The present invention is a video on demand service enabled from a near video on demand service. A desired program is split into portions, or clips. The first clip is delivered a priori to the customer's Digital Video Recorder (DVR) using a hidden channel and it is made available for purchase on demand. The remaining portion is broadcast regularly using the start time of the Near Video On Demand service, for as long as the program is available for Video On Demand purchase. Upon purchase, the remaining portion is authorized for capture by the DVR. The clips are spliced together upon playback to form a complete program.

A near video-on-demand (VOD) service enabled using a digital video recorder (DVR) for the simultaneous storage and playback of multimedia data. A DVR is connected over a network to a multimedia network source. A VOD selection is requested by the DVR from the network source. A multimedia data signal is received by the DVR from the network source. The data signal contains the requested VOD selection. A first received portion of the received data signal is stored on the DVR. The first received segment is played by the DVR for display on a display device. Simultaneously during the playing of the first received segment, a second received segment of the received data signal is received from the network source and stored on the DVR while the first received segment is played the display device. Thus, the requested VOD selection begins playing on the display device prior to the reception of the entire compressed multimedia data signal so that a requested VOD selection can begin being displayed nearly instantaneously after the request for it is made. A video-on-request (VOR) service is also enabled using a DVR. VOR selection data is received by a centralized database device, such as a network server, from a plurality of users. Each VOR selection data includes at least one requested video selection and video recorder identifying information for identifying each particular video recorder. A transmission priority of requested video selections is determined dependent on the frequency of requests received from the plurality of users. A transmission channel and time is determined based on the transmission priority. DVR control signals are transmitted to automatically tune in the determined transmission channel at the determined transmission time and record the particular video selection.

A method, apparatus and system for redundancy backup of video services are provided. The method includes: receiving a data stream from a video server; stopping delivering the data stream to an Internet Protocol (IP) network if determining that the data stream is abnormal; and triggering the IP network to change delivery of the data stream over to a redundant video server. With the method provided by the present invention, when the data stream played by the Near Video on Demand (nVOD) system is detected as abnormal, a route changeover can be completed so that the program stream of a redundant nVOD server is delivered to the IP network.

The embodiment of the invention discloses a method, a device and a system for realizing interactive near video-on-demand (NVOD) channels, which relate to the field of the NVOD channels and can realize the interactive NVOD channels at relatively low operating cost. The method comprises the following steps of: sending the metadata of an NVOD program to user equipment; receiving a playing request of the NVOD program sent by the user equipment, wherein the playing request comprises the NVOD program selected in the metadata of the NVOD program by a user through the user equipment; and determining the next NVOD program to be played according to the playing request, and sending a media stream of the determined NVOD program in a multicasting / broadcasting form. The method, the device and the system are mainly applied to the NVOD channels and can be applied to an Internet protocol television (IPTV) system based on an IP multimedia subsystem (IMS).

An efficient near video on demand (NVOD) service for various client environments is provided. The NVOD service method for transmitting video data including moving pictures to a plurality of clients in a network includes identifying a relative network bandwidth “m” of a client with respect to a video playout bandwidth, dividing the video data into data segments having different sizes according to the relative network bandwidth “m” and transmitting the data segments to the client through a plurality of channels.

The present invention discloses a method for transmitting Near Video on Demand (NVoD) using Catch and Rest (CAR) and sub-channels which includes: dividing an L-sized content into N segments using the CAR broadcasting scheme, allocating the segments to K channels including a replicate channel, and broadcasting the segments; dividing a first segment S1R (SiR represents an i-th segment of a regular channel) into Nsb sub-segments again at given bandwidth using the harmonic broadcasting scheme, and dividing an i-th sub-segment Sisb into i segments again; broadcasting the sub-segments {Si.1sb, . . . , Si.isb} in n sub-channels; and adding the segments {S2R, . . . , SNR} to a sub-layer and broadcasting the segments, the first segment broadcast in the first channel being divided and allocated to a few sub-channels, the succeeding segments broadcast in the other channels being just shifted and broadcast.
