Abstract
Techniques are disclosed for capturing, transcoding, and caching off-air programming at a location local to the consumer. According to certain embodiments, a device is provided that receives off-air (e.g., broadcast) and/or cable (e.g., ClearQAM) programming via one or more antennas and caches the programming in various streams having various bit rates for later viewing using, for example, Adaptive Bit Rate (ABR) streaming. Such a device can be incorporated in a larger system that can stream content via a data communication network (e.g., the Internet) and the device in a seamless manner. The device also can be controlled by a remote system via the data communication network, and further can be configured to stream content to a remote device via the data communication network.
