Resources for encoding video signals

Abstract

An apparatus for encoding video data, the apparatus comprising a compliance module configured to relate resource requirements associated with encoding video data using a standard encoding mode to form at least a portion of an encoded frame to an acceptable resource level comparing; and an encoder configured to, in response to determining that resource requirements will exceed the acceptable resource level, form the at least a portion of the encoded frame by encoding some of the video data using a standard encoding mode, and utilize A type of data to fill a remainder of the at least a portion of the encoded frame, wherein the type of data is associated with lower resource usage than data generated using a standard encoding mode.

Description

Background technique [0001] In modern communication systems video signals may be sent from one terminal to another via a medium such as a wired and / or wireless network, often a packet-based network such as the Internet. Typically, frames of video are encoded by an encoder at the transmitting terminal to compress them for transmission over the network. Encoding for a given frame may include intra-coding, where blocks are encoded relative to other blocks in the same frame. In this case, the target block is coded as the difference (the residual) between the target block and the neighboring block. Alternatively, encoding for some frames may include inter-coding, where blocks in the target frame are encoded, typically based on motion prediction, relative to their counterparts in previous frames. In this case, the target block is coded in terms of a motion vector identifying the difference between the target block and its counterpart from which it will be predicted (residual) The...

Problems solved by technology

This can cause problems for sender and receiver buffers (e.g. for hardware decoders) if the number of packets is too large

Very many packets can also take a long time to decode
