Apparatus and methods for packetized content delivery over a bandwidth-efficient network

Номер: US20120023535A1
Автор: Paul D. Brooks
Принадлежит: Time Warner Cable Inc

Methods and apparatus for providing packetized content to users via a bandwidth-optimized network. In one embodiment, legacy and IPTV streams are carried over the same switched digital infrastructure, and freely intermixed without regard to their encoding or type. A user's selection for IPTV content is transmitted to an IP proxy (such as a gateway apparatus or a headend server), then on to the switched digital server which causes provision of the requested content back to the proxy for formatting. The formatted content is then delivered to the requesting IP-capable device. The entire carrier class program stream is therefore available as IP-encapsulated content to the IP capable devices (and as legacy content to legacy devices) without any significant modifications to the network infrastructure or bandwidth penalty.

System and method to extend the data carrying capacity of a hybrid fiber cable (HFC) network by adding wideband RF signal capability above 1 GHz, and replacing at least some CATV active devices such as amplifiers with a new type of Coax Domain Node (CDN) device that acts to segment the CATV cable portion of the HFC network into a series of smaller domains. The CDN generally filter RF signals from 5-865 MHz, while amplifying and passing RF signals over 1 GHz. Upstream capability is enhanced because the CDN intercept 5-42 MHz upstream signals from each domain and convert to 1 GHz+ signals. Downstream capability is also enhanced because the CDN can take efficiently encoded 1 GHz+ digital data, QAM modulate it, and locally inject into each domain without crosstalk between domains. The system pushes data management and downstream from the head end to the CDN, creating more throughput.

The media session management of the invention encompasses a media server having access to multiple unicast-based media channels and a user terminal. The user terminal generates and transmits a generic, channel-transparent session request to the server. This request initiates a generic, channel-transparent media session setup procedure between the terminal and the server. The setup procedure involves exchange of requests and responses but no media channel is yet selected or notified at the server. Once the channel-transparent setup has been completed, the user terminal transmits a channel-specific rendering request for a desired media channel to the server. In a subsequent channel switch, the terminal simply transmits a new channel-specific request for a new channel to the server during the ongoing session and reusing the negotiated transport parameters of the channel-transparent setup procedure.

System and Method for Cloud-Based Live Media Ingestion and Transcoding

Номер: US20130308436A1
Автор: Hongbing Li
Принадлежит: FutureWei Technologies Inc

Embodiments are provided for a cloud-based reliable media ingestion and transcoding. The embodiments comprise an improved backup mechanism where each worker node, such as a virtual machine, physical machine, workstation, or server, in a cloud or Internet environment handles one streamed media/video channel transcoding and another streamed media/video channel ingestion backup. To reduce ingestion storage demands, the ingestion backup storage is based on a pre-determined relatively short-term sliding window. When an ingestion and transcoding worker node fails, a new worker node is brought up to take over from the failed worker node the live transcoding task of a first channel and the ingestion backup task of a second channel. Additionally, the new worker node retrieves backup data for the first channel from a third worker node and a central media storage to ensure seamlessly uninterrupted live ingestion and transcoding of the first channel, and continues the ingestion backup task of the second channel.
