDU sets, each PDU set of the video coded traffic stream to PHY transport elements and channel coding element partitions for a video coded traffic aware PHY transport, determine a channel coding rate allocation of the channel coding element partitions based on the video coded traffic aware PHY transport, and apply a FEC coding to the channel coding element partitions based in part on the channel coding rate allocation.

摘要： A reference-order AL-FEC system for recovering network video data packet loss during real-time video communication includes a packetizer, a reference-order AL-FEC encoder, a reference-order AL-FEC decoder and a depacketizer. The packetizer constructs source symbols from source packets of a current frame. The encoder generates a repair symbol from the source symbols of the current frame and other reference frames based on the reference-order, not time-order, between the frames within an encoding window. The encoder also generates a repair packet based on the repair symbol. The decoder recovers a lost source symbol based on the source symbols of the frames of the encoding window and the repair symbol by decoding the repair packet. The decoding is achieved by solving a linear system of the repair symbol.

摘要： Decoder retrieval timing information, ROI information and tile identification information are conveyed within a video data stream at a level which allows for an easy access by network entities such as MANEs or decoder. In order to reach such a level, information of such types are conveyed within a video data stream by way of packets interspersed into packets of access units of a video data stream. In accordance with an embodiment, the interspersed packets are of a removable packet type, i.e. the removal of these interspersed packets maintains the decoder's ability to completely recover the video content conveyed via the video data stream.

摘要： Optimal resilience to errors in packetized streaming 3-D wireframe animation is achieved by partitioning the stream into layers and applying unequal error correction coding to each layer independently to maintain the same overall bitrate. The unequal error protection scheme for each of the layers combined with error concealment at the receiver achieves graceful degradation of streamed animation at higher packet loss rates than approaches that do not account for subjective parameters such as visual smoothness.

摘要： Systems and techniques are disclosed for dynamically and automatically selecting an appropriate compression technique and/or compression parameters for digital images in order to reduce or prevent loss of significant information that may negatively impact the utility or usefulness of the digital images. For example, based on various image characteristics associated with a digital image, the system may dynamically compress the image using particular compression techniques and/or by adjusting compression parameters, to maintain significant information of the image. The system may select compression techniques and/or compression parameters based on one or more compression rules, which may be associated with image characteristics, patient characteristics, medical history, etc. Further, the system may, based on the one or more compression rules, compress the image to a maximum degree of compression while maintaining the significant information of the image.

摘要： The present invention concerns a method of encoding a media bitstream of a media content. The media bitstream comprises a payload portion for the media content, and an overhead portion, different from the payload portion. The method comprises the steps of: modifying a part of the payload portion of the media bitstream, the modified part representing a region of the media content; and inserting the said part, as unmodified, into the overhead portion of the modified media bitstream for later reconstruction of the unmodified payload portion, such that the modified part in the media bitstream can be decoded without decoding the part as unmodified from the overhead portion. The invention also relates to a method of decoding, to an encoder and to a decoder.

摘要： A cross-layer encoder for providing UEP encoding of video data can be configured to provide UEP encoding of video data at an application layer of a transmission channel by receiving video packets having first and second priority levels, applying first and second coding schemes to video packets having first and second priority levels, respectively, and transmitting video frames having first and second priority levels. The cross-layer encoder can be configured to provide UEP encoding of video data at a physical layer of the transmission channel by receiving encoded video frames having first and second priority levels, applying third and fourth coding schemes to video frames having first and second priority levels, respectively, and transmitting cross-layer encoded video frames having first and second priority levels. The first through fourth coding schemes can generate different percentages of the total coding overhead based on first and second priority levels, respectively.
