摘要： A system and method for effectuating fast channel changes in an adaptive streaming environment. When a new stream of media content is started, a client device is adapted for sending a request for transmission of media content encoded at a select bit rate. Upon receipt of the encoded media content, the client device is operative to decode and render the media content immediately regardless of a buffer state associated with the client device's video buffer. The client device is further operative to send a request for streaming media content encoded at higher bit rates upon expiration of a specific period of time.
摘要翻译：一种用于在自适应流环境中实现快速信道变化的系统和方法。当开始媒体内容的新流时，客户端设备适于发送以选择比特率编码的媒体内容的传输请求。在接收到编码的媒体内容之后，客户端设备可操作地解码和呈现媒体内容，而不管与客户端设备的视频缓冲器相关联的缓冲状态如何。客户端设备进一步操作以在特定时间段到期时发送以更高比特率编码的流媒体内容的请求。

摘要： A system and method for managing adjacent channels in an adaptive streaming environment. One or more adjacent channels may be defined for a client device relative to a current streaming channel, wherein the client device is configured to pre-fetch metadata and initialization information for the defined adjacent channels based on bandwidth conditions, buffer conditions, etc. When a channel is changed, the client device is operative to use the pre-fetched data to quickly obtain encoded media content for rendering.

摘要： 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. When the viewer selects a video, the application accesses an equipment-mapping table, which associates the Internet device identifier with an STB identifier. The application then sends the STB identifier and a request for the selected video to the VOD server, which delivers the video to the STB over a television delivery system.

摘要： In one embodiment, a transaction server facilitates a purchase transaction for goods or services between users at two mobile phones. The Purchaser initiates a request for a purchase transaction to a server, and is provided with a unique code (“purchasing nonce”) that is uniquely associated with the request. The user of the first mobile phone provides the purchasing nonce to the Seller, who enters that value into the selling mobile phone. The selling mobile phone initiates a request to join the transaction as identified by the purchasing nonce. After confirmation of the Purchaser that the Seller can join the transaction, the Seller can itemize the goods for sale, which are electronically presented to the Purchaser for approval. After all items are selected, the Purchaser approves the transaction, and the transaction server can then transfers funds. An electronic receipt is provided to the Purchaser's mobile phone for confirmation.
摘要翻译：在一个实施例中，交易服务器便于在两个移动电话之间的用户之间的商品或服务的购买交易。买方向服务器发起购买交易的请求，并提供与该请求唯一相关联的唯一代码（“购买随机数”）。第一手机的用户向卖方提供购买现金，卖方将该价值进入销售手机。销售手机发起采购业务确认的交易请求。卖方确认买方可以加入交易后，卖方可以将出售的货物逐项提交给买方进行审批。选择所有项目后，买方批准交易，然后交易服务器可以转账。电子收据提供给买方的手机确认。

摘要： A centralized Content Management System (“CCMS”) facilitates management of packages comprising assets comprising meta-data and associated content of video programs for distribution to various types of service providers and equipment locations therein. The CCMS can receive meta-data and associated content, normalize the meta-data according to various formats based on various rules depending on where the meta-data and contents are to be distributed, and the distribute the content. The CCMS has various capabilities for managing packages, including adapting the meta-data and content for different types of equipment or individual locations based on rules for that service provider, thus providing an automated system reducing error and time in distributing video assets to a number of locations.

摘要： A scheme for modulating an adaptive bitrate (ABR) streaming client engaged in a current ABR streaming session. In one implementation, a determination is made whether a wireless UE device executing the ABR streaming client is approaching a radio white spot area. If so, a video buffer of the ABR client is configured to preload lower quality video segments to last for the duration of the radio white spot area. One or more ABR client controls may be selectively deactivated while the wireless UE device is in the radio white spot area.
