    • A method and apparatus for performing server-side splicing for live streaming media comprises receiving a request for media content from a client computer; accessing a media playlist comprising a plurality of universal resource identifiers (URIs) for each of a plurality of media content segments and consecutive sequence numbers defining an order in which the plurality of media content segments are to be viewed; accessing at least one additional content playlist for additional content to be spliced into the media content to be viewed; replacing a plurality of URIs of the media playlist with the URIs of the at least one additional content playlist to create a modified media playlist; and correcting a gap in sequence numbers that occurs in the modified media playlist when the number of URIs of the at least one additional content playlist is less than the plurality of URIs of the media playlist that are replaced.

    • QoS aware multi radio access point for operation in TV whitespaces is disclosed. The present invention relates to operation of access points and, particularly, to operation of access points in TV whitespaces. The AP is configured to intelligently choose the radios, determine available whitespaces in the spectrum and allocate radios to the available whitespaces in the spectrum. The method determines clients that need to be serviced by the AP and assigns each client associated with AP to one of the radios. In addition, the method also takes care of QoS requirements for different services and hence every service is addressed to satisfy its QoS requirements. The method ensures that there is maximum utilization of available whitespace spectrum by accounting for the spectrum specific characteristics. The method considers bands for operation are spread across the spectrum and allocates the clients based on the availability of bands throughout the spectrum.
    • 公开了在电视空白中操作的QoS感知多无线接入点。 本发明涉及接入点的操作,特别涉及电视空间中接入点的操作。 AP被配置为智能地选择无线电,确定频谱中的可用空白,并将频谱中的可用空格分配无线电。 该方法确定AP需要服务的客户端,并将与AP关联的每个客户端分配给其中一个无线电。 另外,该方法还可以满足不同业务的QoS要求,从而满足其QoS要求。 该方法通过考虑频谱特性来确保可用空白频谱的最大利用。 该方法将波段的操作分散在频谱上,并根据频谱范围内的频带的可用性来分配客户端。
