Abstract
Apparatus and method for improving the bandwidth efficiency of delivering electronic program guide (EPG) data to consumer premises equipment (CPE). In one exemplary embodiment, electronic guide data is rendered by devices away from the CPE, shifting the executing data- and bandwidth-heavy operations away from the CPE. In particular, one or more gateways at the user's home bears the processing, memory, bandwidth load to reduce the inefficiency of delivering redundant information to CPE(s) interfacing with the gateway(s). Using guide data it receives from the cloud, the gateway produces and delivers to the CPE one or more “simple views” of the guide data, including a video stream, still image, or simple HTML or other renderable formats. As the end user interacts with the CPE, the user receives a series of the simple views, allowing the rich experience that is typically given by EPG rendered directly by the CPE.
