Abstract: 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.

Abstract: Program content is received at a headend of a broadband communication system, along with data concerning scheduled start and end times of the program derived from electronic program guide (EPG) data. After the program is broadcast, the actual broadcast start and end times of the program are compared with the corresponding scheduled times to determine whether there is any start and/or end time variance. If a time variance is determined, the content of the program is redefined to include only its supposed content. The redefined content is then made part of an asset for later retrieval and distribution.

Abstract: A resident application and a second application are provided in a set-top terminal to receive a TV broadcast service and network personal video recorder (NPVR) service, respectively. The resident application is suspended in favor of the second application when a user changes from a broadcast channel to an NPVR enabled channel, and vice versa. In an embodiment where a digital video recorder (DVR) set-top terminal is used, a DVR server therein provides trick mode functions (pause, rewind and fast-forward) before an NPVR session, e.g., a Look Back session, is established. In another embodiment, during an NPVR session the DVR server plays back recorded programming content downloaded from a communications network, and provides trick mode functions as well.

Abstract: In order to efficiently utilize the limited transmission bandwidth of a communications network, e.g., a cable network, guide data for constructing an interactive program guide (IPG) is delivered to a set-top terminal using different methodologies. For example, the guide data associated with those programs which are likely of interest to a user is automatically provided piecemeal in a broadcast stream. The set-top terminal, along with other terminals, may retrieve from such a broadcast stream some or all of the guide data therein over time, which is cached in the terminal in anticipation of a user's invocation of an IPG. On the other hand, the guide data associated with those programs which are less likely of interest to a user is furnished upon request by the set-top terminal needing such guide data to realize an IPG desired by the user. In addition, guide data for each program may be divided into detail guide data providing details of the program (e.g.

Abstract: Although personal video recorders (also known as digital video recorders) provide certain conveniences to viewers of programming content, such devices facilitate manipulation or “skipping” of commercials, frustrating the intent of the advertisers of the commercials. In accordance with the invention, when a user fast-forwards (rewinds) a commercial, alternate commercial(s) may be accessed for display in place of the original commercial, which provides a full impression of the goods and service promoted, otherwise impossible to appreciate at the fast-forward (rewind) speed. The duration of the alternate commercial(s) corresponds to the duration of the original commercial at the fast-forward (rewind) speed controlled by the user. With the invention, the user advantageously realizes the convenience of manipulating programming content, and at the same time can appreciate the full impression of an alternate commercial to the original commercial, albeit in a shorter duration.

Abstract: In a cable network providing, among others, interactive video services, data cells carrying real-time data concerning, e.g., trick mode commands (pause, rewind and fast-forward) initiated by a user are instantly transmitted to a headend facility for immediate processing. The invention is premised upon a recognition that such real-time data typically does not fully utilize the transport capacity of the data cells. In accordance with the invention, non-real-time (NRT) data to be transmitted to the headend facility, although accorded a lower priority than the real-time data, is inserted into those underutilized data cells before their transmission, thereby fully exploiting the transport capacity of the data cells.

Abstract: A method of generating a program signal stream comprises creating a sequence of serial programs that include a first event and a second, later occurring event and inserting a plurality of messages in the sequence of serial programs, between the first event and the second event. The messages may be indicative of a time to the second event, as measured from each respective message of an elapsed time since the first event, to each respective message. Alternatively or in addition, the messages may be at equal time intervals between the first event and second events. The first and second events may be the start and end of a program or a program portion, such as a chapter, an advertisement, unscheduled content or an entire program, for example. At least one message indicative of the time to the second event may be inserted in the sequence of serial programs prior to the first event.

Abstract: 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.

Abstract: A resident application (RA) in set-top terminals (STTs) is updated by providing an upgrade channel application (UCA) over a network. Those STTs that are selected to receive the UCA are identified. The selected STTs download the UCA from the network. Once the UCA begins to execute on an STT, it retrieves the user parameters stored in the STT, and transmits them to a remote location for storage. A new RA is then installed in the STT. The original user parameters are converted at the remote location to become compatible with the new RA. The converted user parameters are transferred to the STT for use by the new RA.

Abstract: An example of a method of correcting an audio level of a stored program asset comprises retrieving a stored program asset having audio encoded at a first loudness setting. Dialog of the audio of the asset is identified, a loudness of the dialog is determined and the determined loudness is compared to the first loudness setting. The asset is re-encoded at a second loudness setting corresponding to the determined loudness, if the first loudness setting and the second loudness are different by more than a predetermined amount. The determined loudness is preferably a DIALNORM of the dialog. The asset may be stored with the re-encoded loudness setting. The method may be applied to programs as they are being received from a source, as well. Aspects of the method may also be applied to programs to be provided by a source. Systems are also disclosed.

Abstract: In a broadband communications system, e.g., a cable system, programming content can be readily reserved and accessed for viewing using an interactive program guide, a network home graphic user interface (GUI), Quick View Guide, etc., 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.
