Bandwidth efficient hierarchical video coding

An encoding operation is implemented to encode one or more frames, such as game frames, into a game stream. The encoding operation includes decomposing the current frame into a base layer and an enhancement layer. The resulting base layer and enhancement layer are then each encoded to produce an encoded base layer and an encoded enhancement layer. For example, the encoded enhancement layer is truncated according to a comparison of a sum of sizes of the encoded base layer and the encoded enhancement layer to a threshold. In an example embodiment, a multiplexer combines an encoded base layer and a truncated enhancement layer to produce an encoded frame. The encoded frame may then be transmitted to a client device as part of a stream. 实现编码操作以将例如游戏帧的一个或多个帧编码成游戏流。编码操作包括将当前帧分解成基础层和增强层。所得基础层和增强层然后各自经编码以产生经编码基础层和经编码增强层。例如，根据经编码基础层和经编码增强层的大小的总和与阈值的比较来截断经编码增强层。在示例实施例中，复用器组合经编码的基础层和经截断的增强层以产生经编码的帧。然后可以将经编码的帧作为流的一部分传送到客户端设备。
