摘要： A switched broadcast service and a network personal video recorder (NPVR) service are provided synergistically in a cable TV system having limited resources. For example, in providing the switched broadcast service, a resource manager allocates network bandwidth for broadcast of materials from selected program channels on an as needed basis. Such allocation is conducive to an effective provision of the NPVR service which requires dedicated bandwidth for transmitting recorded broadcast program material in a headend to each set-top terminal requesting the NPVR service. Thus, unlike the switched broadcast service where a program stream containing program material is shared by one or more set-top terminals, the NPVR service provides a dedicated program stream to each set-top terminal so that a user at the terminal may manipulate (e.g., rewind, pause and/or fast-forward) a presentation of program material at will.

摘要： In accordance with aspects of the present invention, a technique is implemented to effectively receive streaming multimedia content in digital form, parse and segment the received transport stream and process the segmented content. Such treatment of received programming content provides for efficient storage of such programming content, and effectively provides for access to such content by administrators of a broadband system as well as users of such systems. In accordance with the invention, a technique enables, among other things: the creation of reference frames for, e.g., effective segmentation of programming content; encapsulation of programming content data as a UDP/IP datagram; associating programming content with provider and dedicated resource attributes; monitoring staging processor activity; effectively segmenting programming content that is scrambled; developing a unicast and multicast; compensating for missing or delayed programming content; and propagating video servers of varying manufacturers.

摘要： Apparatus and methods for premises gateway functions that integrate or unify functions typically distributed across multiple devices within a content-based network. In one embodiment, the out-of-band (OOB) signaling functionality normally provided in each of a set-top-box (STB) and digital video recorder (DVR) are unified into a common OOB (e.g., DOCSIS) capable premises gateway device, thereby obviating OOB tuners and related components from each device. In another variant, the premises gateway is adapted for all-IP operation, such as for use with IP-based computers and IP set-top boxes, etc. Fully unified variants are also disclosed, wherein the DVR and/or STB functions are physically integrated within the premises gateway.

摘要： Live television broadcast and other information and entertainment programs, e.g., videos-on-demand (VOD), are provided to a user through a communications network, e.g., a cable network. A processing unit is employed at an headend of the communications network to respond to user requests for PVR-like functions, e.g., pausing, rewinding and fast-forwarding, to be performed on the program content being viewed. The processing unit in accordance with the invention causes a delivery of an appropriate version of the program content to meet such user requests.

摘要： In a broadband communications system, e.g., a cable system, a broadcast program stream is transmitted to broadcast programming content, and the broadcast program stream is recorded in a headend of the system to enable a user to perform network private video recorder (NPVR) functions (e.g., rewinding, pausing, and fast-forwarding) on the programming content in the recorded program stream. In accordance with the invention, a delay is introduced into the transmission of the broadcast program stream to reduce the unsynchronization between its transmission and that of the recorded program stream. In an illustrative embodiment, the amount of the delay is a function of the time required for recording the broadcast program stream and processing a user request for a recorded program stream. In another embodiment, the amount of the delay is predetermined.

摘要： In a broadband communications system, e.g., a cable system, programming content can be readily reserved and accessed for viewing using interactive program guides in accordance with the invention. Such programming content may include in-progress programs, future programs and previously broadcast programs which are recorded at a headend in the cable system, and which may or may not have overlapping broadcast times. In addition, the user may reserve programs at a set-top terminal, and may also do so remotely from the terminal through a communications network such as, the Internet, a public switched telephone network (PSTN), a wireless telephone network, etc.
