  • Patent number: 11368694
    Abstract: A quantized transform coefficient matrix is partitioned into a sequence of partition portions. The coefficients of the matrix are grouped into the sequence of partition portions based on a hardware implemented scan order. Each partition portion is processed in an order of the sequence in a first pass. For each partition portion, a group of coefficients in the partition portion is determined. For each partition portion, a first data rate estimation for the quantized transform coefficient matrix is updated based on at least some coefficients of the group of coefficients in the partition portion and a maximum end-of-block. For each partition portion, an end-of-block estimation of the quantized transform coefficient matrix is updated based on at least some coefficients of the group of coefficients in the partition portion. A first resulting data rate estimation and a true end-of-block of the quantized transform coefficient matrix are determined after the first pass.

    Abstract: A configuration helper system (CHS) is described that simplifies the task of generating configuration information for a customer premises equipment (CPE) in a customer's on-premise network to enable the CPE to communicate with the customer's cloud network over a particular communication channel. The CHS is configured to generate configuration information that is customized for the particular CPE and communication channel. Given information about the CPE and the communication channel, the CHS automatically identifies a particular set of configuration parameters to be included in the customized configuration information and determines values for the set of parameters, where some of the values may be provided by the customer. A particular CPE-specific format is determined for the configuration information.
