  • Publication number: 20220394064
    Abstract: An apparatus includes a transceiver to support a media flow involving a user equipment and an Internet Protocol (IP) Multimedia Subsystem (IMS) network that are connected via a media path that traverses a first realm associated with the user equipment, a second realm, and a third realm associated with the IMS network. In some cases, the apparatus includes a processor to establish a first context to perform interworking between the first realm and the second realm in response to an offer message from the user equipment. The processor later de-allocates the first context in response to receiving an answer message indicating that a second context performs interworking between the first realm and the third realm. In other cases, the processor bypasses allocation of a context to perform interworking between the second realm and the third realm in response to an indication that the media flow is anchored on an incoming side.

  • Publication number: 20220353497
    Abstract: This application provides a video picture decoding and encoding method and a video picture decoding and encoding apparatus. When it is determined that a merge or skip mode is used, if it is determined through decoding that a merge mode with motion vector difference (MMVD) indicator is true, a triangle prediction unit (PU) indicator may not be coded. The triangle PU indicator is coded when it is determined through decoding that the MMVD indicator is false. This reduces a quantity of used coding resources, and can reduce bit overheads of a bitstream.
