A method and system for the UE and RNC to reduce transmission latency and potentially prevent loss of PDUs upon a MAC-hs layer reset. The RNC generates a radio resource control (RRC) message with a MAC-hs reset indication. The MAC reset indication requires the UE to flush buffers for configured HARQ processes, disassemble MAC protocol data units (PDUs) in the reordering buffers, deliver MAC-d PDUs to a MAC-d layer, and configure the MAC-hs to receive new data.

This application provides a TV screenshot method and an associated television (TV). The method includes: upon receiving a screenshot request, acquiring a layer range of On Screen Display (OSD) sub-layers corresponding to windows of every application displayed on an OSD layer; and generating the screenshot image by taking a snap shot of the OSD sub-layers in the layer range. This application can prevent unwanted system notification information image from being captured when a snap shot is taken.

Embodiments of the present application disclose an image generation method and device, which relate to the technical field of image processing. The method comprises: receiving a screenshot instruction; generating a layer corresponding to the screenshot instruction, storing image content in a screen region selected by a user into a storage area corresponding to the generated layer, and displaying, on the generated layer, the image content in the screen region selected by the user, wherein, the storage area corresponding to the generated layer is independent of the storage area corresponding to the layer, which is in an unclosed state, generated according to the previously received screenshot instruction; and after receiving an image generation instruction for at least one layer currently in the unclosed state, generating an output image corresponding to the image generation instruction according to one or more layers corresponding to one or more layer identifiers contained in the image generation instruction, wherein the image generation instruction contains one or more layer identifiers of one or more layers selected by the user. By applying the solution provided by embodiments of the present application, the steps of capturing images many times can be simplified.
