Abstract: A method is provided that is performed by a client device such a set top box when a viewer requests a program by initiating a channel change from a program guide or entering a channel through the user interface. The client device receives the user request and, in response, the client device transmits the request to the streaming server in the headend, which causes the streaming server to create a unicast catch up stream that commences with a key frame. The streaming server calculates the end point of the catch up stream and continues to send the catch up stream at a rate faster than real time. The client device receives the catch up stream and begins buffering it. While the catch up stream is being buffered the client device begins decoding and presenting the content. The client device receives the end of stream marker, and in response, sends a request to join the multicast stream.

Abstract: Aspects of the disclosure relate to control of transmission and consumption of content in a device, such as an end-point rendering device. The content can include linear-programming content assets and/or time-shifted content assets. Consumption can be mediated by a control device that can coordinate the functional interaction between the device and a content distribution network node or an access network node that can supply the content and related information.

Abstract: A microbrowser such as web-enabled wireless telephones and personal digital assistants allows a user to configure types of objects to be blocked from download including object memory consumption, display area, download time, and restrictions on animated images and executable scripts. Microbrowser state conditions such as battery level and network connection mode are considered when providing said limitations such that more restrictions may be placed during low battery periods to maximize battery life. For example, during low battery conditions or analog connection mode, a user may configure an enhanced microbrowser not to download advertisements, run scripts or animated objects in order to maximize remaining battery life. In another example, a user may configure an enhanced microbrowser to block the download of objects containing audio, or which will occupy more than a certain percentage of the available display area.

Abstract: A request is received from a subscriber of a video content network offering a switched digital video service. The request is to establish a new switched digital video session within a service group of the video content network. The service group includes both preferred and standard subscribers and has a plurality of existing sessions. It is determined whether adequate bandwidth is available to establish the new switched digital video session without tearing down any of the existing sessions. Responsive to the determination indicating that adequate bandwidth is not available without tearing down any of the existing sessions, at least one of the existing sessions is torn down. In this step, those of the existing sessions corresponding to the preferred subscribers are exempted from teardown. The new switched digital video session is established in accordance with the request. A switched digital video control apparatus, a set-top terminal, and a system are also disclosed.

Abstract: The dynamic probability admission control policy for distributed video provides a method that decides in a Video on Demand (VOD) system which content requests can be admitted and which requests should be rejected to maintain Quality of Service (QoS). Requests for popular and expensive movies should not be rejected on the behalf of unpopular movies to generate more revenue. The dynamic probability admission control policy combines a shared resource admission control and a class-based admission control. Moreover, dynamic probability is used to access shared resources, such as ports and bandwidth. A nonlinear dynamic probability function is used for allocation of ports/bandwidth. The dynamic probability admission control policy improves performance of all the request classes, as well as overall system performance.

Abstract: A system and method for controlling network bandwidth that uses a timer to monitor the length of time that a set top box is set to a channel and, in response to the timer reaching a time limit, requesting a response from a user to verify that the channel is still being watched. If a response is not received with a specified time duration, the signal for the IPTV channel may be disconnected. The system may be configured to include “thin client” middleware on a network server or “thick client” middleware on a set top box, for example, to operate in conjunction with a network server.

Abstract: When the user initiates the retrieval of the primary content information item by means of entering a user input into the data processing system, e.g. zapping a digital TV that switches channels upon receipt of the user input, he/she has to wait a noticeable time before the rendering and play-out of the primary content information item actually starts. The length of the delay is predicted, on the basis of which one or more secondary content items are rendered and played out to the user during this delay. The invention can also be used for bridging the waiting time in an online ordering system, when loading a program on a personal computer, and in an IMS-based IPTV network.

Abstract: A system, method, and web-based application platform enabling a television viewer to utilize an Internet device to request a Video-On-Demand (VOD) server to stream a selected video to the viewer's Set Top Box (STB). An Internet Protocol (IP) connection is established between the Internet device and an application executing at a web site, and an Internet device identifier is passed to the application. The application communicates with the VOD server to obtain a listing of available videos, and provides the listing to the Internet device.

Abstract: In a system that is capable of operating in a broadcast mode and a switched mode, it is advantageous to be able to shift program delivery between the two modes. Thus when one video program is being delivered to at least a first customer in a first mode, this program may be delivered to at least a second customer in a second mode that is different from the first mode. In this manner, the video program that is being delivered to first customer will be maintained in the original mode while new requests for this program will be served in a different mode until the delivery of the program to the first customer has been completed. In other words, legacy program delivery is maintained until the program delivery has been completed or otherwise terminated, while delivery of the program in response to new requests for the same program will be delivered in a different mode instead.

Method comprises forming a database of content units to the user or user group, which formed a particular list. On a basis of list make more precise calculation of the required bandwidth in the system by building a queue of orders for the reservation rate for each ordered content unit for each user or user group. Combine the same orders and multicasting of the same custom content units to the user or user group. Carry out the automatic switching user access device (e.g. Set Top Box) on a content channel that has broadcast content unit in accordance with his request.

Abstract: A server resource provides notification to subscribers in a respective network environment that the content is available for retrieval at a particular bit rate (e.g., a promotional bit rate) or particular level of quality (e.g., promotional level of quality) amongst multiple levels of quality for a limited duration of time. For example, an especially high level of quality (or bit rate) of the content may be available only for the limited duration of time. After making the especially high level of quality of content available for retrieval during a promotional period, the content may be subsequently available for retrieval only at lower levels of quality. Accordingly, one or more configurations as discussed herein include changing the ability to access content encoded at different levels of quality over time.
