A method of decoding a coded video bitstream implemented by a video decoder is disclosed. The method includes determining that a coded video sequence (CVS) of the coded video bitstream includes a video coding layer (VCL) network abstraction layer (NAL) unit having a gradual decoding refresh (GDR) network abstraction layer (NAL) unit type (GDR_NUT), the VCL NAL unit having the GDR_NUT containing a GDR picture; initiating decoding of the CVS at the GDR picture; and generating an image according to the CVS as decoded. A corresponding method of encoding is also disclosed.

A method, decoder and server for managing buffers for rate pacing. The decoder includes a memory, a transceiver configured to transmit and receive a signal, and processing circuitry operably connected to the memory and the transceiver. The processing circuitry receives, from the server, a removal rate message indicating a drain rate of a pacing buffer of the decoder. The processing circuitry also provides packets from the pacing buffer to a decoding buffer of the decoder according to the drain rate.

A system for providing 360 video is presented. It includes a video encoder for encoding video data with metadata which includes a manifest. The manifest specifies how to position each video in relation to others during playback. A communication apparatus transmits video data feeds from the video encoder, each video data feed being streamed over one or more uniform resource locators (URLs). The video data feeds are decoded according to the metadata to produce spherical video, the manifest carrying information on how to position video produced from the plurality of video data feeds.

Systems and methods for pre-fetched encoding for application streaming. In some implementations, an indication at a server computer system that a client device has a plurality of representations of template frames may be received. Multiple image frames, provided to a client device by the server computer system, where the processing of each image frame includes determining whether the image frame satisfies a threshold similarity to one of the template frames, may be processed. The operations performed for each image frame that satisfies the threshold similarity to one of the template frames may include, generating a representation of a difference between the image frame and the template frame with which the image frame satisfies the threshold similarity, generating an instruction for rendering the image frame, and providing the instruction to the client device.

An image processing device and an image processing method performing selective image encryption are provided. The image processing method includes compressing an image including a plurality of areas, selectively encrypting some of the plurality of areas, generating encryption information indicating which of the plurality of areas are encrypted, and transmitting an encrypted image and the encryption information.

Methods and apparatuses are provided for receiving content. The method includes receiving a first service, by a receiver of a reception apparatus, the first service providing first content and first metadata associated with the first content. The first content is encoded in one of a plurality of formats decodable by the reception apparatus. Further, the method includes generating, by circuitry of the reception apparatus, first codec mode information based on the first metadata received with the first content.
