摘要： Methods and apparatus are provided for licensing service providers to process video, audio and/or multimedia content using a video processing device. A license key indicative of a license for an amount of bandwidth is generated. The license key is used at the video processing device to enforce the license based on whether there is sufficient licensed bandwidth available to accommodate a newly created output transport stream. If there is sufficient licensed bandwidth available, processing of the newly created output transport stream is allowed. If there is insufficient licensed bandwidth available, processing of the newly created output transport stream is denied. The service providers are charged a license fee to use the video processing equipment based on the licensed bandwidth.

摘要： The present invention provides a balanced video distribution system, as well as corresponding methods and apparatus, which utilize feedback from the channel multiplexers as well as rate estimation and predictive rate control. Packets of a video stream are received at an input buffer. A transmission deadline is determined for the packets. A fullness level of the input buffer is also determined. A future time at which said packets can be transmitted may be estimated based on the buffer fullness level. A bit rate of the video stream can be adjusted based on the estimated future time and the transmission deadline. For example, the bit rate may be adjusted in proportion to a difference between the estimated future time and the transmission deadline.

摘要： Methods, apparatus, and systems for inserting overlay content into a video signal are provided. An overlay content signal containing overlay content is received. In addition, a compressed video signal is received from a video source and decoded. An insertion window portion of the decoded video signal is identified. The overlay content signal and the insertion window portion of the decoded video signal are processed to produce a modified insertion window portion of the video signal. The video signal and the modified insertion window portion are then processed to produce a modified video signal. The data rate of the video signal may be modified during the overlay content insertion process.

摘要： A highly-efficient, cost-effective technique for multi-channel QAM modulation is described. The technique employs an inverse fast-Fourier transform (IFFT) as a multichannel modulator.. QAM encoding expresses QAM symbols as constellation points in the complex plane such that each QAM symbol represents a specific phase and amplitude of a carrier frequency to which it is applied. In multi-channel systems, the carrier frequencies are generally uniformly spaced at a channel-spacing frequency (6MHz, for digital cable systems in the United States). The IFFT accepts a set of complex frequency inputs, each representing the complex frequency specification (i.e., phase and amplitude) of a particular frequency. The inputs are all uniformly spaced, so assuming that the IFFT is sampled at a rate to provide the appropriate frequency spacing between its frequency-domain inputs, the IFFT will produce a time domain representation of QAM symbols applied to its various inputs modulated onto carriers with the desired channel separation. Since the channel spacing and the symbol rate are different due to excess channel bandwidth, interpolation is used to rectify the difference. An efficient scheme for combining this interpolation with baseband filtering and anti-imaging filtering is described.
摘要翻译：描述了一种用于多通道QAM调制的高效，经济有效的技术。该技术采用逆快速傅里叶变换（IFFT）作为多通道调制器.QAM编码将QAM符号表示为复平面中的星座点，使得每个QAM符号表示其所应用的载波频率的特定相位和幅度。在多通道系统中，载波频率通常以通道间隔频率（6MHz，对于美国的数字电缆系统）均匀间隔开。 IFFT接受一组复频率输入，每一个代表特定频率的复频率规格（即相位和振幅）。输入都是均匀间隔的，因此假设IFFT以一定速率进行采样以在其频域输入之间提供适当的频率间隔，IFFT将产生应用于其调制到载波上的各种输入的QAM符号的时域表示，所需的通道分离。由于信道间隔和符号率由于信道带宽过大而不同，因此使用插值来纠正差异。描述了将该内插与基带滤波和抗成像滤波相结合的有效方案。

摘要： A system and method are described for greatly increasing the number of services that can be encrypted with existing conditional access equipment. The method is most useful when many digitally compressed programs are encrypted at the same time. Only the most critical components of each compressed video, audio, or data stream are selected and then sequenced into a single stream. Additional formatting causes this sequence of segments from multiple sources to appear as a single continuous stream to the conditional access system. Once this stream has been encrypted, it is demultiplexed and the components are restored and resequenced into their respective programs. Messages such as the Entitlement Control Messages that are inserted into the stream by the encryption system, are also adjusted and included with each of the reconstructed programs. The technique not only allows encryption systems to be designed using less encryption hardware, but also simplifies the management of encryption sessions, particularly in on-demand programming applications.
摘要翻译：描述了用于大大增加可以使用现有条件访问设备加密的服务的数量的系统和方法。当许多数字压缩程序被同时加密时，该方法是最有用的。只有每个压缩视频，音频或数据流中最重要的组件被选中，然后排序成单个流。附加格式化会导致来自多个源的段序列显示为条件访问系统的单个连续流。一旦这个流被加密，它被解复用，并且这些组件被恢复并被重新排序到各自的程序中。诸如由加密系统插入到流中的授权控制消息的消息也被调整并且被包括在每个重构的程序中。该技术不仅允许使用更少的加密硬件来设计加密系统，而且简化加密会话的管理，特别是在按需编程应用中。

摘要： An advanced video multiplexer system designed and optimized for next generation on-demand video distribution is described. The system optimizes identifies a multi-program transport stream best able to accommodate new seesions based upon Quality of Service (QoS) and QAM utilization ratios. MPTS channels are rebalanced via re-grouping and transrating as necessary to optimize bandwidth utilization. Multiple video formats are supported via built-in transcoding. The multiplexer manages encryption resources and supports new sessions using previously allocated encryption resources where possible. Sessions can be grouped into encryption channels either by using a single authorization tier per channel policy, or by requiring all clients of the group to be in physically separated service groups. Encryption channels can be released when a channel no longer serves any clients or when one or more other channels that have been assigned the same entitlement can accommodate any remaining clients.

摘要： A highly-efficient, cost-effective technique for multi-channel QAM modulation is described. The technique employs an inverse fast-Fourier transform (340) as a multi-channel modulator. QAM encoding (304A-304n) expresses QAM symbols as constellation points in the complex plane such that each QAM symbol represents a specific phase and amplitude of a carrier frequency to which it is applied. In multi-channel systems (300), the carrier frequencies are generally uniformly spaced at a channel-spacing frequency (6MHz, for digital cable systems in the United States). The IFFT accepts a set of complex frequency inputs (308A), each representing the complex frequency specification (i.e., phase and amplitude) of a particular frequency. The inputs are all uniformly spaced, so assuming that the IFFT is sampled at a rate to provide the appropriate frequency spacing between its frequency-domain inputs, the IFFT will produce a time domain representation of QAM symbols applied to its various inputs modulated onto carriers with the desired channel separation.
