摘要： A method of partitioning a video coding block for JVET, comprising representing a JVET coding tree unit as a root node in a quadtree plus binary tree (QTBT) structure that can have a quadtree branching from the root node and binary trees branching from each of the quadtree's leaf nodes using asymmetric binary partitioning to split a coding unit represented by a quadtree leaf node into two child coding units of unequal size, representing the two child coding units as leaf nodes in a binary tree branching from the quadtree leaf node and coding the child coding units represented by leaf nodes of the binary tree with JVET, wherein further partitioning of child coding units split from quadtree leaf nodes via asymmetric binary partitioning is disallowed.

摘要： A user environment is controlled and altered based on one or more user conditions received from a biometric tracking services associated with a biometric device of a user. A user can set up a user profile that includes one or more user preferences including a biometric parameter, an asset parameter, a biometric service parameter and/or a location parameter. Based on the user preferences a user device and/or an access point device can control the user environment by altering one or more assets of one or more network devices specified by any one or more user preferences. The asset state of an asset can be altered based on one or more user conditions associated with a biometric parameter such that the user environment is automatically altered based on monitoring the one or more user conditions so as to provide the user an enhanced user environment experience.

摘要： A method of decoding a bitstream comprising decoding the bitstream into color values and metadata items indicating information about adaptive post-processing operations performed by a decoder, performing high dynamic range (HDR) adaptation operations on the color values based on the metadata items, and performing fixed post-processing operations to reconstruct an HDR video from the color values, wherein the HIDR adaptation operations convert color values into a format expected by the fixed post-processing operations.

摘要： A method of encoding a digital video data applies adaptive pre-processing to data representing high dynamic range (HDR) and/or wide color gamut (WCG) image data prior to encoding and complementary post-processing to the data after decoding in order to allow at least partial reproduction of the HDR and/or WCG data. The example methods apply one or more color space conversions, and a perceptual transfer functions to the data prior to quantization. The example methods apply inverse perceptual transfer functions and inverse color space conversions after decoding to recover the HDR and/or WCG data. The transfer functions are adaptive so that different transfer functions may be applied to video data sets including different groups of frames, frames or processing windows in a single frame. Information on the data set and information on the applied transfer function is passed as metadata from the encoder to the decoder.

摘要： A network device receives an IPv4-in-IPv6 packet. An IPV6 header is removed. A first DSCP value in a TC field and a second DSCP value in a ToS field is stored in a database. The IPv4 packet is forwarded upstream and a return IPv4 packet is received. The returned IPv4 packet is encapsulated to form an IPV6 packet. The first DSCP value and the second DSCP value are retrieved from the database. Based on the at least one policy, the second DSCP value is inserted into an IPV4 ToS field and into an IPV6 TC field, the retrieved second DSCP value is inserted into the IPV4 ToS field and the first DSCP value is inserted into the IPV6 TC field, or the first DSCP value is inserted into the IPV6 TC field and into the IPV4 ToS field. The network device then forwards the IPv6 packet downstream.

wherein L is a luminance value, c1, c2, c3, and m1 are parameters with fixed values, and m2 is a parameter with a variable value, adapting the perceptual quantizer function by adjusting the value of the m2 parameter based on different luminance value ranges found within a coding level of the digital video, encoding the digital video into a bitstream using, in part, the perceptual quantizer function, transmitting the bitstream to a decoder, and transmitting the value of the m2 parameter to the decoder for each luminance value range in the coding level.-

摘要： A system and method enabling the concurrent provision of multiple multi-user band transmissions, each via a single cable, to a media gateway appliance, thereby providing the media gateway appliance with an increased array of user bands for the provision of program content. The multiple multi-user band transmissions can originate from a single multi-output single-cable interface, or from multiple single-output single-cable interface. This enables the switching fabric and internal tuners of a given media gateway appliance to select any one of the provided user bands and demodulate program content therefrom.
